Adaptive chemoreceptor plasticity and reactivity of the cardio-respiratory system in athletes under hypoxic loads

An exploration of 110 healthy men (not involved in sports and athletes) with the use of hypoxic loads was carried out. It is established that the specifics of the regulation of gas exchange depend on the nature of training loads (aerobic or mixed), which are manifested in the parameters of chemoreflector reactivity, the pattern of external respiration, gas exchange and activity of the autonomic nervous system under hypoxic load. As sports qualifications grow, the mechanisms of intersystem integration of the functions of the cardio-respiratory system are improved, which is manifested in an increase in cardiorespiratory coherence. Key words: athletes, hypoxia, cardiorespiratory system, gas exchange of the body, chemoreceptor reactivity.
