中国七项全能运动的灰色关联特征与训练决策分析

运用灰色系统理论研究了中国１９９２年七项全能前１０名运动员各单项成绩与总成绩的关联特征，结果表明，１００米拦和投掷项目具有较高的关联系数，而８００米和跳跃项目的关联系数较低，在此基础上，通过与２１届奥运会前８名成绩加以比较，分析了中国七项全能运动训练过程应采取的宏观决策。

Gray Relative Characteristics of the Chinese Heptathlets Sports and Analysis of Trainning Decision

Grey System theory is applied to the study of the relative characterisitics of individual event results and total results of the Chinese heptathlet first ten places athletes in 1992. The results show that there is a higher relative coefficient in 100m huddles and throwing events but a lower in 800m running and jump events. On this basis, compared with the results of the first eight places in the 24th Olympics Games, the macrodecision, which should be adopted during the Chinese heptathlets trainning processes is analysed.
