Sažetak

Tijekom tjelesne aktivnosti različiti fiziološki sustavi djeluju sinergijski kako bi omogućili prilagodbu organizma. Uvođenjem inovativnog pristupa kao što je palmarno hlađenje, tj. primjena hladnih obloga na dlanovima, istražuje se potencijal za regulaciju tjelesne temperature tijekom tjelovježbe. U ovom se istraživanju analizira utjecaj palmarnog hlađenja na promjene pulsa, percipiranog napora, tjelesne temperature i opterećenja tijekom aerobne aktivnosti. Cilj je razumjeti može li palmarno hlađenje smanjiti porast tjelesne temperature i subjektivni osjećaj napora te tako potaknuti redovitu tjelovježbu kod osoba koje se suočavaju s poteškoćama zbog napora pri tjelesnoj aktivnosti, odnosno predstavlja li ono inovativan pristup koji može doprinijeti optimizaciji tjelesne aktivnosti i promicanju zdravog načina života. U istraživanju su sudjelovala 24 ispitanika dobi od 20 do 23 godine, prosječne tjelesne spreme i kod kojih u trenutku ispitivanja nisu bila prisutna akutna i kronična stanja, odnosno stanja zbog kojih im je propisana zabrana sportskih aktivnosti od strane liječnika. Isključeni su oni osjetljivi na hladnoću te s akutnim i kroničnim zdravstvenim stanjima ili ozljedama lokomotornog sustava. Korišten je submaksimalni cikloergometarski test Astrand-Rhyming Cycle Ergometer Test kako bi se analizirale razlike u navedena četiri parametra između dvaju uvjeta, sa i bez palmarnog hlađenja. U statističkoj analizi korišteni su deskriptivni postupci, t-test, Wilcoxon test i hi-kvadrat test.Iako su pronađene razlike u pulsu, percipiranom naporu i opterećenju između uvjeta sa i bez palmarnog hlađenja, one nisu bile statistički značajne. Međutim, značajne razlike u tjelesnoj temperaturi, koja se u uvjetu palmarnog hlađenja pokazala nižom nego u uvjetu bez palmarnog hlađenja, potvrđuju potencijalno djelotvornu primjenu palmarnog hlađenja tijekom aerobne tjelesne aktivnosti.
