Introduction. Increasing physical activity, especially during playing sports, causes a powerful activation of all systems in the body [1]. Prolonged avoidance of regular physical exertion is extremely dangerous, as it leads to depression of all organs, creating conditions for the development of pathology and shortening of the upcoming life [2]. Considering these circumstances, it is considered relevant to continue studying the effect of various physical activity options on the biological capabilities of all vital organs of the young body.
The purpose of the study is to clarify the cardiac parameters of young football players.
Methodology and organization of research. There were 16 clinically healthy young men aged 18-19 years who had regular football training experience for about 3 years (experimental group). The control sample included 15 clinically healthy young men of the same age who had never been interested in sports. Standard ultrasound equipment was used to assess cardiac parameters. Statistical processing of the numerical results was performed with the calculation of the Student's t-test.
The results of the study and their discussion. The EG football players have obvious functional advantages compared to the control group. Especially pronounced differences when comparing the groups of subjects were observed in relation to the morphofunctional parameters of the left cardiac ventricle. The value of myocardial mass in the group of football players was 17.1% higher than in the control group. The transverse dimensions of the left atrium and left ventricle during the onset of diastole in football athletes showed a tendency to be higher than in the control. The index of the maximum rate of myocardial relaxation in the posterior left ventricular wall in football players exceeded the control by 22.9%. The thickness of the posterior wall of the left ventricle exceeded that in the control by 13.1%. Their final diastolic volume was lower than that of the physically inactive by 7.3%. At the same time, the shock volume in both groups of young men did not differ.
Conclusion. Regular football training promotes the development of the heart muscle of the left ventricle. The capacity of its cavity and the state of its pumping function remain optimal and comparable to the control, and the rate of relaxation of the myocardium of the walls of the left ventricle in young football players increases functionally advantageously.
