为了研究100 m跑运动员体型与年龄变化趋势，为运动选材提供参考，运用文献资料研究、数理统计等方法，对百年来100 m跑男、女运动员年龄、身高和体重及其与成绩关系进行分析。结果表明，世界顶级100 m跑运动员不存在相对年龄效应，最佳竞技年龄逐年递增；百年来，女子运动员呈现高大化趋势，近10年来男子运动员呈现高大化趋势，相对BMI ，RPI与100 m跑成绩相关度更高，尤其对于女子运动员和近10年来男子运动员，即RPI大，体型高大的运动员更可能取得好的成绩。同时表明，我国100 m跑选材将对运动员身高提出更高的要求，最大步长与次最高步频结合将成为未来100 m跑运动员一种趋势和主流。%In order to study change trend of age and body shape of world high‐level 100 meter athletes ,and provide reference for sports talents selection ,this paper analyzes the relationship among age ,height ,weight and performance of 100 meter male and female athletes in one hun‐dred years with the method of literature review and mathematical statistics .The result shows that the high‐level 100m athletes don’ t exist relative age effect and best competitive age in‐crease year by year .The trend of female athletes'body size became bigger durning past 100 years and the trend of male athletes'body size became bigger during last 10 years .Comparing to BMI ,RPI and 100 meters have higher correlation ,especially for female athletes and men athletes in last 10 years .It also suggests that with bigger RPI ,shape taller athletes are more likely to get good performance and our 100 meters athletes'selection will put forward higher request in future .The most stride length and with sub‐highest frequency will become a trend and mainstream among 100 meter athletes .
