The percentage of contribution of some kinematic variables of the arms in developing the performance level of the handball forward shooting skill

Abstract

Abstract

The research included four chapters. The first chapter contained the introduction to the research and its importance. It dealt with the game of handball, which is a competition with complex technical performance and shooting skill, which depends on a high level of strength and speed. As it is considered the primary key in achieving the skill goal, this is the main key in achieving victory, which made the interest in understanding the performance variables of the arms to be of great importance because these arms affect the accuracy of shooting. The problem of the research is to identify the biomechanical variables that accompany the implementation of the skill of shooting forward from the right side and prediction. The level of development based on the contribution rate of the kinematic variables of the shoulders and elbows. The aim of the research is to find predictive equations for the level of development in terms of the regression values of the variables. The research sample represents the players of the Specialized School of Handball. Imaging and mechanical analysis were used to extract the results. The researcher concluded that the variable (angular acceleration of the left shoulder) contributed with the highest contribution rate. Aim accurately by jumping to the right.
