A three-dimensional analytical study of some kinematic variables of the throwing phase for the effectiveness of weight pushing and its relationship to the achievement

Abstract

The importance of the research came through the analysis of kinematic variables by three-dimensional analysis by  measuring the real distance and thus finding the real speed because the time measured in the two dimensions represents the time of all movement and not the time of movement in the two dimensions and reaching hypothetical values for angles that can only be estimated using the scene from above or from below, as well as the use of scene rotation as a means of feedback because this allows the discovery of all the space of movement, and the study aimed to analyze some kinematic variables in three-dimensional form of the throwing phase for the effectiveness of pushing the weight as well as identifying the relationship between kinematic variables The researcher used the descriptive approach to suit the nature of the problem to be solved. The research community was identified of three (3) players from Diyala clubs registered with the Athletics Sub-Union. The research sample was chosen in a deliberate manner. The researcher adopted the number of views as each player was given six attempts, so the number of views for each variable reached (18) views. The field research procedures included conducting video imaging and kinematic analysis to extract the kinematic variables in a three-dimensional way through The three axes (x , y, z) and the  outcome (the time of the final throwing phase (the time of doubles anchoring), the displacement outcome of the body parts, the velocity and acceleration achieved for the body parts),  using the (Apas) program, in light of the results obtained by the researcher, the researcher concluded that there is a significant correlation between the displacement outcome, velocity and acceleration of the body parts towards the three axes (x , y, z). The results also showed a significant correlation between displacement, velocity and acceleration achieved for the body parts and achievement. The researcher recommends that emphasis be placed on conducting kinetic analysis to identify defects and weaknesses in kinetic performance and conducting periodic tests and kinetic analysis to monitor the level of development in mechanical and technical aspects.
