The work was carried out on 36 clinically healthy young basketball players aged 17-21 years old, training in the basketball section for at least 3 years. The created control group consisted of 26 clinically healthy young men aged 17 to 21, who had not previously been involved in any kind of sports. In the study, the examined were subjected to ultrasound examination using an SSD-80 "Aloka" device (Japan) with an assessment of the morphological and functional characteristics of the heart. The statistical analysis of the obtained results of the study was carried out using a personal computer using the Student's t-criterion. Some signs of the development of left ventricular muscle hypertrophy were found in young basketball players. At the same time, the basketball players retained the optimum volume of the left cardiac ventricle. The youth basketball players also had a higher diastole rate compared to the control group. Regular basketball training can strengthen the body. They lead to an increase in the muscle mass of the left ventricle, which increases its functional potential and provides an optimal blood supply to internal organs.
