Integration of Functional, Psychophysiological and Biochemical Processes in Athletes after Audiovisual Stimulation
We studied intra- and inter-system structural interactions between functional, psychophysiological and biochemical processes in athletes after audiovisual stimulation (AVS). By using multiple linear regression and correlation analysis after AVS, we observed the formation of new relations between the nervous, hormonal, cardiorespiratory and metabolic systems. AVS training leads to an increase in physical performance level (PWC170) and in the number of its correlations, e.g. with the amplitude of alpha-rhythm, resting heart rate, 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 effect of factors contributed 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 physical performance. This indicates that the rate of synchronization between studied parameters under the influence of sensory impact that resulted in improvement of adaptive capacity and provides a lower “price” of adaptation to physical loads at the competitive stage of sports training.
