It was demonstrated that a 3-day pressure chamber training may increase the maximum tolerable "altitude" at rest from 8,600-8,900 m (depending on the onset rate of hypoxia) to 9,600 m. After pressure chamber training the maximum tolerable "altitude" increased from 8,200 m to 9,200 m, when exercising in a bicycle ergometer at 200 kgm/min and continuously ascending at a rate of 20 m/sec. A similar antihypoxic effect was also provided by a 7-day high altitude adaptation. Using polarographic measurements of oxygen tension in the skin, it was found that adaptation to hypoxia induced a more pronounced oxygen decrease at high altitudes. This can be attributed to a more distinct blood redistribution, i. e., a better blood supply to the vital organs at the expense of peripheral tissues.
结果表明，为期3天的压力舱训练可使静息时的最大耐受“海拔高度”从8600 - 8900米（取决于缺氧起始速率）提高到9600米。在压力舱训练后，当以200千克米/分钟的功率在自行车测力计上运动并以20米/秒的速度持续上升时，最大耐受“海拔高度”从8200米提高到9200米。为期7天的高原适应也能产生类似的抗缺氧效果。通过极谱法测量皮肤中的氧张力发现，对缺氧的适应会导致在高海拔地区氧含量更显著地降低。这可归因于更明显的血液重新分布，即以牺牲外周组织为代价，使重要器官获得更好的血液供应。
