Abstract

The purpose of this study was to compare the effects of speed and concurrent visual feedback on mean peak torque values at dynamometer speed of 45 and 120 degrees per second to determine if a significant increase or decrease in the force-velocity relationship exists. The dominant limb of thirty male subjects between the ages of 18 and 35 were tested eccentrically on the KIN-COM dynamometer. All data were analyzed by three one-way repeated measures ANOVAs. The results revealed no significant differences in mean peak eccentric torque during three continuous concentric-eccentric contractions between 45 and 120 degrees per second (p>.05). A one-way repeated measures ANOVA revealed no significant differences in mean peak torque at 120 degrees per second with and without concurrent visual feedback (p>.05), but revealed a significant increase in mean peak torque at 45 degrees per second with concurrent visual feedback (p=.05).
