[Purpose] This study investigated the relationship between leg extensor torque and hip flexor and extensor muscle strengths of males and females. [Subjects] The subjects were 53 healthy adults with no disorders of the lower limbs. [Methods] For both males and females, we measured the peak torque relative to body weight of the right and left legs during extension, as well as hip flexor and extensor muscle strengths relative to body weight. We then examined the relationship between leg extension torque and hip flexor and extensor strengths using Spearman correlation coefficients. [Results] We found strong to moderate correlations between male left and right extension torque and hip flexor and extensor strengths, and moderate to weak correlations between female left and right extension torque and hip flexor and extensor strengths. [Conclusion] In males, hip flexor and extensor muscles play a large role in producing leg extension torque, whereas their contribution is less in females.
