An Analysis of the Technique of 720°Turn with Attitude Derriere

本文采用国家体委科研所研究的“近景动态立体摄影测量的方法”,对五名优秀艺术体操运动员屈膝后举腿单足转体720°动作进行了定点拍摄。通过影片解析和自动化数据处理及定量分析,得出了此动作的技术关键、技术特征和一般规律,为改进、普及和提高此类动作提供了理论依据。

Techniques of 720°turn with attitude derriere performed by 5 Chinese top rhythmic gymnasts were filmed with 3-Dcinemotograph at frame rate of 100f/s. The films were then analyzed and digitized with computer. As results the essentialtechnical segments, technical features and some general principles of 720°turn with attitude derriere were reached, providingteaching and coaching of this skill with theoretical basis.
