Sažetak  

Cilj ovog istraživanja je bio da se utvrdi da li ispoljavanje maksimalne izometrijske mišićne sile pri određenom uglu u zglobu (80°, 110° i 140°) može služiti kao prediktor 1 RM-a kod kretnog zadatka nožni potisak(leg press).Istraživanje je sprovedeno na grupi od dvadeset i četiri studenta (N=24), muškog pola u okviru 2 odvojene sesije sa po 7 dana odmora između svake. Antropometrijska mjerenja i procjena mišićne sile, odnosno 1 RM-a izvršeno je metodom repetitivnih maksimuma do otkaza na trenažeru za nožni potisak (leg press, V-Gym Hrvatska) u okviru prve sesije. Maksimalna izometrijska sila (Fmax) muskulature nogu mjerena je testom uzastopnih maksimalnih kontrakcija u laboratorijskim uslovima na trenažeru nožni potisak uz pomoćsonde dinamometra i softwerskog sistema Globus Ergo Tesys System 1000. Analizom rezultata dobijenih na osnovu linearne regresije, autori zaključuju da sa preciznošću od  84,5% možemo izvršiti procjenu 1RM-a u vježbi nožni potisak na osnovu maksimalne izometrijske sila ispoljene pri uglu u zglobu koljena od 140°. Rezutati dobijeni ovim isztraživanjem mogu poslužiti aplikativno u praksi prilikom procjene 1 RM-a na osnovu mjerenja maksimalne izometrijske sile za dati kretni zadatak.

Ključne riječi: Mišićna sila, predikcija, 1 RM, nožni potisak
