摘　　要：目的通过平板运动试验,分析比较中青年肥胖人群身体功能的相关指标。方法在笔者医院体检中心体检的健康人群中选出195名志愿者(18～59岁),根据BMI指数分为正常组和BMI轻、中、重度增高组,用Bruce极量运动方案对每一个受试者进行极量平板运动试验。通过对每一个受试者的运动持续时间、极量心率、运动终止即刻代谢当量值(MET)、身体活动评分、RPE等指标分析,对结果进行多元回归分析,得出极量运动持续时间的回归方程。结果到达极量运动时间的多元回归方程:y=166.947+45.433x1-4.087x2-0.696x3-0.178x4+0.452x5,x1为METS,x2为极量RPE,x3为BMI,x4为极量收缩压,x5为身体活动评分,校正r2=0.932,(P<0.01)。结论数据表明肥胖人群身体机能各项指标与正常对照组均有明显差异,其原因在于他们之间运动耐量和体重的差别。Objective To analyze and compare related indicators of physical function of young and middle - aged obese people by treadmill exercise test. Methods We selected 195 healthy population volunteers （ 18 -59 years） form physical examination in our hospi- tal medical center. According to the BMI index, the people is divided into normal group and BMI light, moderate and severe groups in- creased. We chose maximal treadmill exercise test for each subjects with Bruce maximal exercise program. The maximal exercise duration of regression equation can he resulted from the multiple regression analysis of each subject＇s exercise duration, maximal heart rate, exer- cise immediate termination of metabolic equivalent values （MET） , physical activity score, RPE and other indicators. Results Time to reach maximal result of multiple regression equation： y = 166. 947 ＋ 45. 433 x1 - 4. 087x2 - 0. 696x3 - 0. 178x4 ＋ 0. 452 x5, x1 for the METS, x2 for the most amount of RPE, x3 for the BMI, x4 for the maximal systolic blood pressure, x5 for the physical activity score, cor- rected r2 = 0. 932, （ P 〈 0.01 ）. Conclusion Data show that obese people with normal body function indicators showed significant differ- ences in the control group. The reason lies in the differences of exercise tolerance and the weight.
