Means of teaching young acrobats horizontal emphasis on the elbow on the basis of biomechanical analysis

Relevance. Modern requirements of classification programs in sports acrobatics are due to the need to perform complex coordination of power elements at a young age. Due to the intensive development of the sport, the means and methods of teaching the power elements of young acrobats described at present are not enough. This problem leads to the search for new ways to optimize the process of teaching power technical elements to young athletes, one of which is biomechanical analysis. The purpose of this study was to determine the possibility of using the analysis of the biomechanical characteristics of the basic element of sports acrobatics «horizontal emphasis on the elbow», which is part of the structural group of elements «stops» for the selection of preparatory exercises in the process of its learning. Methods and organization of the study: The study was conducted on the basis of the Federal Sports and Training Center of Gymnastics, an analysis of the biomechanical characteristics of the horizontal emphasis on the elbow and an expert assessment of the quality of the performed element in the control and experimental groups were carried out. All the data obtained were processed using the methods of mathematical statistics. As a result of the study, on the basis of Varignon's theorem, the coordinates of the general center of gravity of the body (OCT) of the athlete were determined, when performing this element, instability in the posterior direction was determined, on the basis of the calculation-analytical scheme (RAS), of the static position of the athlete, the leading muscle groups that ensure the execution of the element and the preservation of balance were determined. Conclusion. As a result of the pedagogical experiment, the proposed preparatory exercises were theoretically substantiated and experimentally tested, statistically significant differences in the control and experimental groups were registered when performing the element. This reflects the effectiveness of the use of biomechanical analysis in the selection of preparatory exercises. Findings. As a result of the study, the biomechanical characteristics of the element are determined, the equilibrium conditions are defined - the moment of gravity in the joints is calculated equal to -12.03 (Nm), preparatory means are substantiated, including exercises for the conjugate development of strength and coordination abilities and their effectiveness has been experimentally proven.
