PRECIZNOST ASTRANDOVOG TESTA U PROCJENI AEROBNOG KAPACITETA KOD VESLAČA I TRKAČA VETERANA - ŠTO NAM GOVORI STATISTIKA? ACCURACY OF SUB MAXIMAL CYCLO-ERGOMETRY IN SENIOR ROWERS AND RUNNERS - WHAT CAN WE CONCLUDE BASED ON THE STATISTICS? Mikulić, Pavle Ružić, Lana Sporiš, Goran Astrandov test; spiroergometrijski test; veslači; trkači; sportska rekreacija Astrand cycle ergometry test; maximal ergometry test; rowers; runners; sports recreation Astrandov test vjerojatno je najpoznatiji i najčešće primjenjivani submaksimalni test procjene aerobnog kapaciteta. U ovom istraživanju pokušala se procijeniti njegova preciznost na osnovu usporedbe rezultata testa sa rezultatima istih ispitanika dobivenih pri direktnom mjerenju tj. maksimalnom spiroergometrijskom testu opterećenja, testu čiji se rezultati smatraju objektivnim pokazateljima funkcionalnog statusa. Uzorak ispitanika sastojao se od 46 veslača i 22 trkača muškog spola, kronološke dobi 35-65 godina koji su aktivni u veslačkom odnosno trkačkom treningu rekreacijskog karaktera. Spiroergometrijski test opterećenja obavljen je na veslačkom ergometru za veslače i na pokretnom sagu za trkače. Utvrđeni su osnovni deskriptivni parametri, Pearsonov koeficijent korelacije (r=0.68 za veslače i r=0.56 za trkače), provedena simple regresijska analiza te provedeni T-test za zavisne uzorke i Fisherov F-test. Kako rezultati T-testa za zavisne uzorke ukazuju da nema značajnih razlika između procijenjenog i direktno izmjerenog maksimalnog primitka kisika (p=0.42 za veslače i p=0.27 za trkače) moglo bi se zaključiti da se procjena može upotrebljavati umjesto direktnog mjerenja. Pravi uvid u stvarnu situaciju daju tek regresijska analiza i F-test. Rezultati F-testa ukazali su na statistički značajnu razliku između rezultata u Astrandovom testu i u spiroergometrijskom testu, kako kod veslača (p=0.00) tako i kod trkača (p=0.01). Regresijska analiza ukazala je na statistički značajno sudjelovanje Astrandovog testa u predikciji stvarnog VO2max, ali ipak uz vrlo malu količinu zajedničkih informacija (R2= 0.46 za veslače, R2= 0.31 za trkače). U zaključku, primjena Astrandovog testa ima ograničenu vrijednost, test nije prikladan za procjenu aerobnog kapaciteta kod spomenutih populacija, a jednostavni testovi razlika između skupina koji su primjenjivani u utvrđivanju pouzdanosti Astrandovog testa ne daju pravi uvid u stvarno stanje koje je ponekad vidljivo već i iz samih izvornih podataka. Ograničenje ovog istraživanja je u mogućnosti generalizacije rezultata ovog istraživanja i na cjelokupnu tjelesno aktivnu mušku populaciju srednje životne dobi kod kojih je Astrand često metoda izbora zbog submaksimalnog karaktera. Astrand cycle ergometry test is probably the most famous and most frequently used sub maximal test aimed at evaluation of the aerobic capacity. In this research the accuracy of test was evaluated based on results comparison with the results obtained during maximal ergometry test, the test which is considered to be an objective indicator of functional status of the individual. The sample consisted of 46 rowers and 22 runners. All the examinees are males in their middle age (35-65 yrs), who are at least twice per week active in rowing or running recreational training sessions. The maximal ergometry test was conducted using the rowing ergometer for the sample of rowers, and treadmill for the sample of runners. Basic statistical parameters were calculated followed by Pearson correlation coefficient. Simple regression analysis was performed and Student T-test and Fisher F-test were used to verify the obtained results. The results pointed out statistically significant, but low to moderate relationship between Astrand test results and maximal ergometry results (r=0.68 for rowers and r=0.56 for runners). Simple regression analysis pointed out statistically significant prediction of true VO2max based on the Astrand test results, but the shared variance turned out to be relatively low (R2=0.46 for rowers, R2=0.31 for runners). T-test results pointed out no statistically significant difference between Astrand and maximal ergometry results in both of the observed groups (p=.42 for rowers and p=.27 for runners), while stronger F-test proved otherwise (p=.00 rowers; p=.01 runners). Acquired results confirmed that Astrand test can not be considered an accurate test for evaluation of the aerobic capacity in recreational rowers and runners. For further research, it remains to be investigated can these results be translated to a broader population of the physically active men in their middle age Croatian Olympic Committee 2005-12-22 text pdf http://hrcak.srce.hr/563 http://hrcak.srce.hr/file/1171 Croatian Sports Medicine Journal (hsmv@kif.hr); Vol.20 No.2; ISSN 0354-0766 (Print) hr The full text of the papers published in this journal is intended for personal, professional and scientific use, as well as educational purposes, with regard to the authors and publishers rights.

DISMORFIZMI PRSNOG KOŠA (PECTUS CARINATUM I PECTUS EXCAVATUM) U DJECE I MLAĐIH ADOLESCENATA DISMORPHISMS OF THE THORAX (PECTUS CARINATUM AND PECTUS EXCAVATUM) IN CHILDREN AND YOUNGER ADOLESCENTS Kosinac, Zdenko učestalost; dismorfizmi prsnog koša; liječenje occurence; thorax dismorphisms; treatment Rezultati somatskog pregleda svekolikog uzorka 180 učenika nižih razreda osnovnih škola, 160 učenika viših razreda osnovnih škola i 226 učenika nižih razreda srednjih škola u Splitu ukazuju da su dismorfične promjene prsnog koša relativno rijetka pojava u djece ove životne dobi (one ne prelaze više od 20%). S gledišta vremenske dinamike (životne dobi i razine obrazovanja) prepoznatljiva je jedna pravilnost u procesu morfološke transformacije posture prsnog koša koju treba poznavati i uvažavati jer ona može biti od velikog dijagnostičkog, prognostičkog i kineziterapijskog značenja. Ovisno o lokalizaciji i veličini izbočenosti ili udubljenja prsne kosti mogući su fiziološki poremećaji pojedinih organa smještenih u prsnoj šupljini. Deformacije prsnog koša mogu pratiti snažni psihoemocionalni konflikti i poremećaji. Izbor metode liječenja ovisi o stupnju i obliku deformiteta ali i osobnim karakteristikama. Kineziterapija kao metoda izbora uz uporabu prsnog steznika (neoperativno liječenje) u tretmanu fleksibilnih oblika izbočenih prsiju (pectus carinatum) i udubljenih prsiju (pectus excavatum) ima svoju terapijsku opravdanost i prednost pod pretpostavkom da dijete sa početnim indikacijama deformiteta prsiju bude što ranije otkriveno i što ranije podvrgnuto složenim kineziterapijskim tretmanima. The obtained results on a sample of 180 pupils of primary school lower grades, 160 pupils of primary school higher grades and 226 students of the first and second grades of secondary school in Split give us the freedom to conclude: dismorphisms of the thorax occur relatively seldom in children and younger adolescents, which are, due to the estetic nature of that deformity, wrongfully neglected, compared to dismorphic changes of the posture, which are much more exposed. Depending on the place and size of the convexity or concavity of the thorax bone the physiologic deformities of certain organs placed in the thorax are possible to occur. In younger adolescents the thorax deformities can cause strong psychoemotional conflicts. The choice of which method of treatment to use depends on the level and shape of the deformity, as well as on the personal characteristics. Kinesiotherapy as a method of choice together with the use of thorax stays (inoperable treatment) in the treatment of flexible forms of pectus carinatum and pectus excavatum can be justified and it can be given an advantage to, concerning that the child with the beginning indications of the deformity of the chest is discovered as early as possible and is treated with the complex kinesiotherapeutic treatments.

METRIJSKE KARAKTERISTIKE NOVO KONSTRUIRANOG TESTA ZA PROCJENU BRZINE FREKVENCIJE POKRETA THE METRIC CHARACTERISTICS OF THE NEW CONSTRUCTED SPEED OF MOVEMENT'S FREQUENCY TEST Munivrana, Goran Čavala, Marijana Viskić-Štalec, Nataša novo-konstruirani test; brzina frekvencije pokreta; metrijske karakteristike; učenice new constructed test; speed of movement’s frequency; metric characteristics; female students Osnovni cilj ovog istraživanja, provedenog na uzorku od 46 ispitanica, učenica 5-ih razreda OŠ «Mertojak» u Splitu, bio je utvrditi metrijske karakteristike jednog novo konstruiranog testa za procjenu brzine frekvencije pokreta. Rezultati ispitanica na novom testu (TAP. KLUP.) su normalno distribuirani te on ima zadovoljavajuću osjetljivost, a pokazao je i solidnu pouzdanost (Cronbach´s alpha=0,89) koja je ipak nešto slabija u odnosu na preostala tri testa. Relativno visoka korelacija čestica sa prvom glavnom komponentom također ukazuje na visoku homogenost svih korištenih testova, pri čemu novi test pokazuje nešto slabiju homogenost u odnosu na ostala tri testa. To je prije svega uzrokovano slabijom povezanošću njegove prve čestice s faktorom što se može pripisati čimbeniku učenja, jer su učenice po prvi put izvodile taj test. Tome u prilog govori i homogenizacija rezultata u slijedećim česticama. Utvrđena je i faktorska valjanost testova, odnosno dobila se jedna latentna dimenzija na koju su značajno projicirani svi testovi uključujući i novo-konstruirani. Novi test, taping na klupici (TAPKLU) ima nešto slabiju povezanost s faktorom od testova taping rukom (MBFTAP) i taping nogom (MBFTAN), ali je u razini testa taping nogama o zid (MBFTAZ), koji mu je, poradi nešto veće koordinacijske složenosti u odnosu na testove MBFTAP i MBFTAN, po strukturi i najbliži. Iz svega može se zaključiti da novi test pokazuje dobre metrijske karakteristike za ovaj uzorak ispitanika The primary objective of this research conducted on the sample of 46 subjects, all 5th grade female students of the Elementary School «Mertojak» in Split, was to establish metric characteristics of the new constructed test for measuring of speed of movement’s frequency. New test is satisfactory sensitive because results of students in the test are normally distributed and it also shows the satisfactory level of reliability (Cronbach´s alpha=0,89), but it’s still less reliable in comparison with other three tests. Relatively high correlation of items with first principal component also shows high homogeneity of all tests, although new test has showed little less homogeneous then the other three tests. That is, first of all, caused by weaker correlation of test’s first item with factor. It could be explained with fact that it was a first time for students to perform that test, so it was probably due to a learning process, and much higher correlation of other two items with first principal component confirms that theory. Also the factor validity of all tests was confirmed and one latent dimension on which all tests, including new one, were significantly projected has formed. New test taping on the bench (TAPKLUP) is slightly less correlated with factor than hand taping (MBFTAP) and foot taping (MBFTAN) tests, but in about same level with foot taping against the wall (MBFTAZ) test which is, because of it’s larger co-ordinating complexity, most similar to the new constructed test. It’s possible to conclude that the new test shows good metrical characteristics for this sample of subjects Croatian Olympic Committee 2005-12-22 text pdf http://hrcak.srce.hr/584 http://hrcak.srce.hr/file/1210 Croatian Sports Medicine Journal (hsmv@kif.hr); Vol.20 No.2; ISSN 0354-0766 (Print) hr The full text of the papers published in this journal is intended for personal, professional and scientific use, as well as educational purposes, with regard to the authors and publishers rights.

UTJECAJ KOFEINA NA TJELESNU AKTIVNOST EFFECT OF CAFFEINE ON EXERCISE Sorić, Maroje kofein; kava; izdržljivost; sportaši caffeine; coffee; endurance; athletes Kofein je gotovo neizbježan sastojak naše svakodnevne prehrane. Donedavno je pretjerana upotreba kofeina smatrana dopingom. Od 2004. godine kofein nije više na listi zabranjenih sredstava Međunarodnog olimpijskog odbora. No, i prije te promjene interes za ergogena svojstva kofeina bio je velik. U ovom će se preglednom članku ukratko prezentirati ergogena svojstva kofeina, kao i mehanizmi koji bi im mogli biti u podlozi. Osvrnut ćemo se i na doze kofeina i tempiranje njegove primjene, ali i na moguće neželjene učinke kofeina. Na kraju, razmotrit će se neke etičke dvojbe oko uporabe kofeina u sportu Caffeine is an almost inevitable part of our daily diet. Until recently, caffeine was banned from sports. However, in 2004 caffeine was taken off the list of banned substances of the International Olympic Committee. Even before that, caffeine has been widely used as an ergogenic substance. Therefore, we will review its ergogenic benefits and underlying mechanisms. Dose and timing of ingestion will also be mentioned, as well as possible adverse affects of caffeine. Last but not least, we will address some ethical doubts about its ab(use) by athletes in order to improve performance.

ISTOZNAČNICE U STRUČNOM JEZIKU MEDICINE, STOMATOLOGIJE I KINEZIOLOGIJE SYNONYMS IN THE TECHNICAL LANGUAGE OF MEDICINE, DENTAL MEDICINE AND KINESIOLOGY Štefić, Lidija Krauth, Branka Omrčen, Darija istoznačnice; semantičko polje; medicina; stomatologija; kineziologija synonyms; semantic field; medicine; dental medicine; kinesiology Pojava velikog broja sinonima česta je u jeziku medicine, stomatologije, kineziologije itd. Ti nazivi imaju svoje podrijetlo u klasičnim jezicima latinskom i grčkom, a a ponekad se supojavljuju s nazivima u nekom prirodnom jeziku. Ekonomičnost izričaja je važno obilježje znanstvenog jezika. Osnovno terminološko načelo koje treba poštovati je odabir jednoga naziva i njegova pravilna uporaba. Uporaba nekoga naziva može nametnuti drugačiji odabir, naime, nazivi se odabiru između postojećih istoznačnica na način da se preferira uporaba češće korištenog naziva. Sinonimi se razlikuju s obzirom na svoja semantička polja. Stoga ih je potrebno pažljivije definirati kao riječi koje imaju zajedničko osnovno značenje The occurrence of a great number of synonyms is frequent in the language of medicine, dental medicine, kinesiology, etc. Those terms have their etymology in classical languages, namely, Greek and Latin, and they sometimes co-occur with terms originating in an indigenous language. The economy of expression is an important feature of scientific language. The basic terminological principle to be followed is to choose one term and to use it consistently. The usage of a term may impose a different selection, namely the terms are selected among the existing synonyms in such a way that the most frequent term is preferred. Synonyms differ as for the range of their semantic fields. They should therefore be more carefully defined as words having a common prototype or core meaning Croatian Olympic Committee 2005-12-22 text pdf http://hrcak.srce.hr/589 http://hrcak.srce.hr/file/1220 Croatian Sports Medicine Journal (hsmv@kif.hr); Vol.20 No.2; ISSN 0354-0766 (Print) hr The full text of the papers published in this journal is intended for personal, professional and scientific use, as well as educational purposes, with regard to the authors and publishers rights.

ZNANJE TRENERA O SPORTSKOJ PREHRANI SPORT NUTRITION KNOWLEDGE OF COACHES Matković, Bojan Knjaz, Damir Cigrovski, Vjekoslav prehrana; znanje o prehrani; treneri; košarka; skijanje nutrition; nutrition knowledge; basketball; skiing; coaches Prehrana sportaša interes je znanstvenika već desetljećima, od kada postoje takmičenja prisutno je pitanje što jesti i piti da bi se poboljšao rezultat. Danas sigurno znamo da prehrana sportaša utječe na njihovo zdravlje, sastav tijela i masu, iskoristivost energenata za vrijeme aktivnosti, oporavak i izvedbu. Cilj ovog istraživanja je utvrđivanje znanja o prehrani kod sportskih trenera – trenera košarke i skijanja. Uzorak ispitanika bio je sastavljen od hrvatskih košarkaških trenera (N=32) i trenera skijanja (N=24). Znanje o sportskoj prehrani utvrđeno je putem odgovarajućeg upitnika. Upitnik o znanju o sportskoj prehrani bio je koncipiran tako da utvrdi znanje sportaša o prehrani općenito, o sastojcima neophodnim da bi sportaši osigurali dovoljne količine energije za trening i natjecanja, o dodacima prehrani, o obrocima prije treninga i natjecanja, kao i tijekom oporavka te o značaju tekućine, dehidraciji i rehidraciji za vrijeme treninga i natjecanja. Anketa je bila anonimna. Dobiveni podaci su obrađeni odgovarajućim statističkim postupcima, pomoću statističkog paketa STATISTICA. Sagledavajući rezultate u cjelini može se zaključiti da je poznavanje prehrane od strane košarkaških i skijaških trenera zadovoljavajuće. Od ukupno 1232 ispravna odgovora oni su ostvarili 959 ili 77.8% ispravnih odgovora ili u prosjeku po pojedinom pitanju 43 ispravna odgovora uz raspon od 24 točna odgovora pa do punih 56. Međutim kada se pogledaju pojedinačni odgovori onda se zadovoljstvo zbog relativno visokog postotka ispravnih odgovora donekle gubi jer se mogu jasno uočiti neke značajne manjkavosti u sveukupnom znanju i to o vrlo bitnim pitanjima prehrane sportaša. Upravo stoga može se ustvrditi da bi sportski nutricionist trebao biti jedan od važnih čimbenika u trenerskom timu. The nutrition of athletes has been of interest to scientists for decades and since the origins of sports competitions the questions about what to eat and what to drink in order to improve performance have been raised. Today there are scientific proofs that an adequate dietary habits influences in a large extent to an athlete's health, body composition, and energetic pathways during the activity as well as during the competition or recovery. Athletes should be well informed about the food groups, caloric intake, and daily meal schedule. As the previous investigations showed, the athletes obtain most of their knowledge about nutrition from their coaches, especially physical conditioning coaches. The major aim of this study would be determination of the level of knowledge about nutrition. The sample consisted of 32 basketball and 24 skiing coaches from Croatia. The knowledge about the sports nutrition was tested by means of questionnaire. The questionnaire was constructed based on the results of previous studies conducted at the Faculty of Kinesiology and the results from international studies. It consisted of items determining the general knowledge about nutrition, nutritional ingredients needed for providing adequate energy level in sports, items about supplements, meal schedule before training and competition and recovery, and of items testing the knowledge about importance of liquids, dehydration and rehydration during and after training and competition. Surveys were anonymous and the data obtained were analysed by statistical software STATISTICA for WINDOWS. According to the results obtained we concluded that the level of knowledge about nutrition basketball and skiing coaches globally is satisfactory but inadequate in some segments, especially in the part of nutritional supplements and energy sources. It also can be concluded that the sources of information for nutritional facts that coaches use are not always scientifically justified.

POUZDANOST NAVIKULARNOG DROP TESTA PRI MJERENJU PRONACIJE STOPALA INTRA-RATER RELIABILITY OF USING THE NAVICULAR DROP TEST FOR MEASURING FOOT PRONATION Vauhnik, Renata Turk, Zmago Pilih, Iztok A. Mičetić-Turk, Dučanka noga; pronacija; navikularni drop test; test intra-rater pouzdanosti; korelacijski koeficijent foot; morphology; pronation; navicular drop test; intraclass correlation coefficient Navicular drop test je upotrebljen kao indikator pronacije noge. Definira se kao razlika između visine navikularke od poda, u sjedećem položaju kad je noga na podlozi u subtalarnoj neutralnoj poziciji, i konačnom opterećenju navikularke u relaksiranom položaju. Mjerenje predstavlja pomak sagitalne ravnine navikularne kosti iz neutralne pozicije u stojeću neutralnu poziciju. Svrha studije je testiranje pouzdanosti intra-rater testa za mjerenje navikularnog pada. U studiji je sudjelovalo četrnaest zdravih osoba, prosječne starosti 34,5±5,68 godina. Pronacija noge je ocjenjena upotrebom navicular drop testa. Mjerenja navikularnog pada su izvršena tri puta na svakoj nozi, svaki drugi dan. Rezultati su bili statističko analizirani, upotrebom SPSS (SPSS 10, za Windowse).Koeficijent korelacije između različitih parametara je bio 0,78 i 0,88 za dominantnu odnosnu nedominantnu nogu. Rezultati pokazuju umjerenu do dobru intra-rater pouzdanost za upotrebu navikularnog drop testa za mjerenje pronacije noge u kliničkim okvirima. The navicular drop test was used as an indicator of foot pronation. It is defined as the distance between the original height of the navicular from the floor, with the foot on the floor in sitting in the subtalar neutral position, and the final weight-bearing position of the navicular in relaxed stance. This measurement is thought to represent the sagittal plane displacement of the navicular bone from a neutral position to a relaxed standing position. The purpose of this study was to test intra-rater reliability of a method for measuring the navicular drop. Fourteen healthy subjects, mean age 34.5±5.68 years, participated in the reliability study. Foot pronation was assessed using the navicular drop test. Measurements of the navicular drop were performed three times on each foot, one day apart and were averaged for statistical analysis. Statistical analysis was performed using SPSS (SPSS 10, for Windows). Intraclass correlation coefficients were 0.78 and 0.88 for the dominant and non- dominant leg respectively. The results demonstrated moderate to good intra-rater reliability for use of the navicular drop test for measuring foot pronation in clinical settings.

BIOMEHANIČKO VREDNOVANJE DUBINSKIH SKOKOVA U PRIPREMI SKAKAČA U DALJ BIOMECHANICAL EVALUATION OF THE DROP JUMP EXERCISES IMPLEMENTED IN PREPARATION OF LONG JUMPERS Antekolović, Ljubomir Kasović, Mario Marelić, Nenad kinematika; sila reakcije podloge; elektromiografija; dubinski skokovi; skok u dalj kinematics; ground force reaction; electromyography; drop jumps; long jump Cilj ovog istraživanja je opis i standardiziranje postupka korištenja osnovnih biomehaničkih tehnika za istovremeno dobivanje kinematičkih, kinetičkih i EMG podataka kod vježbi dubinskih skokova. Mjerenje dubinskih skokova izvršeno je korištenjem piezoelektrične platforme za mjerenje sile reakcije podloge, uređaja za mjerenje EMG aktivnosti muskulature i akvizicijom video signala na temelju kojih je kasnije učinjena kinematička analiza.Dubinske skokove izvodilo je pet ispitanika, skakača u dalj, koji su vrhunski natjecatelji, a analizirane vježbe često su primjenjivane u tehnologiji atletskog treninga.Analizirane biomehaničke varijable iskazuju visoku zahtjevnost izvođenih zadataka na lokomotorni sustav ispitanika. Rezultati ukazuju na veliku vertikalnu silu reakcije podloge na svim razinama opterećenja (visinama saskoka), što je pokazatelj da se korištenim vježbama dubinskih skokova uspješno može ostvariti opterećenje kao i kod skokova u dalj (vrijednosti vertikalne sile rakcije podloge kreću se od 3500 do 6300N). Rezultati horizontalne sile reakcije podloge očekivano su niži zbog znatno manje horizontalne brzine kretanja skakača i ne prelaze 1500N. Prema rezultatima EMG aktivnosti muskulature odrazne noge moguće je zaključiti kako je priprema u smislu predaktivacije muskulature neposredno prije doskoka izuzetno važna kako bi se izveo dobar skok. Maksimalne vrijednosti EMG aktivnosti muskulature postizane su, najčešće u trenutku kontakta s podlogom. Analiziranim vježbama dubinskih skokova uspješno se može simulirati kretna struktura odraza koja se pojavljuje kod skoka u dalj iz zaleta, i jednako tako izazvati zadovoljavajuće opterećenje neuromuskularnog sustava. The goal of the research was to give a description and to standardize implementation procedures of the basic biomechanical techniques for simultaneous acquisition of kinematic, kinetic and EMG data on the drop jump exercises. Data collection was done by simultaneous employment of piezoelectric platform, used for measuring ground reaction force, an EMG device for measuring muscular activity and video signal acquisition, on the basis of which the kinematic analysis was later performed. Then the signals were used to interpreting and describing the drop jump exercises. Five top-quality long jumpers performed the drop jump exercises, which were frequently used in the technology of the athletics training. The EMG results of the take-off leg muscle activity indicated that the voluntary preparation in terms of muscle preactivation just prior to landing is crucial for a good jump performance. The maximum values of EMG activity were most frequently achieved in the very moment of establishing contact with the ground. The analysed biomechanical variables set high demands on the locomotor system of the examinees. The results indicated the high vertical ground reaction force at all levels, suggesting that the applied exercises generated loads equal to the long jump specific loads in actual performance (values of the vertical ground reaction force ranged from 3500 to 6300N). The obtained horizontal ground reaction force was expectedly lower (not exceeding 1500N) due to the lower horizontal speed of movement.

PREDIKCIJA REZULTATA KOD NESELEKCIONIRANE PLIVAČKE POPULACIJE TEMELJEM SPECIFIČNIH PLIVAČKIH TESTOVA PREDICTION OF RESULTS IN NON-SELECTED SWIMMERS BASED ON SPECIFIC SWIMMING TESTS Leko, Goran Grčić-Zubčević, Nada Sporiš, Goran plivanje; plivački ergometar; dinamometrija; Biokinetic swimming; swimming bench; dynamometry; tethered swimming; Biokinetic Primjena specifičnih plivačkih testova na suhom i u vodi zahtijeva dobro poznavanje tehnike plivanja od strane ispitanika. Cilj rada je bio ispitati da li na rezultate plivanja studentske populacije tj. ustanoviti mogu li se ti standardni plivački testovi (dinamometrija u vodi i plivački ergometar na suhom) mogu upotrijebiti za mjerenje neselekcionirane plivačke populacije. Uzorak ispitanika su činila 52 studenta, muškog spola, treće godine Kineziološkog fakulteta Sveučilišta u Zagrebu. Prediktorske varijable su predstavljali rezultati testiranja na plivačkom ergometru na suhom (Biokinetic swim bench) i to relativna snaga jednog i maksimalnog provlaka kraul tehnikom, 10 maksimalnih provlaka kraul tehnikom, jedna minuta na ergometru kraul tehnikom i dinamometrijska sila vuče u vodi. Kriterijske varijable su bili rezultati plivanja na 25, 50 300m kraul tehnikom i 50m dupin tehnikom. Analizirani su koeficijenti interkorelacija među svim varijablama. Nakon toga je regresijskom analizom utvrđivan utjecaj svih prediktorskih varijabli na svaku od kriterijskih. Jedino se test dinamometrije mjeren u vodi u mjestu (full-tethered swimming) pokazao kao uspješan prediktor rezultata na kraćim dionicama tj. 25 metara kraul, 50 metara kraul i 50 metara dupin. Na 300 metara kraul niti jedan prediktor se nije izdvojio kao značajan dok se kod dionice 50 metara dupin izdvoji i test dinamometrije 1 dupin provlak kao značajan. Zapaženo upućuje na zaključak da je test ergometrije na suhom potpuno neprimjeren za testiranje neselekcionirane plivačke populacije. SUMMARY In order to use specific swimming tests on land and in water the subjects must be well acquainted to swimming technique. The aim of this study was to investigate the possibility of usage of standard swimming test (full tethered swimming and swim bench tests on land) in non-selected swimming population. Fifty-two male subjects, students of the third year of the Faculty of Kinesiology, University of Zagreb underwent the testing procedure. The predictor variables were the results of measurements on Biokinetic swim bench (the relative power of one crawl pull; the relative power of 10 crawl pull; one minute crawl swimming; and the relative power of one maximal butterfly pull). The predictor variable measured in water was the maximal force produced during full-tethered swimming. The criteria were the results obtained at 25, 50 300m crawl and 50m butterfly swimming. The inter-correlations between all variables were calculated and regression analysis used in order to determine the influence of all four predictor variables on each criterion variable. Only the maximal force produced during full tethered swimming showed the significance in prediction of the results on shorter distances, 25m, 50m crawl and 50m butterfly swimming results. None of the tests showed any significance in prediction of 300m crawl swimming result. The test performed on swim bench out of water were not significant in prediction of the swimming results except for the test of one butterfly pull, which was related to the result on 50m butterfly swimming. In conclusion, the swimming bench is not a suitable method for evaluation and testing of non-selected swimmers probably because of their poor technique.

