Dynamics of indicators of human psychophysiology when using rebreathing hypoxic training method

The article deals with the study of the influence of interval hypoxemic training (IHT) by re-respiration or rebreathing on human psychophysiological factors. According to this method a subject takes three deep breaths of atmospheric air with complete exhalations in a gas storage bag. Then he breathes the breathing gas within three minutes. In this case as adaptogens are the decreasing concentration of oxygen (O2) and the increasing concentration of carbon dioxide (CO2) in inhaled air (hypoxia and hypercapnia). Such an IHT with the subjects led not only to the reliable increase in indicators of physical working capacity but also to the essential increase in indicators of the subject’s psychophysiological and functional shape: work memory increased, psychomotor indicators improved. Simultaneously, the man’s subjective time turned out to be some isolated independent indicator which was influenced neither by hypoxia, nor hypoxic training. IHT based on rebreathing may be recommended to be used in the army in the frame of the comprehensive physical training program in order to increase resistance to hypoxia.
