男子跳马“踺子转体180°前手翻”类动作纵转180°技术分析

Analysis on Techniques of Longitudinal Twist 180°in Front Handspring Movements Performed in Men Horse Vaulting

采用三维高速摄影和影片解析的方法,对我国优秀男子体操运动员黄力平、黄华东等人完成跳马“踺子转体180°前手翻”类动作纵转180°技术时的空间及时空特征等,进行比较分析。结果显示,完成纵转180°技术时,应避免在踏板阶段过早转体;应充分利用手臂的非对称性运动,做到“快转体,早摆腿”;推手阶段要尽可能利用腕、肘、肩的弯屈度,充分推伸、拉展等。

In the present paper, the authors use the methods of three-dimensional high-speed photography and film study to make comparative analysis on the characters of space and space - time, in which the longitudinal twist 180?of front handspring movements. The results show that while performing longitudinal twist 180?early twist should be avoided in the period on the footboard; the nonsymmetry of the arms should be made full use of so as to make a 'fast twist and early legswing';the ben wrist,elbow and shoulder should be adopted in the period of pushing hands to make full push,stretch and so on.
