METHOD FOR IMPROVING HUMAN BODY ADAPTATION CAPABILITIES Russian patent published in 2019 - IPC A61M16/00 A61M16/10 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to preventive and restorative medicine, and can be used if it is necessary to increase adaptability of the human body to the effects of physical loads and unfavorable environmental factors. That is ensured by a course of interval normobaric hypoxic-hyperoxic trainings (IHHT), the sessions of which consist of alternating phases of breathing with hypoxic and hyperoxic gas mixtures combined with physical loads and additional sessions of respiration with oxygen hyperoxic mixtures (RHM) with inert gases. IHHT sessions are carried out using preheated heated to temperature of 50 °C, measured in the cavity of the face mask, respiratory mixtures. Respiratory mixtures used are hypoxic, consisting of oxygen 8 vol%, CO₂ not more than 5 vol%, inert gases – balance, and hyperoxic gases containing not less than 25 vol%. oxygen, inert gases – balance. Respiratory phases of hypoxic and hyperoxic mixtures are alternated by a biological feedback signal on SpO₂ and heart rate (HR). Duration of IHHT course is not less than four weeks with frequency of one session of IHHT lasting 30 minutes a day, during which additionally performed is not less than three physical activities and two additional sessions of respiration with heated hyperoxic mixtures (RHM) of oxygen with inert gases identical to hyperoxic mixtures, used in IHHT. Preliminary by means of multistage bicycle ergometric test initial indices of body physical performance (PP) – PWC₁₇₀, maximum oxygen consumption V_O2max, rate of growth of oxygen consumption value ΔV_O2, anaerobic threshold AT, which are taken as basic ones. In rest during breathing with atmospheric air for 5 minutes, recording a cardiointervalogramm (CIG) with measurement of duration of R-R intervals with accuracy of 1 ms and calculating heart rhythm variability indicators, which are indicators of the state of regulatory body systems (RBS), which are taken as basic. SpO₂min HRmax boundary values are set for carrying out normobaric hypoxic test. Normobaric hypoxic test is carried out by breathing with a heated gas mixture containing 8 vol%, jxygen, inert gases – the rest, depending on the priority the values of SpO₂min or HRmax, with registration of CIG are achieved. RBS state values are calculated, and the RBS condition indicators with identical basic values are compared. Results are used to assign physical loads taking into account basic indicators of physical performance, boundary values SpO₂min, HRmax and composition of respiratory mixtures for the first course of IHHT, which is carried out before the second physical load, with registration of CIG. One of the additional RHM sessions is performed for 25 minutes after the first physical load, and the other one, with duration of 10 minutes, after the third physical load. Then, RBS values are calculated, comparative analysis of obtained RBS values with identical basic and by results prescribed physical loads, SpO₂min, HRmax boundary values, composition of respiratory mixtures of the IHHT session and RHM session modes for the next day, in which the comparative analysis of the RBS values is carried out with identical values obtained on the previous day. On the last day, the PP values identical to the base values are determined, the obtained indices are compared to the basic ones, and an assessment of the level of enhancement of adaptive capabilities of the human body is carried out as the values V_O2max, ΔV_O2, PWC₁₇₀, AT relative to basic ones.

EFFECT: method provides higher non-specific resistance of the human body with achieving long-term adaptation to extreme physical loads and adverse environmental effects by selecting a certain mode of action stages.
