Abstract
The study aims to assess the functionality of the cardiovascular system’s condition in athletes with hearing impairment who live in the North region. 22 higher qualification volleyball players (26.42 ± 6.75 y. o.) with hearing impairment who had lived in the North region for at least 10 years participated in the research. Based on 5-min RR intervals measured at rest, the authors examined the functionality of the cardiovascular system’s condition in athletes with hearing impairment. The statistical indicators of RR intervals and indicators of variation heart rate monitoring were evaluated. The study determined the indicators of variation heart rate monitoring and statistical indicators of heart rate variability in athletes with hearing impairment that were defined by increased parasympathetic regulatory effects combined with a moderate increase in ergotropic reactions of regulatory systems on heart rhythm modulation. Due to the centralization of heart rhythm management, intense physical activity causes a moderate tension of autonomic regulation mechanisms in some volleyball players with hearing impairment.
