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.
Introduction. A distinctive feature of the modern lifestyle of children and adolescents is insufficient physical activity having a negative effect on their health. We conducted a physical activity survey for 997 schoolchildren and 597 students of the city of Ufa. Results. The results showed that 688 respondents (43.16%) did not do sport outside school or university. 272 people (17.06%) reported jogging and playing sports games on their own. 634 respondents (39.78%) attended sports clubs and sections on a regular basis. The survey demonstrated that physically inactive students and schoolchildren violated daily routine. Such schoolchildren spent significantly more leisure time on television viewing (52.78%) compared to their peers attending sports clubs (41.36%). The percentage of schoolchildren spending much time on the computer among those not doing sport was also higher (58.59% vs 41.47%). The same trend was observed in the students: 36.24% of the students not practicing sport spent most of their leisure time on the computer. Physically active students spent enough time outdoors as compared to those not doing sport (23.40% vs 11.15%). Conclusions. The surveyed schoolchildren and students revealed age and gender differences in sports patterns. The duration of training and the level of sportsmanship was higher in boys than in girls. We also observed the increase with age in the number and duration of training, as well as the level of sportsmanship. The health status analysis showed that the schoolchildren and students doing sport had significantly more harmonious physical development, while disharmonious physical development was more common among physically inactive persons. The pupils and students practicing sport regularly showed higher lung vital capacity, hand muscle strength, and a higher level of adaptation.
An important stage in the recovery of children and adolescents should be considered a summer health campaign. In order to make a comparative assessment of the physical development, state of health, and the effectiveness of the rehabilitation of schoolchildren in summer health organizations, a survey of 355 children (189 girls and 166 boys) was conducted. It is established that the most children are those with normal physical development. An analysis of deviations in physical development showed that there are no significant differences in the proportion of children with underweight and overweight. It was found that for most schoolchildren the level of physical development is average, while girls with this level were significantly more than boys, and among boys there were more children with a low level. It was noted that about half of the children have a second group of health, and the proportion of children with the first and third groups was approximately the same. Analysis of the effectiveness of recovery indicates that by the end of the shift, most children have significantly improved basic indicators of physical development. Thus, an increase in body length and muscle strength of the hands by the end of the shift was observed in half of the children, the lung capacity increased in more than 60 % of children. Positive dynamics of body weight was noted in 45 % of children. In general a positive healing effect was noted in 70.2 % of children.
The study of the features of the functional indicators of various systems of the student»s body during his studies at the university is due to the importance of the problem of forming the future healthy generation of the country. In order to study the functional state of the body of students with different levels of physical activity, 672 medical university students were examined (30.7 % of them were boys and 69.3 % of girls). According to the IPAQ questionnaire, the subjects were divided into three groups: with high, medium and low levels of physical activity. The study revealed that more than half of the students with normal body weight were in the group with a high level of physical activity, while there were more boys in the group with average physical activity, and girls in the group with high physical activity. It was found that among students with excess body weight, almost a quarter of them were in the group with a low level of physical activity. A similar pattern was observed in the distribution by gender. According to the main indicators of hemodynamics, it was found that the pulse pressure index was higher among students with high physical activity, which indicates good fitness. The indicator of the coefficient of efficiency of blood circulation was higher in students with a low level of physical activity, which indicates a faster fatigue of students in this group. When comparing the average values of the Robinson index, it was found that this indicator was higher among students in the group with a low level of physical activity, which indicates a weakening of the function of the cardiovascular system. The conducted research allowed us to identify significant differences in the groups due to different levels of physical activity of students.
