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%。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%.
