Abstract

This paper analyses the results of a correlation analysis of haemodynamic parameters in 38 male skiers with the ranks of First- and Second-Class Sportsman aged between 18 and 22 years. Stroke volume, heart rate, cardiac output, myocardial efficiency index, myocardial stress index, left ventricular power index, and total peripheral resistance were determined 4 times a year (autumn, winter, spring and summer). It was found that not only the haemodynamic parameters, but also the connections between them change during the year. For instance, in skiers with sports ranks, stroke volume prevails in the structure of cardiac output, especially in autumn and winter, which indicates a significant chronotropic reserve of the cardiovascular system. Myocardial efficiency index is provided by the value of stroke volume. A correlation between myocardial efficiency index and left ventricular power index in skiers can be observed in autumn and, especially, in winter. The value of total peripheral resistance negatively affects cardiac output, stroke volume, myocardial stress index, heart rate, and left ventricular power index.
