    Abstract:
    Fourteen airworthy men, aged 19-20 yrs., participated in the experiments aimed at studying a prognostic significance of biochemical and hormonal parameters in evaluation of human tolerance to acute hypoxic hypoxia. Altitude chamber experiments were performed to study the tolerance to hypoxia by "ascending" the test subjects to an altitude of 6 to 7 km. It is found that under extreme hypoxic environments, of particular significance is an individual strategy of the adaptive responses and primarily an activity and adequacy of mobilization processes of energy resources in the preliminary and initial stages of an exposure. Of great value are the potential causes for maintaining the vascular tone. The use of a proposed discriminant function analysis for evaluating and predicting the tolerance to hypoxia is recommended.
