Abstract: The purpose of this study was to examine the validity of the average and peak torque values of the knee extensor and flexor musculature obtained through the data extraction technique. Twenty women (age = 20.2 ± 1.01 yr; height = 169.0 ± 6.8 cm; weight = 60.8 ± 5.5 kg) were assessed for isokinetic peak and average torque of the knee musculature at a velocity of 90 deg/sec. Subjects were randomly assessed through a range of motion of 5-90 deg and 25-70 deg. Peak and average torque values within a range of motion of 25-70 deg were extracted from the tested range of motion of 5-90 deg. Correlational analyses between the tested and extracted variables revealed relationships ranging from r = 0.79 to 0.95. Paired t tests found no significant differences (p < 0.006). These findings suggest that the data extraction techniques are valid.
