目的：研究国家优秀青少年铁人三项运动员身体形态、生理生化机能、运动素质与比赛成绩的相关性。方法：以22名国家优秀青少年铁人三项运动员为研究对象，测量其身高、体重，计算克托莱指数和BMI指数，静脉取血检测血常规、睾酮水平，训练过程中测试3000 m跑步和400 m自由泳成绩，所有数据均用Spss 9．0统计软件与比赛成绩进行相关性分析。结果：身体形态指标中，男运动员身高（ r＝-0．681，P＝0．030）、BMI （ r＝-0．695，P＝0．026）与比赛成绩具有显著相关性，并且体重（ r＝-0．783，P＝0．007）、克托莱指数（ r＝-0．778，P＝0．008）与运动比赛具有极显著性相关性，女运动员身体形态各项指标与比赛成绩均无显著相关性（P＞0．05）；男、女运动员心功能各项指标与比赛成绩均无显著相关性（P＞0．05）；男、女运动员睾酮水平（ r＝-0．733，P＝0．016；r＝-0．739，P＝0．036）与比赛成绩有显著相关性；男、女运动员血常规中 HGB （ r＝-0．760，P＝0．011；r＝-0．851，P＝0．032）、HCT （ r＝-0．788，P＝0．007；r＝-0．764，P＝0．037）与比赛成绩有显著相关性， RBC、WBC与比赛成绩无显著相关性（ P＞0．05）；运动素质中男运动员3000 m跑成绩（ r＝0．867，P＝0．001）与比赛成绩有极显著相关性，女运动员400 m 自由泳即刻心率（ r＝0．935，P＝0．002）与比赛成绩具有极显著相关性，其他各项指标与比赛成绩无显著相关性（P＞0．05）。结论：运动员的身体形态、生理生化机能、运动素质与比赛成绩均具有相关性，但相关性程度不同，身高、体重、克托莱指数、BMI、睾酮、HGB、HCT 、3000 m成绩等指标与比赛成绩具有显著相关性（ P＜0．05），心功能、RBC、WBC等指标与比赛成绩无显著相关性（P＞0．05）；运动员的身体形态、生理生化机能、运动素质与比赛成绩的相关性存在性别差异。%Objective :To study the national outstanding youth triathlon athletes body shape , physiological and biochemical function ,movement quality with the correlation of the perform-ance ,as to provide theoretical basis for triathlon athletes talent identification .Methods :Taking 22 national outstanding youth triathlon athletes as the research object ,by measuring the height ,weight ,calculation the Quetelet index and BMI ,venous blood test routine blood ,testos-terone levels ,training process to test the 3 000 m running and 400 m freestyle record ,and then all the data correlation analysis by SPSS 9 .0 statistical software with the performance .Results :body configuration index of male athletes height ( r= -0 .681 ,P= 0 .030 ) and BMI ( r=-0 .695 ,P= 0 .026 ) has significant correlation with the performance ,body weight ( r =-0 .783 ,P= 0 .007) and Quetelet index (r= -0 .778 ,P=0 .008) and has extremely signif-icant correlation with the performance .Female athletes body shape indicators has no significant correlation with the performance (P> 0 .05);Male ,female athletes cardiac function indicators has no significant correlation with the performance (P> 0 .05);Male ,female athletes testos-terone levels ( r= -0 .733 ,P=0 .016 ;r= -0 .739 ,P= 0 .036 ) has significantly correlation with the performance ;Male ,female athletes HGB ( r= -0 .760 ,P= 0 .011 ;r= -0 .851 ,P=0 .032) and HCT ( r= -0 .788 ,P= 0 .007 ;r= -0 .764 ,P=0 .037 ) has significant corre-lation with the performance in the routin blood ,RBC and WBC ,there was no significant corre-lation with the performance ( P> 0 .05 );Athletic male athletes in 3 000 m run scores ( r=0 .867 ,P= 0 .001 ) has significant correlation with the performance ,female athletes in 400 m freestyle instant heart rate ( r= 0 .935 ,P= 0 .002 ) has extremely significant correlation with the performance ,other indicators there was no significant correlation with the performance ( P>0 .05) .Conclusion :the athletes'body shape ,physiological and biochemical function ,move-ment quality and performance are relevant ,but correlation degree is different ,height ,weight , Quetelet index ,BMI ,testosterone ,HGB ,HCT ,3000m performance indicators and performance has significant correlation (P< 0 .05) ,cardiac function ,indexes of RBC and WBC ,there was no significant correlation with the performance (P> 0 .05);The athletes'body shape ,physio-logical and biochemical function ,movement quality and performance has related to gender differences .
