| Summary: | The purpose of this study was to examine the effects of visual feedback and verbal encouragement on peak torque and total work measurements during maximum isokinetic concentric activation of knee extensors. Twenty-seven healthy male subjects between the age of 19 and 42 completed the two test sessions 14 days apart using an isokinetic dynamometer at 60°/s and 450°/s. Visual feedback was provided as real-time display of the moment output. Verbal encouragement was done using a standardised procedure. With visual feedback and verbal encouragement peak torque and total work at both speeds were significantly greater than without. These findings suggest that combined visual and verbal encouragement are strong motivating factors. It is therefore recommended to use feedback and verbal encouragement as part of a standardised procedure during isokinetic testing. |
