Abstract
[Purpose] The purpose of this study was to investigate the relationship between knee extensor strength and leg extension torque in males and females. [Subjects] The subjects were 48 healthy adults with no problems in the lower leg. [Method] Using a StrengthErgo, we measured the peak torque relative to body weight of right and left leg extension. We also measured left and right knee extension strength relative to body weight, using a hand-held dynamometer. We then examined the relationships between knee extension strength and leg extension torque. [Results] We found a significant difference in males’ and females’ leg torque, but not in their knee extension strengths. We also found a mild correlation between males’ knee extension strength and leg extension torque, but not for females. [Conclusion] We found a difference between males and females in the contribution of knee extension strength to the exertion of knee torque.
