Studying the State of External Respiration in Adolescents Under the Conditions of The Republic of Uzbekistan

It has been established that the voluntary increase in lung ventilation during rest is carried out by students within a fairly wide range, both due to the acceleration of breathing and due to the increase in respiratory volume. Assessment of adolescent body reactions to muscle loads in sports activities revealed the presence of conditions of relative hypoxia and hypercapnia. This likely served as the basis for the formation of mechanisms for stable adaptation to changes in the body's internal environment while significantly increasing the effectiveness of pulmonary ventilation.
