Audiovisual Stimulation Modulates Physical Performance and Biochemical and Hormonal Status of Athletes

Abstract

We studied the effect of audiovisual stimulation training course on physical development, functional state of the cardiovascular system, blood biochemical parameters, and hormonal status of athletes. The training course led to improvement of physical performance and adaptive capacities of the circulatory system, increase in plasma levels of total protein, albumin, and glucose and total antioxidant activity, and decrease in triglyceride, lipase, total bilirubin, calcium, and phosphorus. The concentration of hormones (cortisol, thyrotropin, triiodothyronine, and thyroxine) also decreased under these conditions. In the control group, an increase in the concentration of creatinine and uric acid and a tendency toward elevation of lowdensity lipoproteins and total antioxidant activity were observed in the absence of changes in cardiac function and physical performance; calcium and phosphorus concentrations reduced. The improvement in functional state in athletes was mainly associated with intensification of anabolic processes and suppression of catabolic reactions after audiovisual stimulation (in comparison with the control). Stimulation was followed by an increase in the number of correlations between biochemical and hormonal changes and physical performance of athletes, which attested to better integration of processes at the intersystem level.
