Abstract
Purpose: determining peculiarities of speed characteristics of hand movements of female boxers with different functional asymmetry types during dynamic work performance. Material: 50 highly skilled female boxers (masters of sports of international class, masters of sports). The study of female boxer psychomotor functions was designed according to a certain scheme. The motor component of motor response was examined by means of tapping test. The time of a simple and two complex visual-motor responses was determined. The study was completed by determining the identification time for visual stimuli of various degrees of complexity without a motor response. It was assumed that this will allow to consider the visual-gnostic component in a "pure" form. Such a design of the study permitted to evaluate the contribution of each component of psychomotor response to the response speed of female boxers with different types of functional hemispheric asymmetry (FHA) profile. Results: For the first time, the psychophysiological indices of female boxers were obtained. Female boxers were conditionally divided into right-handers, left-handers and ambidexters. The differences of these groups of female athletes in psychophysiological indices were established. Conclusions: In convenient mode, ambidexters perform work at a high rate than right-handers. At that, their right hand is faster than the left. The total number of movements performed by left-handers is greater than that of right-handers and ambidexters (it concerns both hands). The speed characteristics of female boxers with different types of functional asymmetry in accelerated mode are the same. The pace stability of right-handers and left-handers is high, but less than that of ambidexters. Ambidexters who use the right-handed stance are at advantage than right-handers with right-handed stance. Left-handed female athletes perform movements with greater speed than right-handed ones. For right-handed and left-handed female athletes it is more difficult to maintain the optimal pace of the right than the left hand, whereas ambidexters have problems with maintaining the optimal pace of the left hand. Left-handed female athletes are faster than right-handed ones.

Summary
The increase in the level of achievements in modern sport places high demands on the development of qualities and capacities determining the success of sports activity. The study of functional asymmetry in boxing is of great importance for identifying prerequisites, which determine the peculiarities of motor development, mental and physical state of boxers. It is important for individualizing the process of athletes’ preparation [4, 20, 34]. It was assumed that this will allow to consider the visual-gnostic component in a "pure" form Such a design of the study made it possible to assess the contribution of each component of psychomotor response to the response speed of female boxers with different types of functional hemispheric asymmetry (FHA) profile. Biomechanical and biological surveys with the participation of athletes, the legislation of Ukraine on health care, the 2000 Helsinki Declaration, Directive No 86/609 of the European Society regarding people's participation in biomedical research were adhered to
