Systemic organization of human physiological functions in the process of achieving a sporting result

The article is devoted to the study of the mechanism's interaction of cardiorespiratory functions and gas exchange under the achievement of a given sport activity result of human's activity. The methodological basis of the study was the K.V. Sudakov concept of systemic quantization of behavior. In accordance with it, sports activities are discrete and can be represented as a sequence of system units - systemoquants. The study involved 9 healthy volunteers, regularly engaged in physical training. The testing with physical load was carried out under the control of electrocardiography and pneumography by used bicycle ergometer. Before testing the ergometer load power was set constant, and the physical load level, required by the experimenter, be provided for by changing the speed of the pedals rotation. There were measured the heart rate, breathing rate, amplitudes of waves and segments of electrocardiogram, blood pressure. The gas analyzer was used for assessing the level of oxygen consumption and carbon dioxide emissions. It has been established that each of the stages of the systemoquant of sport activity has its own "vegetative portrait", reflecting the degree of involvement of one or another physiological function in the system organization.
