Abstract

The purpose of this study was to determine if a relationship exists between voice command intensity and maximum torque production of an isometric muscle contraction. Thirty nine healthy subjects ranging in age from 18-30 participated in this study. The maximum torque production of triceps brachii was measured using a Cybex II+ isokinetic dynamometer in response to varied, tape recorded voice commands. Data was analyzed by a series of analysis of covariance (ANCOVA) and analysis of variance (ANOVA) for an unbalanced incomplete-block crossover trial design. No significance was found between voice intensity and peak torque. Gender was found to impact torque production, and accounted for all differences noted (P {dollar}<{dollar}.05). Further research in this area is warranted due to small sample size and the results of this study conflicting with those of an earlier study.
