HEART RATE VARIABILITY IN EVALUATION OF FUNCTIONAL STATE AND TYPESOF AUTONOMIC REGULATION UNDER CONDITIONS OF SPACE FLIGHT

摘要

A mathematical model on the base of heart raternvariability (HRV) analysis was created afterrngeneralization of the results of many HRV studies duringrnspace flights on orbital station "Mir", in model terrestrialrnexperiments and investigations in humans with differentrndegree of functional deconditioning [1]. The results ofrnHRV studies at orbital station "Mir" and InternationalrnSpace Station (ISS) showed that condition of nearly allrncosmonauts in the course of flight was not beyond thernscope of physiological norm. It was revealed a presencernof different types (classes) of autonomic regulation underrnconditions of space flight. Clearly denominatedrnindividual types of adaptation reactions, which are littlernchanged for several years, are formed in each cosmonaut.
