Résumé:
The aim of this study is to determine the effect of morphological composition on the functional efficiency of football players according to the centers of play by determining the standard levels of morphological and functional characteristics to determine the real level of the players and the detection of strengths and weaknesses. Therefore, we conducted a descriptive study on a random sample, We have found that most of the morphological and functional characteristics of the research sample are at the intermediate and generally acceptable level. The good level of morphological formation results in high functional efficiency, and therefore, Using these levels is recommended to address weaknesses and a review of the training load as these levels allow players to choose the best form and efficiency.
