目的　综述国外氧气预呼吸过程中进行体育运动以提高对减压病预防作用的科研工作进展。　资料来源与选择　主要资料选自公开发表的氧气预呼吸过程中进行体育运动以提高对减压病预防作用的文献。　资料引用　参考文献 16篇。　资料综合　氧气预呼吸过程中进行体育活动可以减少减压病发生率 ,这已为低压减压实验及数学模型初步证实 ,这种作用可能是因为体育运动能使肺通气量、心输出量及组织灌流增加引起排氮效率提高的结果。　结论　结合运动的氧气预呼吸可以缩短氧气预呼吸时间而保持预防效果 ,符合高空飞行及航天员出舱活动的需要 ,故此方法值得深入研究 OBJECTIVE To summarize the progress of scientific research on the exercise of oxygen during pre-breathing oxygen in foreign countries to improve the prevention of decompression sickness. Sources and Choices The main sources of information are selected from the published literature on oxygen pre-breathing exercises to improve the prevention of decompression sickness. References 16 references. Data synthesis of oxygen pre-breathing during physical activity can reduce the incidence of decompression sickness, which has been initially confirmed by low-pressure decompression experiments and mathematical models, this effect may be due to physical activity can make pulmonary ventilation, cardiac output and tissue Increased perfusion leads to increased nitrogen efficiency results. Conclusion Combined exercise oxygen pre-breathing can shorten the oxygen pre-breathing time to maintain the preventive effect, in line with the needs of high-altitude flight and astronauts out of the activities, so the method deserves further study
