世界优秀男子三级跳远运动员三跳远度与成绩灰色关联分析——兼探讨我国运动员与世界优秀运动员之间的差距

Gray Correlative Analysis of the Performance and Length of Top Triple Jump Athletes——Research between the Gap of Chinese and Foreign Elite Atheletes

目的:通过对中外优秀男子三级跳远运动员的跳远技术与成绩进行分析,以期能为我国的教练员和运动员提供参考。方法:运用文献资料和灰色关联分析法,对世界优秀男子三级跳远运动员的三跳各跳远度与专项成绩进行综合分析。得出世界优秀男子三级跳远运动员的三跳各跳远度与专项成绩的关联度,并进行排序,分析各跳对专项成绩的影响程度。研究结果表明:第3跳远度是影响三级跳远成绩的最重要的因素,其次是第1跳,最后是第2跳;发现我国运动员在三跳比例、速度利用率多方面都与国外运动员有着一定的差距。建议:我国运动员在三跳中应充分利用水平速度,并获得较好的垂直速度,将速度利用率能力作为突破口,调整好三跳比例。

Purpose：This research wanted to analyze the triple jump technique in Chinese and foreign elite male athletes to provide the reference for Chinese coaches and athletes.Method：The test used the method of literature and gray correlation analysis to study the correlations between length in each jump and performance in world＇s best atheletes.The data were analyzed to get the impact factors.Results：The length of the third jump is the important factor to performance of triple jump,followed by the first jump,and finally the second jump.There is certain gap in ratio of three jump and rate of utilization of capacity.Suggesion：China＇s athletes of triple jump should take full advantage of the horizontal velocity and to obtain better vertical velocity and take the rate of utilization of capacity as a starting point,adjusting the proportion of a good triple jump.
