Before and after 24-hour water immersion test subjects performed a submaximal workload on a bicycle ergometer. Changes in their hematocrit, circulating plasma volume and fluid balance were compared with those during immersion. As a result, the test subjects were subdivided into two groups. For one group the workload was very hard; adaptation to immersion was accompanied by significant renal losses of fluid from the intra- and extravascular space. The bicycle ergometry test after immersion demonstrated a decrease of exercise tolerance combined with circulatory disorders. The other group showed a higher exercise tolerance; after immersion exercise tolerance remained high at the expense of the reserves that maintained optimal blood supply to the working muscles.
在进行24小时水浸试验前后，受试者在自行车测力计上进行次最大负荷运动。将他们的血细胞比容、循环血浆量和液体平衡的变化与浸水期间的变化进行比较。结果，受试者被分为两组。一组的负荷非常大；适应浸水伴随着血管内和血管外空间大量的肾脏液体流失。浸水后的自行车测力计测试显示运动耐力下降并伴有循环障碍。另一组则表现出较高的运动耐力；浸水后运动耐力仍然很高，这是以维持工作肌肉最佳血液供应的储备为代价的。
