Eccentric torque/velocity and power/velocity relationship of the elbow flexors

The purpose of this study was to investigate the eccentric torque and power/velocity relationships of the elbow flexors. Forty (20 males and 20 females) recreationally trained individuals randomly performed four maximal eccentric actions at five different velocities on a Biodex Isokinetic Dynamometer. A 2 x 6 (sex x velocity) mixed factor repeated measures ANOVA analyzed peak eccentric elbow flexor torque. There was no interaction, but there were significant main effects for velocity and sex. Pairwise comparisons demonstrated that torque values collected at 180°/sec were significantly less than velocities of 240°/sec and 300°/sec A 2 x 5 (sex x velocity) mixed factor repeated measures ANOVA analyzed peak eccentric elbow flexor power. There was a significant main effect for velocity in both males and females. Pairwise comparisons demonstrated that for both sexes, as velocity increased, peak eccentric power increased significantly at each velocity. These results demonstrate that an increase in velocity had little or no effect on eccentric elbow flexor torque, and eccentric elbow flexor power significantly increased with increases in velocity.
