Influence of psychoemotional stress on the functional state of the neuromuscular system and the efficiency of sensorimotor activity of highly skilled athletes

Abstract

Purpose: assessment of the influence of the level of psychoemotional stress and the effectiveness of mental self-regulation on the functional state of the neuromuscular system and the effectiveness of the sensorimotor activity of highly skilled athletes specializing in complex co-ordination sports (on the example of diving). Material & Methods: study involved 14 high-class athletes (master of sport, international master of sport, honored master of sports) at the age of 15–30 years. To determine the psychophysiological properties of the nervous system of athletes, the diagnostic complex "Diagnost-1" are used. Electroneuromyography was performed on the neurodiagnostic complex "Nicolet Viking Select". For a differentiated assessment of the level of stress, the emotional state of the respondents and also for assessing the effectiveness of mental self-regulation, a technique to select colors was used. Result: interrelation between the effectiveness of mental self-regulation and adaptability, the intensity of existing stress, emotional stability and vegetative balance with electroneuromyographic characteristics, strength and functional mobility of nervous processes, the accuracy of reaction to a moving object and the ratio of the reactions of lead and lag, the efficiency of sensorimotor activity are identified. Conclusion: revealed interrelation of the effectiveness of mental self-regulation and adaptability, intensity of existing stress, emotional stability and vegetative balance with typological properties of the higher parts of the central nervous system and electroneuromyographic characteristics of athletes can have prognostic value and be used to optimize the sports development of promising young people.
