Features of adaptation of external respiration system among the athletes specializing in military hand -tohand combat
The article describes the process of the adaptation of the external respiration system among athletes have been doing the military hand-to-hand combat for over two years and from one to two years, compared with the cadets of higher military educational institution who are regularly engaged in the general and professionally-applied physical training in higher school. The dynamics of indicators, characterizing the speed, volume and speed parameters of the external respiration system has been investigated: forced expiratory volume in one second (FEV1); forced vital capacity of the lungs (FVC); peak expiratory flow (PEF); volumetric flow rate in the middle of the expiratory maneuver: forced expiratory flow between 25% and 75% of forced vital capacity of the lungs (FEF25%-75%). It has been determined that the long-term adaptation in the military hand-to-hand combat goes through the stage of deterioration of pulmonary ventilation, followed by the significant increase in capacity of the external breathing apparatus, gas exchange and improvement of bronchial conductivity.