RELACIJE FUNKCIONALNIH SPOSOBNOSTI I NATJECATELJSKE USPJEŠNOSTI TENISAČA UZRASTA 12 DO 14 GODINA RELATIONSHIP BETWEEN FUNCTIONAL CAPACITY AND COMPETITIVE SUCCESSFULLNESS OF TENNIS PLAYERS COMPETING IN THE 12 TO 14 AGE CATEGORY Novak, Dario Tudor-Barbaros, Petar Matković, Bojan tenis; aerobni kapacitet; anaerobni kapacitet; spiroergometrija; natjecateljska uspješnost tennis; aerobic capacity; anaerobic capacity; competitive successfulness Cilj istraživanja jest utvrditi povezanost između pokazatelja funkcionalnih sposobnosti i natjecateljske uspješnosti tenisača i tenisačica u kategoriji natjecanja od 12-14 godina. Uzorak ispitanika čini 34 tenisača i 22 tenisačice u dobi od 12.3 do 14.9 godina koji se natječu u dobnoj kategoriji od 12 do 14 godina i rangirani su na rang listi Hrvatskog teniskog saveza. Povezanost između pokazatelja funkcionalnih sposobnosti i natjecateljske uspješnosti tenisača-ica utvrđena je Pearsonovim korelacijskim koeficijentom, a prediktivna vrijednost mjerenih parametara za procjenu natjecateljske uspješnosti uporabom regresijske analize. Rezultati ukazuju da postoji slaba, ali statistički značajna povezanost između parametara za procjenu aerobnog kapaciteta i natjecateljske uspješnosti u dječaka i djevojčica u dobnoj kategoriji 12-14 godina (p<.05). Također, postoji slaba, ali statistički značajna povezanost i između dobi i parametra za procjenu anaerobnog kapaciteta, i natjecateljske uspješnosti u dječaka u dobnoj kategoriji 12-14 godina (p<.05). The aim of the study was to investigate the relationship between indicators of functional capacities and the competitive successfulness of tennis players in the age category from 12 to 14 years. The sample of examinees consisted of 34 male and 22 female players from 12.3 to 14.9 years of age, competing in the age category from 12 to 14 years, that are ranked on the rank list of the Croatian tennis association. The relationship between measured parameters and competitive successfulness was established by the Pearson's correlation coefficient, and the predictive value of the parameters for estimating competitive successfulness by means of the regression analysis. The results showed a moderate, but statistically significant correlation between aerobic capacity parameters and competitive successfulness in boys and girls in the 12 to 14 age category (p<.05). In boys, there were also moderate, but statistically significant correlations between age, anaerobic capacity and competitive successfulness (p<.05).

USMJERAVANJE I IZBOR PRVOLIGAŠKIH ODBOJKAŠKIH IGRAČA U HRVATSKOJ CALL PROCESSING OF FIRST LEAUGE VOLLEYBALL PLAYERS IN CROATIA Marelić, Nenad Rešetar, Tomica Đurković, Tomislav usmjeravanje; izbor; prvoligaški odbojkaški igrači direction-supervision; selection; major volleyball players Osnovni ciljevi ovog istraživanja bili su utvrditi tko je najviše utjecao na igračevu odluku da se počne baviti odbojkom, utvrditi postoje li statistički značajne razlike između ženskih i muških ispitanika u odgovorima na postavljeno pitanje, te utvrditi utječe li dob ispitanika na rezultate istraživanja. Nadalje cilj je bio saznati dobnu strukturu pojedine ekipe i lige u cijelosti, te saznati u kojim su se mjestima igrači Prve A Hrvatske odbojkaške lige počeli baviti odbojkom. Ispitivanje je provedeno na svim ženskim i muškim prvoligaškim ekipama u Republici Hrvatskoj u prvom dijelu sezone 2004/2005 godine. Za deskripciju varijable dob korišteni su parametri aritmetička sredina, standardna devijacija, minimum, maksimum, raspon, standardna pogreška aritmetičke sredine i interval procjene aritmetičke sredine populacije. Statistička značajnost razlike između grupa ispitanika u odgovorima na pitanje 1. prema spolu utvrđena je hi-kvadrat testom. Na temelju rezultata utvrđeno je kako su prijatelji ispitanika najviše utjecali na njihovu odluku da se počnu baviti odbojkom. Analizirajući dobivene rezultate zaključeno je kako nema statistički značajne razlike između ženskih i muških ispitanika u odgovorima na postavljeno pitanje. The primary aims of this study were to establish facts, that are, are there according to statistics, significant differences in given answers between male and female examinee, also to confirm a fact about the age factor as an influential element on the results of the research. Also, the aim was to find out about the age structure of each team and league in general, and to learn about the places in which the volleyball players of the Major A Croatian volleyball league began to go in for this sport. The study was carried out among all male and female major league teams in the Republic of Croatia during the first half term of the season 2004/2005. The age variable is described through these following parameters: arithmetical mean, standard deviation, minimum, maximum, range, standard incorrectness of arithmetical mean and estimated time of the interval of arithmetic mean of the population. Statistically, the importance of the distinction between the answers of the examinee on to the first question, according to the age factor, was confirmed by the chi - square test. Information in tables and graphs demonstrate that people who influenced the most on the players decision to begin to go in for this kind of sport are basically their friends. The research has also shown that there are no statistic significant differences between male and female examinee in given answers.

POVEZANOST ANTROPOMETRIJSKIH KARAKTERISTIKA I MOTORIČKIH SPOSOBNOSTI KOŠARKAŠA U INVALIDSKIM KOLICIMA THE RELATIONSHIP BETWEEN ANTHROPOMETRIC INDICATORS AND MOTOR ABILITIES IN WHEELCHAIR BASKETBALL PLAYERS Ciliga, Dubravka Petrinović- Zekan, Lidija Trošt, Tatjana invalidska kolica; košarka u invalidskim kolicima; antropološke karakteristike; motoričke sposobnosti; invalidski sport sport for disabled; anthropometric characteristics; wheelchair basketball; motor abilities Vrhunski sport osoba s invaliditetom vrlo je zahtjevno područje istraživanja u smislu multidisciplinarnog pristupa. Cilj istraživanja je bio utvrditi veličinu i smjer relacija između izmjerenih motoričkih sposobnosti i antropometrijskih karakteristika. Izmjereno je šest testova bazične, tri testa specifične motorike, te šest antropometrijskih mjera. U istraživanju su bili obuhvaćeni sportaši (N=42) s tjelesnim invaliditetom, koji su uključeni u sustavni program treninga i natjecanja košarke u invalidskim kolicima. Podaci su obrađeni standardnim postupcima za utvrđivanje osnovnih deskriptivnih statističkih parametara. Relacije između varijabli za procjenu antropometrijskog statusa igrača i motoričkih testova testirane su pomoću kanoničke korelacijske analize. Visoki koeficijenti korelacija uočeni su među rezultatima u testovima koji mjere eksplozivnu snagu i koordinaciju. Primjenom kanoničke korelacijske analize utvrđen je samo jedan značajan faktor. Najbolje ga karakteriziraju mjere potkožnog masnog tkiva, mjere eksplozivne snage i agilnosti. Ovo je istraživanje potvrdilo da morfološke karakteristike utječu na manifestaciju nekih motoričkih sposobnosti. Vrijednost dobivenih rezultata sastoji se u tome da su oni prikupljeni sa osobama s invaliditetom odnosno kod specifične skupine košarkaša u invalidskim kolicima. Oni su vrlo rijetko predmet istraživanja, te će rezultati ovog istraživanja pridonijeti još boljem objašnjavanju različitih aspekata sporta osoba s invaliditetom. Elite sport of disabled persons is a very demanding research area in view of a multidisciplinary approach. The goal of the research was to determine the magnitude and the trend of the relations between the measured motor abilities and anthropometric characteristics. Six tests of basic motor abilities have been measured, as well as three tests of the specific motor abilities and six anthropometric dimensions. This research covers the athletes (N=42) with physical disability which have been integrated into a systematic programme of training and competition in the wheelchair basketball. The relations between variables for the evaluation of motor abilities and anthropometric characteristics of wheelchair basketball players were tested by means of the canonical correlation analysis. The standard descriptive procedures were used to obtain the standardization of results and their distribution. High correlation coefficients have been noticed among the results of the tests which measure explosive strength and co-ordination. By application of the canonical correlation analysis only one significant factor was determined, best characterized by measures of the body fat, the explosive strength and the agility. This research confirmed that morphologic characteristics affect some motor abilities. The results are valuable even more being collected from persons with disabilities, distinctive group of wheelchair basketball players. They are rarely object of research, so those results will contribute to better explanation of different aspects of sport for disabled persons.

"OSTEOCHONDRITIS DISSECANS" KOLJENSKOG ZGLOBA OSTEOCHONDRITIS DISSECANS OF THE KNEE Janković, Saša Tomac, Natalija koljeno; sport; osteohondritis disekans knee; sports; osteochondritis dissecans Osteohondritis disekans je bolest nepoznate etiologije osifikacijskog centra kondila bedrene kosti prilikom čega se dio zglobne površine omekša, i rascijepi sve do subhondralne kosti. Taj poremećaj je učestao za djecu u dobi od 8 do 14 godina, a rijetko se javlja u starijim dobnim skupinama. Čini se da su uzrok ove bolesti kombinacija dvaju faktora: 1) mehaničko opterećenje ili ozljeda nastala aktiv nošću i 2) podložnost (osjetljivost) bedrene kosti kao rezul tat nedovoljno zrele osifikacije u području bedre nog kondila. Važnost faktora ovisi o dobi. Čini se da je sportska trauma važnija u adolescenata i odraslih, dok je kod mlađe djece važniji defekt u osifikaciji bedrenog kondila. Dijagnoza osteochondritis dissecansa teško se postavlja zbog blagih simptoma u mlađih pacijanata, liječnik koji liječi mlađe sportaše uvijek mora razmišljati o toj bolesti u toj dobnoj skupini. Roditelji i treneri također moraju poznavati simptome te bolesti. In osteochondritis disekans, a poorly understood disorder of the femoral condyle ossification center, a portion of the joint surface softnes, shears, of separates through of the articular cartilage and underlying bone. This disorder is common, but not exclusive, in children age 8 -14 years; however, it is an infrequent problem in the adult. The disease appears to be caused by a combination of two factors: 1) mehanical shearing of injury from activity and 2) femoral condyle susceptibility (fragility) result ing from immature ossification of the femoral condyle. The importance of each factor depends on age. Athletic trauma seems more important in older children and adults, while in younger children, ossification defects render the femoral condyle more susceptible to minor repetitive injury. The diagnosis of juvenile osteochondritis of the knee can be elusive because of mild simptoms in many patiens presenting with this condition, physicans treating young athlets must be constantly aware of the prevalance of juvenile osteochondritis disecans in this group. Parents and coaches of these children must also acquire high awareness of the symptoms and signs. knee, sports, osteochondritis dissecans Croatian Olympic Committee 2006-07-04 text pdf http://hrcak.srce.hr/4422 http://hrcak.srce.hr/file/7232 Croatian Sports Medicine Journal (hsmv@kif.hr); Vol.21 No.1; ISSN 0354-0766 (Print) hr The full text of the papers published in this journal is intended for personal, professional and scientific use, as well as educational purposes, with regard to the authors and publishers rights.

TJELESNO OPTEREĆENJE I BRONHALNA REAKCIJA U ALERGIJSKOJ ASTMI (EIB) PHYSICAL LOAD AND EXERCISE-INDUCED BRONCHOSPASM Vidović, Gordan astma uzrokovana vježbanjem; bronhospazam uzrokovan vježbanjem; PEFR; spirometrija; test tjelesnog opterećenja exercise-induced asthma; exercise-induced bronchospasm; PEFR; spirometry; exercise tolerance test Tjelesno opterećenje se smatra nefarmakološkim, neimunološkim, dakle nespecifičnim bronhoprovokativnim stimulusom koji u većine oboljelih od astme izaziva bronhokonstrikciju. Malo je studija koje su ispitivale bronhalnu reakciju nakon testa tjelesnim opterećenjem u zdravih i rinitičara, kao i utjecaj nespecifične bronhalne reaktivnosti i preosjetljivosti dišne sluznice na veličinu te reakcije. Usprkos prihvaćenog stava da je konstantni protokol tjelesnim opterećenejm efikasniji od progresivnog u provokaciji bronhospazma, rijetka su istraživanja koja su izravno usporedila dva testa tjelesnim opterećenjem, a rezultati su kontroverzni. Exercise is a non-pharmacological, non-immunological, non-specific stimulus which causes bronchoconstriction in most asthmatic patients. Only a few studies have investigated bronchial reaction to exercise in normal and rhinitis subjects or the effect of non-specific bronchial reactivity and allergy on the intensity of bronchial reaction. Although the opinion that constant exercise stimulates bronchospasm more effectively than the incremental protocol has been widely accepted, few studies have directly compared the two exercise tests, and the results are controversial. .

POSEBNOSTI ODABIRA TJELESNE AKTIVNOSTI I POSEBNOSTI PREHRANE KOD DJECE S AUTIZMOM PARTICULARITY OF PHYSICAL ACTIVITY SELECTION AND DIET PARTICULARITY BY THE CHILDREN WITH AUTISM Blažević, Kruno Škrinjar, Jasminka Cvetko, Jasmina Ružić, Lana autizam; terapijski postupci; tjelesno vježbanje; prehrana; okolina. autism; therapy; procedure; physical activities; diet; enviroment. Autizam kao kompleksan i sveobuhvatan razvojni poremećaj predstavlja velik problem kako za samog autističnog pojedinca, tako i za okolinu koja nastoji pružiti odgovarajuću brigu i pronaći odgovor na niz problema koji se prije svega očituju u komunikaciji i odnosu s okolinom, stoga i u osobnom životu osobe s autizmom. Kao što se je razvijalo stajalište o nizu zdravstvenih činitelja koji imaju koristan utjecaj na sveobuhvatno stanje svake pojedine osobe u suvremenom društvu, tako je i u novije vrijeme poznato da određene aktivnosti i sadržaji dovode do značajnog napretka i poboljšanja u životu osobe s autizmom. Tjelesno vježbanje i prehrana čine značajan dio cjelokupnog terapijskog postupka u smanjenju i otklanjanju pojavljivanja simptoma autizma i pridonose kvalitetnijoj suradnji osobe s autizmom i okoline. Osobna obilježja i posebnosti poremećaja kod svakog pojedinca s autizmom vjerovatno su jedan od razloga što za sada nije razvijen jedinstveni pristup za rješavanje tog problema, te je poznavanje šireg raspona autističnog poremećaja i osnovnih terapijskih postupka potrebno da bi se dobila saznanja o tome kako pristupiti takvim osobama i pridobiti ih za suradnju. Autism is a complex developmental disorder and represents not only a deficiency to the individual with autism, but also a communication problem for his/her social environment. Usually, the social and family members extend their maximum efforts in order to overcome problems in interpersonal relationships and communications. Recently, the physical activity programs are being promoted because of the positive impact on the lives of people with autism. Physical exercise programs and a special diet as a vital part of the overall therapy procedure have been showed effectiveness in the treatment of autism since the manifestation of the autistic symptoms may be reduced or eliminated. That contributes to a more positive and healthier environment for the autistic individual. There is still no unique approach in the treatment of autism as disorders are diverse and vary from one individual to another. Therefore, the recognition of the tremendous diversity of autistic disorders is essential in the assessment and treatment of individuals with autism.

PREHRAMBENE NAVIKE I PREVALENCIJA PUŠENJA U SPORTAŠA EKIPNIH SPORTOVA DIETARY HABITS AND PREVALENCE OF SMOKING IN TEAM SPORTS ATHLETES Sorić, Maroje Mišigoj-Duraković, Marjeta Pedišić, Željko rukomet; košarka; odbojka; nutritivni unos; zdravstvene navike handball; basketball; volleyball; nutrient intake; health related habits Ovo istraživanje je poduzeto s ciljem opisivanja kvalitete prehrane i zdravstvenih navika sportaša i sportašica ekipnih sportova u Republici Hrvatskoj. Istraživanje je obuhvatilo ukupno 50 dvadesetogodišnjih sportaša (27 muškaraca i 23 žene) ekipnih sportova (košarka, rukomet, odbojka). Prehrambeni unosi su procijenjeni upitnikom za procjenu prehrambenih navika sastavljenim od općeg upitnika i upitnika frekvencija. Značajne razlike među spolovima su utvrđene kako za apsolutni unos energije (3209±1075 kcal/dan kod muškaraca i 2111±765 kcal/dan kod žena, p<0,001), tako i za relativni unos energije (40,0±12,8 vs. 32,2±10,5 kcal/kg/dan, p=0,02). Kod muškaraca su također utvrđeni i veći relativni unosi ugljikohidrata, masti i proteina, kao i svih minerala, ali ne i vitamina. Odstupanje prehrane ispitanika od preporuka se očituje u preniskom unosu ugljikohidrata kod oba spola (5,0±1,5 g/dan kod muškaraca i 4,2±1,3 g/dan kod žena) i u previsokom unosu kolesterola kod muškaraca (449±320 g/dan). Prevalencija pušenja cigareta je izrazito visoka u oba spola. Puši 33% sportaša i čak 39% sportašica. S druge strane, alkohol se konzumira znatno više među sportašima nego među sportašicama (73% vs. 39%, p=0,01). Iako je prehrana ispitanih sportaša u najvećem dijelu primjerena, potrebno je obratiti posebnu pozornost educiranju sportaša o nužnosti izbjegavanja duhanskih proizvoda i alkohola. U tome bi značajnu ulogu trebali imati treneri. The purpose of this study was to assess the quality of nutrition and health related habits of team athletes in Croatia. Fifty athletes (27 males and 23 females) were recruited for the purpose of this study. Dietary intake was assessed by the food frequency questionnaire. Significant differences between genders were detected for both absolute (3209±1075 kcal/day in men and 2111±765 kcal/day in women, p<0,001), and relative energy intakes (40,0±12,8 vs. 32,2±10,5 kcal/kg/day, p=0,02). Men athletes also had higher relative intakes of carbohydrates, fat, proteins and all minerals, while vitamin intakes were not different between groups. The intake of carbohydrates was slightly lower than recommended, 5,0±1,5 g/day in men and 4,2±1,3 g/day in women. Also, the intake of cholesterol was high in males, 449±320 g/day. The prevalence of smoking was very high, 33% in males and even 39% in females. On the other hand, there were more alcohol consumers in male than in female athletes (73% vs. 39%, p=0,01). In conclusion, although the overall nutrient intakes in our group of athletes appear to be adequate, special attention should be given to educating young athletes about the risks of alcohol and tobacco consumption. One of the leading roles in education should be given to team coaches.

BRONHOKONSTRIKCIJA U NAPORU TIJEKOM NATJECANJA U ORIJENTACIJSKOM TRČANJU EXERCISE-INDUCED BRONCHOSPASM DURING ORIENTEERING EVENT Nikolić, Bojana bronhospazam izazvan naporom; orijentacijsko trčanje exercise-induced bronchospasm; orienteering event Bronhospazam izazvan naporom(EIB) se često javlja u nekim se sportovima. Astma i atopija povećavaju rizik od EIB, te poleni, polutanti i druge štetne tvari u zraku. Cilj ovog istraživanja je bio utvrditi da li su kod natjecatelja u orijentacijskom trčanju prisutne značajne promjene u spirometrijskim funkcijama koje bi govorile za pojavu bronhospazma. Ispitivanje je provedeno za vrijeme natjecanja u orijentacijskom trčanju u disciplini klasika. Sudjelovala su 22 natjecatelja (5 žena, 17 muškaraca). Izmjerene su vrijednosti vršnog plućnog protoka (PEF) prije samog natjecanja i zagrijavanja, te u prvoj minuti po završetku natjecanja. Svaki ispitanik je ispunio upitnik o specifičnim simptomima. Kriterij za EIB (pad PEF nakon natjecanja više od 15% u odnosu na bazalnu vrijednost) zadovoljila su dva ispitanika. Jedan je naveo da je u djetinjstvu bolovao od astme, a drugi da povremeno tijekom natjecanja osjeća stezanje u prsima, sviranje u prsima ili nedostatak zraka. Niti jedan od ispitanika ne boluje od astme. Sedmero spominje alergiju u anamnezi. Na tri pitanja u upitniku za predikciju EIA, dva ispitanika su odgovorili pozitivno na prvo pitanje, troje na drugo, a svi odgovori na treće pitanje bili su negativni. Rezultati ukazuju da ne postoji statistički značajna razlika između bazalnih vrijednosti PEF i vrijednosti PEF izmjerenih nakon natjecanja (P<0.05). Tjelesni napor kojem su ispitanici bili izloženi nije imao značajan utjecaj na bronhoreaktivnost. Potrebna su daljnja ispitivanja pojave bronhokonstrikcije u naporu za vrijeme aktivnosti tijekom orijentacijskog trčanjanja prije nego se donesu definitivni zaključci. Exercise-induced bronchospasm (EIB) is more often in some sports. Risk from EIB is higher in asthmatics, as in atopic patients. Pollens and environmental pollutants can also contribute to development of EIB. The aim of this study was to explore whether this challenge can result in changes in spirometry that would be positive for bronchospasm in competitors during orienteering event. The study was conducted during orienteering event in classic distances. Twenty-two competitors participated in the study (5 women, 17 men). Peak expiratory flow (PEF) was measured before the event and warming up, and during first minute after crossing the finish line. Each participant completed a specific symptom questionnaire. Only two competitors reported PEF fall significant for EIB (fall PEF>15% after the event). One of them had asthma during childhood, and other sometimes during competitions feels chest pain, wheezing or shortness of breath. None of competitors had asthma. Seven mentioned allergies in anamnesis. All participants were asked three questions for EIB prediction; one answered positive on first question, three on second, and all answered on third question were negative. The results showed that statistical difference between basal PEF and PEF after event was not significant (P<0.05). Physical activity during orienteering event didn’t have significant influence on bronchoreactivity. Further researches of EIB during orienteering are needed before definitive conclusions.

MORFOLOŠKE PREDNOSTI I NEDOSTACI HRVATSKIH TENISAČA KATEGORIJE U-16 MORPHOLOGICAL ADVANTAGES AND DISADVANTAGES IN CROATIAN U-16 AND U-18 TENNIS PLAYERSI U-18 Čanaki, Martina Sporiš, Goran Leko, Goran TENIS; GRAĐA TIJELA, MORFOLOŠKE KARAKTERISTIKE; SOMATOTIPI tennis; body constitution; morphological characteristics; somatotype Glavni cilj ovog istraživanja bio je istražiti varijacije u građi tijela hrvatskih tenisača (dobnih kategorija do 16 Ii do 18 godina), te steći bolji uvid u prednosti i nedostatke morfoloških karakteristika. Morfološke razlike između dominantne i nedominantne ruke su također bile promatrane. U istraživanju je sudjelovalo četrdesetdevet vrhunskih hrvatskih tenisača juniora, dešnjaka. Uzorak je bio podijeljen u dvije grupe: igrači do 16 i igrači do 18 godina starosti. Upućeni međunarodnim biološkim programom, slijedeće antropometrijske varijable su bile izmjerene: visina tijela, tjelesna masa, dužina noge, dužina ruke, širina ramena i kukova, dijametar ručnog zgloba, lakta i koljena, opseg nadlaktice, opseg podlaktice, opseg grudi, opseg trbuha, te opseg natkoljenice i potkoljenice. Opseg nadlaktice se mjerio u pozicijama fleksije i ekstenzije. Somatotipi su izračunati korištenjem Heath-Carter-ovih jednadžbi. Razlike između dominantne i nedominantne ruke kod vrhunskih hrvatskih tenisača su analizirani u skladu s njihovom dobnom kategorijom koristeći t-test za značajne uzorke s statističkom značajnošću p<0.05. U skladu s njihovim građom tijela otkriveno je da su hrvatski tenisači dobnih kategorija do 16 i do 18 godina pretežno mezo-ektomorfi. Razlike između dominantne i nedominantne ruke (dužina ruke, dijametar ručnog zgloba i lakta, opsezi nadlaktice i podlaktice) su statistički značajne u obje testirane dobne grupe. Hrvatski tenisači dobnih skupina do 16 i do 18 godina su pretežno mezo-ektomorfi i postojanjem takvog somatotipa trebali bi stvoriti prednost u igri na mreži, te pored snažnih udaraca i sposobnost ostvarivanja velikih brzina udaraca. Također, trebaju manji broj koraka pri kretnju po na terenu. Kao što je očekivano, dugotrajno izlaganje stimulativnim podražajima treninga rezultat je većih opsega i dijametara kod dominantne ruke. Možemo zaključiti da, u vrhunskom tenisu, građa tijela ne stvara ograničenja pri maksimalnim dostignućima za veliku većinu testiranih igrača. The main purpose of the study was to explore variations in the body constitution of Croatian tennis players (age categories under 16 and under 18), and to gain a better insight into advantages and disadvantages originating from morphological characteristics. Morphological differences between the dominant and non-dominant arm were also analyzed. Forty-nine Croatian elite junior tennis players, all right-handed, participated in the study. The sample was divided into two groups: players under 16 and players under 18 years of age. As instructed by the International Biological Program, the following anthropometrical variables were measured: body height, body mass, leg length, arm length, biacromial and bicristal diameters, knee, elbow and wrist diameters, upper arm girth, forearm girth, chest girth, abdomen girth, thigh and calf girth. Upper arm girth was measured in the flexion and extension positions. Somatotypes were calculated using Heath-Carter equations. Differences between the dominant and non-dominant arm in elite Croatian tennis players were analyzed according to their age category using the Paired samples t-test and statistical significance was set at p<0.05. According to their body constitution, under 16 and under 18 year old Croatian tennis players were found to be predominantly meso-ectomorf. The differences between the dominant and non-dominant arms (arm length, elbow diameter, wrist diameter, upper and lower arm girth and forearm girth) were statistically significant in both tested age groups. As U16 and U18 Croatian tennis players are predominantly meso-ectomorf and being of that somatotype they should have an advantage while playing on the net, in addition to having powerful strokes and an ability to achieve high stroke speed. Also, they need a smaller number of steps when trying to position themselves in the desired spot on court. As expected, long-term exposure to training stimuli resulted in larger circumferences and diameters in the dominant arm. We can conclude that, in world class tennis, body constitution posses no limitations on maximal achievements for a vast majority of tested players.

ANTROPOLOŠKE KARAKTERISTIKE KAO OSNOVA ZA SELEKCIJUU ALPSKOM SKIJANJU ANTHROPOLOGICAL CHARACTERISTICS AS THE BASIS IN ALPINE SKIING SELECTION Cigrovski, Vjekoslav Matković, Bojan Krističević, Tomislav alpsko skijanje; antropološka obilježja; kategorija stariji dječaci alpine skiing; anthropological characteristics; category older boys Cilj ovog istraživanja bio je utvrditi povezanost morfoloških karakteristika i motoričkih sposobnosti s uspjehom u alpskom skijanju definiranom mjestom na rang listi Hrvatskog skijaškog saveza za kategoriju stariji dječaci u kalendarskoj godini istraživanja. Uzorak je bio sastavljen od 29 hrvatskih alpskih skijaša, testiranih u pripremnom periodu trenažnog ciklusa, prosječne dobi 13.94 godina. Mjereno je jedanaest morfoloških mjera, zatim jedan test za procjenu funkcionalne sposobnosti te četiri testa za procjenu eksplozivne snage. Regresijskom analizom utvrđena je mogućnost postojanja uzročno-posljedičnih odnosa između varijable ranga Hrvatskog skijaškog saveza i primijenjenih testova.. Nakon isključivanja niza varijabli utvrđeno je da je aerobni kapacitet ključan za uspjeh u alpskom skijanju u ovom uzrastu, a time i identifikaciji mladih talenata koji se tek uključuju u alpsko skijanje ili pak pri selekciji mladih sportaša prilikom prelaska u višu kategoriju, odnosno reprezentaciju. Navedeno će dodatno osigurati odabranom broju mladih skijaša kvalitetnije uvjete za trening i natjecanja te mogućnost postizanja vrhunskih sportskih rezultata u seniorskoj dobi. The aim of this research was to determine the relationship between some anthropometric characteristics and motoric abilities with the success in alpine skiing defined by the rank of the older boys in the Croatian Ski Federation for the examined year. Twenty-nine Croatian male alpine skiers were tested on 16 different variables including: eleven morphological parameters, maximal aerobic capacity and four tests to determine the motoric capabilities in the beginning of the season. The possible causative relationship between the success in alpine skiing was determined only for VO2 max. To conclude, aerobic capacity could contribute in the selection of important anthropological characteristics responsible for the success in alpine skiing and identification of young talented alpine skiers, as well as for the promotion of young skiers in the better category or their draft to national representation. The results of this research would also help to provide better training and competitive conditions for the selected young alpine skiers, which could finally lead to the better achievements in the senior age.

SPIROERGOMETRIJSKI PARAMETRI VRHUNSKIH NOGOMETAŠA SPIROERGOMETRIC PARAMETERS OF ELITE SOCCER PLAYERS Jerković, Stjepan Jerković, Marijan Sporiš, Goran nogomet; spiroergometrija; pozicije igrača soccer; spiroergometry; playing positions Cilj istraživanja bio je utvrditi centralne i disperzivne parametre nekoh morfoloških karakteristika i funkcionalnih pokazatelja 17 vrhunskih hrvatskih nogometaša. Sekundarni cilj ovog rada bio je utvrditi pozicijske razlike temeljem testiranih karakteristika i sposobnosti. Istraživanje je provedeno u Sportsko dijagnostičkom centru Kineziološkog fakulteta u Zagrebu. Utvrđena je statistički značajna razlika između igrača prema poziciji na kojoj igraju (MANOVA; Wilks' lambda=0.314, Raos'R=8,52, p<0.02). Vezni igrači imali su najveće vrijednosti VO2max dok su obrambeni igrači imali najveće vrijednosti primitka kisika pri anaerobnom pragu, a ujedno su bili najviši i najteži. Što se tiče ventilacijske funkcije pluća, najniže vrijednosti maksimalne frekvencije disanja imali su napadači i kao što se i očekivalo, nije bilo ograničenja postizanja maksimalnog opterećenja od strane ventilacijske funkcije pluća. Aerobni kapaciteti hrvatskih nogometaša su unutar raspona objavljenih rezultata vrhunskih svjetskih nogometaša, iako se vrijednosti aerobnog kapaciteta posebno za vezne igrače nalaze na donjoj granici preporučenih (59,92±3,14 mLkg min-1). Testirani vezni igrači trebali bi poboljšati svoje aerobne kapacitete, što bi moglo utjecati i na poboljšanje samog nastupa na utakmicama. The aim of the study was to determine the central and the dispersive parameters of some morphological characteristics and functional abilities in 17 elite Croatian soccer players tested by all-out VO2max treadmill test. Also, the present study investigated the differences in analyzed spiroergometric values in regard to the playing position. The research has been conducted in Sports diagnostic centre of the Faculty of Kinesiology in Zagreb. The differences between attackers, defenders and midfielders in analyzed parameters were determined (MANOVA results: Wilks' Lambda=0.314, Raos'R=8,52, p<0.02). Midfielders were the players with highest values of VO2max. Defenders had highest values of oxygen consumption at ventilatory threshold and were the tallest and the heaviest player in the team. The lowest values of maximal breathing frequency were found in attackers while the midfielders and the defenders had similar values. As expected, the ventilatory lung functions were satisfactory and did not represent the limit for maximal performance. In conclusion, aerobic abilities of Croatian soccer players are within reported values for international elite soccer player, but still in the lower range for midfielders (59,92±3,14 mLkg min-1). Therefore, Croatian soccer players, especially the midfielders should improve aerobic fitness, which might contribute to the overall better match performance Croatian Olympic Committee 2006-12-28 text pdf http://hrcak.srce.hr/8362 http://hrcak.srce.hr/file/12704 Croatian Sports Medicine Journal (hsmv@kif.hr); Vol.21 No.2; ISSN 0354-0766 (Print) en The full text of the papers published in this journal is intended for personal, professional and scientific use, as well as educational purposes, with regard to the authors and publishers rights.

