Abstract

During all four seasons of the year, we studied the cardiovascular system of 35 skiers aged 18–22 years and born in the European North of Russia. In autumn and winter, they showed increased systolic discharge and minute circulatory volume, decreased systolic and diastolic blood pressure as well as heart rate and general vascular peripheral resistance, which proves the adaptive reactions occurring in the cardiovascular system in those seasons to be efficient. Increased total peripheral resistance, myocardial tension index and adaptive capacity as well as decreased myocardial efficiency showed that the functional state of the circulatory system is lower in spring and summer.

Keywords

European North, skiers, circulatory system, seasonal dynamics
