FEATURES OF THE STATE OF HEMODYNAMICS OF STUDENTS DEPENDING ON THE AVAILABILITY OF SPORTS TRAINING
Abstract
The purpose of the study in this article was to study the state of the hemodynamic parameters of students, depending on the presence or absence of sports training. The study included the results of a cardiointervalographic study of 102 students (age 19–20 years), differentiated into students who regularly engage in physical activity and students who have virtually no physical activity. For ECG registration and analysis of hemodynamic parameters, including those characterizing heart rate variability, the sports testing system "Medical Soft" (variant "MS FIT Pro", Russia) was used. Standard hemodynamic parameters (blood pressure level, pulse rate, stroke volume, cardiac output, etc.), statistical and spectral indicators of heart rate variability, as well as an integral criterion of the state of microcirculation were used for monitoring. The data analysis was performed in accordance with the age standards formed by the equipment developers. The study allowed us to establish that the studied hemodynamic indicators and parameters of heart rate variability in the majority of student-athletes generally fit within the physiological age range. The trained group of individuals had a lower level of heart rate, a lower risk of arrhythmogenic events, increased sympathetic stimulation of the myocardium, a larger volume of blood vessels and arteriole tone. Consequently, students engaged in physical exercises have greater adaptive reserves and better training of the myocardium.
