         Shooting in handball is one of the most important basic skills, as hitting the goal is the final result of the team's effort and the decisive factor in determining the result of the match as the boundary between victory and defeat, and shooting from the corner area is one of the most difficult types of shooting in handball, as it requires high skill, due to the narrowness of the shooting angle and the proximity of the scoring area to the field line, as well as the presence of the opposing player and the goalkeeper of the opposing team, which makes accuracy the decisive factor in the success of the shooting, and it is certain that The success of the player in performing the basic offensive skills, including the accuracy of shooting, does not depend only on the development of physical and skill abilities and the design and construction of tests, but also on taking into account the distinctive mechanical aspects of performance, believing that these exercises prepared according to the variable of the work performed, the variable of kinetic energy, and the latent moment of support and push will contribute to addressing weaknesses and trying to improve and develop performance. The researchers noticed through their interest and follow-up of the game of handball as well as their specialization in biomechanics that there is a weakness in the accuracy of shooting from the corner area and the lack of exploitation of the transfer of energy through the correct motor path of performance as well as the lack of interest in this center despite the fact that it is considered one of the very important centers in the game of handball and that the goal of the research is to prepare special exercises according to the work done using the platform to measure strength To develop the index of shooting accuracy from the corner area and the energy transfer index of the corner players of the advanced clubs of Diyala and Karkh in handball. As for the research impose, there are statistically significant differences between the results of the pre- and post-tests between the biomechanical variable of the completed work and the energy transfer index and the accuracy of shooting among the players of the Zawiya area of the Diyala and Karkh clubs who are advanced in handball.
