Description

The invention relates to medicine, namely to sports medicine, and is aimed at restoring the physical performance of athletes after maximum psychophysical loads.

The discovery of inert gases (He, Ar, Kr, Ks) predetermined the development of many modern industries: nuclear energy, astronautics, aviation and electronics. In the XX century, the first steps were taken to use inert gases in medicine. Scientists, in tandem with doctors, were able to find out that depending on the physicochemical properties of oxygen in combination with inert gases, as well as methods of their application, it is possible to purposefully influence various levels of regulation of vital body functions, including stimulating recovery processes in athletes.

Known methods for improving human performance, involving the use of therapeutic respiratory gas mixtures: medical oxygen, hyperbaric oxygenation, "mountain air", hypoxic oxygen-nitrogen, hypoxic and hyperoxic oxygen-helium mixtures (Kotz Y. M. Sports physiology. -M.: Physical education and sport, 1986. - pp. 121-166; Pavlov B.N. et al. Fundamentals of barophysiology, diving medicine, barotherapy and treatment with inert gases. - M., 2008. - S.369-388; Patents of the Russian Federation 2082451 from 27.06 .97, 2016564 from 07/30/94; 2104013 from 10/02/98; 2181278 from 20 .04.02; 2286128 dated 10.27.06. And others). Each of the listed breathing mixtures is used to solve various problems facing athletes and trainers: increasing (restoring) physical performance, increasing endurance, maintaining performance against the background of injuries in athletes, etc. The disadvantages of these methods are the need for long-term use (10-20 days) (normobaric and hyperbaric oxygenation, hypobaric or normobaric hypoxic training, hypercapnic training), short-term effect, the absence of a complex effect on the athlete's body with one mixture to increase performance for a long time.

Closest to the claimed invention is a method of increasing the health of a person after physical and psycho-emotional stress, described in patent No. 2289432, 12/21/2006. This source of information refers to a course of hypoxic-hyperoxic training, while the training includes 10 procedures, each of which consists of 6 hypoxic-hyperoxic cycles. The cycle is an alternation of five-minute normobaric hypoxic effects with 3-5-minute hyperoxic effects. The first 5 procedures hypoxic effects carry out a mixture with 11% oxygen content, the following 5 procedures hypoxic effects carry out a mixture with 10% oxygen content. Hyperoxic effects are carried out with a mixture with 30% oxygen content. If necessary, it is possible to carry out an additional 5 procedures, also consisting of 6 hypoxic-hyperoxic cycles with alternating five-minute normobaric hypoxic effects with a mixture with 10% oxygen with five-minute hyperoxic effects with a mixture with 30% oxygen.

The disadvantages of the prototype is that to determine the duration of the hypoxic and hyperoxic effects are not taken into account the individual characteristics of the human body. In accordance with the basic methods of oxygen-helium therapy for the rehabilitation of highly qualified athletes, the recommended session duration is 15 minutes.

A method is proposed that is devoid of the above disadvantages, moreover, it uses pre-prepared with a fixed percentage of oxygen and helium heated mixture. At the same time, training is carried out in hyperbaric conditions with an excess pressure of 0.03 MPa.

The technical result of the claimed method consists in restoring a person’s working capacity after physical and psychoemotional stresses due to hypoxic and hyperoxic exposure with heated oxygen-helium gas mixtures, which optimize the body’s temperature and increase the compensatory-adaptive capabilities of the body due to cyclic hypoxia and hyperoxia with a duration of exposure that is established individually according to the principle of biological feedback communication depending on the fitness of human growth.

The method is as follows.

An “Inhalit” apparatus is installed in the pressure chamber with a breathing machine and a heater with a mask. Outside the chamber there remain sources of artificial respiratory gas mixtures, medical operational control equipment, and a low-voltage power unit of the Inhalit type apparatus.

A person is placed inside a pressure chamber on a deck chair with an adjustable back angle.

First, the sensitivity to hypoxia is determined by hypoxic exposure lasting up to 10 minutes with a measurement of at least once every two seconds the heart rate (HR) and the content of oxyhemoglobin in arterial blood (SpO ₂ ). During the exposure, an individual minimum of Spo ₂ (SpO ₂ min) and a maximum heart rate (HR max) are recorded for each person.

Then, an excess pressure of 0.03 MPa is created in the pressure chamber and a breathing session of a hypoxic-hyperoxic gas mixture heated to 40-80 ° C is carried out, which is used as an oxygen-helium gas mixture. The duration of the session is 25-30 minutes. One session includes 5-7 cycles, each of which is an alternation of hyperbaric hypoxic exposure to a gas mixture with a volume fraction of oxygen of 6% and hyperbaric hyperoxic exposure to a gas mixture with a volume fraction of oxygen of 30%. Hypoxic effect is carried out until either an individual minimum Spo ₂ or a maximum heart rate is reached, depending on which event occurs first. Hyperoxic exposure is carried out until the initial values of SpO ₂ and heart rate are reached. The number of sessions is 8-10, spend them daily.

Thus, the principle of biofeedback is implemented when the hypoxic mixture enters the person through the external respiration system (SVD), which irritates the corresponding centers in the central nervous system from where the pulses arrive to the cardiovascular system (CVS), which is manifested by an increase in heart rate in response to a decrease in the content oxyhemoglobin in arterial blood. These parameters are recorded by the heart rate measuring unit and SpO ₂ with the subsequent transfer of these data to the control unit for the supply of oxygen-helium mixture. Based on these parameters, switching to the supply of a hyperoxic mixture is carried out.

The method was tested with the participation of athletes involved in swimming and fencing in the amount of 25 people with a skill level of 1 category, candidates and masters of sports. In the tests, a complex of standard clinical and physiological methods for assessing the functional state of athletes was used (Guide to practical exercises in human physiology. - Ed. By Prof. A. Solodkov. Training manual. M., 2006. - S.80-130).

A statistically significant effect of an increase in the maximum physical performance of athletes at a level of at least 5% was revealed as a result of using a single session of such an effect.

It has been established that as a result of the course of hypoxic-hyperoxic exposure to oxygen-helium mixtures, the indicators of perception, attention, memory, thinking, and the ability for complex coordination activity significantly increase. Moreover, the achieved level is maintained for at least 10 days.

The method is absolutely safe, including with repeated exposure to humans.

The invention is fully ready for use. Its implementation will ensure high results in sports.
