Popis:	A relative constancy of the acrophases of human circadian rhythms of autonomic functions was studied. Quantitative assessment was performed for interdaily, interindividual, intragroup, intraindividual, and total changes in the acrophases of the circadian rhythms of 22 parameters of hemodynamics, heart rate control, thermal status, and salivary electrolyte levels under comfortable environmental conditions and during early adaptation to high-altitude hypoxic and hot desert conditions. A biological interpretation was given for different criteria of changes in the acrophases. Phase-constant and phase-shifting circadian rhythms were determined.
