Abstract

Introduction: The UEFA Youth League (UYL) is the highest level of European academy football; yet little is known about its physical demands or how they differ from domestic competition. We compared UYL (U-19) and English Premier League (EPL) academy U-18 and U-21 match running demands at team and positional levels. Methods: Match running data were collected across two seasons from a single EPL Category 1 academy. Thirty-six matches (six per team per season) provided 305 full-match observations for 45 players. GPS and MEMS devices quantified total distance (TD), high-speed running (HSR), sprint distance, high-metabolic-load distance (HMLd), explosive distance (ED), and counts of high-intensity accelerations and decelerations. Linear mixed-effects models with Tukey-adjusted contrasts and Cohen's d effect sizes (ES) were applied. Results: TD was greater in the U-18 s than U-19 s (p < 0.01;ES = small) but similar between the U-18 s and U-21 s (p > 0.05;ES = trivial). However, high-intensity demands largely increased with age: U-19 and U-21 players performed more decelerations than U-18 s (p < 0.01;ES = small), and U-21 s performed more accelerations than U-18 (p < 0.05;ES = small). Wide midfielders (WM) had the greatest HSR, sprint, HMLd, acceleration, and deceleration demands (p < 0.001;ES = small); central midfielders (CM) covered the greatest TD (p < 0.001;ES = small) and had high ED and HMLd (p < 0.05;ES = small); while wide defenders (WD) and forwards had high acceleration and deceleration demands (p < 0.05;ES = small). Conclusion: While TD was similar across age groups, high-speed and high-intensity demands increased with age, especially in wide and central roles. Transitioning from U-18 to U-19 and U-21 competition imposes meaningful increases to match speed and intensity, requiring targeted physical preparation.
