运用文献资料、数理统计等方法,对参加第18届世界杯足球赛所有运动员的年龄进行研究,结果显示:第18届世界杯足球赛运动员平均年龄为27.41岁,主力运动员平均年龄为27.72岁;随着竞技水平的提高,运动员平均年龄在增加,竞技水平越低,运动员平均年龄离散程度越大;各位置运动员年龄顺序为守门员>后卫>前卫>前锋,且守门员的年龄差距最大;大洋洲、欧洲、美洲运动员平均年龄大于亚洲、非洲运动员,不合理的年龄结构是亚非球队成绩差的因素之一。
The results show that the average age of the 18th FIFA World Cup soccer athletes is 27.41 years old and the main athletes’ average age is 27.72 years. With the help of literature, mathematical statistics and other methods, the age of all athletes participating in the 18th FIFA World Cup is studied. The average age of athletes is increasing, the lower the competitive level is, the greater the average age of athletes is. The athletes in each position are in the order of goalkeeper, defender, avant-garde and striker, and the goalkeeper has the highest age difference. Oceania, Europe and the Americas The average age of athletes is greater than that of Asian and African athletes. The unreasonable age structure is one of the reasons for the poor performance of Asian and African teams.
