摘要：Objective.The purpose of this study was to examine the maximal voluntary peak torques of the quadriceps and hamstring muscles,and the torque ratio between these muscle groups in second division basketball players.Material and Methods.Isokinetic peak torques were measured using the Isomed 2000 dynamometer at 60 and 180°s1.Twenth-three second division basketball players (age: 22,7±4,14 years,height: 195,9±6,59cm,weight: 94,3±13,4kg,BFP: %11,98±3,6) involved in this study.Results.Table 1 shows the maximal voluntary peak torques of the quadriceps (Q) and hamstring (H) muscles and the torque ratio between these muscle groups Table 1 Peak isokinetic knee torques and H/Q Values at 60 and 180°s-1(Concentric /Concentric) (Con/Con) The average right and left H:Q ratios at 60°s-1 were above the normal isokinetic range of 60%–69%.However,at 180°s-1,the mean right and left H: Q ratios were within the normal range.Conclusion,The normal Hcon/Qcon ratio is 0.60.This ratio has been used to assess thigh muscle imbalance,but the functional Hcon/Qcon ratio is related with velocity of the test it increased above 1.00 with increasing velocity and more extended knee joint positions,it means the more velocity the more ratio (Burkett,1970;Coombs and Garbutt,2002).Coaches and physical therapists may use results of the present study in order to evaluate and plan exercise programs of ankle musculature during training and rehabilitation.
