This study compared the effects of velocity-based strength training and traditional strength training on physical performance and muscle adaptations in youth soccer players. Twenty-four male youth soccer players were randomly assigned to one of three training groups: velocity-based training with 10% velocity loss, velocity-based training with 20% velocity loss, or traditional resistance training performed to failure. All groups trained twice per week for six weeks using the same relative load.
Before and after the training period, participants completed assessments of sprint performance, jump performance, change of direction speed, muscle strength, and muscle thickness. The purpose of this study was to determine whether velocity-based training could provide similar or superior improvements in performance and muscle development compared with traditional training while using a lower total training volume.
