世界男子400米栏比赛节奏的模式研究

运用SPSS软件对悉尼奥运会男子 4 0 0米栏前 8名运动员预赛、半决赛、决赛三个赛次的分段用时进行相关分析和回归建模 ;同时 ,对其栏间步节奏及过第 5栏、第 8栏的名次与最终名次进行相关分析。结果表明 :预赛、半决赛第 1、2段落的分段成绩与赛次成绩呈负相关 ,其余各段落除半决赛中第 5段成绩外 ,均与各赛次成绩呈显著正相关 ;各赛次过第 8栏时的名次与最终名次呈显著相关性 ;根据各赛次体力分配 ,各栏间步数随赛次的延伸有减少的趋势。最终建立的预测模型经方差检验效果高度显著。

A Research on the Contest Rhythm of World Man's 400m Hurdles

By the SPSS, the paper carries through correlation analysis and regression modeling on the split time of man's 400m hurdles, which involves preliminary contest, semifinal and final contest of the best eights in Sydney Olympic Games. At the same time, the paper carries through correlation analysis on their rhythm of stride pattern, the place when they clear the fifth and eighth hurdles and their final place in the competition. The result indicates that there is a negative correlation between the split time of the first and second sects the preliminary contest , semifinal contest and the total time of them. And there is highly positive correlation between the split time of the rest of every contest and the total time, expect the fifth sect of the semifinal contest; and prominent correlation between the place on the eighth hurdle and the final place of every contest. According to the allocation of body rotation in every contest, the number of stride pattern between every two hurdles takes on a decreasing tendency along with the extension of the contest. By the proof test of One way Anova, the effect of the forecasting model ultimately established is highly prominent.
