[Dynamics of hormones, sugar and electrolytes during hypodynamia according to blood biochemical indices].

Time-course variations in hormones, carbohydrates and electrolytes (specifically, cortisol, aldosterone, testosterone, T3, T4, sugar, potassium, sodium and chlorides) in blood of essentially healthy men, aged 19-59 years, kept for 30 days in a closed life-support system were measured. The hormones, sugar and electrolytes varied in a different manner. The subjects, aged 48-59 years, who performed regular exercises showed a higher stability of potassium, sodium and chlorides and a normalization of hormones by test day 30 in contrast to other groups of subjects.
