气象条件与北京国际马拉松比赛成绩的关系

利用1981～2003年北京国际马拉松比赛成绩资料和同期北京市观象台逐时或定时观测的气象资料。定量分析了气象条件与北京国际马拉松比赛男子平均成绩、优秀成绩、女子优秀成绩之间的相关关系，并简述了主要气象因子对比赛成绩的影响机理。结果表明：气象因素对比赛成绩影响最大值在9～12min之间；不同性别运动员比赛成绩对气象要素反应的敏感程度不同；男子运动员对气温反应最为敏感，女子运动员对风速反应最为敏感；从人类生物气象指数来看，舒适指数是男运动员比赛成绩的最有效指示器，风冷指数是女优秀运动员比赛成绩的较好指示器。

Relationship between Weather Conditions and Athletes' Performance in Beijing International Marathon

By means of the data on athletes' performance in Beijing International Marathons from 1981 to 2003 and the daily or hourly meteorological data during the same time period,the relationships between athletes' performance in the marathons(both men and women) and weather conditions were analyzed quantitatively.The results show that weather factors have a great influence on the athletes' performance in the marathons: about 9 to 12 minutes.The correlation between temperature and athletes' performance is significant.The higher the air temperature is,the worse the performance.Drizzle benefits for acquiring better results.The comfort index is a good indicator of marathon performance for men athletes,and the wind-chill index for women.
