为了了解大学生运动员体型与胰岛素敏感度的相关性,我们招募了320名大学生运动员与300名非运动员为受试对象,测量了其身高、体重、BIA体脂肪率,计算身体质量指数(body mass index,BMI),并检测理论空腹血糖、血清胰岛素、稳态模型评估(homeostasis model assessment,HOMA)值、糖化血红蛋白以及胆固醇数值。我们比较了大学生运动员和非运动员胰岛素敏感度与代谢指标,并推测了其关联性。研究发现,运动员的体重、身体质量指数与BIA脂肪率均显著的高于非运动员;运动员的空腹胰岛素以及HOMA都显著的高于非运动员。另以皮尔逊积差相关以及偏相关探讨与胰岛素相关的因子,发现无论有没有经过性别与年龄的校正,运动员或非运动员的肥胖指标(体重,身体质量指数与脂肪率)都与胰岛素敏感度指标(胰岛素,HOMA)呈显著正相关,说明大学生运动员具有较低的胰岛素敏感度,并且胰岛素敏感度随着肥胖指标的升高而下降。本研究结果为揭示运动员体型与胰岛素敏感度的相关性提供了一定的帮助。
Abstract：In order to understand the correlation between body shape and insulin sensitivity of university athletes,320 college athletes and 300 non-athletes were recruited as our subjects, and their indices of body composition(height, weight, bioelectrical impedance analysis(BIA) and body mass index(BMI)) and glucose metabolism regulators(fasting glucose, serum insulin, HOMA, Hb A1 c and cholesterol) were measured. We compared the insulin sensitivity and metabolic indices of university athletes and non-athletes, andspeculated their correlation.We found that the body weights, BMI and BIA of athletes were higher than those of non-athletes. In addition,fasting insulin and HOMA were significantly higher in athletes than thosein non-athletes. Besides, Pearson product-moment correlation and partial correlation were used to assess whether markers of body composition were associated with insulin sensitivity. Here we found obesity levels(body weight, BMI and fat percentage) were correlated with insulin sensitivity(insulin, HOMA and cholesterol) in both athletes and non-athlete groups no matter the gender and age had been adjusted or not. These results demonstrated that university athletes had lower insulin sensitivity, and the insulin sensitivity went down as the obesity levels went up. Our research provided some help for the reveal of correlation between athletes body shape and insulin sensitivity.
