TPCT Underwater Rugby Women

This randomized controlled trial evaluates whether adding a short, structured team-reflection protocol (Tactical Programme for Critical Thinking, TPCT) to regular elite women's underwater rugby training improves tactical efficiency. Both groups complete the same training content and time; the TPCT group uses brief guided discussion during recovery intervals, while the control group uses the same time for passive recovery. Tactical efficiency is assessed using video-recorded 3v3 scrimmages coded with the RUSTAC checklist at baseline and after 6 weeks.

A parallel, two-arm randomized controlled trial will be conducted in an elite women's underwater rugby squad. Players will be allocated 1:1 to TPCT or an active control condition using a computer-generated random sequence. The intervention consists of 18 sessions over 6 weeks (3/week), 2 hours per session, delivered in an outdoor 4 m pool and a marked 10 m × 8 m underwater area. Sessions include a short coach introduction (\~15 min), constrained small-sided games designed to elicit target tactical principles, and ≥60 min free-play (≥50% of session) to preserve representativeness and transfer. The TPCT condition embeds \~3 min structured reflection between small-sided bouts using a fixed 5-question protocol aligned to critical thinking operations; the control condition uses equivalent between-bout time for passive recovery/hydration.
