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

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.
