Optimization of the Functional State of the Cardiovascular System of Children Who Have Experienced the Stress of Military Operations

Abstract

Aim: To study the specific functional condition of the cardiovascular system in primary school-aged children who experienced stress from military actions. Design: Prospective cohort non-randomised study. Materials and methods. There were 730 children under observation: 239 children of the main group lived in the territories where active hostilities took place; the younger schoolchildren of the control group (491 children) lived in territories where military operations were not carried out. The functional state of the cardiovascular system was studied by calculating and determining the parameters of the Martinet–Kushelevsky sample. Results. The study showed that the recovery of heart rate after the Martinet–Kushelevsky test in younger schoolchildren who were in peaceful living conditions occurred faster than in children who experienced the stress of military operations (p < 0.05). The initial study of children who experienced the stress of military operations allowed us to establish not only a longer recovery time of blood pressure (p < 0.001), but also gender differences. The study conducted repeatedly, against the background of the integrated integration program, revealed a significant (p < 0.05) decrease in pulse blood pressure values in all subgroups. Conclusion. In younger schoolchildren who have experienced the effects of active hostilities, the ability of the cardiovascular system to recover after dosed physical activity is sharply reduced; the identified features of the functioning of the CCC in children must be taken into account during physical education lessons at school.
