Summary

Objective: to study the duration of physical work to failure and its «physiological price» in subjects with different directionality of pulmonary ventilation changes after training of hypoventilatical breathing in the background of physical exercises. Materials and methods: twelve young men who performed a test load on a bicycle ergometer to failure before and after training were examined. ^e ECG, pneumogram, spirometry parameters, arterial oxygen saturation level, and the duration of physical work to failure were recorded. ^e «physiological price» and parameters of hemodynamics were calculated. Results: after training of hypoventilatical breathing, depending on the directionality of the change in pulmonary ventilation, two groups of subjects were identified: «group 1» - increasing pulmonary ventilation and «group 2» - maintaining its baseline level. It was shown, that hypoventilation training had a different effect on the functional state of the subjects of the selected groups. After hypoventilation training, the duration of work to failure was increased in both groups, but only for subjects of the «group 2», the physical work was accompanied by an increase in the «physiological price» (p
