Features of the Visual-Motor Reaction of Young Volleyball Players and Its Impacton the Accuracy of the Attacking Blow

Abstract

Introduction.The high speed and accuracy of the visual-motor reaction are the basis for the formation of the precision of volleyball players' movements. However, the visual-motor reaction of young volleyball players and its effect on the accuracy of an attack strike has not been studied.Purpose.Establishing features of the visual-motor reaction of young volleyball players with the direction of the periphery of the vision during the visual perception of moving objects and their influence on the accuracy of the attacking blow, taking into account motor asymmetry.Methods and material. 66 femaile volleyball players (7-16 years old) were examined. Technical preparedness of 22 femaile volleyball players (14-16 years old) were researched. A computer-based visual-response program and an impact test were used.Results.The dependence of the motor action on the accuracy of the reaction to the object moving is shown.At binocular perception,7-9-year-old volleyball players are dominated by the processes of excitation both in the general hit and in the reaction to the irritants presented fromthe left and fromthe rightsides. Volleyball players 13-16 years demonstrated the balance of nerve processes.Inhibition processes prevailed for athletes 10–12 years old. Proximity to balance of nervous processes was observed for 13–16 year olds when perceived with the left eye. The results of the study showed the correlation of the accuracy of the reaction with the accuracy of the attacking blow in the binocular and monocular perception of moving objects.Originality.Data on sensorimotor reactions in volleyball have been expanded. Taking into account the versatile perception of moving objects.Conclusions.Sensory prerequisites for the formation of the accuracy of an attack hit of young volleyball players are considered. The accuracy of the attacking blow by the right (dominant) hand depends on the accuracy of the reaction to the object moving from above-below with binocular perception. The connection of the accuracy of the reaction to a moving object from above with the accuracy of the attacking blow to the left area of the volleyball court increases significantly with the perception of the left eye. The accuracy of the reaction to the moving object from the right-left is less significant for the accuracy of the attacking blow by the right (the dominant) hand compared with the reaction to the object moving from above-below.Keywords.reaction to a moving object, periphery ofvisual perception, motor accuracy, motor asymmetry, excitation and inhibition of the nervous system.
