Goniometric indices of biocouples of the musculoskeletal system at different moments of time during the movement of athletes specializing in practical pistol shooting, the methods of "normal" and "linear" step

Abstract

Annotation. Relevance of the research topic. According to the scientific community, practical shooting has historically developed, first of all, as a competitive activity and specific sports and shooting training for it, as a way to compare, compare and improve human shooting abilities in conditions close to combat. At the same time, practical shooting has been formed as an applied discipline that provides highly effective training for servicemen and law enforcement officers, especially special forces. Perhaps the biggest difference between practical shooting and other types of shooting sports is the variety of exercises that are developed and prepared for each competition new (new location of targets, a new set of obstacles and conditions). The use of standard exercises is limited only to qualification competitions. The purpose of the article is to determine the angular indices of the biocouples of the musculoskeletal system at different moments of time when moving sportsmen who specialize in practical pistol shooting, by the methods of "ordinary" and "linear" step. Material and methods of the research. Participants of the research. In researches participated 10 qualified sportsmen who specialize in practical pistol shooting. Each sportsman realized 5 attempts by ways of moving "usual" and "linear" step. It is important to note that there were no restrictions on the choice of the speed of movement of the athlete, the speed of the series of shots during the attempts. Sportsmen were oriented on that each shot was accurate in a series of shooting, with its performance for a minimum period of time, which actually largely determines the sports result in practical shooting. Research methods. We conducted an experimental study in the laboratory using the optoelectronic system of 3 D registration and analysis of human movements "Qualisys". The results obtained during the study were processed using the methods of mathematical statistics. Results of work. The conducted biomechanical analysis allowed to reveal fundamental differences in the biomechanical structure of the technique of different ways of moving during shooting. Of course, the key indicator that determines the overall effectiveness of the studied action is the result of shooting. However, the overall result is defined as a set of factors of shooting and the time used for it. Further analysis of the situation involves the development of technology for the formation of the technique of moving the shooter while shooting a pistol in motion.
