The aim of the study was to do a systematic review about the effects of strength programs used in pre-adolescent and adolescent male football players. A total of twenty-five articles, in Spanish or English, were analyzed by searching PubMed, ISI Web of Knowledge and SportDiscus. Plyometric training, followed by strength-resistance training and isoinertial training, in that order, were found to be commonly used for strength training in pre-adolescent and adolescent footballers. However, depending on the maturation state, and the player’s motor experience, they seem to generate different adaptations in these, and therefore, require an individualization of the training load depending on their physical and technical level.
