国际大赛获奖运动员的克托莱指数分析

Analysis of Quetelet index of winning athletes in international competition

目的：探讨克托莱指数与获奖牌的关系,为选择训练运动员提供参考.方法：以2008年北京奥运会,2010年广州亚运会和2012年伦敦奥运会的官方网站信息为基础,收集了5 797名（男3 071,女2 726）获奖者的年龄、身高和体质量并计算了他们的克托莱指数.结果：亚运会获奖者的年龄、身高、体质量和克托莱指数小于奥运会.在评价运动员时克托莱指数可代替其他指数.部分项目的获奖牌的等级与克托莱指数相关,但无规律.克托莱指数的聚类分析结果与项群分类不完全平行.结论：克托莱指数对选拔训练运动员有一定参考价值.

Objective： To study the relationship between Quetelet index and winning medal rank and to provide a reference for selecting and training athletes. Methods.. Age, stature and weight of total of 5 797 winning athletes （male 3 071, female 2 726） were collected on official website of the Olympic Games （Beijing, 2008~ London, 2012） and the Asian Games （Guangzhou, 2010） and their Quetelet index was calculated to investigate relationship between medal rank and Quetelet index. Results： The age, stature, weight and Quetelet index were smaller in the Asian Games than in the Olympic Games. Quetelet index was better than other indexes when it was used to evaluate athletes. There was a low correlation between winning medal rank and Quetelet index in some items but no rules. The result of cluster analysis was not completely consistent to classification of sport item-group theory. Conclusion ： Quetelet index for selecting and training athletes has certain reference value.
