An Evidence-Based Model of Power Development in Youth Soccer

Abstract

Power is thought as an essential physical characteristic in soccer, but no systematic and evidence-based model exists to develop this attribute in youth. Both the player's pathway and natural power development were discussed and integrated as conditioning factors to the model, where the player's pathway influenced training integration, block duration, and session length and frequency, while the natural power development dictated training emphasis, mode, intensity and volume. Furthermore, a systematic analysis of training studies that investigated the training of power in youth soccer players was conducted to determine current best practice and limitations. An initial phase concentrating on movement competency and velocity was recommended prior to puberty, before an emphasis on force production during mid-puberty (13–15 y). Once the players enter late puberty (>16 y), maximal strength and power training should be implemented. The number of power training sessions in a block, exercise progression and loading parameters should be viewed as key factors of the training design to enhance movement competency and optimise training adaptations. The implementation of a model will ensure optimal integration of power training and its constituent parts (force and velocity) with clear training emphases throughout the developmental stages of a player.
