This pilot randomized controlled trial aims to evaluate the preliminary effects and feasibility of a four-week Reverse Nordic Exercise program on countermovement jump performance in youth soccer players during the competitive season. Participants are randomly allocated to either a Reverse Nordic Exercise group, which performs a progressive eccentric quadriceps training program in addition to regular soccer training, or a control group that continues usual training. Countermovement jump performance is assessed before and after the intervention to estimate potential treatment effects and inform the design of a future fully powered randomized controlled trial.
