CONVENTIONAL RESPIRATORY REFLEX TO INCREASED RESPIRATORY RESISTANCE AS AN EXPERIMENTAL MODEL OF ADAPTIVE ACTIVITY

State Budget Educational Institution of Higher Professional Education “Ryazan State Medical University named after academician I.P. Pavlov” of the Ministry of Public Health and Social Development of the Russian Federation, Ryazan In the article it’s verified that conventional respiratory reflex to resistive load is the organism’s multicomponent reaction which can be used adequately as a model of adaptive human activity due to some methodical advantages: rapid reflex formation, relative strength, distinct quantitative evaluation criteria of components, relative simplicity of fulfillment of the methods. A step-like change in reinforcement of congenital respiratory reflex essentially rebuilts spatiotemporal structure of adaptive activity as well as its physiological cost.
