الملخص

The progress in the level of performance of sports games was the result of the use of scientific and modern methods to develop the situation of the individual athlete and make him reach the highest and best level at the type of practicing activity.  Football is one of the most collective games that received a great deal of importance, research and privacy, so the follower notes the great progress achieved at the level of physical performance, technical and planning and high skill. As a result, it has become difficult to achieve goals in an easy way. The win in football is achieved by scoring goals that have become very difficult due to the lack of opportunities on the one hand and the circumstances of the game on the other hand, and corner kicks are an important factor in determining the win in favor of the team in football.

Corner kicks are a live and repeated model in matches, in cases approved by the law, such as the exit of the ball by the opposing team player, causing a corner kick that may cause a goal. Therefore, the researchers designed exercises to develop the accuracy of the corner kicks according to the biomechanical variables l in order to reach the best exploitation of corner kicks and achieve goals from them or contribute to it. The research aims to

1.Identify the most important biomechanical variables affecting the performance of corner kicks.

1. Prepare special exercises according to the biomechanical variables to improve the performance and accuracy of the corner kicks
2. Identify the impact of special exercises on developing of the performance and accuracy of corner kicks.
