Abstract

Background: This study examines the influence of Peak Height Velocity (PHV) on motor abilities and anthropometric characteristics of young male football players aged 12–16. The research aimed to determine whether PHV significantly affects motor performance beyond the chronological age, providing insights for talent identification and training optimization. Materials and methods: A total of 248 male football players from four professional academies were assessed and categorized into three maturation groups: Pre-PHV (n = 95, 38.3%), Mid-PHV (n = 98, 39.5%), and Post-PHV (n = 55, 22.2%) Anthropometric measurements included height, body mass, BMI, and leg length, while motor tests evaluated sprint speed (5m, 30m), lower limb power (CMJ, SJ), and anaerobic endurance (RAST test). The study protocol was preregistered in the Open Science Framework (DOI: 10.17605/OSF.IO/PCEB4). Results: The findings revealed significant differences in height (F = 183.18, p < 0.001), weight (F = 263.39, p < 0.001), and BMI (F = 274.70, p < 0.001) across PHV groups, confirming that biological age strongly influences physical development. Sprint performance showed substantial improvements, with Post-PHV players achieving faster times in 5m sprints (Pre-PHV: 1.08±0.08s vs. Post-PHV: 0.97±0.05s, η² = 0.342, p < 0.001) and 30m sprints (Pre-PHV: 4.82±0.37s vs. Post-PHV: 4.39±0.29s, η² = 0.311, p < 0.001). Explosive power, measured through jump height and peak power output, demonstrated the strongest association with biological maturity (CMJ: η² = 0.349; SJ: η² = 0.365; Pmax_abs: η² = 0.328, all p < 0.001), with the greatest improvements observed in the Mid- and Post-PHV phases. Conclusions: These results highlight the necessity of considering biological age in youth football selection and training. While PHV plays a crucial role in motor development, its effects are not uniform across all physical attributes.
