Aim. The article aims to determine the functional characteristics of the cardiovascular system in adolescents and young males in combat sports depending on their body type. Materials and methods. Adolescents and young males of the yakut population (freestyle wrestlers and boxers) were examined. The indicators of 42 athletes were studied. Anthropometric and somatometric methods were used. The somatotype was determined by Pignet and Rees-Eysenck indices. The cardiovascular system was studied by the index of functional changes. Blood pressure measurements and pulse counts were performed before and after exercise. The following physical activity was proposed: extended arm squats with a frequency of 20 squats in 30 seconds. Statistical processing was carried out using the SPSS 17.0 software package. Parametric and nonparametric methods of statistical analysis were applied. Results. In terms of body mass index, 14.3 % of the surveyed persons had insufficient body weight, 85.7 % – normal body weight. Overweight and obesity in athletes were not detected. Only persons of teenage age had a body weight deficit. It was established that persons with a strong physique according to the Pignet index and a normostenic somatotype according to the Rees-Eysenck index possessed significantly larger reserve and recovery abilities of the cardiovascular system. Conclusion. The obtained morphofunctional characteristics can be taken into account when selecting athletes to achieve higher sports results
