Characteristics of pulse changes during muscular activity in physical education classes

Heart rate dynamics is an important criterion for assessing the functional state of a student, an athlete, therefore, the study of the cardiovascular system is an important issue of physical culture, physiology, sports medicine at a university and these issues should be important for a coach, teacher and doctor. Due to the activation of the sympathoadrenal system, which leads, on the one hand, to an increase in the main indicators of the circulatory system (heart rate, shock and minute blood volumes, systemic arterial pressure, circulating blood volume, etc.), and on the other hand, determines changes in vascular tone in organs and tissues and a complex complex of neurohumoral processes occurs, with the beginning of muscle work in the body.
