ANALYSIS OF THE KINEMATIC STRUCTURE OF THE RIGHT SIDE BLOW TECHNIQUE FROM THE FRONTAL STANCE IN HIGHLY QUALIFIED ATHLETES SPECIALIZING IN HAND-TO-HAND COMBAT

Abstract

The objective is to analyze the kinematic structure of the side blow technique with the right hand from the front stance of highly qualified athletes who specialize in hand-to-hand combat. Methods. Theoretical – to determine the relevance of the problem of forming the technique of motor actions in hand-to-hand combat; empirical: pedagogical observation as a method of empirical level of research – to familiarize with the process of organizing educational and training classes; registration of the kinematic characteristics of the technique of the side blow with the right hand from the front stance was carried out using the marker system of registration and analysis of Qualisis movements, which allowed to record the data in three-dimensional space. The shooting frequency was 100 frames per second. The error in determining the spatial indicators was 1 millimeter per 1 meter of cubic space, the error in the time indicators was 0.01 seconds, which ensures high accuracy of registration of the kinematic characteristics of the sportsmen’s movement actions. Methods of mathematical statistics. We’ve registered the technique of performing the studied motor action in 12 highly qualified athletes. Results. A side blow with the right hand from the front stance attempt; 3rd phase – blow movement; 4th phase – contact; 5th phase – return to the starting position. In the process of the research, we determined the duration of the phases of the side blow with the right hand from the frontal stance of highly qualified athletes who specialize in hand-to-hand combat. The first four phases of the movement are the most important, since it is the athlete’s motor actions in these phases that directly affect the effectiveness of the blow. The total duration of these four phases is 0.44 seconds, or 39.6% of the total duration of the impact. While the phase of returning to the starting position lasts 0.62 seconds, i.e. 60.4% of the total duration of the blow as a whole. Conclusions. In this way, it can be proven that highly qualified athletes who specialize in hand-to-hand combat effectively perform striking actions with a right-handed blow from the frontal stance, therefore, the indicators of the kinematic structure of their movement technique can be used as reference model characteristics for athletes of lower qualifications.
