Biomechanical Analysis of Sports Technique Key Elements in Back Double Somersault Dismount off Uneven Bars-Junior Gymnasts 12 to 14 Years Old

Abstract

The main goal of this work is the computerized video analysis of the characteristic key technical elements of the double somersault dismount off uneven bars in the basic specialization stage in women's artistic gymnastics. The study was conducted during the Masters National Championships, Oneşti, 16-18 November, 2012. The subjects of the research were 7 female gymnasts, 12 to 14 years old, members of the Junior Olympic Team in Deva and finalists on this apparatus. The biomechanical analysis was performed by means of a specialized program called Physics ToolKit Version 6.0, focusing on the key elements of the technique (as per Boloban, V., 1990): starting position (SP), multiplication of body position (MP) and final position (FP) of the body. The biomechanical analysis of double somersault dismount off uneven bars highlighted the characteristics of the key elements and the influence of the biomechanical indicators on the technical execution of the dismount. The analysis of the execution of the dismount in comparison with the requirements of the technical regulations of the International Code of Points for uneven bars will generate new methodological guidelines meant to improve and correct executions, thus confirming the hypotheses proposed and the performances achieved in competition.
