Objectives: To examine the within- and cross-season neuromuscular fatigue responses in English Premier League U-18 academy football players.
Design: Twenty-five players from the same team completed weekly countermovement jump and isometric adductor and posterior chain strength tests for a full competitive season.
Methods: Global positioning system measures of training and match total, high-metabolic load and sprint distance were recorded daily and converted into exponentially weighted moving average seven- and twenty-eight-day values.
