Résumé:
The delimiters are the most important tools, widely used in training and tests soccer, because they embodies the dimensions of the surface and the role of defender in major of the exercises for Soccer. The literature review 90% of soccer books use the smallest delimiters (plate) and 100% of our young soccer Algerians coaches (under 15 year) composed their sessions. From that, the objective of our study focuses to the conflict that the dribbling test measures the speed and agility for most authors where (Philippe Leroux, 2006) confirms that this test measures the speed not the agility. Our hypothesis confirms that Dimensional of smallest delimiters affected the qualities coordinators during the change of direction Due to absence of obstruction of the upper body player, which requires more qualities coordinative as Speed, Balance and the Agility in particular when he front real defender. Our experience is based on a practical protocol of zerf Mohammed (set in figure 2) from his study entitled “The impact Dimensional of delimiters on testing and training dribbling in young soccer (under 15 year)”. Were we have trained our sample for two weeks based in the different kinds of delimiters (figure 1) and we have tested and retested them in test T for agility, test 30M for speed and 20M slalom with the ball(dribbling). Based on results and the signification of the statistical practiced our finding confirmed: •The mannequin is the most delimiter appropriate to develop Speed, Balance, Agility and dribbling in soccer (under 15 year).
