目的:探讨在高原服用富氧水对移居青年心肺功能的影响。方法:对进驻海拔3700m1年的10名青年在服用富氧水前和服用富氧水(每次500mL,一日2次)15天后分别用EGM-II型踏车功量计做坐位踏车运动,初始负荷功率为50W,每3min递增50W,以60r/min连续踏车至200W,3min后终止。用直线回归法计算每位受试者功率200W时的心率(HR)及血氧饱和度(SaO2),记录运动终止5min后恢复HR,按公式计算心功能指数。结果:服用富氧水15天后,心功能指数增高,功率200W时SaO2增高;功率200W时的HR和运动终止5min恢复HR降低,差别有非常显著性意义(P<0.01)。结论:服用富氧水能提高高原移居青年的心肺功能。
Objective: To investigate the effects of oxygen-enriched water on cardiorespiratory function in migrant youth at high altitude. Methods: Ten youngsters stationed at 3700m1 were enrolled in the treadmill exercise with EGM-II treadmill before using oxygen-rich water and taking oxygen-enriched water (500mL twice daily) for 15 days respectively. , The initial load power of 50W, 50W increments every 3min to 60r / min continuous treadmill to 200W, 3min after the termination. The heart rate (HR) and oxygen saturation (SaO2) of each subject at 200 W were calculated by linear regression. The HR was restored 5 minutes after the end of recording exercise, and the cardiac function index was calculated according to the formula. Results: After 15 days with oxygen-enriched water, cardiac function index increased and SaO2 increased when power was 200W. The HR at power 200W and the HR decreased 5min after exercise terminated, the difference was significant (P <0.01). Conclusion: The use of oxygen-enriched water can improve the cardiopulmonary function in young migrants from plateau.
