通过运用SIMI Motion 3D运动图像解析分析系统对参加第11届全国运动会田径比赛男子三级跳远决赛的前3名运动员起跳前后技术进行解析研究。结果表明:中国优秀男子三级跳远的三跳比例表现为单足跳大,跨步跳小,最后跳跃基本合理,但中国优秀男子三级跳远运动员单足跳的水平速度损失较多;在跨步跳中支撑时间较长,身体重心腾起角度较小,以致使跨步跳距离比例过小;在最后跳跃阶段的着地速度、离地瞬间速度、身体重心的腾起角都不及世界优秀运动员。
Through the use of SIMI Motion 3D moving image analysis system, the top 3 athletes participating in the 11th National Games track and field final men’s triple jump were analyzed. The results show that the jump performance of Chinese elite male triple jump is single jump, small jump and final jump reasonable. However, the horizontal jump of Chinese elite male triple jump is more than the horizontal jump. Strut support time longer, the body center of gravity rise angle is small, resulting in step jump distance ratio is too small; in the last stage of the jump speed, ground instantaneous speed, body center of gravity rising angle less than the world’s best athletes .
