从第29届奥运会看踏板精度和三跳比例对世界优秀三级跳远运动员成绩的影响

Effect of Touch-down Board Accuracy and Proportion of Three-jump on Performance of World Elite Triple Jumpers from the 29^(th) Olympic Games

通过文献研究法、运动现场录像法和视频图像分析法研究分析了第29届奥运会男女三级跳远决赛所有运动员有效跳次的成绩、踏板精度、三跳距离和比例特征。研究结果获得了踏板精度和成绩之间的相关关系,男、女运动员踏板精度的差异性,三跳距离和所占的比例特征,三跳距离和比赛成绩之间的相关关系,不同成绩阶段的三跳距离和比例特征,并得出了相应的研究结论。旨在对我国男、女三级跳远项目的更好发展提供理论上的支持和帮助。

By the literature research,the sport live-video and the video-image analyzing methodology,this paper presented the characteristics of every valid competition result and the precise touch-down board and the every jump distance and proportion of all the triple jump athletes who took part in the triple jump final match in the 29th Olympic Games,including man and woman.The results of paper showed the correlative coefficient of competitive result and the precise touch-down board,the precise touch-down board discrepancy of man and woman,three-jump distance and the proportion,the correlative coefficient of three-jump distance and the competition result,the characteristics of three-jump distance and the proportion in different phase of competition result.The corresponding research conclusions can be inferred base on these research results.The main purpose is to provide the theoretical basis and support for better development of our man and woman triple jump event.
