One of the most important points in assessing the effectiveness of physical rehabilitation in children with scoliosis is the dynamics of the indicators of functioning of the cardiorespiratory and vascular systems. Purpose of the research: the scientific research is to study the effectiveness of the developed physical education program on the dynamics of changes in additional parameters of the functioning of the cardiorespiratory and vascular systems in school-age children with scoliosis at the age of 11-14 years. Materials and methods of the research. The bases for the research were specialized general sanatorium boarding school № 13 for children with scoliosis in OleksiyevoDruzhkivka, Donetsk region.The study was conducted among 19 children at the age of 11-14 years with scoliosis (9 boys and 10 girls). A comprehensive program of physical exercises for long-term rehabilitation of school-age children with spinal defects (scoliosis) has been developed. The research was based on the results of the impact of a comprehensive program of developed exercise technology on the leading indicators of physical performance, absolute and relative heart volume, stroke volume and minute blood circulation; cardiac index by PWC; MSC by heart volume; blood flow rate. The response of the cardiovascular and respiratory systems to the results of physical education was assessed by left ventricular capacity, oxygen pulse, minute blood volume, arteriovenous difference, Brelov’s shock index and vascular resistance. Results. The program of physical education has a positive effect on the functioning of the cardio-respiratory system, according to the definition of left ventricular capacity in children with scoliosis at the age of 11-14 years showed that the indicators in girls were statistically significantly higher than in boys. There was a general trend: an increase in the power of the left ventricular myocardium during exercise and its gradual decrease during rest, there was also a statistically significant increase in oxygen pulse at rest as in boys (12.24±0.06 vs. 9.29±0.05), and in girls (13.06±0.04 vs. 8.69±0.15) compared with the “background” value before exercise. Minute blood volume in boys was statistically significantly lower than the corresponding rate before exercise, while in girls – minute blood volume increased on the background of exercise, the rate of arteriovenous difference in girls was statistically significantly lower than the corresponding the importance of boys at rest, during exercise and at rest, as well as after exercise, there was a statistically significant increase in vascular resistance both at rest and during exercise and rest. At the same time, the rate in boys was statistically significantly higher than the corresponding rates in girls of this age group both at rest and during exercise and rest. Conclusions. Thus, a special program of physical education for children with scoliosis aged 11-14 years has a positive effect on the functioning of the cardio-respiratory system, according to the definition of left ventricular capacity and oxygen pulse. Determination of vascular specific resistance allowed to show the same gender distribution of the indicator before physical education activities (p>0.05). Thus, under load, the resistivity of the vessels decreased, and then increased again to the appropriate “background” values. Prospects for further research. The multidirectional in the quality changes in the dynamics of additional parameters of the cardiovascular and vascular systems that have been presented in the research, require the development of individual exercise programs to improve the physical performance of children at the age of 15-17 years with scoliosis
