A STUDY OF THE PROCESS OF IMPROVEMENT IN ARCHERY / 体力科学

The form and electromyographic pattern of archery shooting were compared between experts and amatures. Using methods are electromyography, photography and X-ray photography.<BR>In the expert group, the shoulder joint of the pushing arm is in neutral position of rotation and the forearm is in supinated position. In the amature group the shoulder joint is in externally rotated and forearm is pronated. The delta muscle provides more powerful abduction of the shoulder in neutral position of rotation.<BR>The different discharge pattern of shoulder girdle muscles between two groups suggests that fixation of the bow is essentially important from release to follow-through.
