Objective: The aim of this study was to investigate the relationship between isokinetic relative torques of hip, knee and ankle joints and the height of guide leg jump in young men.

Methods: 27 college male athletes with mean age of 25±3.5 years, height 178.5±7.8 cm and weight of 75.7±10.7 kg voluntarily participated in this study. Isokinetic torque of hip, knee and ankle joints and the height of vertical jump were measured using BIODEX SYSTEM PRO 4 and digital vertical jumping tester systems respectively. Pearson correlation test at p<0.05 was used for statistical analysis.

Results: Results showed that there were significant correlations between height of jump and hip joint flexion (p= 0.047 & r= 0.39) and extension (p= 0.003 & r= 0.55) torques of guide leg, hip joint extension torque of support leg (p= 0.020 & r=0.45) and knee joint flexion (p= 0.019 & r=0.45) and extension torques of support leg (p=0.006 & r=0.52).

Conclusion: The results of this study show that flexion and extension torques of hip joint in guide leg and knee joint in support leg and also extension torque of hip joint in support leg have main effect on height of guide leg jump. Thus, in designing a specific training program for athletes in whom the nature of jump in their sports is guide leg jump, particular attention should be given to hip and knee joints strength.
