目的：探讨渐进式低氧训练后急性低氧暴露对脑氧饱和度的影响。方法：以45名男性大学生为实验对象,采用近红外光谱技术测试其在6周实验期内,常氧常压、急性低氧暴露（模拟海拔4 800 m）、3周渐进式低氧训练（模拟海拔2 500 m、3 500 m、4 800 m）、再次4 800 m低氧暴露运动时脑氧饱和度、动脉血氧饱和度（SpO2）。结果：3周渐进式低氧训练显著提高脑氧饱和度和SpO2;急性低氧暴露运动中脑氧饱和度和SpO2相对有效下降值存在相关性（r=0.792,P〈0.01）。结论：3周渐进式低氧训练改善脑组织的氧合状况,产生耐缺氧适应;低氧运动时脑氧饱和度随血氧饱和度的下降而降低。

Objective：To study the effect of progressive hypoxic training during acute hypoxia exposure on cerebral oxygen saturation.Methods：Cerebral oxy-gen saturation and arterial oxygen saturation（SpO2）of 45 male college students were measured in different conditions,exercised at normoxia,acute hypoxic exposure（simulated altitude of 4 800 m）,three-week progressive hypoxic training（altitude control for 2 500,3 500,4 800 m）,again acute hypoxic ex-posure（simulated altitude of 4 800 m）during the experimental period by near infrared spectroscopy.Results：The three-week training in progressive hypox-ia significantly increased cerebral oxygen saturation and SpO2;the relative decline in value the effective correlation coefficient was 0.792（P〈0.01）between brain oxygen saturation and SpO2 during acute hypoxic exposure.Conclusions：The three-week progressive hypoxia training to improve the oxygenation status of brain tissue,resulting in hypoxia adaptation;cerebral oxygen saturation decreased with a decline in oxygen saturation during hypoxic exercise.
