女子单跳后空翻两周同时转体360°动作技术的运动学分析

Kinetic Analysis on Movement Techniques of Backward 2 Somersault with Ⅰ Twist for Women Gymuasts

通过定点高速摄影,拍摄了在全国技巧此赛中完成“后空翻两周同时转体360°”动作的3名优秀女单运动员的影片,经GP2000影片分析仪解析,得到该动作的各项运动学参数。在此基础上,探析了该动作的运动学规律和完成该动作的关键技术要领。

The films of the movement (backward 2 somersault with Ⅰ twist) were obtained by using high-speed photograph in place, which were completed by three elite women acrobats in the national acrobatic competitions. Furthermore, the kinetic parameters of the movement were obtained after analyzing with GP200 film instrument. On this basis, the authors discuss the kinetic law of the movement and the key points of completing the movement.
