Abstract

During the year (January, April, June, October), indices of cardiovascular system’s hemodynamics and reserve capacity were calculated for 35 men and 35 women aged 18–22 years born and constantly living in Arkhangelsk (640 north latitude). It was detected that during winter the cardiovascular system is in a state of functional stress both in men and women, the functional reserves also being reduced. The biggest number of atypical responses to standard physical loads was observed in men during winter reaching 31.4 % and in women in spring, up to 51.4 %.

Keywords

natives of the European North, hemodynamics, functional reserves, seasonal changes.
