Health-Preserving Technologies in the Prevention of the Development of Functional Disorders of the Cardiovascular System in Pupils

Abstract

Introduction. In modern conditions there is a tendency of increasing number of children with functional disorders of the cardiovascular system, especially at the beginning of the studying process, that specifies the necessity of wide integration of HPT. Purpose. The evaluation of the role of the health-preserving technologies in the prevention of the functional disorders of the cardiovascular system among children of the primary school age. Materials and methods. An in-depth clinical and instrumental examination of 153 children aged 6–11 years was carried out before starting school, during study period and after graduating from elementary school. The health-preserving technology of Professor O.D. Dubogay, HPT "Learning in Motion", was introduced and actively used in the secondary school No. 287 in Kiev, (methodological manual "Integration of informative and moving activities in the system of education and training of schoolchildren", Oryani, 2001) where 65 children (the main group) were examined. While in the secondary school No. 3 in Boyarka, 88 pupils were taught according to generally accepted methods (comparison group). Results. When entering school, first-graders revealed a low level of functional capabilities of the cardiovascular system. Positive evidence of the HPT on the state of the cardiovascular system was revealed; the percentage of children with a high and higher than the average level of functional reserve of the heart (based on the Roufier test) after completion of the elementary school was 77.6% in the main group, and 8.4% in the comparison group; according to the clinically orthostatic test, the physiological reaction of hemodynamics to changes in body position is observed in 35.4% of the elementary school children and 21.5% in the comparison group. The main group the number of children with positive results of the Shalkov test was increased by 31.1% of, while in the comparison group it was decreased by 24.9%. Conclusions. High medical (Ke=8.1), social (Ks=0.75) and economic efficiency of HPT was proved, which substantiates its widespread introduction into the work of educational institutions for the prevention of the functional cardiovascular pathology.
