| 摘 要： | 对谢荔梅在2007年田径大奖赛总决赛上创造14.90 m女子三级跳远亚洲纪录的三跳技术进行运动学研究。结果表明,谢荔梅的三级跳远技术属于平跳型,采用的是单臂摆技术;左右腿力量均衡;水平速度损失率较低。单足跳离地时刻支撑腿蹬伸不充分;单足跳的起跳角大;跨步跳起跳的垂直速度过低。助跑绝对速度差,今后提高助跑的绝对速度是她创造优异运动成绩的决定性因素。

| Abstract: | This paper studies Xie Limei's triple jump technique when she set an Asian record of 14.90m on 2007 National Athletic Grand Prize Series Finals with kinematics analysis method.The result shows Xie Limei's triple jump technique belongs to flat jump,adopting single arm wave;strengths of her two legs are balanced;the loss rate of horizontal velocity is relatively low.Her supporting leg to pedal and stretch is insufficiently;her hop jumping take a large angle;the vertical speed of stepped up is too low.Her absolute speed of run-up is not satisfied.In future,improving the absolute speed of run-up is the decisive factor for her excellent performance. |
