Abstract
Aim: To study circulatory system functioning in elite skiers during adaptation to cold. Methods: Echocardiography, electrocardiography, recording of arterial pressure and electrochemiluminescent assessment of serum B-natriuretic peptide were performed to study the functioning of the cardiovascular system in 16 skiers during the period of preparation for the national competitions in different seasons. Results. Adaptive structural and functional changes in the cardiovascular system remain during seasons. At the same time, considerable seasonal differences in the functioning of the circulatory system were found. In winter, the subjects showed lower blood pressure, larger size of the left heart cavity, an higher rate of early blood filling of the left ventricle, transtricuspid blood flow, as well as the time of hemodynamics in the root of the pulmonary artery. In the rehabilitation period after exercise in skiers background levels of serum NT-proBNP in winter were about three times lower than in summer. Conclusion. The results have shown that the cardiovascular system of elite skiers during seasonal preparation for the competition is characterized by stable adaptive structural and functional changes. Adaptation to cold increases the influence of vagus nerve on the tone of resistive vessels, increases cardiohemodynamics and decreases basal secretory function of the myocardium in response to hemodynamic loads.
