武术旋子转体720°--跌叉动作技术诊断

对我国 2 0 0 0年全国武术锦标赛自选拳比赛前 3名运动员完成旋子转体 72 0°——跌叉的动作进行了高速摄影 ,通过生物力学实验 ,取得了相关指标与数据 ,结合多媒体技术 ,制作出了该动作各关键时相的三维立体动感图。分析发现 ,3名运动员在该动作上在比赛中虽未扣分 ,但从技术角度上分析 ,旋子的腾空高度太低、空间滞留概念不清、本体感觉差、动作不到位

The Technical Diagnose on Movement Revolving Turn 720°-Alling Cross by Adopting Multi-media Techniques in Martial Arts

In the optional Exercise completion of National Martial Arts Championship in the Years of 2000, by combining high speed photograph and biomechanical experiment, the relevant index and data are obtained. Based on the index and data, the three dimensional dynamic picture is drawn by adopting multi media techniques. The result shows that though three players get full marks in the movement, their performances are imperfect. In terms of skill, the height of rising into the sky is too low, the holding up in space are obscure, the proprioceptor is barely satisfactory, The detail of movement are not presented adequately.
