Biomechanical Characteristics of Sports Technique Key Elements in Dismount Off Beam

Junior Gymnasts 12 to 14 Years Old

Abstract

The main goal of this work is the video computerized analysis of the characteristic sports technique key elements of the rounded-off dismount off beam in the basic specialization stage in women’s artistic gymnastics. The biomechanical analysis was performed by means of a specialized program called Physics ToolKit Version 6.0, focusing on the key elements of sports technique: start position of the body, multiplication of body position and final position of the body. The findings of the study point out the comparative biomechanical analysis of the key elements of rounded-off dismount on beam performed by junior gymnasts. The biomechanical characteristics of the video analysis of a rounded-off dismount on beam highlight the duration of key elements, the trajectories of body segments, the maximum height of general centre of gravity and the dismount length, also the influence of the biomechanical indicators on the correct execution of the dismount. The characteristics of the key elements of the analyzed rounded-off dismounts off beam highlight differences of gymnasts’ anthropometric measurements; the height and length of the dismount depend on the values of the biomechanical indicators specific to the characteristics of the movement of translation with rotation. The biomechanical analysis of rounded –off beam dismount highlighted the characteristics of the key elements and the influence of the biomechanical indicators on the dismount technical execution, fact that confirms the hypotheses proposed and the performances achieved in competition.
