Finding a predictive value in terms of the contribution of mechanical starting indicators to achieving hammer throwing among young players

Abstract

The research included four sections ,And the first section contained the introduction to the research and its importance. It was discussed, the effectiveness of throwing the hammer and it is one of the competitions with developed technical performance in athletics, which depends on a high level of rapid strength, as it is the key to the technical performance of the hammer and the main key in achieving its level of achievement. This made the interest in understanding the stages of performance for the hammer begin phase, which is of great importance, as this stage affects achievement. As for the research problem, it is to identify biomechanical variables (speed of departure, angle of departure, height of hammer at the moment of departure) that accompany the implementation of the hammer begin and predicting the level of development based on the contribution rate. Changes starting and aim of the research to find a predictive equations of the evolution of the level of achievement in terms of regression of the values of the variables represent. The subject of the research represents the specialized school for players athletics in Baghdad and the use of imaging and mechanical analysis to extract the results of the values
