Abstract: Abstract: The purpose of this study was to determine the relationship between average force, average torque, peak force, and peak torque produced by the knee musculature. Twenty women were assessed for isokinetic concentric and eccentric knee extensor and flexor muscular strength at a velocity of 90 deg/sec. Correlational analyses showed relationships ranging from r = 0.89 to r = 0.94 for concentric extension, r = 0.92 to r = 0.99 for eccentric extension, r = 0.81 to r = 0.95 for concentric flexion, and r 0.90 to r = 0.96 for eccentric flexion. The strong relationship between the tested variables suggests that any of these variables are appropriate when reporting isokinetic strength data. However, because average values are dependent on the preload and range of motion through which a joint is assessed, it is imperative that these variables remain consistent between and among subjects. If this is not possible, the use of peak measures is recommended.
