THE PROFILE OF ISOKINETIC STRENGTH, IDENTIFICATION OF IPSILATERAL AND BILATERAL RATIO OF PEAK MUSCLE TORQUE IN KNEE FLEXORS AND EXTENSORS IN SOCCER PLAYERS
Abstract
The aim of the study was to determine the profile of isokinetic strength of elite young soccer players and to determine the ratio of muscle strength between knee flexors and extensors and their bilateral strength imbalances. Diagnostics was performed on the isokinetic dynamometer at five angular velocities.
Peak torque extensors and flexors were significantly reduced with increasing angular velocity in both preferred and non-preferred limbs. Increasing angular velocity had a significant effect size of ipsilateral H:Q ratio in both limbs.
An insignificant difference was found between the results of the preferred and non-preferred limbs. Precise determination and quantification of muscle strength imbalances is essential for determination of the fundamental level of organized and intentionally controlled training process and for early compensation of the found imbalances as prevention against potential injury.
