INTRODUCTION
The influence of coordinating ability parameter of motor accuracy on symmetry-asymmetry of the attacking and defensive technical actions fulfillment in combat sports in many cases provides technical actions mastering and conditions the result of a combat [1]. At the same time, motor abilities in difficult for coordination kinds of sport
provide dynamic, time and spatial parameters of motor action regulation [2]. During a boxing combat the force of gravity of different parts of the body creates tipping moments in terms of the lower extremities. In difficult suddenly appearing situations of a combat specially organized muscle load provides the skills of balance formation, connected with the parameter of coordination in
space and time. The ability to organize preparatory and counterattack actions during the combat provides steady balance and motor accuracy of their fulfillment [3]. A.A. Buchnev, L.D. Nazarenko
[4] studied the skills formation of technical actions spatial parameters control in judokas. The authors revealed that the skills of orientation in space in terms of interaction with the opponent during the combat are an important part of judokas' technical-tactical training control. One of the main components of orientation in space is an optimal direction of movement selection during the attacking or defensive techniques fulfillment.
Motor target accuracy, which is displayed during technical actions fulfillment in combat sports, is a difficult parameter of coordinating ability
[5]. In different motor technical actions accuracy is displayed in different way and has its own structure
[6]. For example, in fencing it is necessary to form accurate positions of a stand, attacking techniques at the initial stage of training [7].
Correlation connections analysis between judokas' stand and other parameters of an individual asymmetry profile showed significant differences between the athletes-beginners and qualified athletes [8]. Inaccurate fulfillment and spatial accuracy distortion in case of sudden situation change leads to false movements of the developed actions [7].
It means that the peculiarities of motor accuracy demonstration in coordinating structure should be based on its display study in terms of competitive activity [5, 8, 9].
MATERIALS AND METHODS
205 athletes took part in the initial research work. They studied at civilian and military higher educational establishments and their average age was 21,3±0,53 years-old, the experience of training was 9,21±0,69 years. There were no valid differences between the groups according to the mentioned indices. During data calculation the sampling included male (n=83) and female (n=39) athletes, who went in for different kinds of combat sports: sambo, judo, Greco-Roman wrestling and freestyle wrestling, hand-to-hand combat, mixed combats, kickboxing, sports karate, kiokusinkai,
boxing, taekwondo.
Athletes were divided into two groups. The first group included athletes with high level of motor accuracy parameter. The second group included athletes, who had a low level of motor accuracy display.
The numerical values were received according to the results of a special test use [10,11,12,13]. They estimates the display parameters of symmetry-asymmetry of the upper and lower extremities during technical actions fulfillment and motor-coordinating abilities according to 10-points scale. The received numerical values of the initial results according to these parameters in two groups of athletes were calculated with the help of Student's t-test for independent sampling.
We understand motor accuracy as a motor-coordinating quality. It provides more complete correspondence of a motor action with its spatial, time and power oriented parameters, depending on the definite situation and conditions [6].
RESULTS AND DISCUSSION
The table presents statistical differences of two groups of athletes. They go in for combat sports and differ in the level of motor accuracy parameter of motor-coordinating ability and the separate indices of extremities symmetry-asymmetry., They are displayed in a combat in terms of competitive activity. Motor accuracy parameter influence revealed valid differences (t=3,46-5,68, P<o,oi) according to the following parameters: dynamic, power characteristics of a movement; spatiotemporal characteristics. They are seen in the changing dynamic situation of a combat.
It proves that motor accuracy parameter is connected with other characteristics of motor-coordinating abilities and it is not isolated.
The influence of motor accuracy parameter on the separate parameters of symmetry-asymmetry of technical actions fulfillment revealed valid differences (t=2,50-3,0i, P<o,oi) according to the following parameters: preference to fulfill technical actions with the right hand; preference to fulfill technical actions with both hands; preference to fulfill kicks with both legs and change the right
stand for the left one and vice versa.
It proves that accuracy parameter influences symmetry-asymmetry of technical actions fulfillment. It means that while teaching these actions fulfillment it is necessary to develop motor-coordinating ability - "accuracy".
Motor accuracy influence on the separate parameters of symmetry-asymmetry of technical actions fulfillment: preference to fulfill technical
actions with the left hand; preference to fulfill technical actions with the right leg and preference to fulfill technical actions with the left leg. There were no valid differences between the groups (t=0,30-1,36, P<0,01), it only had the tendency to higher numerical values. It proves that accuracy parameter for symmetry-asymmetry of these technical actions fulfillment influences to a less degree.

CONCLUSION
We revealed the differences in private parameters of coordinating abilities of dynamic, power movement characteristics and spatiotemporal (speed, speed-up) on coordinating abilities of motor accuracy. It is seen in combat sports. Motor accuracy in combat sports is demonstrated in symmetry-asymmetry of technical actions fulfillment according to the following indices: preference to fulfill technical actions with the right hand, preference to fulfill technical actions with both hands; preference to fulfill kicks with both legs and the right stand change for the left stand and vice versa.
