Features of sensomotoric reactions of young taekwondists at the stages of the competitive period

Relevance. The level of sensomotoric reactions development in taekwondo determines the speed of response to external stimulus, the advantage against the background of the effect of surprise during fights and characterizes readiness for competitive activities. Of particular interest is the study of sensomotoric activity in children 8-10 years of age, a sensitive age period regarding the development of coordination abilities, spatial response and proprioreceptive sensitivity. Insufficient knowledge of the dynamics of these functions formation in young taekwondists at the stages of the training period determined the relevance of this study. The purpose of the work was to study the mechanisms of somatosensory reactions in young taekwondists in the preparatory, competitive and restoration periods of sports activities. Methods. Fourteen young taekwondists were examined at the stages of the training period to have a latent time of simple motor reaction, the number of shock movements with the hand and foot, the time of single movement, the accuracy of measuring time intervals, and the maximum frequency of movement. Quantitative group comparisons were performed using Student's criteria for associated samples using Statistica 10. Results. The results of studies of young taekwondists sensomotoric reaction showed a tendency to slightly reduce the time of motor response at all studied stages, the absence of significant changes in shock movements and the time of single movement. Subjective perception of time found negative values against the background of an increase in values during the competitive period. The maximum frequency of movement increased significantly at all stages of the study. An increase in the level of functional lability and temporary stability of nervous processes in arose in competitive and restorative periods. An increase in minute rhythmic activity was accompanied by a decrease in psychomotor endurance. Conclusion. The obtained results are informative indicators of the coordinated activity of temporal and spatial parameters and improvement of the convergence of neuronal pathways of sensory and motor centers, which makes it possible to effectively monitor and adjust the training process of children 8-10 years old engaged in taekwondo at the stages of preparation for competitive activities.
