The purpose of this study was to investigate about the differences of the electromyographic (EMG) activities in trained and untrained male subjects during the kip movements on the horizontal bar. The EMGs were picked up with bipolar surface electrodes from dominant superficial muscles in m. pectralis major, m. teres major, m. latissimus dorsi and m. biceps brachii. The movements were recorded by a check polaphy. 1. The discharge of the muscles on the anterior aspect of forearm in trained subjects began to appear before than the discharge of m. pectralis major and m. teres major during the forward swing. On the other hand, the discharge of m. pectralis major and m. teres major in untrained subjects began to appear in earlier stage than those in trained subjects. Furthermore, the discharge of both m. biceps brachii and m. latissimus dorsi which did not appear in trained subjects was see in untrained subjects. 2. The remarkable discharge of m. pectralis major, m.teres major, m. teres major, m. latissimus dorsi and m. biceps brachii in trained subjects was seen during the stage of decreasing angle of shoulder joint which is one of the most important motion for the kip movements. On the other hand, the discharge of m. pectralis major, m. ters major and m. latissimus dorsi in untrained subjects was not so remarkable as the discharge of m. biceps brachii.
