Isokinetic evaluation of the healthy knee: Position of the joint at the peak torque

Abstract

Sixty healthy young volunteers were tested bilaterally in order to determine the angle of peak torque (APT) during flexion and extension of the knee at velocities of 60°/s and 120°/s. No differences in laterality were observed in the APT, except for flexion in females, where this angle was greater on the right side at both velocities. In males, the extensor muscle group reached the peak torque sooner than the flexor group at both velocities. In addition, in extension and for both velocities, men reached the APT earlier than women. Thus muscle and gender have an effect on the APT.
