† indicates a significant interaction between main effects of arms × time (days);* denotes significant (p<0.05) differences between day 1 pre-EE and other days.Note: SOR refers to each subject’s perception of muscle soreness while arm was actively extended. ROM refers to active elbow range of motion. CIR refers to arm circumference at 8-cm above elbow. CIR at all anthropometrical landmarks (e.g. 4, 6, and 10-cm above elbow) followed a similar pattern, therefore, data was only presented from CIR at 8-cm. MDF refers to EMG median frequency. Derivation of regression intercept (β0) and slope (β1) are described in the text.
