The effect of hypoxic training in an insulating gas mask on increasing the body’s resistance to the influence of extreme conditions of professional activity

Relevance. Currently, studies aimed at increasing the resistance of the respiratory system to hypoxic loads are relevant both for clinical, rehabilitation medicine, and for medical and psychological support of specialists who carry out their professional activities in extreme conditions.

Intention – To evaluate the long-term effects of hypoxic training in a filter gas mask on the functions of external respiration.

Methodology. A spirometric assessment of changes in the functions of the external respiration system and an analysis of physical performance were carried out in two groups of students, including 50 people each. The first group used filter gas masks during physical exercises for hypoxic training, and the second group performed similar loads without gas masks.

Results and Discussion. In a group of students using gas masks during physical exercises, vital capacity of the lungs statistically significant increased in the middle and end of the academic year. Besides, 100 meter race time and numbers of repetitions when lifting the body from the prone position during examinations in the middle and end of the academic year indicate better fitness of students who used gas masks during physical exercises.

Conclusion. The use of a filtering gas mask as a hypoxicator when performing exercises during the academic year significantly increased functional reserves of the body, in particular vital capacity of the lungs and the physical fitness.
