本文综述了两种静息低氧应用模式：间歇性低氧暴露(IHE)，即在持续60-90分钟的训练中，间歇性低氧暴露5-6分钟，与室内空气交替呼吸4-5分钟；或长期低氧暴露(Phe)，常压或减压低氧，每天长达3小时。使用IHE的低氧通常在12-10%的范围内，相当于海拔4000-6000米。常压或低压低氧和Phe对应的海拔4000-5500米。应用IHE的六项研究中的五项和使用Phe的所有四项良好对照研究都不能显示在14-20天的暴露后，这些低氧暴露方式对海平面表现的显著改善，除了游泳运动员，在Phe结合随后的逐渐减少的情况下，可能会有轻微的改善。没有直接或间接证据表明，IHE或Phe引起任何可能与提高海平面运动成绩有关的重大生理变化。因此，不建议将IHE和Phe用于在海平面上举行的比赛的筹备工作。
Two modalities of applying hypoxia at rest are reviewed in this paper: intermittent hypoxic exposure (IHE), which consists of hypoxic air for 5-6 min alternating with breathing room air for 4-5 min during sessions lasting 60-90 min, or prolonged hypoxic exposure (PHE) to normobaric or hypobaric hypoxia over up to 3 h/day. Hypoxia with IHE is usually in the range of 12-10%, corresponding to an altitude of about 4000-6000 m. Normobaric or hypobaric hypoxia with PHE corresponds to altitudes of 4000-5500 m. Five of six studies applying IHE and all four well-controlled studies using PHE could not show a significant improvement with these modalities of hypoxic exposure for sea level performance after 14-20 sessions of exposure, with the exception of swimmers in whom there might be a slight improvement by PHE in combination with a subsequent tapering. There is no direct or indirect evidence that IHE or PHE induce any significant physiological changes that might be associated with improving athletic performance at sea level. Therefore, IHE and PHE cannot be recommended for preparation of competitions held at sea level.
