RESUMO
Background: The mandatory swimming lesson in primary schools, equipped with swimming pools, was introduced without studying of its health-saving effectiveness. Objective: The purpose of this study was to evaluate the health status of pupils studying in schools with different organization of physical education lessons. Materials and Methods: Cross-sectional study was organized in two schools with different organization of physical education lessons. The experimental group (E) consisted of 408 children of 14 year of study (210 girls and 198 boys) who during one of the lessons of physical education were engaged in swimming in the school basin. Control group (C) consisted of 279 primary school children (210 girls and 156 boys) from a neighboring educational institution where all physical education lessons were organized in the gym. The health status was evaluated using classical method of complex assessment of the state of health with the subsequent assignment of each child to one of the health groups. Results: In result of evaluation of state of health there was established that among pupils from E group the proportion of boys with harmonious anthropometric parameters is higher (p<0.05), children from this group are stronger than C group (p<0.05). The prevalence of diseases of the musculoskeletal system and the eyes among pupils in E group was lower comparing to the C group (p<0.01). In the E group percentage of pupils assigned to health group I was significantly higher and lower for the II (children with some morpho-functional abnormalities) comparing to the C group. Conclusion: Organization of one mandatory swimming lesson per week in primary school has positive effect on health status of children.
