张坤和TOM的横踢技术运动生物力学比较分析
横踢技术,支撑腿,进攻腿,角速度,肌电
2017/5/26
设置靶模具和信号灯,运用两台CASIO-EXFH25摄像机对两名国际级散打和泰拳选手后横踢动作进行同步拍摄,采用APAS系统(美国)进行三维视频图像解析,用Megwin Me6000表面肌电同步肌肉活动信号,对中泰横踢技术各运动环节支撑腿和进攻腿髋、膝、踝关节速度和角度变化特征,肌肉动员顺序、肌电特征进行对比分析,寻找差距,揭示技术动作内在规律,以期为鞭腿技术动作的教学、训练提供科学依据。

对国内外关于裸足跑生物力学特征研究进行了综述,概括了裸足跑与穿鞋跑在运动学、动力学、生理学等方面的生物力学特征差异。与穿鞋跑相比,裸足跑更多地采用前足着地、更短的步长、更快步频的行进方式,这种模式能大大降低地面的碰撞冲击峰、加载率;裸足跑能更多地利用好足部的本体感觉,从而可能增强足的力量及行进中的稳定性;裸足跑并不比穿鞋跑拥有更低的损伤率,当前没有权威性的证据显示行进中较高运动损伤率是由于巨大、反...
