摘　　要：目的:调查世居藏族与移居汉族居民有氧运动能力差异并进一步探讨其影响因素。方法:随机选取西藏大学男性在校教职工和大学生107名(世居藏族61名,移居汉族46名)进行问卷调查、人体测量学(身高、体重等)及生理学指标(血红蛋白浓度、血氧饱和度等)测试;心肺功能仪结合递增负荷自行车测试VO2max。结果:世居藏族居民VO2max优于移居汉族居民(P<0.05);VO2max与CO呈中度正相关(R=0.73,P<0.05);多元线性回归分析结果提示世居藏族与移居汉族居民VO2max差异影响因素可能与体重、年龄、HRrest、Hb和CO相关(P<0.05)。结论:世居藏族居民有氧运动能力优于移居汉族居民,藏族居民具有较低的静息心率、较低的血红蛋白浓度和相对较高的心输出量。Objective The aim of the present study was to investigate the difference of aerobic exercise capacity between native Tibetans and immigrated Han Chinese residents,and further explore its associated factors.Methods There were 107 male teaching staff and college students were randomly selected from Tibet University(61 were native Tibetans and 46 were immigrated Han Chinese).A questionnaire survey,anthropometric(height,weight,etc.)and physiological measurements(hemoglobin concentration,blood oxygen saturation,etc.)were applied.The maximal oxygen uptake(VO2max)was measured by cardiopulmonary function instrument combined with incremental load bicycle as the indication of aerobic exercise capacity.Results VO2max of native Tibetans was better than that of Han Chinese(P<0.05);VO2max was moderately positively correlated with CO(r=0.73,P<0.05);Multiple linear regression analysis indicated that VO2max were different between native Tibetans and immigrated Han Chinese residents,and weight,age,HRrest,Hb and CO may be associated with the difference.Conclusion The results of the present study indicate that the aerobic exercise capacity of native Tibetans are better than immigrated Han Chinese.Furthermore,the native Tibetans had lower resting heart rate,lower hemoglobin concentration and relatively higher cardiac output.
