We studied the functional state of the cardiovascular system in 997 schoolchildren of Ufa and 597students of the Bashkir State Medical University with different levels of physical activity. All subjectswere divided into 3 groups depending on the level of physical activity: the first group (control) consistedof schoolchildren and students, which do not involve in sports outside the school and university programs,with the lowest physical activity compared with other groups; the second group included persons withan average level of physical activity, who in addition to physical education classes independently engagein physical culture: running, walking, outdoor games and daily morning exercises; the third groupconsisted of schoolchildren and students regularly engaged in sports clubs and sections, having thehighest level of physical activity. The following hemodynamic parameters were calculated: systolic bloodvolume, minute blood volume, pulse pressure, fatigue coefficient, blood circulation efficiency ratio, Robinsonindex. The data obtained for each group were subjected to statistical analysis separately for males andfemales in the age aspect. We have established the positive influence of regular physical education andsports on the metabolic and energy processes in the heart, which in turn leads to an improvement in themain indicators of the cardiovascular system. Thus, among schoolchildren and students regularlyengaged in physical culture and sports, significantly lower values of minute blood volume, bloodcirculation efficiency ratio, endurance coefficient, Robinson index and high values of systolic bloodvolume, pulse pressure were noted. The presence of reliable direct correlation of the weak degree ofphysical culture and sports with the majority of studied hemodynamic parameters was revealed.
