Integration of Functional, Psychophysiological, and Biochemical Processes in Athletes after Audiovisual Stimulation

详细

We studied intra- and inter-system structural interactions between functional, psychophysiological, and biochemical processes in athletes after audiovisual stimulation (AVS). We used multiple linear regression and correlation analysis after AVS to investigate the formation of new relations between the nervous, hormonal, cardiorespiratory, and metabolic systems. AVS training leads to an increase in physical working capacity (PWC₁₇₀) and in the number of its correlations, e.g., with the amplitude of alpha-rhythm, resting heart rate (HR), concentrations of thyroxine, phosphorus, glucose, bilirubin, and triglycerides, antioxidant status, and the level of life satisfaction, which indicates the elevation in inter-system integration processes at different functional levels. An increase in the number and effects of factors contributing to PWC₁₇₀ (chronoinotropic reserve, lung capacity, reaction of individual α-rate power depth, reaction to the moving object, and the concentrations of glucose, creatinine, bilirubin, and thyroxine) eventually resulted in higher PWC₁₇₀. This indicates that the rate of synchronization between the studied parameters increases under the influence of sensory impact, which results in the improvement of adaptive capacity and provides a lower cost of adaptation to physical loads at the competitive stage of sports training.
