运用运动生物力学研究方法对武术套路南拳旋风脚动作难度及连接难度进行运动学分析,通过分析认为:南拳旋风脚难度动作的动+动+静连接与动+静连接技术存在不同的力学特点,动+动+静连接难度动作第一个动作影响第二个动作的发挥;动+静连接难度动作中的旋风脚540°和旋风脚720°,绝对腾空高度几乎没有提高,主要是提高了空中的旋转速度;起跳缓冲阶段,摆动腿加速摆动对空中技术的影响在旋风脚动作的结构上起着前后衔接的桥梁作用;提高武术运动员的跳跃起跳能力,对完成高质量的南拳旋风脚连接难度动作是十分必要的。
The kinematic analysis of the difficulty and connection difficulty of the south boxer whirlwind foot in the martial arts routine is made by the method of sports biomechanics. According to the analysis, there are different mechanics of dynamic + dynamic + static connection and dynamic + static connection technique of the south boxer cyclone foot. Features, dynamic + dynamic + static connection difficult action The first action affects the second action to play; dynamic + static connection difficult action cyclone foot 540 ° and cyclone foot 720 °, almost no increase in the absolute height of the vacant, mainly to improve The speed of rotation in the air; Take-off and buffering stage, the impact of swing leg acceleration swing on the air technology in the structure of the cyclone foot play a bridging role before and after; to improve the martial arts athletes jumping ability to complete high-quality South Boxer Cyclone Foot connection difficulty movement is very necessary.
