Effect Of Verbal And Visual Feedback On Peak Torque During A Knee Joint Isokinetic Test

The purpose of this study was to assess the effect of verbal and visual feedback on peak torque in male subjects. Thirty male subjects were tested on four separate occasions by executing a knee flexion/extension isokinetic set of four maximal repetitions, at velocities of 60, 120, 180, 240 and 300 deg/sec with a 60 second rest between each velocity set. The velocity order was randomized and visual and verbal feedback to subjects was randomly assigned. A 2 X 5 repeated measures ANOVA was used to analyze the data with α \u3c 0.05. There were no significant differences in peak torque regardless of the presence or absence of feedback. The conclusion of this study was that feedback does not increase peak torque during concentric isokinetic testing. ABSTRACT FROM AUTHO
