| Research Abstract |
In gymnastic motion, shoulders should play important roles including with both strength and flexibility. The purpose of this study was to investigate the better motion of shoulder joints in giant swing before the dismount from a horizontal bar and swing motions on parallel bars. At the release instant of the dismount from a horizontal bar, the greater angular momentum was observed for the higher level gymnasts. Gymnasts have to extend shoulder joint more quickly and vigorously so as to get the grater angular momentum at the release instant. As for swing movements on parallel bars there was a strong correlation between inclination angle of the scapular and extension angle of the shoulder joint. There was a tendency of the wider range of motion of shoulder joint for the higher athlete level.
