Development of the functional state of the respiratory system of secondary school students by means of recreational swimming

The article examines in detail the effect of recreational swimming on the functional state of the respiratory system of secondary school students. The anatomical structure of the respiratory organs, their functional reserves and the mechanisms through which swimming contributes to improving children's health are investigated. Swimming develops respiratory muscles, improves ventilation of the lungs and increases their volume, which in turn contributes to more efficient gas exchange. The results of empirical studies confirming the positive effects of swimming on the respiratory system and the general condition of students are presented. Regular swimming exercises not only strengthen the immune system, reducing the incidence of respiratory infections, but also contribute to increased physical endurance, which is reflected in the results in endurance tests. In addition, swimming has a positive effect on the psycho-emotional state of children, reducing stress and anxiety levels, which is associated with the effect of relaxation and achievements in swimming. Thus, swimming is an effective means of comprehensively improving the health of schoolchildren.