PRIJELOM ZAMORA LATERALNE KUNEIFORMNE KOSTI: PRIKAZ SLUČAJA STRESS FRACTURE OF THE LATERAL CUNEIFORM: A CASE REPORT Janković, Saša Borić, Igor Bobić, Lana prijelom zamora; lateralna kuneiformna kost; nogomet stress fracture; lateral cuneiform bone; soccer U ovom stručnom radu opisuje se raznovrsna patogeneza prijeloma zamora s posebnim osvrtom na prijelome zamora kod sportaša i sportašica. Detaljno je prikazan slučaj prijeloma zamora lateralne kuneiformne kosti kod nogometašice, anamnestički podaci, klinička slika, radiološka obrada te terapijski postupci koji su nakon šest mjeseci doveli do povratka potpunoj aktivnosti. Prijelom zamora kuneiformne kosti su rijetki, slučaj prijeloma zamora lateralne kuneiformne kosti još nije opisan u literaturi. Prilikom postavljana diferencijalne dijagnoze boli u stopalu, bez traume ili abnormalnosti stopala u anamnezi, treba imati na umu i rijetku mogućnost postojanja prijeloma zamora lateralne kuneiformne kosti stopala. This paper deals with multilateral pathogenesis of the stress fractures. Special concern is given to the stress fractures in athletes. The case report presenting the stress fracture of the lateral cuneiform bone in a female soccer player is described. The details involving illness history, clinical symptoms, radiology data as well as therapy procedures are presented. The total recovery time was six months. The stress fractures of the cuneiform bone are rare and the stress fracture of the lateral cuneiform bone has not been previously reported in literature. The paper points to the fact that the attending physician should bare in mind the possibility of such type of injury while determining the diagnosis of pain in the foot, especially if no trauma or foot abnormalities exist in the patient history.

ORTOPEDSKI ULOŠCI U PREVENCIJI I LIJEČENJU SINDROMA PRENAPREZANJA NA STOPALU I GLEŽNJU PREVENTION AND TREATMENT OF OVERUSE INJURIES OF THE FOOT AND ANKLE BY ORTHOPAEDIC INSOLES Madarevic, Mladen Mirkovic, Maja Cicvara-Pecina, Tatjana Klobucar, Hrvoje Mahecic, Karolina Pecina, Marko Jelic, Miroslav stopalo i gležanj; sindromi prenaprezanja; liječenje; ortopedski ulošci foot and ankle; overuse injuries; treatment; orthopaedic insoles Sindromi prenaprezanja sustava za kretanje na donjim ekstremitetima,a osobito na stopalu su česta pojava u sportaša i predstavljaju dijagnostički i terapijski problem. Medu vanjskim čimbenicima uzroka nastanka sindroma prenaprezanja svakako su najznačajniji poremećaji biomehanike donjeg ekstremiteta i to opet prvenstveno poremećaj biomehanike samog stopala i njegove staticke i dinamicke funkcije. U korekciji poremećene biomehanike stopala najznačajnija je primjena odgovarajucih ortopedskih uložaka. Nakon provedene pedobarografske analize na elektronskoj platformi i to u stajanju i hodu pristupa se kompjuterskom dizajniranju individualnog ortopedskog uloška koji se potom izrađuje robotskom tehnikom od materijala različite tvrdoće. Ortopedskim uloškom korigiraju se sve registrirane deformacije u stražnjem,srednjem i/ili prednjem dijelu stopala, a ovisno o pojedinom sindromu prenaprezanja dodaju se i odredena povišenja, udubljenja odnosno rasterećenja stopala. Opisana je primjena ortopedskih uložaka u prevenciji i lijecenju sindroma prenaprezanja na stopalu, i to: plantarni fascitis, tendinitis dugog fleksora palca, tendinitis i entezitis prednjeg tibijalnog mišića, entezitis tetive kratkog peronealnog mišica, metatarzalgija, prednji sindrom sraza gornjeg nožnog zgloba,sindrom prenaprezanja Ahilove tetive, prijelom zamora metatarzalnih kostiju, prijelom zamora kosti tarzusa i sesamoiditis. Posebno se ukazuje na značaj primjene ortopedskih uložaka i u lijecenju ostalih sindroma prenaprezanja na donjem ekstremitetu kao što je patelarni tendinitis/tendinosis, sindrom trenja iliotibijalnog traktusa, itd. Zahvaljujući novoj tehnologiji u dijagnosticiranju statičkih i dinamičkih poremećaja stopala i novoj tehnologiji u izradi ortopedskih uložaka od različitih materijala moguće je danas prevenirati i liječiti mnogobrojne sindrome prenaprezanja u području stopala i cijelog donjeg ekstremiteta. Overuse injuries of locomotor system on lower limbs, especially those that are foot related, are common in athletes and are both diagnostic and therapeutic problem. The most important external factors causing the overuse injuries are biomechanic disorders of the lower limb, particularly foot related biomechanical disorders that have an impact on its static and dynamic function. The most important aspect of correcting the biomechanical disorders of the foot is application of orthopaedic insoles. Pedobarographic analysis made on electronic platform while standing and walking is followed by the computer assisted designing of individual orthopaedic insole made by robot machine using materials of different hardness. Orthopaedic insole corrects all the registered deformations in hindfoot, forefoot or/and midfoot and, depending upon particular overuse injury, heel elevations, cavities, or other types of unburdening are made. The application of orthopaedic insoles in plantar fasciitis, tendinitis of the flexor hallucis longus, tendinitis and synovitis of the tibialis anterior, enthesitis of the tibialis anterior, enthesitis of the peroneus brevis, metatarsalgia, anterior impigement syndrome of the ankle, overuse injury of the Achilles tendon, stress fracture of the metatarsal bones, stress fracture of the tarsal bones and sesamoiditis, is described. The significance of application of orthopaedic insoles in treatment of other overuse lower limb syndromes, such as patellar tendinitis/tendinosis and iliotibial band friction syndrome, is indicated.

MAKSIMALNI PRIMITAK KISIKA I BIOLOŠKA DOB KOD 12-GODIŠNJIH VESLAČA MAXIMAL OXYGEN UPTAKE AND MATURATION IN 12-YEAR-OLD MALE ROWERS Mikulić, Pavle Ružić, Lana Leko, Goran VO2max; biološka zrelost; mladi veslači; normalizacija rezultata VO2max; physical maturity; young rowers; allometric scaling Ova studija provedena je sa ciljem ispitivanja razlika u maksimalnom primitku kisika (VO2 max) izmedu 47 veslaca iste kronološke dobi (12-godišnjaci, AS±SD = 12,5±0,3), ali različite biološke dobi. VO2 max je izražen u apsolutnim jedinicama (L/min), u omjeru prema tjelesnoj masi (mL/kg/min) kao i uz upotrebu nelinearnog modela specifičnog za uzorak ispitanika. Biološka zrelost procjenjivana je vizualno korištenjem klasifikacije faza spolne zrelosti prema Tanneru. Ispitanici-veslači podijeljeni su u grupu veslača u pred-pubertetu (faza 1 po Tanneru), ranom pubertetu (faza 2 po Tanneru) i srednjem pubertetu (faze 3 i 4 po Tanneru). Mladi veslači podvrgnuti su progresivnom maksimalnom testu opterecenja na pokretnom sagu, a razlike su uspoređene upotrebom ANOVE. VO2 max (L/min) u 12-godišnjih veslaca pokazao se većim u veslača u srednjem pubertetu u odnosu i na one u ranom pubertetu (+19,7%), i posebno na one u predpubertetu (+24,8%). Izražen u odnosu na tjelesnu masu (mL/kg/min), VO2 max je bio +12,1% veci u veslaca u srednjem i pred-pubertetu u odnosu na one u ranom pubertetu. Međutim, kada su rezultati usporedeni upotrebom adekvatnog postupka normalizacije rezultata, VO2 max u veslača u srednjem pubertetu bio je +14.5% veci u odnosu na one u ranom pubertetu i +9,1% veci u odnosu na one u pred-pubertetu. Takvi rezultati sugeriraju da neki drugi čimbenici pored veće tjelesne mase objašnjavaju veću aerobnu snagu (procijenjenu sa VO2 max) kod biološki starijih pojedinaca iste kronološke dobi. Upotreba nelinearnog modela za pokazatelj VO2 max u ovoj studiji ukazala je na koeficijent skaliranja (eksponent) za tjelesnu masu 0,68 (95% CI = 0,51-0,87). Ovo otkriće pojačava pretpostavku da se, kod djece, VO2 max povecava u odnosu na tjelesnu masu sa eksponentom 0,67, a ne u direktnom odnosu sa tjelesnom masom (tj. masa 1,0). Zaključno, korištenjem nelinearnog modela u svrhu adekvatne kontrole tjelesne mase dokazali smo značajne razlike u VO2 max izmedu 12-godišnjih veslaca razlicitih po biološkoj dobi. Daljnja istraživanja su neophodna u svrhu detaljnijeg objašnjenja gore spomenutih razlika između grupa veslača razlicite biološke dobi neovisno o tjelesnoj masi. This study was designed to examine the differences in VO max between 47 rowers of the same chronological 2 age (12-year-olds; mean ± SD 12,5 ± 0,3), but of varying levels of physical maturity. VO max was expressed in 2 absolute units (L/min), as the ratio standard mass-related units (mL/kg/min) and using the allometric model specific to the data set. Sexual maturity was visually assessed using indices of pubic hair developed by Tanner. The subjects were classified in pre-pubertal (Tanner stage 1), early-pubertal (Tanner stage 2), and mid-pubertal (Tanner stages 3 and 4) groups. They completed an incremental maximal treadmill test. Differences were compared using a one-way ANOVA. VO max (L/min) in 12-year-old rowers proved to be 2 greater in the mid-pubertal group than in both the earlypubertal (+19,7%) and pre-pubertal (+24,8%) groups. When expressed as a ratio standard (i.e. in mL/kg/min), VO max was +12,1% greater in the mid- and pre- 2 pubertals than in the earlypubertals. However, when compared using the appropriate scaling procedure, the VO max in mid-pubertal rowers was +14.5% greater than 2 in the early-pubertals, and +9,1% greater than in prepubertals. This suggests that factors other than body mass explain the greater aerobic power (as assessed by VO max) in more physically mature individuals of the 2 same chronological age. Allometric scaling of VO max in 2 the present study yielded a scaling coefficient for body mass of 0,68 (95% CI = 0,51-0,87). This finding reinforces the view that, in children, VO max increases 2 relative to body mass raised to the power of 0,67 rather than in direct proportion with body mass (i.e. mass1,0). In conclusion, using a log-linear scaling model to adequately control for body mass, we have demonstrated significant differences in VO max among 12-year-old 2 rowers of varying stages of puberty and, consequently, varying levels of maturity. Further research is needed in order to further explain the above-mentioned differences among groups of rowers exhibiting differing levels of maturity independent of body mass.

ELEKTROMIOGRAFSKA AKTIVNOST MUSKULATURE NOGU PRI IZVODENJU OSNOVNOG KORAKA NA RAZLIČITIM VISINAMA STEP KLUPICE ELECTROMYOGRAPHIC ACTIVITIES OF LEG MUSCLES WHEN PERFORMING BASIC STEP AT DIFFERENT HEIGHTS OF THE STEP BENCH Horvatin-Fuckar, Maja Medved, Vladimir Kasovic, Mario elektromiografija (EMG); muskulatura donjih ekstremiteta; step aerobika electromyography (EMG); muscles of lower extremities; step aerobics Utvrditi opterećenost muskulature donjih ekstremiteta tijekom dinamičkih kontrakcija penjanja i spuštanja na step klupicu pri izvođenju osnovnog (basic step) koraka na različitim visinama step klupice (15.2 cm, 20.3 i 25.4 cm) bio je cilj ovog istraživanja. 8-kanalni (TELEMG) sustav za mjerenje EMG signala omogućio je istovremeno praćenje, osam karakteristicnih mišica nogu: m. rectus femoris, m. biceps (caput longum), m. gastrocnemius medialis, m. gluteus maximus, desne i lijeve noge, za ciju se aktivnost može sa sigurnošću reci da su pri izvodenju step koraka znacajni. Mjerenjem je bilo obuhvaceno 9 ispitanika, dugogodišnjih profesionalnih voditelja step aerobike. Analizom osnovnih statističkih parametara promatranih mišica izračunatih iz obrađenih EMG signala, vidljivo je da je ukupni utrošak energije desne noge, tzv. vodeće noge, očekivano najveći. Najveći utrošak imao je m. biceps femoris; zatim m. gastrocnemius medialis, m. gluteus maximus, te m. rectus femoris. Wilcoxon-ov test ekvivalentnih parova je dokazao da postoje ocekivano statisticki značajne razlike u intenzitetu mišićne kontrakcije povećanjem intenziteta opterećenja s povišenjem step klupice. The main goal of this research was to establish the exertion of lower extremities' muscles during dynamic contractions of stepping up and down the step bench when performing the basic step at different heights of the step bench (6, 8 and 10 inches). The 8-channel measuring system (TELEMG) for measuring EMG signals enabled the monitoring of eight characteristic muscles of both right and left leg: m. rectus femoris, m. biceps (caput longum), m. gastrocnemius medialis, and m. gluteus maximus, whose activities are significant while performing the step aerobic steps. The measuring procedures included 9 examinees, long-term professional step aerobics trainers. By analyzing the basic statistics parameters of the monitored muscles calculated from the processed EMG signals, it is evident that the total energy consumption of the right leg, so-called the leading leg, is the greatest. The biggest consumption was in m. biceps femoris; then m. gastrocnemius medialis, m. gluteus maximus, and finally in m. rectus femoris. The Wilcoxon matched pairs test has proved that there are statistically significant differences in muscle contraction intensity when increasing the exertion intensity by increasing the height of the step bench.

UTJECAJ PROGRAMIRANOG DEVETOMJESEČNOG TRENINGA KARATEA NA PROMJENE MOTORIČKIH OBILJEŽJA DJEČAKA OD 9 DO 11 GODINA THE INFLUENCE OF NINE MONTH KARATE TRAINING ON CHANGES OF MOTOR ABILITIES IN NINE AND TEN-YEAR OLD CHILDREN KARATEKAS Vidranski, Tihomir Sertić, Hrvoje Segedi, Ivan karate; motorčke sposobnost; dječaci; agilnost; programirani trening karate; motor abilities; boys; agility; programmed training Osnovni cilj rada bio je utvrditi dolazi li i u kojoj mjeri do promjene motoričkog statusa dječaka pod utjecajem treninga karatea te postoje li razlike u promjeni i razvoju razlicitih motoričkih sposobnosti pod utjecajem devetomjesecnog treninga karatea izmedu eksperimentalne grupe A (9-10 g.) i B (10-11 g.). Uzorak ispitanika cinili su dječaci karataši, učenici osnovnih škola, koji su u trenutku inicijalnog testiranja imali od 9 do 10 godina, i od 10 do 11 godina. Obje grupe podvrgnute su istom devetomjesečnom programiranom karate tretmanu koji je zajedno sa redovitom nastavom tjelesne i zdravstvene kulture utjecao na motorički status djece. Uzorak varijabli činilo je 12 varijabli za procjenu bazicnih i specifičnih motoričkih sposobnosti. U skladu sa postavljenim ciljevima ovoga rada, rezultati istraživanja potvrduju prvu postavljenu hipotezu da pojacana kineziološka aktivnost u vidu treninga karatea utjece na kvalitativne i kvantitativne promjene motoričkog statusa djece karataša. Takoder je potvrdena i druga hipoteza da postoje razlike u promjeni i razvoju razlicitih motoričkih sposobnosti (brzine frekvencije pokreta, eksplozivne snage tipa skoka i bacanja) pod utjecajem devetomjesečnog treninga karatea izmedu eksperimentalne grupe A (9-10 g.) i B (10-11 g.). U latentnom prostoru na temelju dobivenih rezultata može se zaključiti da je devetomjesecni programirani karate trening prouzročio pozitivne promjene motoričkih sposobnosti deveto- i desetogodišnje djece karataša. The basic aim of this study was to determine whether and to what extent do changes in motor status occur under the influence of karate training, and whether there are differences in changes and development of various motor abilities under the influence of a nine-month karate training between the experimental A group (9-10 years of age) and the control B group (10-11 years of age). The sample was comprised of male karatekas, the elementary school students who, at the time of the initial testing, were 9-10 and 10-11 years old. Both age groups were exposed to the same nine-month programmed karate training which affected, together with their regular PE classes, the motor status of children. Twelve variables were used in order to assess the basic and specific motor abilities. In accordance with the aim of the study, the results confirmed the first hypothesis stating that the increased level of physical activity karate training in this case affects both the qualitative and the quantitative changes in the motor status of children-karatekas. The second hypothesis, stating that there were differences in changes and development of various motor abilities (e.g. frequency of movements, explosive jumping and throwing strength) under the influence of a nine-month karate training between the A and B group, was also confirmed. On the basis of obtained results, it can be concluded that, with regard to the latent sphere, the nine-month karate training caused positive changes of motor abilities in nine- and ten-year-old children-karatekas.

INTERPERSONALNI ODNOSI KADETSKE ODBOJKAŠKE REPREZENTACIJE PRIJE I NAKON NATJECANJA INTERPERSONAL RELATIONSHIPS OF NATIONAL YOUTH VOLLEYBALL TEAM BEFORE AND AFTER THE COMPETITION Marelić, Nenad Đurković, Tomislav Rešetar, Tomica odbojka; interpersonalni odnosi volleyball, interpersonal relationships Poznavanje sociološke strukture malih grupa kao što je slučaj u sportu, može imati značajan utjecaj na konačni rezultat, stoga je poznavanje iste bitan faktor uspjeha. U sklopu kadetskog odbojkaškog europskog prvenstava provedeno je istraživanje temeljem sociometrijskog mjerenja. Ispitanici su odgovarali na modificirani Morenov test emocionalnog, funkcionalnog i funkcionalno-upravljačkog karaktera i to prije i nakon prvenstva. Svako od postavljenih pitanja predstavljala su zasebne varijable. Izrađena je deskriptivna statistika interpersonalnih privlačenja, odnosno odbijanja. T-testom pokušalo se utvrditi da li postoje statistički značajne razlike izmedu inicijalnog i finalnog stanja unutar svake od varijabli. Klaster analizom pokušala se utvrditi homogenost skupina ispitanika. Rezultati su pokazali da se grupa dijeli u dvije subgrupe, medu kojom se ističu kapetan ekipe i najbolji igrač reprezentacije. Nadalje t-test pokazao je statistički značajne razlike u mjerenjima izvršenim prije i nakon europskog prvenstva u varijabli funkcionalno-upravljačkog tipa (Koje igrače smatraš sposobnima da budu predstavnici ekipe na sastancima Odbojkaškog saveza Hrvatske?). Taksonomija je pokazala promjene u analiziranim subgrupama. Spajanje klastera u sve veće klastere rezultiralo je uvidom u hijerarhijsko stablo, koje je pokazalo različiti status kapetana ekipe u inicijalnom i finalnom mjerenju. Micro social structure of one group of players that form a team can strongly influence the final score. During Youth Volleyball European Championship 2003 the research was conducted based on a sociometric questionnaire. Players were given a modified Moreno test before and after the championship. Each question represented one independent variable. Descriptive statistic was performed based on the interpersonal relationship. T test was used to inspect possible statistical significance between initial and final results in every variable. Homogeneity of groups was tested using the Cluster analysis. Results indicated that the team is divided in two subgroups with two distinguished players the team captain and the team's best player. T test results of affirmed statistical significance between results of the first and the second measurement in variable which represent functional operating status (Which players are capable to represent your team during National federation meetings?).Taxonomy affirmed changes in analyzed subgroups. Cluster tree showed different status of the captain of the team in initial and final measurements.

BIOMEHANIČKA ANALIZA LJUDSKOG KRETANJA U FUNKCIJI SPORTSKE TRAUMATOLOGIJE BIOMECHANICAL ANALYSIS OF HUMAN MOVEMENT IN THE FUNCTION OF SPORTS TRAUMATOLOGY Medved, Vladimir Kasović, Mario biomehanika; analiza hoda; sportska traumatologija; koljenski zglob biomechanics; gait analysis; sports traumatology; knee joint Moderni pristup dijagnostici ljudskog kretanja, za potrebe medicinskih, kao i raznih sportskih primjena, bazira se na laboratorijskim biomehaničkim mjerenjima i analizama. Eksperimentalni podaci obuhvaćaju prostorne kinematičke veličine, silu reakcije podloge i višekanalnu površinsku elektromiografiju (EMG). Inverznim dinamičkim pristupom ostvaruje se matematička procjena unutarnjih sila i momenata sila u zamišljenim središtima zglobova. Prikazan je postupak u okviru suvremeno opremljenog laboratorija na Kineziološkom fakultetu gdje se mogu mjeriti i biomehanički analizirati različite kretne strukture. Postupak je ilustriran primjerom iz sportske traumatologije gdje je u prvom redu namjera procijeniti funkciju koljenskog zgloba u cilju poboljšane dijagnostike i liječenja. Tu kombiniramo mjerenja hoda sa specifično dizajniranim testovima. Opisani pristup (uz nedostatak još nekih metoda kao što su, u prvom redu, mjerenje potrošnje kisika i pedobarografija) predstavlja „state-of-the-art“ metodologiju analize ljudskog kretanja za čije je učinkovito korištenje bitna inter-disciplinarna suradnja liječnika specijalista sa biomehaničarima: kineziolozima i tehničkim stručnjacima. Modern approach to human movement diagnostics, for both medical as well as for various sportive application purposes, resides on laboratory biomechanical measurements and analyses. Experimental data encompass spatial kinematic variables, ground reaction force, and multi-channel surface electromyography (EMG). Through inverse dynamic approach mathematical estimation of internal forces and moments in virtual joint centres is accomplished. A procedure is presented in realms of a modern equipped laboratory facility at the Faculty of Kinesiology, where various movement patterns may be measured and analysed biomechanically. An example from the area of sports traumatology is taken for illustration. The aim was to evaluate the function of the knee joint as well as to improve the diagnostic and treatment procedures. Measurement of gait, in addition to certain specifically designed tests, was used. The approach described (lacking some methods such as the oxygen consumption measurement and pedobarography) represents a „state-of-the-art“ methodology in the area of human movement analysis. For its efficient use, it is essential for inter-disciplinary collaboration to take place, primarily collaboration between medical specialists, biomechanicians, kinesiologists and technical experts.

20 GODINA NAKON REKONSTRUKCIJE STRAŽNJE UKRIŽENE SVEZE UMJETNIM LIGAMENTOM GORE-TEX: PRIKAZ SLUČAJA 20 YEARS FOLLOW-UP OF GORE-TEX POSTERIOR CRUCIATE LIGAMENT RECONSTRUCTION Smoljanović, Tomislav Ivković, Alan Borić, Igor Seiwert, Sven Hašpl, Miroslav Pećina, Marko Gore-Tex; rekonstrukcija; stražnja ukrižena sveza Gore-Tex; reconstruction; PCL Prije dvadesetak godina u Klinici za ortopediju ugrađivali smo umjetne ligamente, i to tip proteze ligamenta Gore-Tex (razgranati polytetrafluoroethylen) kao postupak spašavanja nestabilnih koljena. U 13 bolesnika koristili smo protezu ligamenta Gore-Tex za rekonstrukciju stražnje ukrižene sveze (engl. posterior cruciate ligament PCL). U pacijenta F. K. imali smo priliku nakon 20 godina od izvršene rekonstrukcije PCL-a izvršiti kliničku, artroskopsku, magnetskorezonantsku (MRI) i patohistološku evaluaciju. Zbog artrotskih promjena u koljenu u bolesnika je bilo potrebno izvršiti artroskopsku toaletu koljena. Tom prilikom se izvršila i artroskopska evaluacija ugradene proteze ligamenta Gore-Tex te se napravila biopsija za patohistološku analizu (PHD). Prethodno je napravljen MRI koji je pokazivao uredan kontinuitet i volumen PCLa uz uznapredovale artrotske promjene koljena. Nalaz MRI bio je sukladan kliničkom nalazu koji je pokazivao dobru stabilnost koljena. Tijekom artroskopije uz standardne ulaze koristio se i posteromedijalni ulaz radi boljeg prikazivanja PCL-a. Artroskopija je pokazala da je proteza ligamenta Gore-Tex u cijelosti obložena zadebljanom sinovijalnom membranom odnosno fibrozom, a kada se na jednom mjestu odstranila sinovijalna membrana vidjele su se karakteristične polytetrafluoroethylenske niti u kontinuitetu. Probatornom sondom dokazao se kontinuitet PCL-a, a potom se uzelo nekoliko komadića ovojnice umjetnog ligamenta za PHD. Isto tako uzelo se i nekoliko komadića sinovijalne membrane iz drugih dijelova koljena. Patohistološki nalaz je pokazao da nema upalne reakcije u sinovijalnoj membrani koljena, a u ovojnici proteze ligamenta Gore-Tex našlo se zrelo vezivno tkivo s prisustvom multinuklearnih orijaških stanica uz fragmente stranog polarizirajuceg materijala. Ovaj prikaz slučaja pokazuje dobru biokompaktibilnost te dobru stabilnost koljena nakon 20 godina od ugradnje proteze ligamenta Gore-Tex u bolesnika s izrazito nestabilnim koljenom. Zanimljivo je napomenuti da nije došlo do propadanja niti polytetrafluoroethylena. Twenty years ago the Gore-Tex expanded polytetrafluoroethylene (PTFE) prosthetic ligament was used as feasible salvage procedure in patients with failed, multiply operated knees, or knees with gross instability. At the Department of Orthopaedic Surgery we operated 13 patients and replaced the posterior cruciate ligament (PCL) with the Gore-Tex prosthetic ligament. Recently we had opportunity to evaluate clinical, arthroscopic, magnetic resonance imagining (MRI) and patohystologic (PH) findings in patient F. K. twenty years after the reconstruction. Due to osteoarthritic changes arthroscopic toilette of the knee was performed. On that occasion arthroscopic evaluation and biopsies for microscopic examination were carried out. MRI performed prior to arthroscopy revealed tidy continuity and volume of PCL with advanced arthritic changes of knee. MRI findings were consistent to clinical findings of good knee stability. Arthroscopy revealed the Gore-Tex prosthetic ligament completely coated with thicken synovial membrane i.e. fibrosis. Partial removal of the synovial membrane showed continuity of characteristic PTFE strands. The continuity of PCL was established by the probe. After that, few pieces of synovial membrane from sheath of PCL and from other parts of synovial membrane of the knee were taken. One PTFP strand of artificial PCL was collected as well. Patohystological findings clearly excluded inflammatory reaction in synovial membrane of the knee. Furthermore, synovial membrane of Gore-Tex prosthetic ligament sheath was found to contain mature fibrotic tissue with multinuclear giant cells and fragments of foreign polarizing material. This case report demonstrated good biocompatibility and good knee stability twenty years after replacement of the PCL with the Gore-Tex prosthetic ligament in patient with gross instability. It is interesting to mention that there was no deterioration of PTFE strands.

