HYGIENIC ASSESSMENT OF HEMODYNAMIC PARAMETERS OF
SCHOOLCHILDREN AND STUDENTS WITH DIFFERENT MOTOR ACTIVITY
LEVEL

We studied the functional state of the cardiovascular system in 997 schoolchildren of Ufa and 597
students of the Bashkir State Medical University with different levels of physical activity. All subjects
were divided into 3 groups depending on the level of physical activity: the first group (control) consisted
of 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 with
an average level of physical activity, who in addition to physical education classes independently engage
in physical culture: running, walking, outdoor games and daily morning exercises; the third group
consisted of schoolchildren and students regularly engaged in sports clubs and sections, having the
highest level of physical activity. The following hemodynamic parameters were calculated: systolic blood
volume, minute blood volume, pulse pressure, fatigue coefficient, blood circulation efficiency ratio, Robinson
index. The data obtained for each group were subjected to statistical analysis separately for males and
females in the age aspect. We have established the positive influence of regular physical education and
sports on the metabolic and energy processes in the heart, which in turn leads to an improvement in the
main indicators of the cardiovascular system. Thus, among schoolchildren and students regularly
engaged in physical culture and sports, significantly lower values of minute blood volume, blood
circulation efficiency ratio, endurance coefficient, Robinson index and high values of systolic blood
volume, pulse pressure were noted. The presence of reliable direct correlation of the weak degree of
physical culture and sports with the majority of studied hemodynamic parameters was revealed.
