摘要：The purpose of the study is to compare the ratio of lower extremity isokinetic hamstring/quadriceps ratio (H/Q), bilateral strength difference (BLD) and relative peak torques (RPT) in volleyball players according to the leagues. 101 volleyball players participated in the study (female=34, male=25 from 1st league; female=21, male=21 from 2nd league). Isokinetic extension and flexion of knee muscle strengths of the volleyball players were determined with isokinetic dynamometer. Independent t test was used to compare volleyball players' flexor and extensor RPT, H/Q ratios and BLD according to their leagues. In the study conducted, it was determined that both male and female volleyball players playing the 1st league had higher RPTs at 60°s-1 and 180°s-1 angular velocities. It was determined that volleyball players’ BLD was within the desired limits, whereas their H/Q ratios were low. As a result, it was determined that the lower extremity isokinetic knee muscle RPT of the volleyball players playing in the 1st League had better values than those playing in the 2nd league, but these values were higher in the extension RPT. Since the essential requirement of volleyball is the jumping strength of the movements, this case may be related to the greater development of the extensor muscles.
