Sažetak
This study had as its aim to establish the relations between anthropometric characteristics and tests of explosive force and was performed on a sample of 115 subjects, 15 to 17 years of age who were members of young basketball teams in the SR Croatia. The sample was representative of the young basketball population from all parts of the Republic.
Explosive force was assessed on the basis of the results obtained on five tests:
- high jump (MFESVS)
- standing broad (MFEDSM)
- 20 m sprint with high start (MFE20V)
- throwing of medicine ball, lying on back (MFEBML)
- throwing of basketball, from a sitting point (MFEKOL)
while the morphological characteristics were tested by means of 12 measure. The measures of anthropometric characteristics were formed in such a way that each latent morphological dimension was represented by three variables. In order to assess the longitudinal dimensionality - LDS - of the skeleton these measures were taken:
- the height of the body - VISTIJ
- the leg length - DUŽNOG
- the arm length - DUŽRUK
The transversal dimensionality of the skeleton - TDS - was assessed by:
- the width of the fist - ŠIRŠAK
- the kee diameter - DIJKOL
- the elbow diameter - DIJLAK
while the volume and mass of the body VMT - were assessed by:
- the body weight - TEŽTJ
- the circumference of the upper arm - NABDNAD
- the skin fold of the back - NABLEDJ
- the skin fold of the upper leg - NABPOT.
Relation between morphological measures and the assessed features of explosive force was established by means of the canonic correlation analysis.
Values obtained through canonic analysis indicate a high mutual connection between variables of both groups. Two significant pairs of canonic factors were obtained.
The first pair of canonic factors indicates a significant positive correlation between moprhological characteristics and tests of explosive force, and in interpreted as the measures of a general correlation of these two spaces.
From the structure of factors it is evident that measures of volume and mass have greatest effect on motor activities of explosive nature, whereas the other measures of anthropometric status are somewhat less, but stuill significantly present. Keeping in mind low values of projections of subcutaneous fat measures, it is to believe that volume and mass of the body increase primarly at the expanse of muscular mass. This is corroborated by the fact that success in basketball is largely determined by musculatures of young basketball players.
The structure of the first pair of canonic factors indicates that the process of training basketball players should pay some attention to development of musculatures since it makes a possible performance of those types of activities which are of primary importance for success in basketball.
The second pair of canonic factors significantly negatively correlates the measures of subcutaneous fat tissues extracted on the negative pole, with the results of those tasks of explosive force during which the instantly created maximum muscular force results in relocation of the body in space. The subcutaneous fat tissue can be considered a balast mass in performing tasks structurally and in type of activity very similar to movements prsent in play. For this reason it is necessary to control this morphological dimen sions and not to allow it negative effect upon the motor structure of young players, in the continuing process of creating good basketball players.
