【摘要】 运用运动学、动力学、肌电图学等,结合摄像解析法,分析中国优秀女子三级跳远运动员跨步跳起跳着地瞬时的动作。研究发现:着地角普遍偏小,与国外优秀女子选手相比差异具有高度显著性;半腱肌的用力程度始终最大;三个方向上有不同程度的力产生,垂直方向的分力最大。更多还原

【Abstract】 The kinematics,dynamics and electromyography are combined with video analysis to analyze the touchdown instantaneous of step jump for Chinese talent female triple jumpers.The research found that there is remarkable difference between Chinese elite female triple jumpers and overseas elite athletes in the touchdown angle,the force level of semitendinosus is the biggest all along,and the component force of vertical direction is the biggest.更多还原
