Abstract
The work is devoted to studying the influence of mountain hypoxia on the state of the students» cardiovascular and respiratory systems. The results of our research indicate that under conditions of hypoxia, the activity of the respiratory system in students significantly increases while the activity of the cardiovascular system slightly decreases. Thus, the cardiac rate at an altitude of 1,600 m was 72.8 beats per minute for female students and 71.0 for males, with 76.2 and 74.8 beats respectively at 170 m. In the midlands, the value of systolic pressure fell to 113.6 mmHg in girls and 110.8 in young men, with the plain indicators at 117.6 and 114.6. The rhythm of breathing in conditions of oxygen deficiency in the surrounding air does not change. The level of respiratory volume in female students at an altitude of 600 and 1600 m was 0.62 l (P <0.05) and 0.68 (P <0.02), with 0.46 at 170 m. In the midlands, the inspiratory reserve volume in girls was 1.93 l (P <0.02), and in the plains it was 1.74. The VC level at the maximum height was 3.92 l (P <0.05) in female students and 4.42 l in male, and at a height of 170 m — 3.46 and 4.06 l, respectively.
