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 high speed photography was performed on the athletes completing the rotation of 72 0 ° - Chameleon of the top three athletes in the national martial arts championship in 2000 with biomechanical experiments. The relevant indicators and data were obtained through the combination of multimedia technology , Produced a three-dimensional dynamic map of the key phase of the action. Analysis found that the three athletes in the action in the game, although not deducted points, but from a technical point of view, the swinging height is too low, the concept of space retention is unclear, the body feel bad, the action is not in place