STRUCNI SEMINAR HUZDUK Vidović, Ivo SEMINAR; HUZDUK Ovogodišnji strucni skup Hrvatske udruge zdravstvenih djelatnika u košarci održan je u Vodicama, sredinom mjeseca lipnja. Kao što je poznato, to je ujedno i obaveza prisustvovanja za sve one zdravstvene djelatnike koji djeluju u košarkaškom sportu, a na osnovu cega se dobivaju licence za narednu natjecateljsku sezonu. Naše okupljanje i strucni sastanci godinama postižu svoj cilj. Osim što je to mjesto druženja i razmjene iskustava, program i odabir teme nanovo pobuduje zainteresiranost i aktivno ucešce sudionika. Naša udruga otvorena je za sve zdravstvene djelatnike u športu uopce, pa smo i ove godine uputili pozive svim savezima na ucešce u seminaru. I sam odabir tema , kao i predavaca, sugerira da želimo postici jednu sveobuhvatnost u zdravstvenoj problematici svih športova, odnosno njihovih pripadnika. U gotovo trodnevnom radu zapoceli smo rad izlaganjem našeg nekadašnjeg fizioterapeuta D. Butala o „Doprinosu fizioterapeuta u svjetskim dostignucima hrvatskog alpskog skijanja“ što je poduprto sa zgodnim usporedbama. Jasno da je to izazvalo i bogatu raspravu. U subotnjem programu iznesene su teme o pregledu kardiovaskularnog sustava u ambulanti športske medicine te njegovi problemi u športskim aktivnostima što su predavali kolege Bošnjak i Gjurovic. Dosta rijetko obradivane probleme o dijabetesu u športu iznio je kolega Koršic, inace glavni lijecnik hrvatske hokejske reprezentacije. Veliku pozornost izazvala je tema o prakticnim postupcima u zbrinjavanju hitnih stanja športaša na terenu, predavana od kolege Tripkovica. Kašnjenje vec u prijepodnevnom programu bio je samo dokaz široke diskusije i brojnih pitanja, što nas je, ustvari, obradovalo. Posebnu pozornost izazvalo je izlaganje u radionici o novostima u bandažama i njihovom prakticnom prikazu, što je demonstrirao predstavnik njemacke tvrtke „Mueller“, dajuci našem skupu i medunarodni karakter. Sljedeci dan bio je predviden za prikaze i radionice o „Sakroilijakalnom zglobu od anatomije do manualne repozicije“ te „Cross fiction masaži športaša“.Sve je radeno po grupama kako bi ucesnici isprobali vježbe raznih manualnih tehnika.To su uspješno vodili kolega Stošic i viši fizioterapeut Mistura. Na kraju veliko nam je zadovoljstvo što je kod ucesnika, kako lijecnika tako i fizioterapeuta, zamijecen pretežan broj mladih pa nam to daje dodatne motive za uspješnost u buducnosti. Po obicaju seminar je završen završnom rijecju predsjednika HUZDUK-a uz podjelu potvrdnica. Ovom seminaru je prisustvovao 61 polaznik medu kojima 3 predstavnika drugih športskih saveza. Ovom prigodom održana je i godišnja izvještajna skupština HUZDUK-a.

KRATKI IZVJEŠTAJ O ORGANIZACIJI „10TH ANNIVERSARY ITTF SPORTS SCIENCE CONGRESS“ Kondrič, Miran ITTF; stolni tenis, kongres U Zagrebu od 18. do 20. svibnja ove godine održan je 10. znanstveni kongres Medunarodne stolnoteniske federacije u organizaciji Medunarodne stolnoteniske federacije, Hrvatskog stolnoteniskog saveza i Kineziološkog fakulteta iz Zagreba. Na kongresu je ucestvovalo 76 znanstvenika iz 27 zemalja širom svijeta. Stolni tenis jedan je od pet najraširenijih sportova na svijetu, ali i jedna od najpopularnijih igara s lopticom i reketom za sve životne kategorije. Ta igra omogucuje da se njome, na svoj nacin, bave svi bez obzira na dob i sposobnost. Posebno je preporucljiva zbog male mogucnosti ozljedivanja. Mala mogucnost ozljedivanja i relativno nisko opterecenje uvrštavaju ovaj sport u rekreativne aktivnosti s naglaskom na dobru prevenciju od ozljeda, s karakteristikama kratkih pokreta nižeg intenziteta. Kao pogodan oblik rekreacije starijih osoba i nekih vrsta rehabilitacije preporucuju ga mnogi lijecnici, fizioterapeuti i kineziolozi. Zbog svega toga, stolni tenis je idealan sport za korisno i zdravo upotpunjavanje slobodnog vremena. No slika je malo drukcija u natjecateljskom stolnom tenisu. Zbog izrazito brze igre dolazi do brzih kratkih pokreta, koji se obicno završavaju sa brzim zaustavljanjem pokreta. Opterecenje ramenog pojasa i opterecenje donjih ekstremiteta tako predstavljaju najizloženiji dio tijela u stolnoteniskoj igri. Znanstvenici širom svijeta zato sve više vremena posvecuju istraživanjima opterecenja stolnotenisaca u samoj igri i adaptaciji tijela na sve vece napore. Zato ne cudi ni cinjenica, da je na kongresu sudjelovao tako veliki broj znanstvenika. Veliki broj primljenih sažetaka recenzirali su clanovi znanstvenog odbora (Miran Kondric, Slovenija; Jean Francois Kahn, Francuska; Yutaka Tsuji, Japan; Michael Scott, USA; Hung Tsung Min, Tajvan; Gordana Furjan Mandic, Hrvatska; Branka Matkovic, Hrvatska; Vladimir Medved, Hrvatska; Igor Jukic, Hrvatska; Damir Sekulic, Hrvatska). Autori su prijavili 80 radova izmedu kojih je bilo 37 uvrštenih u usmeno izlaganje a preostali u poster sekciju. Na žalost zbog prekratkog termina trajanja kongresa nismo uspjeli omoguciti svim sudionicima usmeno izlaganje. Cetvorica pozvanih predavaca (Yutaka Tsuji, Japan; Damir Hudetz, Hrvatska; Matej Tušak, Slovenija; Jean Francois Kahn, Francuska) otvarala je pojedine sekcije na temu materijala u stolnom tenisu, prevencije i ozljede, psihološke pripreme stolnotenisaca i potpore trenažnom procesu. Predstavljeni radovi u svim sekcijama znacajni su prije svega za vodece u Medunarodnoj stolnoteniskoj federaciji (ITTF). Stolni tenis naime treba promjene, koje bi igru približile gledaocima kako u dvorani tako i pred TV ekranima. Današnja igra prebrza je a ITTF suocava se i sa zahtjevima Medunarodnog olimpijskog komiteta, koji traži zabranu ljepljenja reketa i upotrebu ljepila koje sadržava štetne sastojke. Odluke koje ce biti donesene u slijedecem razdoblju sigurno ce biti uvjetovane i rezultatima radova, koji su bili prezentirani na tom kongresu. Isto tako ITTF ce sigurno predložiti pojedinim nacionalnim savezima uvažavanje novih znanstvenih spoznaja, koja utjecu prije svega na poboljšanje zdravlja stolnotenisaca i na prevenciju ozljeda, koje su od uvodenja vece loptice sve cešce. Rezultati odnosno referati prezentirani na kongresu nisu dostupni samo ITTF i sudionicima kongresa. Na kongresu je bio izdan zbornik sažetaka u tiskanom i digitalnom obliku, a u srpnju 2007 bit ce svim sudionicima poslan i zbornik radova isto tako u tiskanom i digitalnom obliku.

UTJECAJ TJELESNE AKTIVNOSTI NA NEKE ODREDNICE ZDRAVSTVENOG FITNESA DJECE I OSOBA S CEREBRALNOM PARALIZOM THE INFLUENCE OF PHYSICAL ACTIVITY ON VARIOUS DETERMINANTS OF HEALTH-RELATED FITNESS IN CHILDREN AND ADULTS WITH CEREBRAL PALSY Klaić, Irena Milaščević, Darko cerebralna paraliza; fitnes; rast; jakost; ravnoteža cerebral palsy; fitness; growth; strength; balance Cerebralna paraliza je termin koji označava skupinu sindroma motoričkog oštećenja neprogresivne prirode koji su posljedica lezije ili anomalija mozga u ranim fazama njegova razvoja31.Ovo stanje prvenstveno je vezano uz poremećaj posture i pokreta, no prate ga brojna dodatna oštećenja i sekundarni problemi koji mogu imati veliki utjecaj na djetetov zdravstveni status i kvalitetu života. U okviru zdravstvenog statusa djece s cerebralnom paralizom treba posebno izdvojiti određene sastavnice zdravlja na koje može povoljno djelovati tjelesna aktivnost, tako da možemo govoriti o zdravstvenom fitnesu ove djece13. Istraživanja su pokazala da osobe cerebralnom paralizom moraju održavati više razine fizičke spremnosti od opće populacije kako bi odgodila opadanje funkcionalnih sposobnosti organizma vezano uz procese starenja i posljedice primarnih oštećenja organizma33. Suvremena medicinska, kineziološka i rehabilitacijska znanost danas nude mogućnosti kako odabranim konceptima, programima i postupcima, djelovati u smislu prevencije, očuvanja ili unapređenja zdravstvenog fitnesa djece i osoba s cerebralnom paralizom.U ovom pregledu stoga su istaknute neke specifičnosti morfološke, mišićne, motoričke i kardiovaskularne odrednice zdravstvenog fitnesa djece s cerebralnom paralizom. Također su izdvojeni terapijski i kineziološki usmjereni programi tjelesne aktivnosti kojima je moguće utjecati na promjene navedenih odrednica u djece s cerebralnom paralizom, a koji će im ujedno pomoći u postizanju optimalne razine samostalnosti i aktivne participacije u svakodnevnom životu. Cerebral palsy refers to a group of non-progressive motor impairment syndromes caused by a brain lesion or anomaly in its early developmental stage. This condition is primarily associated with posture and movement disturbances, along with associated conditions and secondary problems that may significantly influence children’s overall health status and quality of life. When assessing the health status of children with cerebral palsy we should separately observe those special determinants of health that physical activity may influence positively. Therefore, we may consider the health-related fitness of these children. Research has shown that individuals with cerebral palsy must achieve and maintain higher levels of physical fitness than the general population in order to delay functional decreases due to aging and the consequences of disabling conditions. Modern medicine, kinesiology, and rehabilitation science now offer ways to prevent, maintain or improve health-related fitness in children and adults with cerebral palsy using selected concepts, programs and procedures. This overview sets forth separate observations of various determinants of morphological, muscular, motor and cardiovascular aspects of health-related fitness in children with cerebral palsy. In addition, special attention is given to therapeutically- and kinesiologically-directed programs incorporating types of physical activity that may influence changes in the above-mentioned determinants in children with cerebral palsy while, at the same time, helping children to achieve an optimal level of independence and take an active part in day-to-day activities.

UČINAK TRANSPORTA I ZAKAŠNJELE ANALIZE HEMATOLOŠKIH VARIJABLA U UZORCIMA KRVI UZETIH OD VRHUNSKIH BRZIH KLIZAČA EFFECT OF TRANSPORT AND DELAYED ANALYSIS ON HEMATOLOGICAL VARIABLES IN BLOOD SAMPLES TAKEN FROM ELITE SPEED SKATERS Kuipers, Harm Dubravčić-Šimunjak, Sanda Moran, Jane Mitchell, David Shobe, Joel Sakai, Hiroya Ambartsumov, Ruben sport; testiranje krvi; skladištenje; transport; hematologija sport; blood testing; storage; transport; hematology Cilj rada bio je ispitati utjecaj transporta i skladištenja uzoraka krvi na stabilnost hematoloških varijabli. Dva uzorka krvi uzeta od 81 vrhunska brza klizača na kratke staze analizirana su unutar 4 sata nakon uzimanja. Jedan je uzorak ponovno analiziran nakon 24 sata. Po prvoj analizi, drugi je uzorak transportiran, cestovnim i zračnim prometom te ponovno analiziran nakon 24 sata. Kako bi se odredio utjecaj skladištenja uzoraka tijekom 48 sati, u 31 vrhunska brza klizača na duge staze, jedan je uzorak krvi analiziran unutar 4 sata nakon uzimanja te ponovno nakon 24 i 48 sati. Transport i skladištenje uzoraka krvi tijekom 24 sata nisu značajno promijenili koncentraciju hemoglobina i % retikulocita. Hematokrit te razlika između ukupnog hemoglobina i koncentracije staničnog hemoglobina povećala se nakon 24 sata (p<0.01). U uzorcima koji su bili uskladišteni tijekom 48 sata, koncentracija hemoglobina ostala je stabilna tijekom cjelokupnog vremenskog perioda. 24 sata nakon skladištenja došlo je do porasta srednjeg volumena eritrocita (MCV-a) (p<0.05), a 48 sati nakon skladištenja došlo je i do porasta hematokrita (p<0.05) te postotka i broja retikulocita (p<0.01). Koncentracija hemoglobina i postotak retikulocita ostaju stabilni i od 24 sata nakon uzimanja uzoraka krvi, dok hematokrit može porasti. Nakon 24 sata od uzimanja uzorka krvi raste hematokrit, MCV, postotak i broj retikulocita. Kada je uključen i transport uzoraka, može doći do njihove hemolize. To study the effect of transport and storage on the stability of hematological variables, two blood samples from 81 elite short track speed skaters were analyzed within four hours after sampling. One sample was analyzed again 24 hours later. After analysis, the second sample was subjected to road and air transport and analyzed a third time 24 hours after the second analysis. To study the effect of storage up to 48 hours, one blood sample was taken from each of 81 elite long track speed skaters and subsequently analyzed within four hours after sampling, and again after 24 and 48 hours. Transporting the blood samples and storing them for 24 hours did not significantly change hemoglobin concentration and % reticulocytes. Hematocrit and the difference between total measured hemoglobin and cellular hemoglobin concentration were increased after 24 hours (p<0.01). In samples stored for 48 hours, hemoglobin concentration remained stable for up to the entire 48-hour time period. In contrast, after 24 hours the mean cellular volume (MCV) increased (p<0.05). After 48 hours hematocrit (p<0.05), percentage and number of reticulocytes increased 48 hours after sampling (p<0.01). In conclusion, hemoglobin concentration and percentage of reticulocytes may remain stable for up to 24 hours after sampling, while hematocrit may increase during this time period. Furthermore, hematocrit, MCV, and percentage and number of reticulocytes may also rise during the 24 hours after sampling. However, when transport is involved hemolysis may occur.

OPTEREĆENJE TENISAČA NA RAZLIČITIM PODLOGAMA A COMPARISON OF TENNIS PLAYERS' LOADS ON TWO DIFFERENT COURT SURFACES Barbaros Tudor, Petar Matković, Branka R. Novak, Dario tenis; zemlja; betonska podloga; opterećenje tennis; clay; hard court; load Cilj ovoga istraživanja je usporediti opterećenje tenisača s obzirom na igru na različitoj podlozi – beton i zemlja. U tu svrhu 20 tenisača seniorskog uzrasta, koji su bili rangirani na ATP ljestvici odnosno do 25 mjesta rang liste Hrvatskog teniskog saveza, odigrali su 20 susreta. Od ukupnog broja 10 susreta su igrali na zemljanoj podlozi, a 10 susreta na betonskoj podlozi uz uvjet da su isti parovi igrača odigrali susrete na obje podloge. Svaki susret je snimljen s dvije kamere radi dobivanja što pouzdanijih podataka vezanih uz osnovnu tenisku statistiku. Procjena fiziološkog opterećenja na teniskom terenu provedena je praćenjem frekvencije srca i koncentracije laktata. Zaključeno je kako je u ovom istraživanju kod istih parova igrača podloga utjecala na različitu distribuciju opterećenja koje je izazvalo značajno povećanje frekvencije srca i energetsku potrošnju tijekom igre na zemljanoj podlozi. Interesantno je da distribucija opterećenja i duže trajanje pojedinih dijelova igre (poena, gema) nije utjecalo na razliku u ukupnom broju odigranih poena po satu igre. Dakle po satu susreta na betonskoj podlozi se nije odigralo više poena, ali je loptica na zemljanoj podlozi duže bila u igri tijekom poena, gema i susreta. Poeni se po svojoj strukturi i zahtjevnosti razlikuju većim brojem udaraca, dužim i većim brojem izmjena u poenu i gemu, što tijekom sata igre dovodi do značajno veće energetske potrošnje na zemljanoj podlozi. The aim of this study was to compare tennis players’ physiological demands on different tennis surfaces: clay court and hard court. The study included twenty senior players aged 21.45±3.45, from ATP (from 400 ATP) to national level (to 25th place in Croatia’s national rankings). They played 20 matches, 10 on a clay court and 10 on a hard court. Same pairs of players played on both surfaces (hard court - clay court). All matches where recorded using two digital video cameras in order to obtain reliable match statistics data. The demands of tennis match play were assessed by monitoring heart rate and lactate level. Based on the results of the study, it was concluded that, for the same pairs of players, the type of court surface impacted physiological demands differently, thus yielding higher heart rates and higher energy expenditures during match play on the clay court. Interestingly, differences in energy demands on the clay court when certain parts of match play (point, games) lasted for longer periods of time did not produce significant differences in the number of points played out during a one-hour match period. Thus, in one hour of match play, more points were not achieved on the hard court, but the ball was in play for a significantly longer period of time during the points, games, and during the one-hour period of match play. The points differed in terms of structure and demands because, during the match play on the clay court, the players performed more strokes, and the duration of the rallies, points, and games was longer. These factors provide a primary explanation as to why energy expenditures wee higher on the clay court surface.

ZDRAVSTVENE NAVIKE KOŠARKAŠKIH TRENERA HEALTH-RELATED HABITS OF BASKETBALL COACHES Bojan, Matković Swalgin, Kenneth Swalgin2, Kenneth košarka; treneri; tjelesna aktivnost; pušenje; alkohol basketball; coaches; physical activity; smoking; alcohol Cilj ovog istraživanja bio je utvrđivanje razlike između košarkaških trenera u Sjedinjenim Američkim Državama i Hrvatskoj vezano uz njihove zdravstvene navike koje se ubrajaju među čimbenike za obolijevanje od kardiovaskularnih bolesti: tjelesna aktivnost, pušenje, konzumacija alkohola. Uzorak ispitanika sastavljen je od košarkaških trenera: 43 iz Sjedinjenih Američkih Država i 63 iz Hrvatske. Navike pušenja i konzumiranja alkohola ispitane su upotrabom upitnika, a uobičajena tjelesna aktivnost utvrđena je korištenjem Baeckeovog upitnika. Od morfoloških karakteristika izmjerena je visina i masa tijela te su izračunate vrijednosti indeksa tjelesne mase (BMI). Dobiveni podaci obrađeni su standardnim statističkim postupcima statističkim paketom SPSS 13.0. Indeks tjelesne mase ne razlikuje se značajno između trenera dvaju zemalja. Što se tiče usporedbi indeksa tjelesne mase testiranih trenera i opće hrvatske populacije pokazalo se da postoje određene razlike u korist trenera, ali nikako zadovoljavajuće. Američki i hrvatski treneri imaju vrlo slične vrijednosti sva tri izračunata indeksa koji procjenjuju uobičajenu tjelesnu aktivnost. U usporedbi s prosječnom populacijom uočljiva je značajna razlika u korist košarkaških trenera. Puši oko 20% hrvatskih trenera što je dvostruko manje od postotka pušača u ostaloj populaciji te dobi dok američki treneri uoće ne puše. Konzumacija alkohola je vrlo slična kod obje grupe trenera. The aim of this study was to evaluate differences between American and Croatian basketball coaches in their health-related habits regarding usual physical activity, alcohol consumption and smoking. The sample comprised 63 basketball coaches from Croatia and 43 from the United States of America. To determine alcohol consumption and smoking habits, a new questionnaire was constructed based on previous national and international studies. The questionnaire was completed anonymously on a voluntary basis. The Baeckes questionnaire was used to determine usual physical activity. Body height and mass measurements were used to calculate body mass index. The obtained data were analyzed using the statistical software package SPSS 13.0 in accordance with standard statistical procedures. The study revealed no significant difference in body mass index between coaches from both countries. Differences in body mass exist between coaches and the normal population exist but are not satisfactory. Smoking is unfortunately widely accepted. In terms of deaths caused by tracheal, bronchial, and lung cancers, it may be argued that real results are not yet apparent, as these numbers remain very high. Concerning smoking habits, the study found that 20% of all tennis coaches, although none of the American coaches, are smokers. Approximately 75% of coaches consume alcohol, mostly beer and wine. Consumption levels are similar in both groups.

RAZLIKE NEKIH IZOKINETIČKIH POKAZATELJA KOD VRHUNSKIH NOGOMETAŠA DIFFERENCES IN VARIOUS ISOKINETIC INDICATORS IN ELITE SOCCER PLAYERS Bašćevan, Saša Knjaz, Damir Bašćevan, Alen izokinetičko mjerenje;moment sile; ukupni rad; dominantna i nedominantna noga; nogomet isokinetic measurement; peak torque; total work; preferred and non-preferred leg; soccer Cilj ovog rada je utvrditi razlike između dominantne i nedominantne noge u momentu sile i ukupnom radu kod nogometaša prve i druge hrvatske lige, te pomoću tih rezultata ukazati na eventualne nedostatke u omjerima momenta sile i ukupnog rada kao pokazatelje povećanog rizika od ozljede. Istraživanje je provođeno od 2003. do 2007. godine u Centru za kineziološku dijagnostiku i rehabilitaciju pri Daruvarskim Toplicama. Uzorak ispitanika čine 30 zdravih nogometaša prve i druge hrvatske nogometne lige. Razlike su testirane na osnovu momenta sile (peak torque) u njutnmetrima (Nm) i ukupnog rada (total work) u đulima (J) ostvarenog u 6 povezanih ponavljanja ekstenzije i fleksije potkoljenice na Biodex System 3; uređaju za mjerenje izokinetičke sile mišića u 90 i 150 stupnjeva u sekundi s dominantnom i nedominantnom nogom. Statistički značajne razlike dobivene su između varijabli maksimalnog momenta sile dominantne (PTED90 i PTED150) i nedominantne noge (PTEN90 i PTEN150), gdje je maksimalni moment sile dominantne noge kod svih nogometaša bio znatno veći od onog nedominantne noge. Kod pokreta fleksije i u maksimalnom momentu sile i ukupnom ostvarenom radu nije bilo statistički značajne razlike između dominantne i nedominantne noge. U testiranju razlika ukupnog rada jedina statistički značajna razlika je dobivena kod pokreta ekstenzije potkoljenice pri 150 stupnjeva u sekundi u korist dominantne noge, dok isti pokreti pri 90 stupnjeva u sekundi nisu ukazali na statistički značajne razlike. The goals of this study were to determine the difference in peak torque and total work values between legs preferred and not preferred by first and second league Croatian soccer players, and to use these results to draw attention to the shortcomings of peak torque and total work ratios as indicators of a potential higher injury risk. The study was conducted at the Centre for Kinesiological Diagnostics and Rehabilitation in Daruvarske Toplice, Croatia from 2003 to 2007. The sample of examinees consisted of 30 healthy first and second league Croatian soccer players. The differences were tested and evaluated based on peak torque (Nm) and total work (J) values produced through six combined repetitions extending and flexing the preferred and non-preferred lower legs by 90 and 150 deg/sec. on a Biodex System 3 isokinetic machine. A statistically significant difference between the peak torque variables of the preferred (PTED90 and PTED150) and non-preferred (PTEN90 and PTEN150) legs was detected; indeed, the peak torque value of the leg preferred by each soccer player was higher than the value of the non-preferred leg. A comparison of flexion movements revealed no differences either in peak torque or in total work values between the preferred and non-preferred legs. However, an analysis of differences in total work by extension movements demonstrated that a statistically significant difference was achieved only at the angle speed of 150 deg/sec. In contrast, the test conducted at a speed of 90 deg/sec. showed no statistical difference.

RAZLIKE U MORFOLOŠKIM KARAKTERISTIKAMA IZMEĐU VRHUNSKIH HRVATSKIH NOGOMETAŠICA S OBZIROM NA IGRAČKU POZICIJU MORPHOLOGICAL DIFFERENCES OF ELITE CROATIAN FEMALE SOCCER PLAYERS ACCORDING TO TEAM POSITION Sporiš, Goran Čanaki, Martina Barišić, Valentin nogomet; morfološke karakteristike; pozicije igračica soccer; morphological characteristics; team position Istraživanja morfoloških karakteristika u nogometu osobito su složena, jer uspjeh u nogometu ovisi o individualnim karakteristikama igrača i specifičnostima pozicije na kojoj igraju. Spoznaje o navedenim morfološkim karakteristikama važne su u kompleksnim sportskim igrama kao što je nogomet. Ovaj rad logičan je nastavak prethodnog istraživanja provedenog na vrhunskim hrvatskim nogometašima. Uzorak ispitanika sačinjen je od nogometašica Prve hrvatske ženske nogometne lige (n=24). Nogometašice su testirane na kraju natjecateljske sezone 2005/06 (neposredno prije kvalifikacija za Europsko prvenstvo). Mjerenje morfoloških mjera izvršeno je prema napucima Međunarodnog Biološkog Programa. Za potrebe ovog istraživanja izmjereno je 14 morfoloških mjera: visina tijela, tjelesna masa, dužina noge, dužina ruke, širina ramena i kukova, dijametar lakta i koljena, opseg nadlaktice, opseg podlaktice, te opseg natkoljenice i potkoljenice. Postotak potkožnog masnog tkiva i relativna masa potkožnog masnog tkiva kod nogometašica određene su jednadžbama Sloan-a i Siri-ja. Razlike u morfološkim karakteristikama s obzirom na igračku poziciju (vratari, obrambeni igrači, napadači i vezni igrači) analizirani su Multivarijatnom analizom varijance MANOV-om, s statističkom značajnošću od p<0.05. U skladu s njihovim građom tijela utvrđeno je da su igračice na golu više i teže od igračice u polju. Multivarijatna analiza varijance nije pokazala postojanje statistički značajnih razlika između igračkih pozicija nogometašica. Dobiveni rezultati nogometašica u skladu su sa rezultatima prosječne populacije (vrijednosti visine tijela i mase tijela). Rezultati vrhunskih hrvatskih nogometašica slični su rezultatima koji su dobiveni na uzorcima vrhunskih europskih nogometašica. Možemo zaključiti da su hrvatske nogometašice u morfološkim karakteristikama slične vrhunskim europskim nogometašicama. Dobiveni podaci o morfološkim karakteristikama mogu koristiti trenerima u procesu selekcije igračica za određene igračke pozicije, a posebice za igračice na golu. The research regarding the influence of morphological characteristics on soccer performance is particularly complex because the success in soccer in part depends upon the individual characteristics and team position of every player. It is necessary to have knowledge of these characteristics in order to establish their importance as key factors of success in competitive sports such as soccer. This is one reason why the authors decided to determine the morphological differences of elite Croatian female soccer players according to their respective team positions, a logical extension of an earlier article focusing on male soccer players. The sample consisted of soccer players who were current members of first league clubs in Croatia (n=24) and who were tested at the end of the 2005/06 competition season (prior to the European championship). According to the instructions issued by the International Biological Program, the following anthropometrical variables were measured: body height, body mass, leg length, arm length, biacromial and bicristal diameters, knee and elbow diameters, upper arm girth, forearm girth, thigh girth and calf girth. The body fat percentage and relative body fat mass in female soccer players were determined using the Sloan and Siri equations. The differences in team position (goalkeepers, defenders, forwards and midfielders) were analyzed using a multivariate analysis of variance (MANOVA). The statistical significance was set at p<0.05. The goalkeepers proved to be the tallest and the heaviest players on the team, with longest legs and arms, and the largest thigh girth. The MANOVA revealed no statistically significant differences in any of the selected parameters among female soccer players according to their team positions. An analysis of the female soccer players’ team positions demonstrated no significant differences in morphological variables. The players’ values (average height and body mass) fell within the range of normal values recorded in the general population and other elite European female soccer players. Therefore, we can conclude that Croatian female soccer players are morphologically similar to their counterparts on other elite European soccer teams. These findings are useful because a consideration of morphological characteristics is important in the selection of players, especially goalkeepers, for team positions.

STRUKTURA MORFOLOŠKOG PROSTORA STUDENTICA U ZAGREBU STRUCTURE OF MORPHOLOGICAL SPACE IN FEMALE UNIVERSITY STUDENTS Caput-Jogunica, Romana Ćurković, Sanja studentice; morfološki prostor; sedentarni način života female university students; morphological space; sedentary lifestyle Na uzorku 101 studentice prve i druge godine Agronomskog fakulteta u Zagrebu primjenjen je skup od 20 morfoloških mjera u svrhu utvrđivanja latentne strukture morfološkog prostora te paremetara i distribucije morfoloških varijabli na uzorku studentica. U mjerenju su korišteni propisi Internacionalnog biološkog programa. Primjenjena je eksplorativna faktorska analiza u realnoj metrici s orhoblique rotacijom. Broj značajnih latentnih dimenzija određen je GK kriterijem. Ekstrahirana su četiri orthoblique faktora, od kojih su interpretirana tri faktora: faktor longitudinalne dimenzionalnosti skeleta, faktor volumena i mase tijela subsumiran potkožnim masnim tkivom i faktor transverzalne dimenzionalnosti skeleta. U 21. stoljeću susrećemo se s izrazitim problemima koji se odnose na nedostatnu tjelesnu aktivnost djece i mladeži te sve više rasprostranjenog sedentarnog načina života. Sustavno praćenje morfoloških karakteristika studentica i razine tjelesne aktivnosti u nastavi tjelesne i zdravstvene kulture i izvannastavnim aktivnostima, pridonosi ostvarivanju propisanih ciljeva i zadaća nastave te je jedan od načina kojim možemo preventivno utjecati na zdravstvene probleme uzrokovane uslijed nezadovoljavajuće razine tjelesne aktivnosti studentica. studentice, morfološki prostor, sedentarni način života A battery of 20 morphological measurements was taken using a sample of 101 female university students within the University Of Zagreb Faculty Of Agriculture. The selected measurements evenly reflect an existing model of the morphological space established by the International Biological Programme. An approach involving explorative factor analysis was applied to the study, and a number of significant latent dimensions were determined using the Grübler–Kutzbach (GK) criterion and orthoblique rotation. We were consequently able to interpret three factors: longitudinal dimensionality, volume and body mass analyzed in conjunction with subcutaneous fat tissue, and transversal dimensionality. Sedentary habits are highly prevalent in most European countries. Numerous studies and recent research confirm concerns over insufficient physical activity among young people as well as the increasing frequency of a phenomenon popularly called “the couch potato society.” Systematic observations of morphological measurements and the participation of university female students in physical activity have contributed to the pursuit of the aims and mission of physical education programs. Furthermore, these approaches may serve as a preventive measure designed to reduce the incidence of health problems attributed to a lack of physical activity.

