The article presents the results of studies on the influence of mountain hypoxia on the state of the students’ respiratory system. When exposed to oxygen deficiency, only the respiratory capacity of the lungs undergoes significant changes. For instance, the RC level in female students under the influence of hypoxia gradually increased in conditions of medium altitude, reaching the maximum value of 0.64 liters (P ˂ 0.05), and on the plain - 0.44 liters. The RC value in young men reached the highest value of 0.74 liters in mid-altitude conditions, and on the plains, it constitutes 0.56 liters. The highest respiration rate for young men of 18.2 movements per minute was noted at an altitude of 600 meters, and the lowest - 17.4 at an altitude of 170 m. The maximum level of respiratory capacity while inhaling in girls is 1.24 liters, detected at an altitude of 600 meters, and the minimum level of 1.18 liters is noted at 170 m. The value of respiratory capacity while exhaling among young men living in the Sharoi region increased to 2.32 liters, and for those from Grozny - 2.24 liters. The highest VC level in girls - 3.87 liters - was found in the middle mountains, and on the plains, it was 3.58 liters. The VC value in young men, gradually increasing, reaches the highest value under the conditions of the Sharoi region - 4.57 liters, and in Grozny it was 4.28.
