雙槓屈體後空翻兩周結束動作之運動學分析

The Kinematics Study of Double Salto Somersault

摘要


目的:本研究是透過運動學分析,比較成功與失敗雙槓屈體後空翻兩周結束動作表現的差異,進一步找出實施成功動作的重要關鍵所在,以提供作為臺灣男子競技體操教練與選手們從事專項實務訓練時之參考。方法:本研究採用一部高速攝影機(SANYO; 60 Hz)來記錄5位男子競技體操選手的動作表現(共30筆資料),運用Kwon 3D動作分析軟體進行資料處理,實驗所得資料以相依樣本t-test進行考驗。結果:本研究結果如下:一、成功動作在支撐位置有較高的身體重心垂直高度;二、成功動作在離手位置有較小的髖關節角度;三、成功動作在空翻二周位置有較高的身體重心垂直高度;四、成功動作在著地位置有較大的髖關節角度。結論:本研究結論經由統計分析之結果歸納成功動作有下列技術表現:一、在支撐位置應避免過早實施下肢朝前上方擺腿動作,方能減少身體重心往前方水平位移,如此可有助於離槓時身體重心得以往上移動;二、空翻兩周過程中必須盡可能的抱緊雙腿,藉以縮小髖關節角度進而增加空翻旋轉速度;三、著地位置時需伸展髖關節角度,有利於著地階段體勢之控制。

Purpose: The purpose of this study was to compare the successes and failures of the double salto somersault from parallel bars in motor performance through kinematic analysis and to identify the important keys to a successful movement. This study could provide Taiwanese male gymnastics coaches and players a guide for specific practical training. Methods: It is used a high-speed camera (SANYO; 60 Hz) to record the performances of five male gymnasts (30 trials) and used Kwon 3D motion analysis software for data processing. The experimental data was tested by a sample t-test. Results: 1. The center of body gravity movement in the support position was found to be higher in successful movements. 2. The hip joint angle in the hand take off position was found smaller in successful movements. 3. The center of body gravity at the second somersault was found higher in successful movements. 4. The hip joint angle landing position was found larger in successful movements. Conclusion: Successful movements of technical performance was based on the results in the following: 1. In the vertical support position, an avoidance of flexion early on would help the center of gravity move up after away from the bar. 2. During the second somersault, the gymnasts could increase the rotational speed by holding the legs early in the movement to reduce the hip flexion angle. 3. During landing, hip extension could influence body control to produce a stable landing.
