Research of the Hand Motion Dynamic Characteristics of the Women Boxers with Different Types of Functional Asymmetry

Abstract

Purpose: to determine the features of the hand motionspeed characteristics of female boxers with different types of functional asymmetry during dynamic work performing. Material and methods Participants:50 highly qualified female boxers (masters of sports, world-class athletes). The study of boxer’s psychomotor functions was constructed according to a certain pattern. The motor component of the motional response was investigated with the help of a tapping test. The time of simple and two complex visual-motor responses was determined. The study was completed by determining the time of identification of visual stimuli with various degrees of complexity without a motor response. It was assumed that this would allow considering the visual-gnostic component in a “pure” form. Such a construction of the study made it possible to evaluate the contribution of each component of the psychomotor response to the speed of boxer’s response with different types of functional interhemispheric asymmetry (FIA) profile. Conclusions:Ambidexters perform work at a faster speed than right-handers in a convenient mode. In this case, their right hand is faster than the left. The total quantity of motions which have been made by left-handers was greater than that of right-handers and ambidexters (both on the right hand and on the left one). The speed characteristics of female boxers with different types of functional asymmetry in the accelerated mode were the same. The tempo stability in right-handers and left-handers is high, but worse than in ambidexters. Boxerambidexterswho use the right stance are in a better position than right-handed ones. Left-handed female athletes perform motions with greater speed than right-handed ones. Keeping the optimal tempo for right-handers and left-handers is worse on the right hand than on the left one. Maintaining an optimal tempo for ambidexters is worse on the left hand. Left-handed athletes are faster than right-handed ones.
