论当今世界优秀田径运动员身高、体重和克托莱指数的项群特征

Sports Group Characteristics of Body Height, Weight and Quetelet Index of Today's WorldElite Track and Field Athletes

采用文献法、数理统计法（单因素方差分析、相关分析）、归纳法，以1996亚特兰大奥运会田径决赛前8名运动员为研究对象，探讨当今世界优秀田径运动员身高、体重和克托莱指数的项群特征，以揭示田径运动不同亚类项群及其分组项目运动员在上述3指标上的量值模式及特点。结果表明；当今世界优秀田径运动员的身高、体重和克托莱指数具有鲜明的项群特征。不同亚类项群及其分组项目运动员在上述3指标上不仅差异显著，而且其量值排序具有一致性。说明上述3指标可作为基础形态指标应用于不同田径亚类项群及其分组项目的科学选材。建议尽快建立中国田径不同亚类项群及其分组项目优秀运动员身高、体重和克托莱指数的常模标准，以提高我国田径运动项目选材的科学性。

Heights, Weights and the quetelet indexes of world elite track and field athletes were analyzed to find out the sports group characteristics of different track and field events. The objects of the study were the athletes who had ob-tained the final races of about 40 events at the 1996 Atlanta Olympic Games. The one-way ANOVA and correlation were used as methods. The results indicated that the characteristics of athletes of different events groups were obvious, and the numerical positions in the three indexes were unanimous in different sub-category of event groups and different events. It is suggested that model criterion of body height, weight and quetelet index should be set up for scientific selec-tion of elite track and field athletes in China.
