摘　　要：目的探讨单兵增氧呼吸器在高原对移居青年体力作业效率的影响。方法对进驻海拔3700m 20天的12名青年,在佩戴与不佩戴单兵增氧呼吸器时分别用EGM-Ⅱ型踏车功量计做踏车运动,初始负荷功率为50W,每3min递增50W,以60rpm连续踏车至200W 3min后终止。用直线回归法计算每位受试者的PWC_(170)。结果不佩戴时PWC_(170)为(223.72±17.63)W,佩戴时PWC_(170)为(241.15±17.82)W,佩戴时较不佩戴时PWC_(170)明显增高,差异有显著性意义(P<0.05)。结论单兵增氧呼吸器能明显提高高原移居青年的心功能及做功效率。Objective To explore the effect of single-soldier oxygen-increased respirator on manual work efficiency of transmigrant at high altitude. Methods： 12 young soldiers who stayed at high altitude of 3700m for 20 days loaded exercise tests with the EGM- Ⅱ bicycle ergometer holding 60rpm with and without single-soldier oxygen-increased respirator. Power start from 50W, increase by degrees 50W per 3 minutes until 200W, then PWC 170 was counted use beeline regress. Results：PWC170 with and without single-soldier oxygen-increased respirator is（241.1 5 ±17.82 ）W and （223.72± 17.63 ） W, which has very significant difference （ P 〈 0. 05 ）. Conclusion： single-soldier oxygen-increased respirator can improve immigrants＇ manual work efficiencv at high altitude.