SINDROM PREDNJEG ODJELJKA POTKOLJENICE PRIKAZ SLUČAJA ANTERIOR COMPARTMENT SYNDROME OF THE LEG: A CASE REPORT Grdošić, Davor Lucijanić, Ivica Ćapin, Tatjana Pećina, Marko sindrom prednjeg odjeljka potkoljenice; klinička slika i dijagnoza; kreatin-kinaza; fasciotomija anterior exertional compartment syndrome; clinical features; diagnosis; creatin-kinase level; fasciotomy Sindrom prednjeg odjeljka potkoljenice može se javiti kao akutni oblik s brzim razvojem ishemičnih promjena, osobito u prednjem tibijalnom mišiću, zbog čega se i naziva "sindrom m. tibialis anteriora" ili "tibialis anterior syndrome", ili u kroničnom obliku koji nastaje postepeno i koji se ubraja u sindrome prenaprezanja i jedan je od uzroka nastanka tegoba poznatih pod imenom „trkačka potkoljenica“. Iznosimo prikaz slučaja akutnog oblika sindroma prednjeg odjeljka potkoljenice u sportaša rekreativca, a osim toga po zanimanju poštara koji je prije nastanka sindroma učestalo nosio terete po stepenicama. Bolesnik u dobi od 40 godina javio se u ortopedsku ambulantu zbog otoka i nesnosnih bolova u području prednjeg dijela lijeve potkoljenice. Odmah je postavljena klinička dijagnoza početnog akutnog sindroma prednjeg odjeljka potkoljenice s još uvijek očuvanom arterijskom cirkulacijom i bez neuroloških ispada..Rutinski laboratorijski nalazi su bili u granicama normale osim nalaza kreatin-kinaze koja je iznosila 1124 U/L (referentne vrijednosti do 177). Indicirana je hitna fasciotomija,tj. dekompresija prednjeg odjeljka potkoljenice, koja je izvedena otvorenim pristupom. Intraoperativno bile su vidljive početne ishemične promjene mišića,ali bez znakova nekroze mišićnog tkiva. Nakon provedene fasciotomije stavljeni su rijetki adaptacijski šavovi kože. Postoperacijski tijek je protekao uredno,a kontrolirani laboratorijski nalazi kreatin -kinaze drugi postoperacijski dan iznosili su 422 U/L dok su peti dan već bili na normali,tj. inosili su 112 U/L. Nakon uredno zaraslog postoperacijskog ožiljkas i provedene ambulantne fizikalne terapije bolesnik se vratio sportskim aktivnostima i redovnom poslu 5 tjedana nakon početka liječenja. Za akutni sindrom prednjeg odjeljka potkoljenice bitno je posumnjati na postojanje sindroma i postaviti ranu dijagnozu, a nakon potvrđene dijagnoze hitno izvesti fasciotomiju kao metodu izbora u liječenju. Nalaz povišenih vrijednosti kreatin –kinaze doprinosi potvrđivanju sumnje na akutni oblik sindroma, a dinamika vrijednosti kreatin-kinaze može pomoći u praćenju i procjeni tijeka poslije operacije Ključne riječi: sindrom prednjeg odjeljka potkoljenice, klinička slika i dijagnoza, vrijednosti kreatin-kinaze,fasciotomija Anterior compartment syndrome of the leg may appear in an acute form characterized by a rapid development of ischemic changes, especially in the anterior tibial muscle, which is why it is called “syndrome m. tibialis anteriora” or “tibialis anterior syndrome,” or in a chronic form which develops gradually and is considered an overuse injury and can lead to the condition known as shin splints or “runner's leg.” We present a case involving an acute form of anterior compartment syndrome in a recreational sportsman, a postman who often had to climb stairs carrying heavy packages prior to the onset of the syndrome. The patient, 40 years of age, checked into the orthopedics clinic complaining of swelling and unbearable pain in the anterior part of the left lower leg, He was immediately diagnosed with an early stage of acute anterior compartment syndrome with arterial circulation still intact and no neurological incidents. Routine laboratory tests showed normal results except the creatine kinase value, which was 1124 U/L (the upper limit of the reference range is 177). He was processed for an urgent fasciotomy, a decompression of the anterior compartment, which was performed as an open procedure. During the surgery we found ischemic muscle changes, but no signs of muscle tissue necrosis. After the fasciotomy the skin was sutured using adaptive stitches. Postoperatively the patient was well, and control laboratory tests revealed creatine kinase values of 422 U/L on the second day following the surgery and 112 U/L, or normal, on the fifth day after the surgery. After the scar healed nicely and the patient completed physical therapy, he went back to work and resumed his athletic activities five weeks after starting the treatment. With regard to anterior compartment syndrome, the condition should be suspected and diagnosed as early as possible. After confirmation of the diagnosis, an urgent fasciotomy should be performed as a first-line treatment option. The presence of elevated creatine kinase levels may be used, at least in part, to confirm a suspected acute form of the syndrome, while changes in creatine kinase levels may be used to help monitor and evaluate a patient’s postoperative progress.

PLANTARNI FASCITIS PLANTAR FASCIITIS Jeleč, Željko; Opća bolnica „Dr. Ivo Pedišić, Sisak Cicvara-Pećina, Tatjana; Zavod za radiologiju KB Dubrava, Zagreb Klobučar, Hrvoje; Specijalna bolnica za ortopediju i traumatologiju „Akromion“, Krapinske Toplice Bićanić, Goran; Klinika za ortopediju KBC Zagreb i Medicinskog fakulteta u Zagrebu, Zagreb Jelić, Miroslav; Zavod za ortopedska pomagala i rehabilitaciju KBC Zagreb, Zagreb Pećina, Marko; Medicinski fakultet Sveučilišta u Zagrebu plantarni fascitis; uzroci nastanka;klinička slika; dijagnostika; liječenje planatar fasciitis, etiopathogenesis, clinical presentation, diagnostics, treatment Plantarni fascitis spada u sindrome prenaprezanja,a oèituje se pojavom boli u području medijalne kvrge petne kosti i / ili uzduž medijalnog uzdužnog svoda stopala. Nastaje zbog dugotrajnih ponavljajućih opterećenja (stress) na plantarnu fasciju te dolazi do mikroruptura ili u završnoj fazi i do djelomične i/ili potpune rupture fascije blizu njenog polazišta na petnoj kosti. Plantarna fascija ima veliki značaj u biomehanici stopala i ona tijekom hoda ublažava mehaničke udare na stopalo i odrazuje stopalo prema naprijed po sistemu dizalice. Ukoliko doðe do poremećaja biomehanike stopala osobito naglašene pronacije stopala, zatim ako postoji udubljeno stopalo, skraćena Ahilova teiva, izrazito spušteno stopalo, itd. dolazi do pojačanih rastezanja plantarne fascije,a zbog same graðe fascije izrazito je mala mogućnost prilagodbe na ta povećana rastezanja. U sportaša plantarni fascitis češće se javlja kod trkača na duge pruge, a veća incidencija nalazi se i kod tenisaèa, košarkaša te plesača. Obično je unilateralan a u 15% pacijenata pojavljuje se obostrano. Klinička manifestacija plantarnog fascitisa je bolno stopalo, odnosno bolnost plantarnog dijela petne kosti.Dijagnoza plantarnog fascitisa se kod većine pacijenata postavlja na osnovi anamneze i klinièkog pregleda. Točka najjače bolne osjetljivosti je medijalni nastavak petne kvrge a bol se pojaèava pasivnim rastezanjem fascije. U dijagnostici plantarnog fascitisa koriste se radiološke pretrage koje često otkrivaju postojanje koštanog trna (calcar calcanei), ultrazvučna dijagnostika i danas sve više i MRI otkrivaju zadebljanje fascije, burze i rupture a uz scintigrafsku pretragu MRI je koristan i u diferncijalnoj dijagnozi prijeloma zamora petne kosti. U lijeèenju plantarnog fascitisa pogotovo u sportaša prvenstveno treba primjenom individualno izraðenih ortotskih pomagala korigirati poremećenu biomehaniku stopala, što treba provoditi i u preventivne svrhe. U konzervativno liječenje spadaju i svi inače uobičajeni postupci fizikalne medicine od krioterapije,vježbi rastezanja , primjene noćne udlage, lokalne primjene ultrazvuka ili u novije vrijeme udarnih valova velike energije do posebnih bandaža stopala. Kirurško liječenje otvorenom ili endoskopskom metodom sastoji se u opuštanju,presijecanju ili/i djelomiènom odstranjenju promijenjene plantarne fascije.Kirurško liječenje poduzima se najčešće upravo u sportaša nakon 6-12 mjeseci neuspješnog konzervativnog liječenja. Plantar fasciitis is an overuse injury characterized by pain at the medial tubercle of the calcaneus and/or along the medial longitudinal arch of the foot. It usually develops when repetitive and prolonged stress is placed on plantar fascia, which may cause microtears and/or partial or total tears of the fascia near its insertion to the calcaneus. Plantar fascia plays significant role in the foot biomechanics. It absorbs mechanical forces placed on the foot and propels foot forward by utilizing the windlass effect. In deranged foot biomechanics, like in pronation of the foot, pes cavus, shortened Achilles tendon, extreme pes planus, etc., additional stress and elongation of plantar fascia is observed, which the fascia, because of its anatomy, is unable to compensate. In athletes, plantar fasciitis is more common in long distance runners and increased incidence is observed in tennis players, basketball players and in dancers. It is usually unilateral whereas in 15% of patients it is bilateral. Clinical findings include painful foot with pain across the plantar aspect of the calcaneus. Diagnosis is usually made after anamnesis and clinical examination. The most painful spot is located at the medial tubercle of the calcaneus and pain is aggravated by passive stretching of the fascia. X-rays could be useful for diagnosing bony spur (calcar calcanei) and ultrasound and MRI are useful for diagnosing thickened fascia, bursa or rupture. MRI and scintigraphy are also useful for differentiating plantar fasciitis and stress fracture of the calcaneus. For the treatment of the plantar fasciitis, especially in athletes, custom made orthothic devices are used for correction of the deranged foot biomechanics, even for prevention. For conservative treatment all usual methods are used (physiotherapy, cryotherapy, stretching exercises, orthoses through the night, local ultrasound and shock wave therapy and foot taping). Surgical treatment with endoscopic or open methods includes release and complete or partial removal of deranged plantar fascia. Surgical treatment is most commonly performed in athletes after 6-12 months of unsuccessful conservative treatment.

PSIHOLOŠKE KARAKTERISTIKE MLAÐIH I STARIJIH TRENERA PSYCHOLOGICAL CHARACTERISTICS OF YOUNGER AND OLDER COACHES Kajtna, Tanja; Fakulteta za šport, Ljubljana Cetinić, Jelena; Kineziološki fakultet – doktorski studij, Zagreb treneri; ličnost; socijalne vještine; rukovoðenje; emocionalna inteligencija coaches; personality traits; social skills; leadership; emotional intelligence Cilj istraživanja je utvrditi postoje li razlike u psihološkim karakteristikama kod trenera koji svoj posao obavljaju duži period i koji su kronološki stariji (35 godina i više) s onima koji tek zapoèinju trenerski posao i kronološki su mlaði (do 34 godine starosti). Jedna izmeðu glavnih karakteristika trenerskog posla je naime puno stresnih situacija, kojima su izloženi treneri i zato smo pokušavali ispitati, kako stres utječe na trenere. Provjeravali smo razlike u osobinama ličnosti, motivaciji postignuća, značaju rukovoðenja, socijalnih vještina, emocionalnoj inteligenciji i vrijednostima. Za sve ove karakteristike aplicirali smo psihološke upitnike. Na uzorku 275 slovenskih trenera ustanovili smo da su mlaði treneri savjesniji i više otvoreni prema kulturi i isprobavanju novih pristupa, imaju veću toleranciju i bolje znaju upravljati emocijama. Stariji treneri češće upotrebljavaju demokratsko nego autokratsko rukovoðenje i češće spominju probleme u radu. Neke razlike izmeðu trenera mogle bi biti uzrokovane razlikama u razini edukacije, koje su postigli mlaði i stariji treneri – mlaði treneri bolje su obrazovani. Našli smo dvije smjernice koje idu u korist starijim trenerima - češće naglašavaju izvrsnost i češće upotrebljavjaju delegiranje, dok se kod mlaðih trenera pojavljuje težnja ka češćoj prijaznosti. Naši rezultati pokazuju, da su stariji treneri izloženi većemu stresu i to se odražava na njihovim vrijednostima do trenerskog posla. The purpose of the research was to investigate the differences between the psychological characteristics of coaches who have been working in their field for a longer period of time and are older (age 35+) and those of younger (up to age 34) coaches who have recently begun their coaching careers. One key characteristic of the coaching profession is the significant stress to which coaches are often subjected, and we attempted to investigate whether large amounts of stress affect the coaches' psychological characteristics. We compared differences in personality traits, achievement motivation, leadership characteristics, social skills, emotional intelligence, and values. To assist in analysing each of these characteristics, we applied suitable psychological questionnaires. 275 Slovene coaches participated in this study, and we found the younger coaches to be more conscientious, more interested in cultural activities, more open to new experiences, and more tolerant. Furthermore, we observed that the younger coaches have achieved a better level of control over their emotions. Older coaches tend to be more democratic leaders, use less autocratic approaches, and report job – related problems more frequently. Some of these differences may be attributed to disparate levels of education, as younger coaches are generally better educated than their older counterpairs. We found two characteristics that favour the older coaches – they tend to emphasise the importance of excellence and are more likely to delegate leadership tasks, whilst younger coaches could be described as friendlier. Our results show that older coaches are exposed to more stress, which is reflected mainly in their attitudes towards their professional values.

TRENING JAKOSTI U STARIJIH OSOBA STRENGTH TRAINING IN THE ELDERLY Mišigoj Duraković, Marjeta; Zavod za kineziološku antropologiju i metodologiju, Kineziološki fakultet Sveučilišta u Zagrebu Duraković, Zijad; Odjel za medicinsku antropologiju, Institut za antropologiju u Zagrebu Matković, Branka R.; Zavod za kineziološku antropologiju i metodologiju, Kineziološki fakultet Sveučilišta u Zagrebu starenje; trening jakosti; sarkopenija aging; resistance training; sarcopenia Niska razina tjelesne aktivnosti i funkcijska sposobnosti dio je loših navika življenja današnjeg pučanstva tzv. razvijenog dijela svijeta. Povezuje se s pojavnošću mnogih kroničnih bolesti u odrasloj i starijoj životnoj dobi. Hrvatska s visokim udjelom tjelesno nedovoljno aktivnih odraslih osoba mlaðe, srednje i starije životne dobi pri tome nimalo ne zaostaje za svijetom. Javnozdravstvene preporuke vodećih svjetskih zdravstvenih udruga i ustanova usmjerene su k povećanju stupnja zdravlja i funkcijske sposobnosti te prevenciji kroničnih bolesti srčanožilnog sustava i metabolizma primjenom programa tjelesnih aktivnosti. Trening jakosti danas je uz aerobnu komponentu i komponentu fleksibilnosti, dio preporučenih programa vježbanja u očuvanju i unaprjeðenju zdravlja i sprječavanju kroničnih bolesti u odraslih osoba i osoba starije životne dobi. Tijekom starenja dolazi do smanjenja motoričkih jedinica, čija je posljedica gubitak mišićnih vlakana tipa I i tipa II, i smanjenja poprečnog presjeka mišićnih vlakana, posebno mišićnih vlakana tipa II. Takva zbivanja tijekom starenja dovode do smanjenja mase i jakosti mišića – sarkopenije. Mehaničko opterećenje koje trening jakosti proizvodi može smanjiti procese starenja u mišićima, odnosno uz odgovarajući volumen i intenzitet uvjetovati povećanje poprečnog presjeka preostalih mišičnih vlakana. Najznačajniji učinci treninga jakosti u odraslih i starijih osoba ogledaju se i čine zasigurno najučinkovitiji postupak u održanju, odnosno povećanju mišićne jakosti i izdržljivosti te koštane mase i u povezanosti s time veću funkcijsku sposobnost obavljanja svakodnevnog rada te očuvanje samostalnosti i mobilnosti u starosti. No, zadnjih desetljeća rastući je broj istraživanja i o drugim pozitivnim zdravstvenim učincima treninga jakosti o kojima se mnogo se rjeðe govori. Pri tome mislimo na učinke treninga jakosti na čimbenike i pokazatelje povezane s priječenjem kroničnih bolesti, najčešće srèčanožilnih i metaboličkih. Starije osobe su vjerojatno populacija u društvu koja može najviše profitirati od redovite tjelesne aktivnosti. Sigurno je da se može preporučiti i trening izdržljivosti i trening jakosti, meðutim mora se imati na umu da samo trening jakosti može izazvati povećanje mišićne mase i jakosti mišića, dakle djelovati na sarkopeniju koja je uobičajena kod starijih osoba. Povećanje jakosti kod starijih osoba vodi povećanju kvalitete njihova života i većoj samostalnosti. Imajući na umu neobično velike pozitivne učinke aerobnog vježbanja vjerojatno je najbolja preporuka za starije osobe kombinacija treninga jakosti i treninga izdržljivosti. Low level of physical activity and, consequently, low level of physical fitness is a part of poor living habits in today's society. In addition,it is related to the incidence of many chronic diseases in adult and old age. Because of that, different forms of exercise training are today included in public health recommendations. For many years these recommendations were limited to aerobic and flexibility exercises, but today resistance exercise training is recognized as a powerful tool for health improvements. During the aging process significant reductions in muscle mass and muscle strength occur (sarcopenia). This reduction is visible in slow-twich and fast-twich muscle fibers, as well as in muscle cross-sectional area. The metabolic effects of reduced muscle mass lead to a high prevalence of obesity, insulin resistance, type 2 diabetes, dyslipidemia and hypertension. These risk factors are associated with abnormalities in cardiovascular structures and function. There is a large body of scientific evidence suggesting that resistance training prevents the loss of muscle mass and function when the mechanical stimuli provided by common tasks of daily living are not sufficient to offset aging declines. The increase in muscle mass may reduce multiple cardiovascular disease risk factors. Older people are probably a part of society that could profit the most from resistance training. Aerobic training as well as flexibility exercises can be suggested, but it has to be kept in mind that only resistance training can produce hypertrophy of muscles and strength gains. Enhanced strength in the elderly provides better functional capacity as well as independence, and leads to a greater overall quality of live. Bearing in mind the significant positive health effects of aerobic training, probably the best recommendation for elderly would be to combine resistance training with aerobic training.

VREDNOVANJE NATJECATELJSKE AKTIVNOSTI DJECE U ATLETSKIM DISCIPLINAMA OLIMPIJSKOG FESTIVALA DJEČIJIH VRTIĆA PRELIMINARY EVALUATION OF THE CHILDREN'S COMPETITIVE PERFORMANCE IN TRACK & FIELD EVENTS AT THE OLYMPIC FESTIVAL OF KINDERGARTENS Babić, Vesna; Faculty of Kinesiology, University of Zagreb Caput-Jogunica, Romana; Faculty of Agriculture, University of Zagreb Jelovčić, Ines; Faculty of Humanities and Social sciences, University of Zagreb de Privitellio, Sergio; Faculty of Humanities and Social sciences, University of Zagreb djeca; atletske discipline; vrednovanje postignuća children; track & field events; performance evaluation Provedeno je istraživanje na uzorku od 512 djevojčica i 548 dječaka, prosječne dobi šest godina, sudionika na Olimpijskom festivalu dječjih vrtića tijekom 2007. godine. Analizirani su rezultati u tri atletske discipline; trčanje na 50 m, skok udalj iz mjesta i bacanje loptice. Izračunata je i utvrðena razlika izmeðu pojedinih subuzoraka u odnosu na spol u pojedinim atletskim disciplinama. Predložene su ocjene i bodovi vrednovanja pojedinih natjecateljskih postignuća procijenjeni pomoću tablica i dijagrama frekvencija razvrstanih u deset razrednih skupina. Ovaj prijedlog bodova i ocjena za vrednovanje postignuća u atletskim disciplinama za predškolce je prvi prijedlog koji bi se mogao uz eventualnu dodatnu provjeru koristiti kao novi način bodovanja u novim sustavima natjecanja (npr. višeboju) za djecu predškolske dobi i nižih razreda osnovne škole. This study has been carried out on a sample of 512 girls and 548 boys who participated in “Olympic Festival of Kindergartens” in 2007. The children were, on average, six years of age. We analyzed the results in the following track & field events: 50-m sprint, standing long jump and softball distance throw. The aim of the study was to determine the gender differences in all of the observed events. For that purpose, we created a proposal for the evaluation of children's performance in each event. The proposal for evaluation, that has been estimated using frequency tables and charts, consists of marks and points arranged in ten clusters. It is important to stress that this is the first proposal for the evaluation of children's performance in track & field events. We think that our proposal could be used as a new method of performance evaluation in certain track & field competitions as well as in children's competitions in kindergartens as well as in schools.

Istraživanjem je bilo obuhvaćeno 39 odbojkašica, hrvatskih reprezentativki seniorskog i juniorskog uzrasta u dobi od 14 do 30 godina. Ispitanice su testirane skupom od 14 varijabli, od kojih je 10 služilo za procjenu funkcionalno-motoričkih sposobnosti, a 4 za procjenu morfoloških karakteristika. Razlike izmeðu startera i rezervi utvrðene su t-testom za nezavisne uzorke na razini p<0,05. Statistički značajne razlike utvrðene su u varijablama tjelesna visina (TV), dohvat u bloku u stajanju (BLDOHVAT) i dohvat u smeèu u stajanju (SMDOHVAT) koje opisuju morfološki prostor, te dohvat u bloku (SKBLOK) i dohvat u smeču (SKSMEÈ) koje pripadaju skupu funkcionalno-motorièkih varijabli. Iz dobivenih rezultata možemo zaključiti da igračice početne postave tj. starteri postižu značajno bolje vrijednosti od rezervi u varijablama koje opisuju longitudinalnu dimenzionalnost tijela i eksplozivnu snagu tipa skočnosti. Deskriptivni rezultati dviju igračica na dvije različite igrače uloge (dizač i dijagonalni igrač) odabrani su za definiranje vrhunskog modela u pojedinim promatranim varijablama. Takoðer, vrijednosti dobivene mjerenjem kondicijskih i morfoloških obilježja igračica koje su èčlanovi nacionalne odbojkaške reprezentacije i proglašene najboljima na svojim pozicijama tijekom velikih meðunarodnih natjecanja predstavljaju idealan uzorak za definiranje vrhunskog igračkog modela. The aim of this research was twofold. First, we tried to investigate the possible differences in fitness level and morphological characteristics between the group of starters and the group of substitutes. Second, we tried to develop a model of the top-level female volleyball player according to the playing position. Thirty-nine female volleyball players, members of senior and junior national teams, were assessed using fourteen tests (ten tests were used for the fitness level assessment and four tests were used for the assessment of morphological characteristics). Student's t-test for independent samples was employed to inspect possible differences among groups. Significant differences (p < 0,05) were detected for the following variables: body height (TV), standing reach height in block (BLDOHVAT) and standing reach height in spike (SMDOHVAT), block reach (SKBLOK) and spike reach (SKSMEÈ). We can conclude that starters achieved notably higher results in variables describing the longitudinal body dimensions as well as the explosive strength (jumping performance). The results of one player (setter) were chosen for the purpose of defining the model values in the observed variables as this player was proclaimed as being the best in his playing position at important international competitions.

POVEZANOST DJECE 5-8.

Zbog smanjenih motoričkih sposobnosti takva djeca često izbjegavaju sudjelovanje u sportskim aktivnostima što dovodi do zatvorenog kruga tj. do daljnjeg povećanja tjelesne mase. Cilj ovog rada bio je utvrditi koje motoričke sposobnosti su pod najvećim utjecajem povećane tjelesne mase, te da li postoje razlike prema spolu. Uzorak se sastojao od 224 djece koji su bili polaznici 5, 6, 7 i 8-og razreda osnovne škole (prosječna dob 13,07±1,24). Prije početka istraživanja, detaljna objašnjenja postupka ispitivanja te obrazac za suglasnost roditelja poslana su roditeljima djece. Protokol testiranja je obuhvaćao mjerenje morfoloških karakteristika (visina, težina, postotak masti) i različitih motoričkih sposobnosti (brzina, snaga, vrijeme reakcije, ravnoteža mjereni na Kistler Quattro jump force platformi, ravnotežnim platformama i Newtest Powertimer PC sustavu). Za svako dijete je izračunat indeks tjelesne mase i postotak masti, te je pojedinačno svaki ispitanik uvršten u pojedinu skupinu prema stupnju uhranjenosti (nedovoljno uhranjeni, normalno uhranjeni, poveæane tjelesne mase i pretili). U tu svrhu su se koristili grafikoni rasta za dob i spol. ANOVA/MANOVA statistička analiza je ukazala na znaèajan pad sposobnosti s porastom stupnja uhranjenosti u svim motoričkim testovima osim testovima ravnoteže kod dječaka. Nasuprot tome, neočekivano, sposobnosti djevojaka većeg indeksa tjelesne mase se nisu značajno razlikovale od onih nižeg indeksa. Jedini statistički značajno lošiji rezultat deblje djevojke su postigle na testu repetitivnih pokreta donjih ekstremiteta. U zaključku, sportski programi koji se nude u školama morali bi sadržavati i aktivnosti u kojima se dječaci povećane tjelesne mase neće osjećati nedovoljno sposobnima, a možda čak i neke sportove u kojima je bitna ravnoteža kao pokazatelj koji je najmanje pod utjecajem tjelesne mase kao npr. skateboard i sl. An increased body mass in children is usually associated with a decrease in athletic performance. Because of the poorer performance, children tend to avoid the participation in sport activities. This leads to the vicious circle resulting in further increase in body weight. The aim of this study was to identify the motor abilities which are most affected by the body mass increase and to investigate the possible differences in the influence of body mass index on motor abilities with regard to sex. The sample comprised 224 children attending 5th, 6th , 7th and 8th grade of the elementary school (mean age 13,07±1,24). Prior to testing, the detailed explanations of the testing procedure as well as the parental consent form were distributed to the parents. The children underwent testing procedure encompassing measurements of morphological characteristics (height, weight, body fat percentage) and motor abilities (various tests for speed, power, reaction time and balance performed on Kistler Quattro jump force platform, balance boards or Newtest Powertimer PC system). For each child the body fat percentage and body mass index were calculated. Each subject was checked on percentile growth chart for children and classified into one of four categories: underweight, normal weight, overweight or obese. The ANOVA/MANOVA analysis showed, in boys, a significant decrease in all tested motor abilities with the increase of body weight except for the balance board performance. On the contrary, the athletic performance in girls was not significantly influenced by the increase of body mass index. The only test in which the decrease in performance in girls was noted was the test measuring the frequency of lower legs repetitive movements. In conclusion, as the overweight boys of that age do not perform in sport activities as good as their leaner counterparts do, we think that a special attention should be paid to the selection of the sport activities offered for boys in school sport clubs. We have seen here that the balance is still well preserved, regardless of the body mass, so it might be a good choice to offer skateboard classes or similar activities.

