The data shows a clear consensus: high-performance U12 players should be training 8–12 hours per week across 3–4 sessions, rising to 14–18 hours at U14 and 20–25 hours at U16. France and Italy sit at the upper end of the range, while Norway and Scotland — the most comparable small nations — sit at the lower end. The Canada model recommends 10 hrs/week at U12, which represents a practical benchmark for Ireland.
