AGE-RELATED DEVELOPMENTAL FEATURES OF HEMODYNAMIC INDICATORS IN YOUNG ATHLETES DURING THE FORMATION OF THE SPORTS RESERVE

Abstract

A systematic analysis was conducted on the age-related developmental characteristics of central and peripheral hemodynamic indicators in young athletes (ages 11–16) during the sports reserve formation stage. The study examined the dynamics across age groups of key functional indicators in athletes, such as heart rate (HR), systolic and diastolic blood pressure (BP), stroke volume (SV), and cardiac output (CO). The findings demonstrate the development of cardiovascular system economy under the influence of physical loads (physiological bradycardia and hemodynamic efficiency), and also substantiate the scientific and practical significance of early physiological monitoring in preventing chronic overstrain.