ULOGA PSIHOLOŠKIH ČIMBENIKA U PROCESU STJECANJA SKIJAŠKIH ZNANJA THE ROLE OF PSYCHOLOGICAL FACTORS IN THE ALPINE SKIING LEARNING PROCESS OF NOVICE SKIERS Cigrovski, Vjekoslav; Kineziološki fakultet Sveučilišta u Zagrebu Matković, Bojan; Kineziološki fakultet Sveučilišta u Zagrebu Ivanec, Dragutin; Filozofski fakultet Sveučilišta u Zagrebu skijaški početnici; proces učenja; spol; briga; samoprocjena vlastite efikasnosti; stra novice skier; learning process;gender differences; anxiety;self-efficacy, fear Psihološki faktori važni su za uspjeh vrhunskih sportaša. Uloga psiholoških osobina meðutim, je znatno manje istražena prilikom učenja novih motorièkih aktivnosti, a posebno alpskoga skijanja. Cilj ovog istraživanja je pokušati utvrditi povezanost straha od ozljede, samoprocjene vlastite efikasnosti i brige s procesom usvajanja skijaških znanja. Isto tako ovim istraživanjem pokušala se utvrditi razlika izmeðu muških i ženskih ispitanika u promatranim varijablama. U istraživanju je sudjelovalo 126 studenata, koji prije ovog istraživanja nisu imali doticaj s alpskim skijanjem, niti su ga ikada probali. Neposredno prije sedmodnevnog procesa poučavanja, ispitanici su ispunili tri različita psihološka upitnika, a nakon završenog procesa poučavanja dobili su ocjene za pet odabranih elemenata skijaške tehnike ocjenama od jedan do pet. Rezultati su pokazali statistički značajnu razliku izmeðu muških i ženskih ispitanika samo kod psihološkog čimbenika straha (p=0.03), koji je više bio izražen kod ispitanica. Meðutim, strah nije značajno utjecao na proces učenja alpskoga skijanja. Statistički značajan koeficijent korelacije je utvrðen izmeðu samoprocjene vlastite efikasnosti i uspjeha prilikom demonstracije paralelnog zavoja od brijega (r=0.21), upućujuć kako oni koji su imali procjenu vlastitih sposobnosti na višoj razini, takoðer postižu i bolje rezultate u kompleksnijim elementima skijaške tehnike. Značajni koeficijent korelacije utvrðen je kod ispitanika muškog spola i to izmeðu rezultata upitnika brige i uspjeha prilikom demonstracije zavoja k brijegu (r=0.20), kao i izmeðu rezultata samoprocjene vlastite efikasnosti i uspjeha prilikom demonstracije paralelnog zavoja od brijega (r=0.23). Dobiveni rezultati upućuju kako su navedeni psihološki čimbenici povezani s uspjehom prilikom učenja odreðenih elemenata skijaške tehnike. Ovim istraživanjem pokušalo se je razjasniti povezanost korištenih psiholoških čimbenika prilikom učenja alpskoga skijanja kod skijaških početnika. Psychological factors contribute significantly to the success of elite sportsmen. Their role in the learning process of new motor activities such as alpine skiing has been investigated less thoroughly. This study investigated differences in relationships linking a fear of injury, selfefficacy, and anxiety in a group of beginning alpine skiing students as a function of gender and level of obtained alpine skiing skills. One hundred twenty-six students without any previous knowledge of alpine skiing participated in the study. Prior to the seven-day learning process, they had filled out three separate questionnaires. After the learning process, participants were graded on a scale of one to five according to their demonstrated knowledge of five selected elements of alpine skiing. On average, gender differences were significant only for the psychological trait fear (p=0.03), which was more pronounced in female participants. Nonetheless, fear did not restrict their ability to learn this new motor activity. The only statistically significant correlation was observed between self-efficacy and parallel turn (r=0.21), indicating that learners who are more self-confident achieve better results in more complex elements of alpine skiing technique. Also, when male participants were analysed separately, significant correlations were obtained between anxiety and up-hill turn (r=0.20), as well as between self-efficacy and parallel turn (r=0.23), suggesting that the aforementioned characteristics help students grasp more dynamic elements of skiing. This research provides further insight on how, after the sevenday learning process, alpine skiing performance depends upon an individual skier's psychological dimensions.

PRILAGOÐENO VESLANJE – VESLANJE ZA VESLAČE S INVALIDNOŠĆU ADAPTIVE ROWING – ROWING OR SCULLING FOR ROWERS WITH A DISABILITY Smoljanović, Tomislav; Klinka za ortopediju, Medicinskog fakulteta Sveučilišta u Zagrebu; drsmoljanovic@yahoo.com Bojanić, Ivan; Klinka za ortopediju, Medicinskog fakulteta Sveučilišta u Zagrebu Morrison, Judy; Good Shepherd Rehabilitation Network, 850 South 5th Street, Allentown, Pennsylvania, 18103, U.S.A.

Adaptive Rowing; classification; benefits;risks Prilagođeno veslanje je bilo najmlađi sport na Paraolimpijskim igrama (POI) u Pekingu, Narodna Republika Kina 2008. godine. Iako se na međunarodnoj razini počelo razvijati tek prije desetak godina danas je prilagođeno veslanje rasprostranjeno po cijelome svijetu i dobro je razvijeno što je razvidno iz činjenice da je 12 veslačkih medalja na navedenim POI bilo „podijeljeno“ između 9 država s pet kontinenata. Prilagođeno veslanje je veslanje za osobe s invalidnošću koje ispunjavaju kriterije određene u pravilima za klasificiranje prilagođenog veslanja. Prilagođeno znači da je oprema „prilagođena“ sportašima, a ne da im je „prilagođen“ sam sport. Prilagoðenim se veslanjem bave i žene i muškarci, a trenutno postoje četiri discipline (ženski samac – AW1, muški samac – AM1, dvojac na pariæe – TAMix2x i četverac s kormilarom – LTAMix4+) u kojima se natječu veslači ovisno o stupnju tjelesnog oštećenja. Natjecanja se u svim disciplinama odvijaju na stazi duljine 1000 m. Da bi se veslači s različitim stupnjevima tjelesnih oštećenja mogli natjecati na meðunarodnim regatama pod okriljem FISA-e te na POI moraju biti razvrstani ovisno o stupnju invalidnosti od strane FISA-inih međunarodnih klasifikatora tj. jednog medicinskog i jednog tehničkog klasifikatora. Svrha klasifikacije je osiguravanje što je moguće poštenijeg natjecanja sportaša s različitim stupnjevima tjelesnih oštećenja. Prilagođeno veslanje donosi cijeli niz kako fizičkih tako i psihičkih dobrobiti svojim natjecateljima. Kao i kod svake druge sportske aktivnosti, postoje i određeni rizici po zdravlje i život tijekom bavljenja prilagođenim veslanjem, no oni se znanjem i pravilnom organizacijom mogu svesti na minimum. Adaptive Rowing was the youngest sport at the Paralympic Games in Beijing, Peoples Republic of China 2008. Although its international development started just over 10 years ago, Adaptive Rowing is widespread and well developed. To confirm this, 12 rowing Paralympics medals at the mentioned Paralympic Games were “divided” among nine countries from five continents. Adaptive rowing is rowing or sculling for rowers with a disability who meet the criteria set out in the adaptive rowing classification guidelines. Adaptive implies that the equipment is “adapted” to the user to practice the sport, rather than the sport being “adapted” to the user. Adaptive rowing is open to male and female rowers, and is currently divided into four boat classes: LTAMx4+, TA2x, AW1x and AM1x. The LTAMx4+ and TA2x classes are mixed gender boats. All boat classes compete over a distance of 1,000 meters. In order to compete in a FISA international regatta, including the Paralympic Games, rowers must be classified by a panel of two FISA International Classifiers - one medical and one technical. The objective of this classification is to provide competition that is as fair as possible by grouping athletes according to their ability to perform the particular sport of rowing. Adaptive Rowing brings a variety of benefits including physical and psychological improvements to its competitors. As with any sport, there are certain risks for health and life during Adaptive Rowing, but they can be diminished to a minimum by knowledge and appropriate organization.

Napredak znanosti je doveo do razvoja metoda kojima se ove bolesti sve češće i ranije dijagnosticiraju, ali i sve uspješnije lijeće. Danas postizanje kliničke i laboratorijske remisije bolesti nije jedini cilj. Kada se remisija postigne, otvara se pitanje održavanja što boljeg stanja lokomotornog sustava, unapreðenja kvalitete života i sprečavanja invalidnosti. Dobro osmišljeni progami vježbanja bazirani na znanstveno potvrðenimčinjenicama mogu to i osigurati. U ovom članku donosimo pregled etiologije, kliničke slike i danas dostupne terapije najčešćih reumatskih bolesti u dječjoj dobi, te preporuke i stavove o bavljenju tjelesnom aktivnosti. Takoðer donosimo literaturne podtake o testovima koji se koriste u evaluaciji bolesnika prije i nakon uključivanja u programe tjelesne aktivnosti, te koje sportovi i aktivnosti su najpogodniji za reumatološke bolesnike. Iako postoji sve više radova, još uvijek nema jasnog i ujednačenog stava o vrsti i intenzitetu fizičke aktivnosti koja se preporučuje bolesnicima. Ipak, sudjelovanje u sportskim programima i fizička aktivnost ostaju najbolji način očuvanja kondicije, opsega pokreta u zglobovima i mišićne snage, te samim time i samopouzdanja djece s reumatskim bolestima. Rheumatic diseases in children are increasingly becoming a contemporary problem. Scientific advances have led to the development of diagnostic methods that allow for early diagnosis and successful treatment. Today we do not only aim to achieve clinical and laboratory remission, but also to enable our patients to lead full, normal lives. Physical activity plays an important role in the achievement of this outcome. This article provides an overview of the etiology and clinical features of the most common rheumatic diseases in children, as well as therapeutic possibilities regarding these conditions. This study provides an overview of recently published tests for evaluating patients before and after their inclusion in exercise programs, as well as recommendations regarding a number of sports and physical activities. Even with the increased number of publications, there is still no general agreement with regard to these recommendations. Indeed, the participation of children suffering from rheumatic diseases is the best way for them to maintain a satisfactory range of motions, strength, power, and physical fitness and also to increase their self-esteem.

Objašnjeno je djelovanje i uloga pojedinih kemijskih glasnika za koje se uočilo se njihovo lučenje povećava pod utjecajem tjelesne aktivnosti, te da se na taj naèin utjeèe na dobro raspoloženje. Cilj ovog rada je objasniti na prihvatljiv način, jezikom razumljivim osobama koje se sportom bave iz rekreacije, fiziološke mehanizme i procese koje tjelesna aktivnost izaziva u organizmu s posebnim osvrtom na kemijske glasnike i hormone koji tom prilikom utječu na središnji živčani sustav. Posebno smo se osvrnuli na ulogu endorfina, te na način kojim njihovo otpuštanje prilikom tjelesne aktivnosti djeluje na promjene raspoloženja tj. stvaranje ovisnosti o vježbanju. U radu se prikazuje kako tjelesna aktivnost može imati i negativne učinke, te smo na kraju napravili sistematizaciju tjelesnih aktivnosti s obzirom na mogućnost stvaranja željenog pozitivnog psihičkog učinka. An overview of the research conducted as of this writing has been used to clarify the positive effects of physical activity on mood swings, as well as its application in alleviating symptoms of depression. The influence and role of individual chemical messengers have also been explained in these studies. Years of extensive research have suggested that the excretion of these messengers is enhanced by physical activity, which helps them to enhance moods. This paper places special emphasis on the role of endorphins and the effect of their excretion during physical activity on mood swings and on the development of exercise addiction. A short review also addresses the possible negative influence of physical activity, and a conclusion sets forth the categorization of various physical activities based on their potential ability to induce a desired positive influence on mental health.

Kod ženskih juniorki 75% prijeloma zamora bilo je kod klizačica koje nastupaju samostalno, 20.8% kod sportskih parova i 4.2% kod plesnih parova. Kod muških juniora 80% prijelomi zamora javilo se kod klizača koji samostalno nastupaju, 13.3% kod sportskih parova i 6.7% kod plesnih parova. Kod seniorki, 70.6% prijeloma zamora javilo se kod onih koje samostalno nastupaju, 23.5% kod sportskih parova i 5.9% kod plesnih parova, dok se kod seniora 80% prijeloma zamora javilo kod onih koji samostalno nastupaju, a 10% kod sportskih te plesnih parova. Bez obzira na disciplinu umjetnièkog klizanja, većina prijeloma zamora lokalizirana je na tibiji. Nije bilo razlike izmeðu pojave prijeloma zamora tijekom ljetnog i zimskog režima treniranja. Takoðer nije pronaðena korelacija izmeðu pojave prijeloma zamora i prehrambenih navika klizača. U žena nije pronaðena statistièčki značajna razlika izmeðu povećane učestalosti prijeloma zamora i menstrualnih neregularnosti. čimbenici koji najviše utječu na pojavu prijeloma zamora kod umjetnièkih klizača povezani su s povećanim fizièčkim naporima koji uključuju povećan broj rotacija i visinu kod pojedinog klizačkog skoka, povećanje količine napora tijekom pojedinog trenažnog procesa kao i povećan broj natjecanja tijekom jedne klizačke sezone. The relationship between the occurrence of stress fractures, training parameters and nutritional regimes was assessed using an anonymous retrospective questionnaire in elite international level figure skaters representing all 62 member federations of the International Skating Union. The response rate was 62% in female and 67% in male figure skaters. Results were obtained from both junior and senior figure skaters (245 females and 167 males) with a median age of 16 yrs. for females and 18 yrs. for males. With regard to the subjects, 41 females (16.7%) and 25 males (13.8%) reported stress fractures in the last years of training and competing in figure skating. In female junior skaters, 75% of the reported stress fractures occurred in singles, 20.8% in pairs, and 4.2% in ice dancers. Among male junior skaters, 80% of the reported stress fractures occurred in singles, 13.3% in pairs, and 6.7% in ice dancers. In senior females, 70.6% of the reported stress fractures occurred in singles, 23.5% in pairs, and 5.9% in ice dancers, while among male senior skaters, 80% of the reported stress fractures occurred in singles, with 10% in pairs and in ice dancers. Regardless of the discipline, the majority of all stress fractures were located in the tibial bone. There was no difference between the incidence of stress fractures during summer or winter training, and this incidence was in no way related to dietary habits. All figure skaters attributed the occurrence of stress fractures to changes in their training and competition programs. In women, there was no statistically significant increased incidence of stress fractures in those with menstrual irregularities. Important factors that appear to contribute to the occurrence of stress fractures in elite figure skaters are increased physiological demands, including increasing rotations and height of jumps, as well as more rigorous training and competitive schedules throughout the skating season.

SKIJAŠKO TRČANJE KAO REKREACIJSKA AKTIVNOST MLADIH NA ZIMOVANJU CROSS-COUNTRY SKIING AS A RECREATIONAL ACTIVITY OF YOUNG PEOPLE DURING WINTER LEISURE TIME Cigrovski, Vjekoslav; Kineziološki fakultet Sveučilišta u Zagrebu; vcigrovski@kif.hr Matković, Bojan; Kineziološki fakultet Sveučilišta u Zagrebu Matković, Branka R.; Kineziološki fakultet Sveučilišta u Zagrebu skijaško trčanje; navike bavljenja;zimskim sportovima; rekreacija;mladi cross-country skiing; snow sport habits; leisure; young people Skijaško trčanje kao rekreativna tjelesna aktivnost izuzetno je popularna u skandinavskim zemljama. Zbog povoljnog utjecaja na zdravlje i malog rizika ozljeðivanja skijaško trčanje primjenjivo je u svim dobnim skupinama. Primarni cilj istraživanja bila je procjena znanja i stavova mladih ljudi o skijaškom trčanju. U ovom istraživanju sudjelovalo je 180 učenika srednjih škola. Znanje ispitanika o skijaškom trčanju utvrðeno je putem upitnika, pomoću kojeg su dobiveni podatci o navikama mladih ljudi spram odlaska na zimovanje te participiranje u sportskim aktivnostima tijekom zimovanja. Upitnikom se posebno željelo utvrditi znanje ispitanika o skijaškom trčanju općenito, zatim o njegovom utjecaju na zdravlje, o zastupljenosti skijaškog trčanja u medijima te o mogućnostima bavljenja ovim sportom u Hrvatskoj. Postupak prikupljanja podataka bio je anoniman. Rezultati anketiranih ispitanika ukazuju da se na zimovanju najčešće bave alpskim skijanjem (59%), zatim sanjkanjem (16,6%), klizanjem (9,0%), daskanjem na snijegu (1.3%), dok se skijaškim trčanjem bavi svega 2.6% ispitanika. Zaključeno je kako skijaško trčanje nije sport koji srednjoškolci preferiraju, niti imaju saznanja o dobrobitima skijaškog trčanja na zdravlje. Isto tako ispitanici većinom smatraju skijaško trčanje monotonim i dosadnim sportom te time i neprimjerenim za rekreativno bavljenje. S obzirom da nemaju saznanja o mogućnostima bavljenja skijaškim trčanjem te pozitivnim učincima na zdravlje, smatraju da bi sport trebalo popularizirati putem medija. Konačno zaključeno je kako skijaško trčanje nije dovoljno atraktivna rekreacijska aktivnost za srednjoškolsku populaciju za razliku od dinamičnog i brzog alpskog skijanja koje je prema ovom istraživanju najzastupljenija rekreativna aktivnost na zimovanju. Cross-country skiing ranks as one of the most popular recreational activities in Scandinavian countries. Due to its highly beneficial effects on human health and low risk of injury, the sport may be practiced by people of all ages. This study involved 180 participants, all of whom were high school students, and its primary goal was to evaluate the knowledge and attitudes towards crosscountry skiing among young people. The participants' knowledge of cross-country skiing and leisure habits were collected using a questionnaire. The respondents' identities remained anonymous as the questionnaire was administered and collected. Emphasis was placed on a general knowledge of cross-country skiing, an understanding of the beneficial effects that it has on health, the attention that cross-country skiing attracts via the media, and, finally, possible opportunities for practicing cross-country skiing in Croatia. The Results indicated that the most popular winter leisure activities are alpine skiing (59%), sledding (16.6%), skating (9.0%), and snowboarding (1.3%), and that only 2.6% of study participants practice cross-country skiing. It was concluded that cross-country skiing is a favorite sport among high school students and that their knowledge of the health benefits of this activity is poor. The study found that students generally consider cross-country skiing to be boring and unsuitable as a recreational activity. As young peoples' knowledge of cross-country skiing, especially its health benefits, is inadequate, perhaps better media coverage of the sport is needed. Finally, it seems that the lack of popularity of cross-country skiing among the young people included in this investigation is in stark contrast to their enthusiasm for alpine skiing, a more dynamic recreational activity.

POVEZANOST IZMEÐU NEKIH PSIHOLOŠKIH KARAKTERISTIKA I SPORTSKE IZVEDBE KOD VRHUNSKIH MLADIH KUGLAČA THE RELATIONSHIP BETWEEN SOME PSYCHOLOGICAL CHARACTERISTICS AND SPORT PERFORMANCE OF ELITE YOUNG BOWLING ATHLETES Sindik, Joško; Kindergarten Trnoružica, Zagreb, Croatia; josko.sindik@zg.t-com.hr kuglači; konativne karakteristike; rezultat, povezanost bowling players; conative characteristics; result; correlation Na temelju odabira konativnih karakteristika potencijalno bitnih za uspjeh u većem broju kinezioloških aktivnosti, utvrðen je odnos (relacije) izmeðu odabranih teorijskih koncepta koji opisuju karakteristike ličnosti kuglača, te varijabli koje su pokazatelji rezultatskog uspjeha kuglača u natjecanju, tj. dovedene su u vezu konativne karakteristike potencijalno bitne za uspjeh u kuglanju, s natjecateljskim učinkom kuglača. Pretpostavljena je značajna povezanost konativnih karakteristika i uspjeha u kuglanju. Populacija iz koje je uzorak izabran je cjelokupni širi krug kandidata za mladu reprezentaciju Hrvatske (N=24; 11 kuglačica i 13 kuglača, u dobi od 15 do 23). Oni su bili ispitani s instrumentima za mjerenje konstrukata mentalne čvrstoće, perfekcionizma, lokusa kontrole, motivacije za postignućem, agresivnosti, ciljne orijentacije te natjecateljske anksioznosti. Rezultati su pokazali da postoji odreðen broj značajnih korelacija konativnih obilježja i sportskog uspjeha, na temelju kojih se može sugerirati postupke za diferencirani psihološki pristup pojedincima, tijekom trenažnog rada. Manji broj značajnih povezanosti može se tumaèiti ujednačenošću konativnih karakteristika vrhunskih kuglača. Hipoteza je samo djelomično potvrðena. On the basis of selection of conative characteristics that are potentially significant for success in a large number of kinesiologic activities, the relations between chosen theoretic constructs that describe the personality of bowling players and variables that describe the success in bowling championship have been ascertained. In other words, conative characteristics potentially important for success in bowling are correlated with the success in bowling competition. Significant correlation between conative characteristics and success in bowling was hypothesized. Population from which the intentional sample is chosen is initially selected narrow circle of candidates for the Croatian junior team (N=24; 11 female and 13 male bowling players, aged from 15 to 23).They were examined with instruments that measure constructs of hardiness, perfectionism, locus of control, motivation for achievement, aggressiveness, goal orientation and competitive anxiety. Results have shown that there are certain significant correlations between conative characteristics and sport success, on the basis of which it is possible to suggest the procedures for a differentiated psychological approach to individuals, during training period. A relatively small number of significant correlations, can be explained with similarity of conative characteristics of the elite bowling players. The hypothesis could be only partially confirmed.

Energija koja se u organizmu dobiva iz metabolitičkih procesa koristi se protiv entropije, a preostali dio energije oslobaða se u vidu topline. Ljudski organizam može optimalno funkcionirati ukoliko se njegova unutrašnja temperatura ne mjenja za više od 0,5 °C. Temperaturu tijela nadziru složeni termoregulacijski kontrolni mehanizmi. Organizam sportaša je izložen dodatnom stvaranju metaboličke topline zbog mišične aktivnosti ali i preuzimanju topline iz okoline. U ovom radu se iznose specifične značajke adaptacije organizma tijekom tjelesne aktivnosti u toplim uvjetima okoline, te se obrazlažu metode prevencije i terapije patoloških stanja kao što je toplinska bolest koja može ugroziti ne samo vrhunski rezultat nego i zdravlje sportaša. A high number of competitions, as well as many training hours spent in an environment characterized by hot temperatures, require athletes performing various sports to have adapted extensively to heat. Metabolic energy produced during physical activity is used against entropy, while excess energy is released from the body as heat. Body temperature is controlled by thermoregulatory mechanisms. The human body can remain at an optimal level of performance as long as the core temperature is maintained within limits of ±0.5°C. The athlete's body is exposed to additional metabolic heat because of physical activity, and also to additional heat coming from external sources. This paper deals with the following topics: (1) the specific heat adaptation process undergone by athletes practicing their sport in hot environments, and (2) prevention and treatment of heat illness and heat stroke, which could not only compromise performance, but may also endanger the athletes' health and, in some instances, be life threatening.

IZNENADNA SMRT TIJEKOM I NEPOSREDNO NAKON SPORTSKE AKTIVNOSTI SUDDEN DEATH DURING AND IMMEDIATELY AFTER PHYSICAL ACTIVITY Nabršnigg, Katarina; Kineziološki Fakultet, Sveučilište u Zagrebu Janković, Saša; Kineziološki Fakultet, Sveučilište u Zagrebu Kniaz, Damir; Kineziološki Fakultet, Sveučilište u Zagrebu; damir.knjaz@kif.hr kardiovaskularne bolesti; tjelesna aktivnost; sportaš; iznenadna srčana smrt cardiovascular disease; physical activity; athlete; sudden cardiac death Iznenadna smrt profesionalnih sportaša ili rekreativca za vrijeme treninga, natjecanja ili neposredno nakon, rijedak je događaj, ali prisutan. Kada se dogodi izaziva veliki interes javnosti. Podaci o incidenciji iznenadne smrti sportaša znatno variraju od studije do studije (s obzirom na sredinu, dob, spol, vrstu sporta, definiranje iznenadne smrti i način prikupljanja podataka), ali možemo reći da incidencija iznosi aproksimativno 1:100 000 godišnje. Najčešći razlozi potencijalnih incidenata tijekom tjelovježbe su kardiovaskularni. Kod sportaša mlađih od 30-35 godina uzrok iznenadne smrti su najčešće različite kongenitalne kardiovaskularne bolesti (kardiomiopatija, aritmogena displazija desnog ventrikula, anomalije koronarnih arterija i dr.) ne otkrivene prije početka bavljenja sportom. Kod tjelesno aktivnih pojedinaca starijih od 35 godina uzrok iznenadne smrti su uglavnom aterosklerotične promjene koronarnih arterija s njihovim komplikacijama (infarkt miokarda, fibrilacija ventrikula, srèani arest). Posebnu pozornost potrebno je usmjeriti prvenstveno na prevenciju iznenadne smrti te na spašavanje života provođenjem kardiopulmonalne reanimacije. U prevenciji je istaknuta uloga sistematskih pregleda jer upravo redoviti, temeljiti i usmjereni sistematski pregledi te pravovremeno otkrivanje srčanih bolesti mogu spasiti život sportaša. Sudden cardiac death in athletes is an uncommon but extremely noticable event because of the high profile of amateur and professional athletes and expected excellent health of these athletes. Fortunately, sudden death in an athlete, especially a young athlete, is a rare event. Estimates vary greatly depending on the age of the athlete, the source of the sampling population, the sports activity and the definition of sudden death. One study estimated the incidence of sudden death during exercise as one death per 100,000 athletes per year. Congenital cardiovascular disease is the leading cause of nontraumatic sudden death in athletes younger than 30 years, such as cardiomyopathy, arrhythmogenic right ventricular dysplasia, coronary anomalies etc. In the older athletes, sudden death is generally due to arrhythmias in the context of coronary artery disease. Primarily, we should pay attention to the preventive measures such as systematic examinations and also to the resuscitation of the athletes after cardiac arrest. Early identification and disqualification of athletes affected by some cardiovascular disease at screening before participation in sports activity may have prevented sudden cardiac death.

ZNANJE TRENERA O HIDRACIJI SPORTS COACHES' KNOWLEDGE ABOUT HYDRATION hidracija; rehidracija; sportski trener hydration; rehydration; sport coach Tjelesne tekućine i ravnoteža elektrolita esencijalni su segmenti optimalne fiziološke funkcije organizma. Tijekom tjelesne aktivnosti, fizičkog rada ili uslijed izloženosti povišenoj temperaturi, može se razviti izvjestan stupanj dehidracije, te dolazi do promjene omjera intracelularne i ekstracelularne tekućine. Cilj ovoga rada bio je utvrditi znanje sportskih trenera o hidraciji. Istraživanje je provedeno na uzorku od 170 sportskih trenera različitih sportova. Najmlađi ispitanik imao je 17, a najstariji 55 godina, dok je prosjek bio 27,5 godina. Ispitivanje je provedeno pomoæu ankete. Rezultati ovog istraživanja obrađeni su programskim paketom STATISTICA FOR WINDOWS, VER 6.0 na Kineziološkom fakultetu u Zagrebu. Korištene su metode osnovne deskriptivne statistike, te su izraèunate aritmetičke sredine i standardne devijacije za dob, dok su za ostale varijable izračunate frekvencije. Sagledavajući rezultate u cjelini može se zaključiti da sportski treneri imaju nedostatno znanje o hidraciji. Naravno da znaju da je hidracija neizostavan dio treninga i natjecanja i da je tekuæinu potrebno uzimati i prije i za vrijeme treninga i natjecanja kao i poslije. Ne znaju da žeđ nije adekvatan pokazatelj gubitka tekućine, no s druge strane znaju da količinu izgubljene tekućine mogu jednostavno odrediti vaganjem sportaša prije i poslije tjelesne aktivnosti. Zabrinjava podatak da značajna većina sportskih trenera ne zna koliko štete dehidracija može izazvati ako se pojavi za vrijeme treninga ili natjecanja te da i prekomjeran unos tekućine može uvjetovati zdravstvene probleme. Također gotovo dvije trećine trenera pokazuje da ne zna kako alkoholna pića nisu dobro sredstvo za rehidraciju. Body fluids and electrolyte balance are the essential parts of optimal physiological function of human body. Physical exercise and sport can produce dehydration and changes in relationship between intra and extra cellular fluids. The aim of this paper was to examine the knowledge about hydration in sport coaches. The sample consisted of 170 sports coaches from different sports (mean age 27,5 years, range 17-55). A questionnaire was constructed and filled in by the coaches anonymously. Basic descriptive statistical parameters were calculated. The results pointed to the fact that the knowledge about hydration of sports caches in Croatia is not on adequate level. They know that hydration is the important part of training and competition and that athlete have to take fluids before, during and after training/competition. Coaches do not know that thirst is not good sign of dehydration, but they know that by weighting before and after the exercise fluid loss can be estimated. Concerning data is that coaches have no knowledge about damage that can be produced by dehydration. Also, very disturbing finding is that coaches think alcohol beverages can help in re-hydration.

POVEZANOST RAVNOTEŽE S PROCESOM USVAJANJA SKIJAŠKOG ZNANJA CORRELATION BETWEEN BALANCE AND LEARNING OF ALPINE SKIING Cigrovski, Vjekoslav; Kineziološki Fakultet Sveučilišta u Zagrebu Matković, Bojan Prlenda, Nikola ravnoteža; proces učenja; skijaški početnici balance; learning process; ski beginners Visoko razvijena razina motoričke sposobnosti ravnoteže utječe na uspjeh natjecatelja u alpskom skijanju te ima važnu ulogu u prevenciji od ozljeđivanja alpskih skijaša. Cilj ovog istraživanja bio je utvrditi povezanost različitih testova za procjenu ravnoteže s procesom usvajanja znanja kod skijaških početnika. Ravnoteža je na 119 skijaških početnika procijenjena pomoću tri statička testa, dok je za utvrđivanje razine stečenog skijaškog znanja kod ispitanika odabrano pet elemenata skijaške tehnike: spust koso, zavoj k brijegu, plužni zavoj, osnovni zavoj te vijuganje. Korelacijska analiza pokazala je povezanost rezultata u testu vodoravni ravnotežni položaj raskoračno na platformi sa svih pet testova za procjenu skijaškog znanja (r=0.22; r=0.25; r=0.20; r=0.19 i r=0.20). Povezanost sa četiri testa za procjenu skijaškog znanja (zavoj k brijegu, plužni zavoj, osnovni zavoj te vijuganje) utvrđena je kod testa ravnotežni položaj raskoraèno na obostranoj platformi (r=0.19; r=0.24; r=0.28 i r=0.20), a povezanost s tri testa za procjenu skijaškog znanja (zavoj k brijegu, plužni zavoj te osnovni zavoj) pokazana je kod testa okomiti ravnotežni položaj raskoračno na platformi (r=0.17; r=0.22 i r=0.17). Analiza rezultata pokazala je da većina skijaških početnika koji su ostvarili dobre rezultate u testovima za procjenu ravnoteže, ostvaruje i visoke ocjene u testovima za procjenu skijaškog znanja i obrnuto. Developed motor ability balance contributes to success of professional alpine skiers and moreover has an important role in injury prevention. The aim of this research was to investigate the correlation of different laboratory balance tests with success of alpine ski learning in ski beginners. Balance was tested in 119 alpine ski beginners with three laboratory balance tests, and the level of obtained ski knowledge was assessed on five chosen elements of ski technique: traversing, uphill turn, snow plough turn, basic turn and short turn. Significant correlation was obtained between results in lateral tilt test on plywood balance board and all five elements of alpine ski technique (r=0.22; r=0.25; r=0.20; r=0.19 and r=0.20). Moreover results were significant between four tests used to evaluate alpine ski knowledge (uphill turn, snow plough turn, basic turn and short turn) and balance test on both-side used balance board (r=0.19; r=0.24; r=0.28 and r=0.20), as well as between uphill turn, snow plough turn and basic turn and front-back tilt test on balance board (r=0.17; r=0.22 and r=0.17). To conclude, our results show that participants doing better on balance tests achieve better results in learning alpine ski technique and vice versa.

