Study is to evaluate the relation between vertical jump performance and isokinetic knee strength in active volleyball and basketball players. Healthy 42 players volunteered for this study. Wilcoxon Test was used to evaluate the difference between isokinetic peak torque values, for dominant and non-dominant extremities at each angular velocity, of the groups that we identified as male basketball, male volleyball, female basketball and female volleyball. The Mann-Whitney U test was used to compare the quantitative values between the two groups. It was observed that H/Q ratio of dominant extremity was lower than non-dominant extremity (p<0.05). There was no significant difference in terms of sports type in both types of jumping, but the basketball players had statistically significant high values in the measurement formulas. Muscle strength is a significant factor in both sports due to the fact that isokinetic peak torque values of quadriceps and hamstring decrease and H/Q ratio increases gradually from lower angular velocity, is indicator of maximal force to high angular velocity, is indicator of endurance. In addition, when evaluating the athlete's jump performance, not only the jump distance but also the person's height and weight should be taken into account.
