Особливості кутових характеристик техніки прямого удару правою рукою з лівосторонньої стійки у висококваліфікованих спортсменів, які спеціалізуються в рукопашному бою

Abstract

Topicality. Among the most urgent and fundamental areas of hand-to-hand combat technique research, one can single out kinematic analysis within certain phases, as well as within the framework of a complete exercise. The Research Purpose is to determine of the angular characteristics of the right-hand strike technique from the left-sided stance of highly qualified athletes specializing in hand-to-hand combat. 12 highly qualified athletes took part in the research. The following Research Methods as theoretical analysis, pedagogical and mathematical methods have been used in the study. The Research Results. Since there is no swing phase of straight kick, the preparation phase of kicking immediately precedes the impact action phase. During the preparation phase, athletes slightly bend their left leg, the left knee joint angle decreases by 3,8° (from 123,1° to 119,3°), and in the left hip joint by 4,2° (from 134,4° to 130,2°). Since there is no early swing phase of straight kick, the preparation kick phase immediately precedes the percussive impact phase. During the preparation phase, athletes slightly bend their left leg, the left knee joint angle decreases by 3,8° (from 123,1° to 119,3°), and in the left hip joint angle – by 4,2° (from 134,4° to 130,2°). The right leg remains practically immobile: the right knee joint angle at the beginning of the phase is 137,1°, and at the end of the phase it is 136,5°, that is, it decreases by only 0,6°; the right hip joint angle at the beginning of the phase is 145,9°, and at the end of the phase is 147,8°, increasing by 1,9°. The angular indicators of the upper limbs movements during the preparation phase for the impact have the following changes: the left shoulder joint angle increases by 6° (from 44.6° to 50,6°), the left elbow joint angle decreases by 6° (from 57,3° to 51,3°), the right shoulder joint angle increases by 4,5° (from 30,4° to 34,9°), and in the right elbow joint angle increases by 19,8° (from 51,8° to 71,6°). Findings. The straight right hand kick from the left stance is one of the most widely used and effective kicks in hand-to-hand combat. Also, due this kick, the greatest damage is inflicted on the opponent.
