Longitudinal study investigates seasonal changes in performance characteristics of competitive youth soccer players, indicating biological impacts.

Key Points

The research aims to investigate how physical performance and anthropometric characteristics develop over a competitive soccer season in youth players.
Longitudinal repeated-measures design conducted over one competitive season.
Anthropometric characteristics and performance metrics assessed at three time points: preparation, mid-season, and end-season.
Performance measures included jump tests, sprint times, VO2max estimation, and repeated-sprint sets.
Body mass increased from 64.1 ± 6.7 kg to 66.7 ± 6.8 kg, height from 1.69 ± 0.07 m to 1.72 ± 0.07 m, and body fat decreased from 11.3 ± 2.0% to 9.4 ± 1.8% (F ≥ 12.0, p < 0.001).
Significant improvements were observed in squat jump, 30 m sprint, and VO2max, with set-dependent adaptations in repeated-sprint performance (F ≥ 3.28, p ≤ 0.046).
Peak height velocity significantly influenced body mass and height, but not body fat percentage.
