The objective of this work was to study the influence of corrective and health-improving exercises on the functional characteristics of the cardiorespiratory system of adolescents residing in a megapolis before they developed any pathology. The health status of the children (n = 1760) was monitored using the "Health Navigator" technology; special attention was given to the initial state of the cardiorespiratory system and its dependence on the environmental factor. The proposed program of special corrective respiratory exercises in combination with physical endurance exercises was shown to improve the adaptive responsiveness of the cardiorespiratory system and correct the initial level vasoregulation.
