Hygienic Assessment of Hemodynamic Parameters Of Schoolchildren and Students With Different Motor Activity Level

Abstract

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.

Game method to increase students' motivation to engage in elective disciplines in physical culture and sports

“…The formation of students' social confidence among their peers and in communication with teachers was carried out, as noted in the studies of other authors [28]; the development of the legal foundations of gaming activities took place [30]. The skills and abilities of playing games were practiced, which they may need even in later family life in contact with children [32,34].…”

“…Outdoor games are an effective means of increasing youth motivation for physical activity. Scientific researches of Russian scientists reveal the peculiarities of the use of outdoor games in folk traditions [26][27][28][29][30][31], in classes with schoolchildren and students [32][33][34] and sports training [35][36][37]. The authors note that the use of the game method allows you to diversify the relationship PHYSICAL EDUCATION OF STUDENTS between those involved (colleagues and rivals), and the application of the rules contributes to the development of moral and ethical standards of behavior.…”

Efficiency of improving health of children and adolescents while staying in summer recreation center

“…Преобладающими остаются заболевания опорно двигательного аппарата, органов зрения, желудочно кишечного тракта, дыхательной системы и нервной системы [16; 17]. Двигательная ак тивность, экологические факторы, питание, умственная и психологическая нагрузка яв ляются основными факторами формирова ния растущего организма [18][19][20]. Известно, что при этом важную роль играют не только условия проживания и обучения, но и отдыха.…”
