Development of new indicators that could be used as predictors of athletes’ successful sport performance is crucial. The examination of a professional boxer, world champion in the super heavy weight division, showed that parameters of the sympathetic and the parasympathetic regulation of heart rate could be used as such criteria. The bioelectrical activity of the heart was recorded by using a portable, wireless, single-channel amplifier, located on a special chest strap. It was found that increase of the parameter of parasympathetic regulation of heart rate and decrease of the parameter of sympathetic regulation of heart rate and the stress index may have a direct correlation with the successful competitive activity of a professional boxer.
