摘　　要：目的了解长期驻高原军人有氧运动训练后机体心肺功能指标的变化。方法长驻海拔3600 m高原某部士兵32人,平时身体健康,能完成各项军训课目,体能测试达标。本次测试项目为3 km徒手越野长跑,于长跑前静息状态和长跑后现场测定受试者心率(HR)和血氧饱和度(SaO2)。结果运动后,受试者HR较运动前显著增加(P<0.05),平均增加幅度为53.0%;SaO2较运动前明显降低(P<0.01),平均降低幅度为3.2%。结论长期驻高原人员均获得了稳定低氧习服,表现为亚极量有氧运动时HR增高,SaO2无剧烈变化。Objective To investigate the changes in the cardiorespiratory functional parameters of soldiers garrisoned at high altitude of 3,600 meters after aerobic training. Methods The subjects were 32 soldiers garrisoned at the altitude of 3,600 meters who were healthy and able to complete every military training courses and met the examination standards. Their heart rate （HR） and blood oxygen saturation （ SaO2 ） were detected before and after the 3,000 km unarmed cross - country running. Results After the running, the HR of the subjects increased significantly compared with that before the excise （ P 〈 0. 05 ）, and the average increasing proportion was 53%. While the SaO2 decreased significantly（ P 〈 0.01 ）, and the average decreasing proportion was 3.2%. Conclusion Personnel garrisoned at the high altitude for a long - term have obtained stable hypoxic acclimatization, and the manifestations include the increase of HR but less decrease of SaO2 after submaximal aerobic exercise.
