緒論：運動選材視為是運動員科學訓練重要的一環，年齡、身高、體重和克托萊指數作為最基本的形態指標在羽球運動員選材和訓練計畫的製定方面具有重要意義。研究目的：對2020年東京奧運羽球運動員年齡與身體型態進行分析研究。研究方法：研究對象為2020年倫敦奧運羽球項目男、女單打前14強，男、女雙打與混雙前8強，男、女運動員合計各為38位。以單因子變異數分析（one-way ANOVA）各單項男、女運動員在年齡、身高、體重與克托萊指數的差異，並以薛費法(Scheffe)進行事後比較，各項統計考驗的顯著水準均定p≦.05。結果發現：此次代表我國參加羽球競賽項目的男、女運動員，其年齡與身體型態皆與本分析當前世界優秀羽球男、女運動員的最佳競技結果相近。建議加強科學化訓練，落實最大努力開發運動員的潛力，延長運動員的運動壽命，確保優秀運動員為國爭光，並且延續與拓展羽球運動成績。

Introduction: The selection of sports materials is regarded as an important part of the scientific training of athletes. Age, height, weight and Quetole index as the most basic morphological indicators are of great significance in the selection of badminton players and the formulation of training plans. Objective: To analyze the age and body shape of badminton players in the 2020 Tokyo Olympics. Research methods: The research subjects are the top 14 men's and women's singles, the top 8 men's and women's doubles and mixed doubles, and 38 men and women in total in the 2020 London Olympics badminton events. One-way ANOVA was used to analyze the differences in age, height, weight and Quetole index of male and female athletes in each individual event, and the Scheffe method was used for post-hoc comparison. The statistical tests were significantly different. The level is averaged p≦.05. The results showed that the male and female athletes who participated in the badminton competition on behalf of our country this time were similar in age and body shape to the best competitive results of the world's outstanding badminton male and female athletes in this analysis. It is recommended to strengthen scientific training, implement the best efforts to develop the potential of athletes, prolong the sports life of athletes, ensure that outstanding athletes win glory for the country, and continue and expand the performance of badminton.
