The purpose is to develop the evaluation scales for the technique of the right straight blow from the left guard based on the analysis of the kinematic structure of the movements of high qualified athletes specializing in the hand-to-hand combat. Methods. Theoretical – to determine the relevance of the problem of forming the technique of motor actions in the hand-to-hand bought; empirical: pedagogical observation as a method of empirical level of research – for familiarization with the process of organizing training sessions; registration of the kinematic characteristics of the technique of the right-hand straight blow from the left guard was carried out using the marker system of registration and analysis of motions Qualysis, which allowed to record the data in three-dimensional space. The shooting frequency was 100 frames per second. The measurement error in determining spatial indicators was 1 millimeter per 1 meter of cubic space, the measurement error in time indicators was 0.01 seconds, ensuring high accuracy of registration of kinematic characteristics of athletes’ motor actions. Methods of mathematical statistics were used. The technique of performing the studied motor action of twelve high qualified athletes was registered within the research. Results. We used the following algorithm to evaluate the kinematic structure of basic impact motions techniques in hand-tohand combat. First, we chose a biomechanical indicator that can be used as a criterion for performance of the impact motion. As in has been known from the scientific and methodical literature, impact force is used as a criterion for the effectiveness of impact actions in most cases. However, our research did not use dynamometric devices that can register impact force. Therefore, we used the maximum velocity of the impact biolink as a criterion for impact effectiveness, which, according to literature sources, has a close correlation with impact force. Secondly, with the help of correlation analysis, informative parameters of the impact motions technique were identified. The strongest correlations between the efficiency criterion and various kinematic characteristics of impact motions were identified. Thirdly, the scales for evaluating the kinematic structure of the technique of basic impact motions were developed on the basis of the identified informative parameters. Since the evaluation scales were based on the indicator of the action performance by high qualified athletes, we chose a regression scale. Based on the above algorithm, we have developed scales for evaluating the basic technique of motor actions of athletes, specializing in hand-to-hand combat. Conclusions. Evaluation scales are developed on the basis of the identified informative parameters of the kinematic structure of the technique of the blow and quantitative indicators of these parameters, based on the analysis of the technique of high qualified athletes specializing in hand-to-hand combat.
