Abstract
The purpose of the work is to determine the level of functional state of the cardiovascular system of children aged 11.12 years. Materials and methods. The study of functional indicators of the cardiovascular system in children (128) of two age groups (11 and 12 years). Physiometric parameters that characterize the functional state of the cardiovascular system, blood flow organs - heart rate (heart rate, beats per minute), systolic (ATC, millimeters of mercury), diastolic (ATD, millimeters of mercury) were measured directly. The Robinson's index was used as an indicator of the functionality of the cardiovascular system. Determination of the adaptive potential of the cardiovascular system was used as an integral indicator of the level of physical condition of children. Research results. The percentage of those who are dominated by the sympathetic nervous system and there is a shift towards sympathetic regulation in 12-year-old children is 13.3% and 16.7, respectively. Of the total number of subjects in 11-year subjects can be found such a large number (about 35.5% and 8.8% of students with sympathetic regulation and strong dominance of the sympathetic system), which can further lead to reduced functional capacity and the body. Indicators of the state of regulation of the cardiovascular system of children 11 and 12 years are at a level "below average". Comparing the percentage of schoolchildren in terms of adaptation capacity in groups 11 and 12 years, it was found that the largest number in the percentage of children with "unsatisfactory adaptation", which corresponds to unsatisfactory adaptation to environmental conditions while reducing functionality, in the group of 12 years (76, 67%) The number of children with unsatisfactory adaptation among 11-year-olds is 44.32% less. Conclusions. The results of the calculation of the Robinson index showed that in both groups of children 11 and 12 years of age the functional capabilities of the cardiovascular system are at a level "below average", and in children 12 years of age they are slightly lower. The average indicators of adaptation potential of the first group of 11-year-old children indicate the stress of adaptation. In the second group of 12 years, the level of adaptive capacity decreases sharply, it corresponds to unsatisfactory adaptation. The obtained research results are also a confirmation of the negative dynamics of the functional state, reserves and regulation of the cardiovascular system in the studied children. In order to improve the functional state of the respiratory system of schoolchildren, it is necessary to reduce the impact of hypodynamics, the impact of health technology, health programs.
