This work evaluates human body resistance towards hypotoxic conditions of the Middle Ob region. The authors tested a group of university students to evaluate oxygen supply of the body and respiratory system resistance to hypoxia and took timed inspiratory (Stange’s test) and expiratory (Genchy’s test) capacity tests. The students were also aked to fill in special questionnaires to identify additional climatic risk factors of oxygen deficiency, such as smoking, chronic respiratory diseases, lack of exercise. The tests revealed gender differences in respiratory resistance to hypoxemia: values for male students were significantly higher than those for female ones. Male students’ average breath holding capacity values were the following: 39.5 ± 1.08 seconds at Genchy’s test, 51.9 ± 1.12 seconds at Stange’s test. At the same time, female students’ breath holding capacity was 30.7 ± 1.67 seconds at Genchy’s test and 43.7 ± 1.05 seconds at Stange’s test. Thus, values of male students are significantly higher than those of female ones. 45% female students and 26% male students had poor breath expiratory capacity, and 40.4% of girls and 28.9% of young men had poor results on Stange’s inspiratory capacity test. Smoking students and students lacking physical exercise showed low resistance to oxygen deficiency. More than 45% of the tested students engaged in additional physical exercise showed the ability to resist hypoxia without significant adverse changes in the respiratory system.
