Aim. The article deals with studying the effect of feedback training on the characteristics of brain bioelectrical activity. Materials and methods. 60 female non-athletes aged 18–20 years participated in the study. Sports training for improving the vestibular analyzer and proprioceptive sensitivity was conducted as well as feedback training with the data for ‘the projected center of mass position’ and ‘applied efforts’ parameters. EEG recording was conducted during the Romberg and Biryuk tests before and after the training course. Results. The specificity of the physiological mechanisms of various types of training, aimed at improving the vestibular analyzer and proprioceptive sensitivity, is reflected in the formation of special patterns of bioelectric activity of the cerebral cortex. Traditional training methods have the least effect on EEG characteristics, while biofeedback training is characterized by a more pronounced effect. Along with similar effects (the increased slow activity of theta and delta range, mainly in the frontal area of the cortex, and activation of high-frequency beta activity in the occipital leads), differences are also recorded. If training with the “projected center of mass position” parameter used as a BFB channel was accompanied by suppression of alpha-range activity, then training with the “applied efforts” parameter used as a BFB channel, on the contrary, increased the alpha activity in the occipital cortex. Conclusion. The parameters of bioelectrical activity of the cerebral cortex are informative when conducting biofeedback training and can be used to monitor its effectiveness and assess the physiological aspects.
