TO THE QUESTION OF PHYSIOLOGICAL MECHANISMS OF RESERVE OF THE SERVICEMAN BODY CAPABILITIES

A distinctive feature of the professional activities of military specialists is the need to perform training and combat training tasks in adverse, often unusual environmental conditions. In the course of the work, the significance of physiological mechanisms that determine the reserves of the body of a serviceman during exercise and hypoxia was determined. The contribution of the central nervous system, cardiovascular and respiratory systems in providing resistance to physical stress and hypoxia is analyzed. The role of testing physiological systems in the study of reserves in the military to clarify the effectiveness of their activities under the influence of adverse factors is clarified. The reserve capabilities of the body of a serviceman in response to physical exertion and hypoxia are determined by the capabilities of the central nervous system, cardiovascular and respiratory systems. Individual resistance to physical activity is determined by the peculiarities of the bioelectrical activity of the cortical part of the brain a reaction of the activity of alpha and beta2 waves. Individual resistance to hypoxia is determined by the characteristics of the reaction of cardiac activity, vascular tone, lower levels of oxyhemoglobin.
