[Maximum oxygen consumption as a test of human resistance to hypoxia, hyper- and hypothermia].

Study of experimental results shows that physical work capacity if an adequate indicator of human tolerance to adverse environmental effects. Maximum oxygen uptake, being a measure of physical work capacity, can be used as a prognostic indicator of human tolerance and adaptive capability in a hypoxic, high or low ambient temperature environment. Increase in maximum oxygen uptake under the influence of training or adaptation to hypoxia is accompanied by increase in heat and cold resistance.
