The football game has witnessed a great development in terms of the speed of play, possession and pressure on the ball carrier. Those involved in the game have to keep pace with this development through the use of integrated training programs that contain basic and advanced exercises that take care of most details of the game in addition to paying attention to the physical and movement that the player needs during the performance, such as Strength, speed, endurance, flexibility, ability,

... , coordination. and what is associated with it, especially during defensive or offensive football performance, which contributes to controlling the course of the game. The importance of the research is that it is a research attempt that is concerned with consolidating the idea of a stress playing style in the reality of Iraqi clubs and teams training through this defensive method to achieve the desired goal, as well as experimenting with the use of defensive exercises characterized by rapid application and high accuracy together, and to know the extent of the impact of exercises in the style of compressive play on the development of some biomechanical capabilities of young football players in a step aimed at strengthening the sports field with practical experiments and service to researchers in the sports field. The research aims to identify the impact of exercises with a stress playing style on the development of some biomechanical capabilities of young football players. The researchers identified the research community, who are the (23) players of the Al-shuohda football Club, and the research sample was chosen by a random method (lottery) of (10) players, appropriate statistical means were used to find differences in the pre and post-tests. The researchers came out with the following conclusions: Compressive play style exercises developed some biomechanical capabilities (movement speed, agility and compatibility) for the experimental group under discussion, compressive play exercises simulated the player for the same conditions of the match.
