Summary/Abstract: The aim of the study was to present isokinetic strength profile of knee flexors and extensors during concentric contraction in young soccer players. Particularly in knee flexors was evaluated also strength during eccentric contraction. Research group was state from young soccer players U17 category (n=19, age=16,4±0,3 years). All of them are the participant of highest junior soccer league. Isokinetic strength was evaluated by isokinetic dynamometr Cybex Humac Norm in following angular velocities: 30, 60 and 120°/s in eccentric contraction and 60, 180, 240 and 300 °/s in concentric contraction. The results did not revealed significant differences at three different speed levels of knee flexors’ strength during eccentric contraction (p>0,05).
