The article presents the features of the parameters of heart rate variability of sportsmen of high qualification after the neurofeedback course of 15 sessions. Neurofeedback session performed according to the Protocol, improved spectral power in the alpha range electroencephalogram in lead С3А1. The study included 134 participants. By the method of lottery randomization 122 participants were assigned to theneurofeedback group and 12 participants were assigned to the placebo group.The normal distribution was observed among such parameters of heart rate variability as RRmin, RRmax, K30/15, medianbefore the intervention. It is established that the neurofeedback course caused a significant decrease in the values of such parameters as SDNN, CV, SD, variations. At the same time the neurofeedback course caused a significant increase in vegetative index of rhythm and stress index. Placebo effect combined with the increase in heart rate, decrease in the values of the mean, mode, median, RRNN of the cardiac intervals duration.
