Neurophysiological indicators of the body after the use of the Pravilo health-improving machine

Aim. The paper aims to assess the effect of classes with the Pravilo health-improving machine on the neurophysiological parameters of the body. Materials and methods. The following methods were used during the study: analysis and synthesis of scientific and methodological literature, analysis of documentary materials, a method for assessing regulatory mechanisms and neurohumoral regulation of the heart, methods of mathematical statistics. 20 persons (10 males and 10 females) were examined, who were engaged in training sessions with the machine 2 times a week for 6-7 months. Results. A comparative analysis of the data from the initial period and after 6 months of regular classes with the Pravilo machine revealed changes in a number of indicators (increase in the power of the LF, VLF, Total wave spectrum), which indicate the body’s stress response. After 6 months, an increase in SDNN and RMSSD (standard deviations), as well as an increase in the spectrum of HF waves were revealed, which indicates the predominance of parasympathetic regulation. Conclusion. HRV data under stress (the beginning of a training session) demonstrate that there is an increase in the activity of the sympathetic nervous system and a slight decrease in activity and reactivity of the parasympathetic nervous system (HF, RMSSD), though AMo values remain the same. This indicates the centralization of adaptation in the initial period of training with the Pravilo health-improving machine. After 6 months of regular training, an increase in several statistical and spectral indicators was revealed, which indicates the predominance of parasympathetic regulation. The effect of sympathetic regulation is removed, which suppressed the activity of the autonomous circuit, which contributes to the fastest transition from the stress stage to the compensation stage during the development of the adaptation syndrome.
