Intermittent normobaric hypoxia as a method of correction and prevention of functional changes in old age

The study involved men aged 60-65 years. The course of intermittent normobaric hypoxia (APG) was carried out for 3 weeks with breathing hypoxic gas mixture with 18-15-13-10% O2. Before and after the course, the reactivity of the cardiovascular system and blood system, physical performance were evaluated. It has been established that the course of APG increases oxidative metabolism, leads to a decrease in the level of sugar, total lipids and low-density lipids in the blood, an increase in the number of red blood cells, helps to reduce and stabilize blood pressure, increase physical performance of the elderly. The results of the study indicate the possibility of using APG as a method of correction and prevention of functional changes in the elderly. Key words: hypoxia, old age, blood, physical performance.
