This article analyzes the indicators of stroke volume of blood, related to body weight. It should be noted that this value is an integral indicator of the activity of the heart, and depends on the heart rate, and also affects the minute volume of blood circulation. It is known that the value of SEC at rest in the process of growth and development of the body increases. We studied the magnitude of the stroke volume of blood, relative to body weight in boys engaged in Greco-Roman wrestling in the annual cycle of training and with different length of service. The results of the study can be used by trainers as an additional criterion for assessing the level of physical fitness and the effectiveness of the training process.
