Biomechanical structure of double forward somersault dismount in tuck position on parallel bars swinging back from the stop and methods of its development

Statement of the problem. In exercises on parallel bars, the double somersault forward dismount in a tuck position with a backward swing from the stop is the culminating final chord that completes the logical, aesthetically solid construction created by the gymnast's motor means. Currently, this is one of the most difficult modern jumps, often performed by highly qualified gymnasts at major competitions. Landing on the board after it at the end of the combination significantly increases the gymnast's chances of getting a high score. However, the phasal biomechanical structure of its execution technique has not been studied enough. This is due to the use of conventional video cameras with a low shooting speed (25 fps). The problem is to develop a method for mastering the technique of performing the double somersault forward dismount in a tuck position on parallel bars swinging backward from the stop using a highspeed Phantom camcorder at a speed of 500 fps. The purpose of the article is to identify the phasal biomechanical structure of the technique of performing a double somersault forward dismount in a tuck position on parallel bars with a backward swing from the stop and to develop a method of its mastering. The research methodology consists of a complex of instrumental methods, in particular using high-speed video camera Phantom at a speed of 500 fps, software “Tema MaxTrack” to process video materials, computer technology, and theoretical analysis of literature of international and Russian scientists and policy documents, teacher observations, structural-phase and pedagogical and biomechanical analysis. Research results. The phasal biomechanical structure of the technique of performing a gymnastic element - a double somersault forward dismount in a tuck position on parallel bars - is revealed. An effective method of teaching this element has been developed and justified. Conclusion. Using modern instrumental methods, the biomechanical phase structure of the technique of performing a double somersault forward dismount in a tuck position on parallel bars was studied on the basis of the methodology of the interdisciplinary direction of pedagogical biomechanics. The biomechanical characteristics of the phase microstructure were determined using data from high-speed video (500 fps) and a pedagogical- biomechanical structural-phase model was constructed.
