Abstract

Statement of the problem. Modern method of execution for giant Felge backward on the bar is one of the basic elements of modern artistic gymnastics, and is widely used by gymnasts. However, if the structural differences between modern and classical methods of execution for this element are obvious, in quantitative terms they are not developed enough. To solve this problem, it is necessary to study the kinematic structure of the modern giant Felge backward using modern instrumental methods and compare it with the classical one. The above said proves the relevance of this study. The purpose of this article is to explore the kinematic structure of the modern method of execution for of giant Felge backward on the bar in the performance of a highly skilled gymnast. With the use of video and modern software the study is meant to determine the movement, velocity and acceleration of the reference points of the four-link model of the athlete,s body, as well as joint movement, angular velocity and angular acceleration. Reference points and angles are aimed to be identified. The research methodology consists of a set of instrumental research methods, in particular, the use of video and software “MaxTrack” for processing video materials, computer technology, as well as theoretical analysis and synthesis of special literature data by international and Russian scientists and program documents. Research results. The kinematic structure is studied of the modern method of execution for giant Felge backward on the crossbar performed by a highly qualified gymnast. Conclusions. Using modern instrumental methods, movements, velocities and accelerations of reference points of the four-link model of the athlete»s body, articular movements, angular velocities and accelerations are determined. Plots of control points and angles are constructed. It is proved that a modern method provides greater maximum velocity at the lower point of the swing and creates more favorable velocity and structural conditions for the implementation of subsequent complex flights and jumps from the crossbar.
