Abstract
The altitude resistance of albino rats was studied via measurements of their altitude threshold on the 3rd, 7, 15, 30, 45th days of their step-by-step acclimatization to highlands (Tuya-Ashu pass at an altitude of 3200 m), on the 3rd, 7, 15, 30, 45th days of their nonstep-by-step acclimatization at the Tuya-Ashu pass and on the 3rd, 7, 15, 30, 45th days of their altitude chamber training. The step-by-step acclimatization of animals included their 15-day exposure to an altitude of 2200 m and subsequent stay in lowlands where their altitude threshold was recorded on the 3rd, 10, 20 30, 40, 60, 80th days. The data obtained indicate that step-by-step acclimatization to highlands results in a more significant increase of the altitude resistance of the animal body and a longer maintenance of the resistance on return to lowlands.
