Anthropometry and high-speed elbow flexor performance

Abstract

To examine the anthropometry-performance relationship from high-speed elbow flexor resistive exercise, subjects (n = 73) made three laboratory visits spaced approximately one week apart. Per subject six anthropometric variables were collected: height, mass, body mass index, as well as total, upper and lower arm lengths. Workouts entailed two 60-second sets of elbow flexor (curling) repetitions; mean acceleration and mean torque were measures and averaged from each set. With each of those measurements as criterion variables, multivariate regression utilized the six anthropometric indices to act as predictors of the performance-related variance. Per multivariate analysis, current results failed to demonstrate a significant (P > 0.05) anthropometric-performance relationship. While prior work noted strong relationships, the lack of current study statistical significance may be a function of multiple factors that could include heterogeneity of our sample and the inherent variability seen with high-speed resistive exercise.
