Pulmonary respiration of human is the automatic control system of ventilation

Exercising is accompanied by large short-term accelerations of man body in space. However, pulmonary respiration control schemes presented in the literature do not consider the influence of external disturbing forces on chest wall of man. But the movement of the chest wall is the object of control in the system of automatic control of pulmonary respiration. We have put forward a hypothesis about the origin of the mechanical regulation of breathing circuit under the effect of the acceleration of the body as an external disturbance. The aim of the study is to investigate the interaction of autonomous, proprioceptive and mechanical circuits in the management of pulmonary respiration in physical exercise. The experimental data were obtained on the relationship of acceleration of the body and the structure of the respiratory cycles in physical exercise. On the basis of experimental data was designed a hypothetical scheme of automatic control system of pulmonary respiration in physical exercise.
