摘要
通过查阅文献、现场拍摄等研究方法,对我国部分优秀男子三级跳远运动员跨步跳中速度的变化、支撑腿的缓冲、摆动腿的摆动、落地角、起跳角、重心腾起角等相关的数据指标进行分析研究.研究结果表明,我国运动员跨步跳踏跳过程水平速度损失过大,向上起跳的垂直速度小;踏跳支撑腿膝关节缓冲大,摆动腿后摆不积极,前摆不充分;着地角较小,产生的制动力大,这些都对后两跳的成绩造成不利的影响.
By using location filming and other methods, the author has analyzed the speed changes, the buffer legs support, legs swinging, landing angle, taking - off angle and center of gravity flight angle, and other relevant data indicators of China＇s elite men＇s triple jump athletes for research. The results show that our athletes steps＇ take- off at the level of loss is too large; the vertical take - off speed is small; the knee buffer is large; legs post- swinging pendulum is not positive, not placed to the full; the angle is smaller, which produces a great stopping force. All these have caused a negative impact on the two jumps that happen after the first one.
