CARDIOVASCULAR INDICATORS OF ATHLETES IN SOMATOTYPE-RELATED RESPONSE TO PHYSICAL ACTIVITY

Abstract

In order to achieve high sports results, a comprehensive study of the athlete’s body is necessary. The morphofunctional study is the most informative and accessible. However, the somatotype-related functional state of the cardiovascular system of athletes remains insufficiently studied. The purpose of the research: To determine the indicators of the cardiovascular system of athletes in response to physical exertion, depending on the somatotype according to Reese-Eysenck. An anthropometric and functional study of the cardiovascular system of 49 athletes of the highest sports skill engaged in freestyle wrestling at the Sakha Republic’s Center for Traditional Sports was conducted. The Reese-Eysenck index was used to determine the somatotype. Functional examination of the cardiovascular system included blood pressure measurement and pulse counting at rest, then 1 and 2 minutes after exercise. The exercise consisted of a full squat with arms outstretched with a frequency of 20 squats in 30 seconds. In order to determine the tolerance of physical activity, the Roufier index was calculated. The adaptive potential of the cardiovascular system is determined using the index of functional changes. Somatotyping by the Reese-Eysenck index among the examined athletes revealed that a significantly large proportion of the examined individuals had an athletic somatotype. In pyknics, significantly large indicators of body weight and the transverse diameter of the chest were recorded. A functional examination of the cardiovascular system with the use of physical activity revealed a significantly greater increase in systolic blood pressure after 1 and 2 minutes and heart rate 1 minute after physical activity in individuals with the pyknic somatotype compared with others. The analysis of the results of the index of functional changes of athletes depending on the somatotype revealed the stress of the cardiovascular system function only in athletes of the pyknic somatotype. The obtained results indicate that the training process should be selected individually, taking into account the somatotype of an athlete, since among pyknics there are people with stress of the cardiovascular system with good results of physical activity tolerance according to the Roufier index.