Izmjereno je 113 ispitanica, studentica Kineziološkog fakulteta, Sveučilišta u Zagrebu baterijom od 15 motorièkih testova i 4 antropometrijske mjere. Uspješnost izvođenja društvenih plesova procijenila su tri kompetentna stručnjaka. Regresijskom analizom utvrđene su statistički značajne multiple korelacije prediktorskog skupa varijabli s 4 kriterijske varijable (D1, D3, D4 i D5), što nije bio sluèaj s drugom kriterijskom varijablom (D2). Povezanost plesne uspješnosti i motoričkog prostora definirana je prediktorima: koraci u stranu s okretom za 360° (MAGKUS360) koordinacija i skok u vis s mjesta (MFESVM) eksplozivna snaga. Povezanost plesne uspješnosti i morfoloških obilježja definirana je tjelesnom masom (MT) i ukupnom količinom tjelesne masti (KG/MASTI). The aim of this study was to determine the relationship between motor abilities and anthropometric characteristics, and dance performance. By determining these relationships one could predict dance performance. A total of 113 female kinesiology students were examined using 15 tests aimed to measure motor abilities and 4 tests aimed to measure anthropometric characteristics. Dance performance was evaluated by three independent experts. Regression analysis revealed significant correlations between independent and 4 dependent variables (D1, D3, D4 and D5), while no correlations were observed between D2 dependent variable and the set of independent variables. The relationship between dance performance and motor abilities is defined by the variables (1) side steps with 360o turn (MAGKUS360), and (2) standing high jump (MFESVM). The relationships between dance performance and anthropometric characteristics is defined by the variables (1) body mass (MT), and total fat mass (KG/MASTI).

TJELESNA AKTIVNOST U HLADNIM UVJETIMA OKOLINE I PREVENCIJA HIPOTERMIJE PHYSICAL ACTIVITY IN COLD ENVIRONMENT AND ITS RELATION AND PREVENTION OF HYPOTHERMIA Legović, Dalen; Klinika za ortopediju Lovran, Sveučilište u Rijeci; dalen.legovic@gmail.com Gulan, Gordan; Klinika za ortopediju Lovran, Sveučilište u Rijeci Tudor, Anton; Klinika za ortopediju Lovran, Sveučilište u Rijeci Šantić, Veljko; Klinika za ortopediju Lovran, Sveučilište u Rijeci Jurdana, Hari; Klinika za ortopediju Lovran, Sveučilište u Rijeci Prpić, Tomislav; Klinika za ortopediju Lovran, Sveučilište u Rijeci Šestan, Branko; Klinika za ortopediju Lovran, Sveučilište u Rijeci regulacija tjelesne temperature; hipotermija; zimska odjeća thermoregulation; hypothermia; cold -weather clothing Kontrolni mehanizmi koji nadziru temperaturu tijela, složeni su i nastoje da se unutarnja fiziološka temperatura tijela ne mijenja u većem rasponu od 0,5 oC . Ukoliko se temperatura tijela ne održi, mjereno rektalno iznad 32°C , dolazi do progresivnog usporavanja svih fizioloških procesa. Rizik od hipotermije dodatno se povećava u slučaju nedostatka znanja o mogućim tegobama i komplikacijama koje prate ovo stanje, što je u sportaša naročito izraženo, pri nedostatku komunikacije s ostalim sudionicima takmičenja ili trenerom. Nedovoljna psihološka i fizička priprema, potiskivanje znakova iscrpljenosti i neadekvatna zaštita od vremenskih nepogoda doprinose pogoršanju rezultata u hladnim uvjetima, pa i opasnošću od ozbiljnog narušavanja zdravlja. Iznosimo zato mjere prevencije hipotermije kao i postupke zagrijavanja, s osvrtom na ulogu odjeće u hladnim uvjetima. Body temperature is controlled by complex thermoregulatory mechanisms which maintain core body temperature within 0, 5 o C. Lowering rectal temperature below 32o C significantly decreases level of human body performance. Due to the lack of knowledge about first symptoms and usually poor communication with other competitors, athletes are prone to hypothermia and its complications. Insufficient protection from cold combined with poor physical and psychological fitness can further endanger athletes' health. This paper presents measures of prevention of hypothermia and warming-up procedures with special attention paid to clothing in cold conditions.

SPECIFIČNOSTI PLIOMETRIJSKOG TRENINGA TENISAČA PLYOMETRIC TRAINING SPECIFICS IN TENNIS Čanaki, Martina; Kineziološki fakultet Sveučilišta u Zagrebu; mcanaki@kif.hr Birkić, Željko; Kineziološki fakultet Sveučilišta u Zagrebu tenis; pliometrija; kretanja tennis; plyometrics; footwork Tenis je kompleksna sportska aktivnost obilježava velik broj različitih tehnika kretanja koje se pretežno izvode maksimalnom brzinom u dugom vremenskom razdoblju. Kretanja se sastoje od ponovljenih startova, ubrzanja i usporavanja, te brzih promjena pravca kretanja od kojih su ishod udarca i taktička komponenta u direktnoj zavisnosti. Iz navedenog razloga najvažnije i najviše zastupljene motoričke sposobnosti su upravo startna brzina i ubrzanje te brza promjena pravca kretanja. Metoda pliometrije jedna je od najučinkovitijih metoda za razvoj različitih tipova eksplozivne snage u obliku treninga u kojem dolazi do ekscentrično - koncentričnog rada mišića. U ovom radu se iznose osnovne značajke potrebne za provedbu treninga eksplozivne snage tipa pliometrije. Važne informacije o anatomsko i fiziološkim obilježjima, isto kao i o konceptima mišićnih kontrakcija prisutnih tijekom pliometrijskog treninga često su nepoznate ili manje važne za provedbu programa pliometrijskog treninga. Osnovne odrednice i upute pri provedbi pliometrijskog trenažnog procesa nadovezuju se na anatomsko-fiziološku informacijsku komponentu. Najzanimljivije odrednice pliometrijskog trenažnog procesa su osnovna obilježja programa, učestalost, volumen i intenzitet. Za sigurnu i kvalitetnu provedbu treninga da bi se smanjio stupanj rizika od ozljede i usvojila izvedba pliometrijskih vježbi, tenisač se mora prvo podvrgnuti testiranju s ciljem utvrđivanja potrebite razine kondicijske pripremljenosti. Tennis is categorized as a complex sporting activity. It is characterised by a large number of different techniques of movement that are mostly performed by maximum speed in a long period of time. Movements consist of re-starting, acceleration and slowing down and rapid changes of direction, of which the outcome of the stroke and the tactical component are in direct dependencies. For this reason the most important and most represented motor skills are starting speed and acceleration as well as quick change of direction. Plyometric method is one of the most effective methods for developing different types of explosive power using eccentric - concentric muscle work. This paper presents the basic features necessary for the implementation of explosive power training-plyometric type. Important information about the anatomic and physiological features, as well as concepts of muscle contraction during plyometric training are often unknown or less important for the implementation of the plyometric training. General guidelines and instructions rely on the anatomicphysiological component of the information when implementing plyometric training. The most interesting provisions of plyometric training processes are the basic features of the program, frequency, volume and intensity. For safe and efficient implementation of training, tennis player must first be subjected to exercise performance testing.

DVADESET GODINA IZLAŽENJA HRVATSKOG ŠPORTSKOMEDICINSKOG VJESNIKA Pećina, Marko Hrvatski športskomedicinski vjesnik Imam osjećaj da je to bilo jučer kad sam u svojstvu glavnog urednika pisao svečani uvodnik povodom "Deset godina izlaženja Hrvatskog športskomedicinskog vjesnika" i da je to bilo nedavno kada smo istim povodom održali skromnu proslavu u Starogradskoj vijećnici na Gornjem gradu u Zagrebu i kada smo objavili Predmetno kazalo i Autorsko kazalo za cjelokupno desetgodišnje razdoblje izlaženja časopisa. Međutim, ponosan sam i sretan da eto sada u svojstvu predsjednika Savjeta časopisa pišem svečani uvodnik povodom daljih deset godina izlaženja našeg časopisa. Hrvatski športskomedicinski vjesnik (HŠMV) je glasilo Hrvatskog olimpijskog odbora (HOO), a počeo je izlaziti prije 20 godina kao Košarkaški medicinski vjesnik - glasilo Košarkaškog saveza Hrvatske. Predsjednik Savjeta časopisa bio je prof. dr. sc. Radovan Medved, glavni i odgovorni urednik prof. dr. sc. Marko Pećina, a zamjenik glavnog urednika Mr. sc. Ivo Vidović, dr.med., da bi prije dvije godine došlo do djelomičnog pomlađivanja vodstva časopisa i predsjednik Savjeta je postao prof. dr. sc. Marko Pećina, glavni i odgovorni urednik prof. dr. sc. Branka Matković, zamjenik glavnog urednika ostaje i dalje vječno mladi Mr.sc. Ivo Vidović, dr. med., a urednici su prof. dr. sc. Miroslav Hašpl, doc. dr. sc. Saša Janković i dr. sc. Lana Ružić. Također, vjerni suradnik časopisa je i naš tehnički urednik gospodin Marijan Kramar kojem dugujemo zahvalnost za tehničku kvalitetu našeg časopisa već dugi niz godina. Hrvatski športskomedicinski vjesnik je znanstveno-stručni časopis koji je dosegao zavidnu razinu i koji eto ustrajno već dva desetljeća širi spoznaje iz područja športske medicine i promovira dosege naših autora iz tog područja. O uloženom trudu uredništva časopisa i autora priloga u časopisu najbolje se može suditi iz Tablice 1 u kojoj je prikazan pregled objavljenih radova prema vrsti (uključujući i ovaj prvi broj godišta 20, godine 2005.). Tablica 1. Pregled objavljenih radova prema vrsti od 1986-2005 Table 1. Review of published papers in period 1986- 2005. Izvorni znanstveni članak Scientific article 114 Pregled (Kreitički) Review (Critical) 46 Stručni članak Proffessional paper 78 I povodom ove značajne obljetnice objavit ćemo u broju 2 godišta 20, godine 2005. Predmetno i Autorsko kazalo iz kojeg će biti vidljivo sadržajno bogatstvo i raznolikost znanstvenih i stručnih priloga objavljenih tijekom ovih 2o godina izlaženja časopisa, a koji prilozi pokrivaju cjelokupno područje športske medicine i to od fiziologije, antropologije, kineziologije, kliničke farmakologije i dopinga, prehrane i športske traumatologije. Završit ću ovaj kratki uvodnik priznanjem koje smo dobili od našeg doajena prof. dr. sc. Radovana Medveda, koji nam je napisao:" Odajući priznanje redakciji časopisa, koji u sadašnjem trenutku predstavlja jedinu "svijetlu točku" sportske medicine u Hrvatskoj, i posebno Vama, na korisno uloženom velikom trudu ostajem sa štovanjem". Zahvalni smo našem doajenu na trudu koji je uložio među inim i u ovaj časopis, ali ne smijemo zaspati na lovorikama i trebamo težiti da se korist našeg časopisa osjeti na što širem području i u tom smislu pozdravljam napor uredništva da ovo bude prvi broj časopisa koji će biti dostupan i u elektronskom mediju. U ovom svečanom uvodniku ne smijemo zaboraviti potporu HOO-a koja nije izostala od prvog predsjednika gospodina Antuna Vrdoljaka do današnjeg predsjednika gospodina Zlatka Mateše i svih dosadašnjih generalnih tajnika i praktično svih dužnosnika na različitim razinama administracije HOO-a na čemu im najljepše zahvaljujemo. Završit ću ovaj uvodnik još jednim citatom "Bez pisane riječi struka je mrtva".

OROFACIJALNE OZLJEDE U VATERPOLU OROFACIAL INJURIES IN WATER - POLO OROFACIAL INJURIES IN WATER - POLO Seifert, Davor; School of Dental Medicine, University of Zagreb, Zagreb, Croatia Jerolimov, Vjekoslav; Stomatološki fakultet Sveučilišta u Zagrebu Bojčić, Dario; Privatna stomatološka ordinacija, Split orofacijalne ozljede;vaterpolo orofacial injuries;water-polo Vaterpolo je iznimno naporan i zahtjevan šport, a u Hrvatskoj uživa veliku popularnost. Koristeći metodu upitnika provedeno je istraživanje broja, vrste i težine ozljeda kod 121 igrača 1. Hrvatske vaterpolske lige. Prosječno vrijeme treniranja vaterpola bilo je 11,77, a nastupanja u 1. vaterpolskoj ligi 5,55 godina. Igrači su prijavili 1034 ozljede tijekom karijere, prosječno 1,54 ozljede po igraču godišnje. Orofacijalne ozljede čine 74,02% ozljeda, a od toga 39,45% čine ozljede usana. Najviše orofacijalnih ozljeda zadobivaju centri, zatim bekovi, pa napadači a najmanje vratari. Prevalencija ozljeda je visoka, ali uglavnom nisu ozbiljnije prirode. Ozljede koje su razmjerno lagane i ne zahtijevaju, osim iznimno, veće liječničke intervencije, djeluju destimulativno na korištenje zaštitnih sredstava – interedentalnih štitnika. Većina ozljeda mogla se spriječiti, ili barem ublažiti, korištenjem štitnika. Korištenje štitnika je preporučljivo, kao i osiguranje opreme za pružanje pomoći na samom bazenu, naravno, uz nazočnost stomatologa tijekom vaterpolskih utakmica. Water-polo is a very difficult and demanding sport, and very popular in Croatia. Investigation on number, type and severity of injuries during water-polo was conducted on 121 Croatian 1st Division water-polo players using questionnaires. Average years of training were 11,77, and average time playing in 1st division 5,55 years. Total amount of injuries was 1034 during career, and mean number of injuries was 1,54 per player annually. Orofacial injuries comprise 74,02% of all injuries. Among them 39,45% were bruises and cuts of lips. Most orofacial injuries are experienced by pivots, than guards, followed by forwards and least by goalkeepers. The prevalence of injuries is high, but mostly injuries are not severe. Light injuries, healed without therapy or only exceptionally cured after minor medical treatment is not stimulating for mouthguard use. Most of injuries were preventable or can be diminished with use of mouthguards. The use of mouthguards is recommended but not mandatory, as well as the maintenance of equipment and dentist well educated in treatment of orofacial injuries during water polo matches.

RETROSPEKTIVNO ISTRAŽIVANJE O UČESTALOSTI OZLJEDA STUDENATA KINEZIOLOŠKOG FAKULTETA RETROSPECTIVE ANALYSIS OF INJURY INCIDENCE IN STUDENTS OF KINESIOLOGY Trošt, Tatjana; Faculty of Kinesiology, University of Zagreb, Croatia Ružić, Lana; Faculty of Kinesiology, University of Zagreb, Croatia; lana.ruzic@kif.hr Janković, Saša; Faculty of Kinesiology, University of Zagreb, Croatia ozljede;studenti;Kineziološki fakultet injuries;students;Faculty of Kinesiology Cilj ovog rada bio je utvrditi u kojim uvjetima i na kojim kolegijima se studenti Kineziološkog fakulteta najčešće ozljeđuju, gdje su ozljede najčešće locirane, koji tip ozljeda prevladava i u kojoj mjeri ozljede utječu na kontinuiranost školovanja. Istraživanje je provedeno na uzorku od 105 studenata (48 studentica i 57 studenata) Kineziološkog fakulteta Sveučilišta u Zagrebu na kraju osmog semestra. Studenti su ispunili posebni anketni listić. Rezultati su pokazali da se studenti prosječno ozljeđuju 1.01 puta za vrijeme trajanja studija. Predmeti na kojima su ozljede bile najčešće su sportska gimnastika, judo i hrvanje. Također je zabilježen veliki broj ozljeda koje su se desile za vrijeme treninga izvan fakultetskih obveza, naročito kod vrhunskih sportaša. Studenti su se češće ozljeđivali od studentica. Studentice su najčešće ozljeđivale potkoljenicu i stopalo, a studenti rameni zglob. Najčešći tip ozljede bila je ozljeda mekog tkiva tj. vezivnog tkiva, naročito ligamenata. Oko pola studenata koji su pretrpjeli ozljedu nije imalo problema pri polaganju i pripremanju ispita. Ipak, 25.76% ozlijeđenih studenata trebalo je pauzirati jednu, a 4.55% dvije godine studija zbog posljedica. The aim of the study was to determine in which conditions and during which classes do students of the Faculty of Kinesiology injure themselves. It was also important to find out the most common location of the injuries, the most frequent type of injuries and the effects of these on the continuity of the studies. The sample of comprised 105 examinees (48 female and 57 male), all students of the Faculty of Kinesiology, University of Zagreb. They were at the end of the last year of studies. The examinees filled up a questionnaire. The average number of injures was 1.01 injury per student during the study. Artistic gymnastic, wrestling and judo had a very high injury rate, followed by the injuries that had occurred during training in free time. Male students had a highest injury rate then the female students. The most frequently injured areas of the body for female were the lower leg and the foot, while men were more prone to shoulder injuries. Ligament lesions were the most frequent. Many injuries did not affect the continuity of the study, however 25.76% of the injured students were forced to miss one year, and 4.55% two years of the programme.

MORFOLOŠKE I SOMATOTIPSKE KARAKTERISTIKE VRHUNSKIH HRVATSKIH VESLAČA MORPHOLOGICAL CHARACTERISTICS AND SOMATOTYPE OF ELITE CROATIAN ROWERS Mikulić, Pavle; Faculty of Kinesiology, University of Zagreb, Croatia Vučetić, Vlatko; Faculty of Kinesiology, University of Zagreb, Croatia Matković, Branka; Faculty of Kinesiology, University of Zagreb, Croatia Oreb, Goran; Faculty of Kinesiology, University of Zagreb, Croatia veslanje;morfološke karakteristike;somatotip rowing;morphological characteristics;rowing Cilj rada bio je na uzorku 29 najboljih hrvatskih veslača utvrditi neke morfološke karakteristike, utvrditi sastav tijela obzirom na odnos masne i nemasne komponente, odrediti somatotipske karakteristike te analizirati razlike u prostoru morfoloških karakteristika između seniora «A» (dob ≥23) te seniora «B» (dob <23). Sastav tijela određen je mjerenjem 7 kožnih nabora po Jacksonu i Pollocku, a prema uputama IBP-a izmjerene su: visina i masa tijela, raspon ruku, dužina noge, ruke, šake i stopala, biakromijalni i bikristalni raspon, dijametri lakta, ručnog zgloba i koljena te opsezi nadlaktice, podlaktice, grudi, trbuha, natkoljenice i potkoljenice. Somatotip je određen metodom Heath i Cartera temeljenoj na Sheldonovoj klasifikaciji tipova. Rezultati su pokazali da su hrvatski veslači znatno viši i teži od normalne populacije, a podjednaki u usporedbi sa veslačima drugih zemalja. Potkožno masno tkivo manje je razvijeno, a cirkularne dimenzije tijela veće su od onih dobivenih u populaciji nesportaša. To se javlja kao rezultat specifičnog treninga i voluminoznosti tijela veslača. Somatotipske karakteristike ukazuju na posebno razvijenu mezomorfnu komponentu, druga je endomorfna, a ektomorfna komponenta najslabije je razvijena. Tjelesna visina i raspon ruku jedine su dimenzije u kojima su se dvije podskupine ispitanika razlikovale statistički značajno i to u korist «A» seniora. The aim of this study was to determine some morphological characteristics, to determine the body composition with regard to subcutaneous fat tissue vs. lean body mass ratio, determine the somatotype as well as analyze the differences in the area of morphological characteristics between «A» (age ≥23) and «B» seniors (age <23). The sample consisted of 29 best Croatian rowers. Body composition was determined by measuring 7 skin fold measurements according to Jackson an Pollock, and according to IBP recommendations the following dimensions were measured: body height and weight, arm reach, leg, arm, fist and foot length, biacromial and bicristal range, diameters of elbow, wrist and knee as well as the girth of leg, arm, fist and foot. Somatotype was determined by Heath & Carter method based on Sheldon's classification. Results indicated that Croatian rowers are significantly heavier and taller than normal population, and similar when compared to other international rowers. Subcutaneous fat tissue is less developed, and girth dimensions are larger than those find in non athletes. That is a result of rowers' specific training as well as voluminosity of rowers' body. Somatotype indicated especially developed mezomorphic component followed by endomorphic component, with ectomorphic component being the least developed. Body height and arm reach were the only dimensions in which the two observed groups of examinees produced statistically significant differences (with «A» seniors achieving larger dimensions).

BIOMEHANIČKA ANALIZA SMEČA IZ PREDNJE I STRAŽNJE ZONE U ODBOJCI L KINEMATICAL ANALYSIS OF THE FRONT AND BACK ZONE SPIKE IN VOLLEYBALL Đurković, Tomislav; Faculty of Kinesiology, University of Zagreb, Croatia Marelić, Nenad; Faculty of Kinesiology, University of Zagreb, Croatia Hraski, Željko; Faculty of Kinesiology, University of Zagreb, Croatia; zhraski@kif.hr Šikanja, Ljiljana; Faculty of Kinesiology, University of Zagreb, Croatia biomehanika;kinematika;odbojka;smeč biomechanics;kinematics;volleyball;spike U današnjoj modernoj odbojci smeč iz stražnje zone, kao element napada zauzeo je važno mjesto. Osim atraktivnosti igre zaslužan je i za raznolikost u napadu. Namjera rada bila je da se napravi usporedna analiza dviju osnovnih tehnika smeča s mreže i iz stražnje zone (druge linije), izvedenih od članova nacionalne odbojkaške vrste. Snimanje je izvršeno dvjema video kamerama, frekvencije od 60 slika u sekundi. Digitaliziranje i procesiranje podataka izvršeno je prema standardnoj APAS proceduri. Dobiveni rezultati opravdavaju tendenciju povećanja napada iz stražnje zone te omogućuju trenerima objektivniju sliku o razlikama ovih dviju vrsta smečeva. In volleyball today, spike is becoming more and more important as a attack element. It makes the game more exciting and adds to a variety of attack moves. The aim of this thesis is to make a comparative analysis of two basic techniques: spike from the net and back row spike, performed by a National Volleyball League Player. Two cameras recorded the spikes, with a frequency of 60 shots per second. Dana was digitalised and processed in accordance with the APAS standard procedure. The obtained results justify the tendency to increase the back row attack and give the coaches a clearer picture of the difference between the two spikes.

RAZLIKE U INTERESIMA I STAVOVIMA O SADRŽAJU PREDMETA TJELESNE I ZRAVSTVENE KULTURE (TZK) U ODNOSU NA ŠKOLSKI USPJEH STUDENTS' INTERESTS AND ATTITUDES IN RELATION TO PE-ACTIVITIES AND TO GENERAL ACHIEVEMENT AT SCHOOL Runjić, Katarina; Učiteljska akademija Sveučilišta u Zagrebu interesi;sadržaji TZK;uspjeh interests;PE activities;school achievement Cilj istaživanja bio je utvrditi povezanost između interesa za sadržaje iz nastavnog predmeta TZK i općeg uspjeha na završetku školske godine kao i završne ocjene iz predmeta TZK iz prethodnog razreda. Eksperiment je bio proveden u obliku anonimne ankete, koja je sadržavala pitanja o općem školskom uspjehu, o uspjehu iz tjelesnog odgoja i interesima za sadržaje TZK, na uzorku od 300 učenica iz zagrebačkih gimnazija. Odgovori su podvrgnuti faktorskoj analizi, analizi varijance i diskriminativnoj analizi. Faktorskom analizom utvrđeno je da su aktivnosti iz TZK prema odgovorima identificirane u latentnom prostoru kao pet međusobno nezavisnih faktora. Analizom varijance i diskriminativnom analizom utvrđeno je da odnosi između interesa za sportske sadržaje i općeg uspjeha nisu značajni. Analizom odnosa između interesa za sportske sadržaje i ocjene iz predmeta TZK, dobivena je značajna diskriminativna funkcija, koju su najbolje definirali odgovori: vježbe na spravama, skokovi i vježbe na tlu, a nešto slabije ostale aktivnosti. Razlikama interesa najviše su pridonijeli odgovori učenica sa slabijom ocjenom. The aim of this study was to establish the correlation between the interest in PE-related activities and the scholastic achievements at the end of the school year as well as the final grade in PE in the previous year of school attendance. The experiment was conducted on a sample of 300 secondary school female students from Zagreb as an anonymous survey, which contained questions, related to the general achievements in school, the grade in PE and the interest in PE activities. The answers were subjected to factor analysis, variance analysis and discriminative analysis. Factor analysis showed that PE activities were identified in a latent space as five mutually independent factors. Variance analysis and discriminative analysis found no significant relation between the interest in sports activities and the general school achievements. The analysis of the correlation between the interest in sports activities and the PE grade showed a significant discriminative function which was best identified by the answers: apparatus exercises, jumping and floor exercises, whereas other activities were not so well-defined. The answers of students who had a lower grade contributed to the greatest extent to the differences in interest.

RAZLIKE IZMEĐU REDOVITIH STUDENATA KINEZIOLOŠKOG FAKULTETA I IZVANREDNIH STUDENATA VIŠE TRENERSKE ŠKOLE U NEKIM MORFOLOŠKIM I MOTORIČKIM VARIJABLAMA DIFFERENCES IN SOME MOTOR ABILITIES AND MORPHOLOGICAL CHARACTERISTICS BETWEEN THE REGULAR STUDENTS OF THE FACULTY OF KINESIOLOGY AND OUTDOOR STUDENTS OF THE HIGH SCHOOL FOR COACHES Sporiš, Goran; Faculty of Kinesiology, University of Zagreb, Croatia; goran.sporis@kif.hr Ujević, Branimir; Soccer team "Zagreb" Trošt, Tatjana; Faculty of Kinesiology, University of Zagreb, Croatia Vujnović, Igor; Zagreb Association ofSport motoričke sposobnosti;morfološke karakteristike;bodybuilding motor abilities;morphology;bodybuilding U ovom radu analizirane su razlike između redovitih studenata Kineziološkog fakulteta (koji imaju široki spektar motoričkih znanja) i izvanrednih studenata Više trenerske škole usmjerenja fitness koji su usko specijalizirani (bodybuilding). Istraživanje je provedeno u listopadu 2003. godine na uzorku od 216 ispitanika pripadnika muškog spola, starosne dobi od 21 do 25 godina. Od ukupnog broja ispitanika 149 pripada populaciji redovitih studenata Kineziološkog fakulteta, dok 67 ispitanika pripada populaciji izvanrednih studenata Više trenerske škole usmjerenja fitness . U obradi podataka korištene su metode Studentovog t-testa, analize varijance i diskriminacijske analize. Dokazane su razlike u testovima za procjenu faktora eksplozivne snage i testu za procjenu faktora brzine frekvencije, između grupe izvanrednih studenata Više trenerske škole usmjerenja fitness i grupe redovnih studenata Kineziološkog fakulteta. Razlike u motorici posljedica su morfoloških razlika između grupa ispitanika, ali i razlika u motoričkim znanjima. Redovni studenti Kineziološkog fakulteta imaju širu bazu motoričkih informacija u odnosu na izvanredne studente Više trenerske škole usmjerenja fitness koji su usko specijalizirani (bodybuilding). Posjedovanje većeg broja motoričkih informacija omogućuje studentima Kineziološkog fakulteta brže i efikasnije rješavanje motoričkih zadataka. Test taping nogom naviše je pridonio razlikovanju grupa na globalnoj razini. Veća mišićna masa te manja dužina ekstremiteta (ruku i nogu), uz manji postotak masnog tkiva izvanrednih studenata Više trenerske škole usmjerenja fitness dovela je do statističkih značajnih razlika u odnosu na redovne studente Kineziološkog fakulteta. što je moguće pripisati dugogodišnjem bavljenju bodybuildingom. The aim of the study was to determine the differences between regular students of the Faculty of Kinesiology (which have wide spectrum of motor knowledge) and outdoor students of High School for Coaches (steer fitness, who tightly specialise in bodybuilding). The sample comprised 216 male students, age 21-25, divided into two groups. The first group encompassed the regular students of the Faculty of Kinesiology (N=149), while the second group consisted of 67 students of the High School for Coaches (steer fitness). The methods used in data processing were Student t-test, analysis of variance and discriminative analysis. The differences were observed in explosive strength and frequency of the repetitive movements. The variable that contributed the most to the differentiation of the groups was foot tapping. The regular students of the Faculty of Kinesiology had wider overall motor knowledge, which enabled them to perform better in more complex motor assignments. The outdoor students of the High School for Coaches showed bigger muscle mass and less fat tissue that might be ascribed to the many years spent in specific bodybuilding training process.

