Аналіз Кінематичної Структури Прямого Удару Правою Рукою З Лівобічної Стійки Ветеранів З Різним Досвідом Занять Адаптивним Рукопашним Боєм

Introduction. To analyze the kinematic characteristics of the right direct hand strike from the left side stance of veterans with lower limb amputations who have different experience in adaptive hand-to-hand combat. Materials and Methods. A video computer analysis of the kinematic structure of the right direct hand strike from the left side stance was performed using the Qualisis motion analysis system. Two veterans with different experience in adaptive hand-to-hand combat participated in the study: serviceman P. with a left leg amputation at the level of the upper third of the tibia, who successfully completed the prosthetics stage and has long-term experience in hand-to-hand combat, and veteran M. with a right leg amputation at the level of the upper third of the tibia, who also successfully completed the prosthetics stage with 60 days of experience in adaptive hand-to-hand combat. Results. The total duration of the reception, the veteran with experience, the total duration of the blow is 1.15 s, and the veteran without experience of training is 1.86 s, The speed of the impact biolink reaches its maximum value at the moment of the end of the impact movement phase and the beginning of the contact phase. It can be used as a criterion for the effectiveness of the impact action. The value of the maximum speed of the impact biolink when performing a right direct blow with the hand from a left-sided stance for serviceman P. is 7.75 m·s-1 at S=0.51 m·s-1, while for veteran M. this indicator is 2.66 m·s-1 at S=0.34 m·s-1. The coordination of the legs when performing a direct blow with the hand in the serviceman P. is optimal: the back (right) leg is extended by a total of 14 °, which allows to increase the force of the blow by including its muscles in the work, and the front (left) leg plays the role of a fixed support around the axis of which the pelvis and torso turn, which also allows to include their muscles in the strike. While in veteran M. the value of the angles in the joints of the striking arm during the striking movement phase increases by 35 ° and 85 °, respectively, which indicates that the blow is performed mainly due to the extension of the arm, and the minimal inclusion of the muscles of the torso and legs in the blow. Conclusions. A biomechanical analysis of the kinematic structure of the technique of a right direct blow with the hand from a left-sided stance in veterans with and without experience in adaptive hand-to-hand combat was conducted. The indicators of the kinematic structure of the motor actions of both veterans were determined and evaluated, according to the results of the evaluation, the right direct blow technique of the veteran with experience of training is more effective, as evidenced by the quantitative biomechanical characteristics of the movement technique. The indicators of the right direct blow technique of veterans with experience and without experience of training in adaptive hand-to-hand combat can be used in the process of physical education and sports rehabilitation of veterans as objective quantitative data for expert assessment.
