The article discusses the features of neurovegetative heart rate support during an active orthostatic test, depending on the predominance of the type of waves in the total power spectrum of athletes with hearing disabilities specializing in acyclic sports. 26 male and female athletes, aged 18-30 years, with hearing disabilities, engaged in acyclic types of adaptive sports (basketball, curling), were examined. All the athletes surveyed were ranked into subgroups, taking into account the predominance of the type of waves in the total power spectrum. As a research method, rhythmocardiography recording was used using the Poly-Spectrum hardware and software complex from Neurosoft LLC (Russia) in two stages, 5 minutes each: the first stage was lying in a state of relative rest; the second stage was in the position of an active orthostatic sample. The results of the study. It has been established that athletes with hearing disabilities with different types of wave predominance in the total spectrum power at rest have varying degrees of vegetative reactivity to an active orthostatic test. The higher the initial voltage of the regulatory mechanisms, the less reactivity is observed in response to a change in body position in space. A lower strain of adaptive mechanisms is associated in athletes with hearing disabilities, as in healthy individuals, with the influence of a segmental regulatory circuit with a predominance of parasympathetic influences of the autonomic nervous system. At the same time, a significant number of athletes with hearing disabilities (38.5% of the total number of athletes surveyed) with a predominance of very low-frequency waves in the total power spectrum suggests that hearing deprivation (sensorineural hearing loss) leads to stress regulatory mechanisms both at rest and in response to changes in body position in space.
