[Effect of different schedules of motor activity on the processes of human adaptation to high-altitude conditions].

Responses of external respiration, hemodynamics and blood were studied in 12 test subjects during their step-by-step adaptation to altitudes of 2200 and 3200 m. The test subjects were subdivided into two groups who were exposed to different schemes of motor activity--free motor activity and diminished motor activity during bed rest. The results indicate a direct relationship between positive adaptive reactions of physiological systems of the human body and motor activity.
