This study aimed to compare the effects of the activity of the biceps brachii on different contralateral elbow exercises during isometric contraction of the elbow flexor. Twenty-four healthy subjects were recruited to participate in this study. The subjects performed three types of exercise with the contralateral elbow during isometric contraction of the elbow joint on the dominant side: (1) single exercise (no contralateral exercise), (2) concurrent exercise (isometric contraction of the contralateral elbow flexor), and (3) reciprocal exercise (isometric contraction of the contralateral elbow extensor). Electromyography (EMG) data were collected from the biceps brachii. The EMG activity of the biceps brachii was significantly higher for the reciprocal exercise when compared with single and concurrent exercises, respectively (p<0.05). These findings suggest that the reciprocal exercise of the contralateral limb may be beneficial to improve the muscle activity of the elbow joint. It provides useful information to improve the efficacy of exercise performance.
