Study on Key Kinematic Parameters of 14.90 m of Our Women Elite Triple Jump Athlete Named XIE Li-mei
【摘要】 采用文献资料调研和二维录像解析软件Peak Motus9.0、视频图像分析软件Dartfish4.0对我国女子三级跳远优秀运动员谢荔梅打破亚洲纪录的一跳14.90m进行录像研究分析,提供相关的关键运动学参数。研究结果表明:1)谢荔梅跳14.90m的最后两步步长为2.14m和2.35m,最后两步均速分别为9.30m/s;助跑水平最大速度为9.43m/s;2)三次起跳瞬时水平速度分别为8.39m/s、7.45m/s和6.67m/s,垂直速度分别为2.59m/s、1.73m/s和2.15m/s,三跳起跳角度分别为17°、13°和17.8°;3)三跳比例情况为第1跳38.7%,第2跳为27.7%,第3跳为33.6%。
【Abstract】 Through using the method of literature review and two-dimension video-tape analysis and two video-image software systems named Peak Motus 9.0 and Dartfish 4.0,this paper makes video research on the result of 14.90m of Xie Li-mei who is a women elite triple jump athlete and her result has broken the Asian women triple jump record.The result showed that:1.the length of last two strides was 2.14m and 2.35m.the average speed was 9.30 m/s of the last stride,the maximal approach velocity was 9.43m/s.2.the horizontal speed of three jumps were 8.39m/s,7.45m/s and 6.67m/s,the vertical speed were 2.59m/s,1.73m/s and 2.15m/s,three take-off angles were 17°,13°and 17.8°.3.the proportion of the three stages of jump were 38.7%,27.7% and 33.6%.
