Comparative Characteristics of Internal Physiological Changes in Man during Adaptation to Alpine and Desert Conditions.

摘要

A comparative study of physiological shifts in people when changing their residence showed that the adaptation to mountain as well as desert conditions proceeds in 'northerners' at a slower rate than in 'southerners'. Indices of the cardiovascular system, external respiration and their restoration period after physical stress are fairly analogous for 'southerners' and permanent residents in mountain and desert localities, while for 'northerners' different data had been noted. A relation between the adrenal cortex activity and temperature conditions was detected expressed by decreased activity of 17-ketosteroids due to high external temperature. In adaptation to mountain as well as to desert conditions 'southerners' show higher reserve potentialities. It appeared that in 'southerners' the adaptation process is faster and easier as compared with 'northerners'; nevertheless common features of physiological mechanism of adaption to external effects had been established.