PRIJELOMI ZAMORA U AKTIVNIH I REKREATIVNIH SPORTAŠA STRESS FRACTURES IN ACTIVE AND RECREATIONAL ATHLETES Bojanić, Ivan Ivković, Alan Smoljanović, Tomislav Pećina, Marko; marko.pecina@zg.t-com.hr prijelomi zamora;kost;uzroci nastanka;dijagnoza;liječenje;sportaši stress fracture;bone;origin causes;diagnosis;treatment;athletes Prijelomi zamora su djelomični ili potpuni prijelomi kostiju koji nastaju djelovanjem mnogobrojnih ponavljanih sila slabijih od sile koja je potrebna da slomi kost jednim djelovanjem i kao takvi predstavljaju sindrome prenaprezanja kostiju. Čest su problem sportske medicine, obuhvačajući između 1,1 i 10% svih sportskih ozljeda. Brojni su čimbenici koji pogoduju nastanku prijeloma zamora, a najčešći uzrok, u 22 do 75% slučajeva, su pogreške u treningu, tj. „prerano, previše“. Za postavljanje dijagnoze prijeloma zamora, važno imati na umu mogućnost takvoga stanja. Klinička dijagnoza jest osnovni postupak koji se kasnije, prema potrebi, nadopunjuje i drugim dijagnostičkim metodama: radiografijom, scintigrafijom, kompjutoriziranom tomografijom i magnetskom rezonancijom. Za najveći broj prijeloma zamora dovoljno liječenje jest kratkotrajan prekid sportske aktivnosti u trajanju od 4 do 6 tjedana koji dovodi do nestanka boli te zatim slijedi postupan povratak sportu. Prijelomi zamora pojedinih lokalizacija, vrat i trup bedrene kosti, prednji dio srednje trećine tibije, navikularna kost stopala, baza pete metatarzalne kosti, itd., imaju veći broj komplikacija tijekom liječenja te zahtijevaju posebno, dugotrajnije liječenje, a katkad i kirurško. Konačno, kao i u svim sindromima prenaprezanja, prevencija je ključna riječ. Stress fractures, which are classified among overuse injuries of bone, may be defined as partial or complete bone fracture that results from repeated application of stress of less strength than the stress required to fracture bone in a single loading. They are common problem in sports medicine comprising between 1.1 to 10% of all athletic injuries. Causes are many, but training errors, i.e. „too soon, too much“, are the most frequently encountered cause of stress fractures, causing stress fractures in as many as 22 to 75% cases. To diagnose a stress fracture, it is essential to have the possibility of such a condition constantly in mind. Clinical examination represents basic diagnostic procedure followed later on by other diagnostic methods: radiography, scintigraphy, computed tomography and magnetic resonance imaging. For the most of stress fractures sufficient treatment is rest from offending athletic activity during 4 to 6 weeks leading to disappearance of pain and gradual return to sport activities. Stress fractures in some localizations, femoral neck (tension side), anterior cortex of the tibia, tarsal navicular, fifth metatarsal, etc., have higher number of complications during the treatment and require additional treatment, and in some cases even surgical intervention is appropriate. Finally, as in the most of the injuries belonging to the overuse group, prevention is the key word.

VRIJEDNOST INFRACRVENE SPEKTROSKOPIJE U ODREĐIVANJU SASTAVA TIJELA VALUE OF NEAR-INFRARED LIGHT INTERACTANCE IN BODY COMPOSITION ASSESSMENT Sorić, Maroje; Faculty of Kinesiology, University of Zagreb, Croatia; masoric@kif.hr infracrvena spektroskopija;sastav tijela;masno tkivo NIR;body composition;body fat Metoda infracrvene spektroskopije (ICS) došla je u Hrvasku tek prije nekoliko godina. Slijedom toga pojavila se potreba za kvlitetnim vrednovanjem te metode. Cilj ovog rada bio je pregledom recentne literature doći do zaključaka o vrijednosti infracrvene spektroskoopije u određivanju sastava tijela. Poseban osvrt dan je na upotrebu dotične metode kod sportaša. ICS je metoda koja se koristi refleksijom elektromagnetskog zračenja infracrvenog spektra za određivanje gustoće tijela. Metoda je vrlo jednostavna, neinvazivna i komforna. Mjerenja se izvode na bicepsu dominantne ruke u odraslih i subskapularno u djece. Iz pregledane literature može se zaključiti da mjerenje kožnih nabora ostaje najpouzdanija terenska metoda za određivanje sastava tijela, te da infracrvenu spektroskopiju ne treba pretpostaviti ni metodi mjerenja kožnih nabora niti bioelektričkoj impedanciji. ICS se ne preporučuje koristiti u pretilih osoba, kroničnih bolesnika ni u djece. Kod sportaša ju možemo koristiti, ali samo kod sportašica u dobi od 18 do 27 godina, te kod hrvača srednjoškolske dobi. U ostalih sportaša preporučuje se mjeriti kožne nabore, a isto treba činiti i s djecom. U dječjoj populaciji može se koristiti i BIA, koja najvažnije mjesto ima u pretilih osoba te kroničnih bolesnika. Near-infrared light interactance (NIR) was first introduced in Croatia only a couple of years ago. That produced the need to assess its value in body composition assessment. The aim of this article was to review recent publications about NIR and draw conclusions about its application in various parts of the population, especially in athletes. Near-infrared light interactance uses reflection of near-infrared light from lean body mass to measure body density. It is simple, non invasive and comfortable. The measurement is taken at the mid-point of the dominant bicep in adults and subscapulary in children. From reviewed publications it is possible to conclude that skin fold thickness measurement remains the field method of choice in body composition assessment and that even bioelectrical impedance analysis (BIA) should be preferred over NIR. Near-infrared light interactance cannot, yet, be used for overweight and obese individuals, patients with chronic illnesses nor for children. In sports its application is restricted to female collegiate athletes and high school wrestlers. Other athletes should be analyzed with skin fold thickness measurement. The same is recommended for children, where it is possible to use bioelectrical impedance analysis. BIA is the preferred method for overweight and obese individuals and patients with chronic illnesses.

NAJČEŠĆE KOŽNE PROMJENE KOD SPORTAŠA S AKCENTOM NA STOPALO THE MOST FREQUENT SKIN DISEASES OF FEET IN ATHLETES Dellale, Nevia; Poliklinika za dijagnostiku ''Osiguranje Zagreb'', Nemetova, Zagreb Vidović, Gordan; Hrvatska udruga zdravstvenih djelatnika u košarci Vidović, Ivo; Hrvatska udruga zdravstvenih djelatnika u košarci kožne bolesti;gljivične infekcije;sportaši skin diseases;fungal infections;athletes Ne treba naglašavati kako su sportaši posebno izloženi pojedinim kožnim oboljenjima, koje ma koliko se činile bezopasnima, mogu izazvati ozbiljne poremećaje, a tako i onemogućiti postizanje vrhunskih sportskih rezultata. Koža kao najveći organ našeg tijela (1,5-1,8 m²) ujedno predstavlja i prvu barijeru između organizma i negativnih utjecaja okoline. Brojne povrede, trenje, pojačano znojenje, bliski kontakti sa ostalim sportašima, česta putovanja i niz drugih čimbenika mogu biti podloga za remećenje strukture, a time i zaštitne funkciju kože. Svaka promjena na koži mora se shvatiti ozbiljno, a pozornost treba usmjeriti ka prevenciji, pravovremenom liječenju, te sprječavanju recidiva i daljnjeg širenja na ostale članove sportskog tima, ako govorimo o virusnim, bakterijskim ili gljivičnim kožnim bolestima. The importance of skin diseases occurring in people playing various sports is of special interest. Therefore, usually benign skin conditions may become serious and disabling in this particular group of patients and make impossible for them to achieve outstanding results. Skin is the biggest organ of our body (1.5-1.8 m2), and not less important, presents a first barrier in complex interactions between individual organism and surrounding nature. Injuries, friction, excessive sweating, close contact with other players, a lifestyle related to constant traveling and many other factors cause misbalance in skin structure and its protective function. Every skin lesion has to be treated immediately, making the treatment easier, and stopping it from spreading to other players of the team if we treat the infectious skin disease. Still, the most important approach should be prevention.

TJELESNO VJEŽBANJE I NEKI ASPEKTI PSIHOLOŠKOG ZDRAVLJA PHYSICAL ACTIVITYAND SOME ASPECTS OF MENTAL HEALTH Bungić, Mario; Kineziološki fakultet Sveučilišta u Zagrebu Barić, Renata; Kineziološki fakultet Sveučilišta u Zagrebu; renata.baric@kif.hr tjelesna aktivnost; mentalno zdravlje;psihomatsko stanje pojedinca physical activity; mental health;psychosomatic state Razvoj tehnologije, sve izraženiji sedentarni način života, te nedovoljna tjelesna aktivnost predstavljaju prijetnju psihosomatskom stanju pojedinca na početku 21. stoljeća. Kako su brojna istraživanja pokazala da redovita tjelesna aktivnost jača organizam, razvija motoričke sposobnosti, smanjuje rizik od prerane smrti, doprinosi socijalizaciji, poboljšava opće zdravstveno stanje, te pozitivno utječe na mentalno zdravlje, nameće se zaključak kako bi upravo vježbanje trebalo biti dio općeg obrazovanja i kulture življenja. Cilj ovog rada je analizirati spoznaje iz literature, kako domaće tako i strane, koje se bave tjelesnom aktivnosti kao jednim od čimbenika koji pridonose psihološkom zdravlju pojedinca. Drugim riječima, prikazat će se doprinos tjelesnog vježbanja u smanjivanju anksioznosti i stresa, odnosno povećanju zdravstvenog stanja pojedinca, kao i veza između tjelesnog vježbanja i samopoštovanja, te će se pokušati objasniti utjecaj tjelesnog vježbanja na socijalizaciju i psihosomatsko stanje pojedinca. Technology development, more domicile way of life, and insufficient physical activity represent a threat to psychosomatic state of the individual at the beginning of 21st c. As many researches have shown that regular physical activity strengthens the body, develops motor skills, reduces the risk of early death, contributes to the socialization, improves general health and positively affect mental health, we come to conclusion that the exercise should be a part of general education and culture of life. The aim of this work is to analyze the findings from the literature, both domestic and foreign, that are engaged in physical activity as one of the factors that contribute to the psychological health of individuals. In other words, the contribution of physical exercise in reducing anxiety and stress, and increasing the health of individuals, as well as the connection between physical exercise and selfesteem will be elaborated and the impact of physical exercise on socialization and psychosomatic state of the individual will be explained.

Cilj istraživanja bio je utvrditi postoje li kvalitativne neuromuskularne promjene i odstupanja od zdravog obrasca pokreta izražene u površinskom elektromiografskom signalu te u kojoj se mjeri one razlikuju ovisno o korištenoj operativnoj tehnici jednu godine nakon rekonstrukcijeACL-a. Ispitanici su bili raspoređeni u tri homogene skupine. Prvu eksperimentalnu skupinu (n=5) činili su ozlijeđeni sportaši nogometaši koji su bili tretirani tehnikom rekonstrukcije ACL-a patelarnim transplantatom (PAT). Drugu eksperimentalnu skupinu (n=5) činili su ozlijeđeni sportaši nogometaši koji su bili tretirani tehnikom rekonstrukcije ACL-a tetivnim transplantatom mišića gracillisa i semitendinosusa (STG). Treću, kontrolnu skupinu činili su potpuno zdravi nogometaši (MODEL). Prag mišićne aktivacije određen je kao 30% maksimalne amplitude srednje anvelope elektromiografskog signala pojedinog mišića u kontrolnoj skupini. Rezultati godinu dana nakon rekonstrukcije pokazuju statistički značajno kraće vrijeme aktivnosti mišića vastus lateralis u fazi leta grupe PAT(.0249, p=.05 i .005051, p=.05, uz primjenu Bonferroni korekcije) u odnosu na Model, kasniji kraj aktivnosti mišića vastus medialis grupe STG u fazi odraza (.0179, p=.05 i .005051, p=.05, uz primjenu Bonferroni korekcije) u odnosu na Model te kraće vrijeme aktivnosti mišića vastus lateralis u prvoj fazi doskoka grupe PAT (.0132, p=.05 i .015873, p=.05, uz primjenu Bonferroni korekcije) u odnosu na grupu STG. Rezultati pokazuju neuromuskularne promjene kod eksperimentalnih skupina nakon rekonstrukcija i potpune rehabilitacije. Na temelju rezultata ovog istraživanja nismo u mogućnost ustvrditi koja je od prezentiranih tehnika rekonstrukcije ACL-a primjerenija. This study aimed at comparing two most commonly used ACL reconstruction techniques in Croatia. Subjects were chosen amongst patients who were all active soccer players operated on by the same physician and rehabilitated in the same clinic, by the same therapist. They were divided into two groups according to ACL reconstruction technique used: PAT group (n = 5) was treated byACL reconstruction using patellar tendon graft and STG group (n = 5) was treated byACLreconstruction technique using gracillis and semitendinosus tendon graft. Control group (MODEL) comprised of completely healthy active soccer players. One year after the reconstruction our subjects performed one legged vertical jump using their injured leg and surface electromyographic signals of muscles rectus femoris, vastus lateralis, vastus medialis and biceps femoris were recorded.Vertical jump cycle was divided into five phases based on vertical force platform measurements. Muscle activity threshold was defined at 30% of maximum amplitude of mean envelope of individual muscles in MODEL group and several variables describing muscle activity were defined. Nonparametric statistical methods (KruskalWallis test and consecutive Mann Whitney tests with Bonferroni correction) showed some statistically significant differences: shorter activity period of the muscle vastus lateralis in the flight phase for the PAT group (.0249, p=.05 and .005051, p=.05, with Bonferroni correction), delayed end of vastus medialis muscle activity in the take off phase for the STG group (.0179, p=.05 and .005051, p=.05, with Bonferroni correction) when compared to MODEL group and longer activity of the muscle vastus lateralis in the STG group (.0132, p=.05 and .015873, p=.05, with Bonferroni correction) with respect to the PATgroup in the landing1 phase. Based on this we are unable to conclude which of these two surgery techniques should be preferred.

IZVANKURIKULARNE SPORTSKE AKTIVNOSTI DJECE PREDŠKOLSKE DOBI: UTJECAJ NA MOTORIČKA POSTIGNUĆA I TJELESNU PISMENOST EXTRACURRICULAR SPORTS ACTIVITIES IN PRESCHOOL CHILDREN: IMPACT ON MOTOR ACHIVIEMENTS AND PHYSICAL LITERACY Caput-Joginica, Romana; Agronomski fakultet Sveučilišta u Zagrebu, Hrvatska; romana.caput-jogunica@zg.t-com.hr Lončarić, Darko; Učiteljski fakultet, Sveučilište u Rijeci de Privitello, Sergio; Fitness Centar „Studio S“, Rijeka predškolci; motorička postignuća;tjelesna pismenost preschool children; motor achievements;physical literacy Istraživanje je provedeno u svrhu utvrđivanja utjecaja izvankurikularnog sportskog programa na motorička postignuća i tjelesnu pismenost djece u dobi od 4 do 6 godina. U tu svrhu primjenjena je baterija od šest motoričkih testova poznatih metrijskih karakteristika namijenjenih procjeni koordinacije, tjelesne snage, gibljivosti i ravnoteže. Na rezultatima su izračunati parametri osnovne deskriptivne statistike, multivarijatnom analizom varijance izračunate su promjene u motoričkim sposobnostima između dva mjerenja (početno i završno) te interakcijski efekt pojedine varijable u ponovljenom mjerenju na globalne rezultate motoričkih sposobnosti u odnosu na točku mjerenja i u odnosu na spol. Rezultati su potvrdili dosadašnje spoznaje koje se odnose na pozitivan utjecaj redovitog tjelesnog vježbanja na razvoj motoričkih sposobnosti i međupovezno tjelesne pismenosti predškolaca. Osim toga sukladno rezultatima prethodnih istraživanja utvrđene su statistički značajne razlike u motoričkim postignućima između djevojčica i dječaka, dominacija dječaka u rezultatima motoričkih testova namijenjenih procjeni eksplozivne snage i koordinacije, a djevojčica u testovima dinamičke snage, gibljivosti i ravnoteže. The aim of the research was to determine the influence of an extracurricular sports program on motor abilities and physical literacy of preschool children aged from 4 to 6 years. For this purpose, the battery of six motor tests of known metric characteristics was used to measure the following motor abilities: coordination, strength, flexibility and balance. The data were calculated by descriptive statistics. The differences in motor abilities between two time points (initial and final), as well as the interactional effect of a single variable on the global results of motor abilities in repeated measurement with regard to the point of measurement and gender, were calculated by multivariate analysis of variance. The obtained results have confirmed the previous findings describing the benefits of continuous physical activity for the development of preschool children motor abilities and physical literacy. The results are also consistent with the previous research showing that boys have better achievements in explosive strength and coordination, whereas girls have better achievements in dynamic strength, flexibility and balance.

RETROSPEKTIVNO ISTRAŽIVANJE O OZLJEDAMA STUDENATA KINEZIOLOŠKOG FAKULTETA – USPOREDBA DVAJU STUDIJSKIH PROGRAMA RETROSPECTIVE ANALYSIS ABOUT THE INJURIES IN KINESIOLOGY STUDENTS – COMPARISON OF TWO STUDY PROGRAMS Trošt Bobić, Tatjana; Kineziološki fakultet Sveučilišta u Zagrebu; tatjana.trost@kif.hr Ružić, Lana; Kineziološki fakultet Sveučilišta u Zagrebu Ciliga, Dubravka; Kineziološki fakultet Sveučilišta u Zagrebu ozljede; studenti; Kineziološki fakultet;program studija injury; students; Faculty of Kinesiology;study program Glavni cilj ovog istraživanja bio je utvrditi postoji li razlika u učestalosti i specifičnosti ozljeđivanja studenata Kineziološkog fakulteta koji su studirali prema starom (integriranom četverogodišnjem) i onih koji studiraju prema novom petogodišnjem (3+2) programu studija. Istraživanje je provedeno na uzorku od 77 ispitanika (36 studentica i 41 studenta) Kineziološkog fakulteta Sveučilišta u Zagrebu koji studiraju prema novom, petogodišnjem programu studija. Studenti su na kraju osmog semestra ispunili posebni anketni upitnik. Njihovi su rezultati uspoređeni s onima dobivenim na studentima koji su studirali prema starom studijskom programu. Prema rezultatima, učestalost ozljeđivanja studenata Kineziološkog fakulteta koji su studirali prema novom ili starom programu studija vrlo je visoka. U prosjeku svaki se anketirani student ozlijedio barem jedan put u četiri godine studija. Pri tome prevladavaju ozljede zglobova, pogotovo donjih ekstremiteta, a studenti se češće ozljeđuju od studentica. Distribucija ozljeda po godinama studija kod studenata koji su studirali prema starom ili prema novom programu studija vrlo je slična, a rizik ozljeđivanja se u obama generacijama znatno smanjuje tek na četvrtoj godini, što je najvjerojatnije odraz smanjenja broja obveznih praktičnih predmeta. Uvođenje novog programa, dovelo je do znatnog smanjenja rizika ozljeđivanja studenata na sportskoj gimnastici uz istovremeno povećanje rizika ozljeđivanja na rukometu. Osim toga, ozljede koje su pretrpjeli studenti novije generacije lakše su naravi te znatno ne utjeću na tijek njihova studiranja. Nadalje, studenti novije generacije u većem se omjeru ozljeđuju na nastavi, dok su se oni koji su studirali prema starom programu češće ozljeđivali tijekom samostalnog pripremanja ispita. Dva puta dokazana visoka učestalost ozljeđivanja studenata Kineziološkog fakulteta ukazuje na potrebu za uvođenjem određenih promjena u novom programu studija (3+2). U tom smislu vrijedilo bi pokušati sa dodatnim smanjenjem broja studenata po grupi, pogotovo na vježbama, kada se studenti najčešće i ozljeđuju. Osim toga, dodatno povećanje broja predavaonica i sportskih dvorana (terena), u smislu jutarnjeg rasporeda nastave moglo bi spriječiti nakupljanje umora tijekom dugih radnih dana te indirektno smanjiti utjecaj umora na mogućnost ozljede studenata The main goal of this study was to search for possible differences in frequency and specificity of injuries between the Kinesiology students who attended the Faculty of Kinesiology, University of Zagreb according to the old study program (4 years), and those who are attending the new study program (5 years). The sample was composed of 77 students (36 female and 41 male) attending the new study program, who were compared to the previously studied sample. They filled up a questionnaire at the end of their eight semester. Their results where than compared with those of the students who attended the old study program. The results showed a high injury rate in both samples. In average, every examinee suffered at least one injury during his/her study. Mostly, they injured their lower extremities, and the male students where injured more often. The injury risk in both generations decreased only in the 4th study year, probably because of less compulsory practical subjects. The implementation of the new study program resulted in a biggest injury risk during team handball, and smaller risk during sport gymnastics. Besides, the injuries sustained by the students who attended the new study program, were less serious with much lower implications for the regularity of their study. Further, numerous students attending the new study program suffered an injury during the classes, while the ones attending the old study program where mostly injured when preparing the exam. Since the injury rate was very high in both groups, there is a need to introduce some changes in the new study program in order to decrease the injury risk of Kinesiology students. An additional reduction in number of students per group, especially for the practical classes, may be helpful. Besides, a bigger number of classrooms as well as sport halls may implicate a morning schedule, giving the students more time to rest before their afternoon practice, eventually leading to a smaller number of injuries due to fatigue Croatian Olympic Committee 2009-12-30 text pdf http://hrcak.srce.hr/47834 http://hrcak.srce.hr/file/73777 Croatian Sports Medicine Journal (hsmv@kif.hr); Vol.24 No.2; ISSN 0354-0766 (Print) hr The full text of the papers published in this journal is intended for personal, professional and scientific use, as well as educational purposes, with regard to the authors and publishers rights.

POVEZANOST MANIFESTNOG I DOŽIVLJAJNOG PERFEKCIONIZMA SA SITUACIJSKIM PARAMETRIMA UČINKOVITOSTI KOŠARKAŠA CORRELATION BETWEEN MANIFEST AND EXPERIENTIAL PERFECTIONISM WITH THE SITUATIONAL PARAMETERS OF THE BASKETBALL PLAYER EFFICIENCY Sindik, Joško; Dječji vrtić „Trnoružica“, Zagreb, Croatia; josko.sindik@zg.t-com.hr perfekcionizam; doživljajni; manifestni;košarka perfectionism; experiential; manifest;basketball Dva su pravca kojima su autori pristupali problemu istraživanja perfekcionizma: u odnosu na njegove posljedice, i u odnosu na njegove karakteristike. Međutim, u ovom je istraživanju istraživan koncept unidimenzionalnog perfekcionizma, za koji se pretpostavilo da on može biti praktički dvodimenzionalan, te sadržavati manifestnu i doživljajnu komponentu. Perfekcionizam je zbog svojih obilježja pokazao povezanost s mnogim područjima ljudskog ponašanja, te je pretpostavljena njegova povezanost i sa situacijskim parametrima učinkovitosti košarkaša. Osnovni cilj istraživanja bio je utvrditi relaciju manifestnog i doživljajnog perfekcionizma sa standardnim i izvedenim parametrima situacijske uspješnosti u košarci. Sudionici u istraživanju su bili igrači (N = 74) iz devet momčadi koje su nastupale u prvoj fazi prvenstva Hrvatske u košarci, sudionici A-1 lige iz prvenstva 2006/2007. godine. Primijenjena je Burnsova skala perfekcionizma s 10 čestica (verzija prilagođena hrvatskoj populaciji), a iz službenih zapisnika utakmica prvenstva su prikupljeni podaci o parametrima situacijske učinkovitosti košarkaša. Nakon utvrđivanja metrijskih karakteristika upitnika, te kvazi-konfirmatorne faktorske analize, formirani su bruto-rezultati za dvije dimenzije perfekcionizma. Analizirane su kanoničke te pojedinačne korelacije između dvije dimenzije perfekcionizma te stadardnih i izvedenih parametara situacijske učinkovitosti košarkaša . U ovom se istraživanju pokazalo da ima metrijske osnove svesti unidimenzionalni perfekcionizam na dvije dimenzije. Dimenzije manifestnog i doživljajnog perfekcionizma nisu statistički značajno povezane niti s izvedenim, kao ni sa standardnim parametrima učinkovitosti košarkaša. Analiza pojedinačnih korelacija ukazuje na podatak da su «poželjni» situacijski parametri više pozitivno povezani s manifestnim perfekcionizmom. Nije pronađena statistički značajna povezanost između manifestnog i doživljajnog perfekcionizma sa standardnim i izvedenim parametrima situacijske uspješnosti u košarci. Međutim, velik broj značajnih pojedinačnih korelacija ukazuje na važnost budućih istraživanja There are two directions in researching perfectionism: in relation to its consequences and in relation to its characteristics and dimensions. However, this research explored the concept of the unidimensional perfectionism which is supposed to be two-dimensional, containing a manifest and an experiential component. Perfectionism is correlated with many fields of human behavior. For that reason, in this study the correlation with the situational efficiency parameters in basketball was explored. The basic goal of this study was to determine the relation between the manifest and the experiential perfectionism with standard and derived situational efficiency parameters in basketball. Participants in the survey were the basketball players (N = 74) pertaining to nine teams that have performed in the first stage of the Croatian Championship in basketball, members of theA-1 League Championship in season 2006/2007. The Burns Short perfectionism scale with 10 items was applied (adapted version of the Croatian population). Data about basketball performance were collected from the official statistics about the games played in championship. After determining metric characteristics of the questionnaire, and quasi-confirmatory factor analysis, total scores for two dimensions of perfectionism were calculated. Correlations between two dimensions of perfectionism with the standard and derived situational efficiency parameters in basketball, were found. This research has shown the possibility for dividing unidimensional perfectionism in two dimensions. Dimensions of a manifest and a experiential perfectionism component didn't show a significant correlation with the derived, as well as with the standard parameters of efficiency of basketball. Analysis of single correlations points to the fact that "desirable" situation parameters positively are more positive correlated with a manifest perfectionism.No statistically significant correlation between manifest and experiential perfection with standard and derived parameters of situational success in basketball was established. However, a large number of significant individual correlations point to the importance of future research.

RAZLIKE IZMEĐU PLIVAČA KADETA I MLAĐIH JUNIORA U NEKIM ANTROPOMETRIJSKIM KARAKTERISTIKAMA I MOTORIČKIM SPOSOBNOSTIMA DIFFERENCES BETWEEN YOUTH SWIMMERS WITH REGARD TO SOME ANTHROPOMETRIC CHARACTERISTICS AND MOTOR ABILITIES Šiljeg, Klara; Kineziološki fakultet Sveučilišta u Zagrebu Leko, Goran; Kineziološki fakultet Sveučilišta u Zagrebu; gleko@kif.hr Zoretić, Dajana; Kineziološki fakultet Sveučilišta u Zagrebu antropometrijske karakteristike; motoričke sposobnosti; biološki rast i razvoj; plivači anthropometric characteristics; motor abilities; biological growth and development;swimmers Osnovni cilj rada bio je utvrditi razlike, odnose i razlike unutar antropometrijskih i motoričkih sposobnosti hrvatskih plivača kadeta (12, 13 i 14 godina) i mlađih juniora (15,16 godina). Uzorak ispitanika sastojao se od 80 plivača u dobi od 12-16 godina koji su podijeljeni u dvije dobne grupe prema statutu Hrvatskog plivačkog saveza. Ispitanici su u redovitom trenažnom procesu 5 do 8 godine (najmanje 5 puta tjedno). Uzorak varijabli sačinjavao je 27 mjera za procjenu antropometrijskih karakteristika i 11 mjera za procjenu motoričkih sposobnosti. Sve varijable bile su podvrgnute standardnim deskriptivnim postupcima za određivanje njihovih osnovnih statističkih parametara. Za utvrđivanje statistički značajnih razlika između grupa ispitanika korištena je MANOVA, a za utvrđivanje razlika unutar varijabli obje grupe ispitanika korišten je t-test. Na temelju dobivenih rezultata može se zaključiti da postoji statistički značajna razlika između grupe plivača kadeta i mlađih juniora u prostoru logitudinalne dimenzionalnosti skeleta, eksplozivne i repetitivne snage. The main goal of this paper was to determine the relational differences and variations within anthropometric and motor abilities of Croatian cadet (at the age of 12, 13 and 14) and younger junior swimmers (at the age of 15 and 16). The sample of subjects consisted of 80 male swimmers 12 to 16 years of age, undergoing a regular training process lasting 5 to 8 years (at least 5 times a week), divided into two age groups according to the Statute of the Croatian Swimming Federation. The outcome measurments consisted of 27 measures of anthropometric characteristics and 11 measures for the assessment of motor abilities. In order to establish statistically significant differences between the groups, a multivariate analysis of variance - MANOVA was used, whereas the determination of differences within variables pertaining to both groups of examinees was subject to the t-test. Based on the obtained results, we may conclude that a statistically significant difference exists between the group of cadet swimmers and the group of younger junior swimmers in the area of the skeleton longitudinal dimensionality, explosive and repetitive strength.
