Brief Summary

The aim of this study was to examine the effects of the Tactical Programme for Critical Thinking (TPCT) on tactical performance and critical thinking (CT) skills in elite male underwater rugby (UWR) players. Twenty-four players (age: 29.38 ± 7.11 years; experience: 10.86 ± 4.82 years) were divided into two groups: one following a structured TPCT intervention and another maintaining their standard training routine (STR). The intervention consisted of 20 sessions (two per week) focused on tactical principles in UWR. Tactical performance was assessed using the RUSTAC test, while critical thinking skills were evaluated with the Critical Thinking Measurement Index.

Outcome Measures

Primary Outcomes (2)

  • Tactical Efficiency Index

    Description: Data analysis in this study utilised the Tactical Underwater Rugby Test (RUSTAC) instrument, which has been validated for use in underwater rugby (Content Validity Coefficient: 0.92). RUSTAC provides a comprehensive evaluation of tactical actions in gameplay, focusing on key principles of offensive and defensive phases. The instrument was used to assess five key variables during gameplay: penetration, offensive coverage, space, defensive coverage, and recovery. Additionally, Tactical Performance Indices (TPI) were calculated for both offensive and defensive zones, and general gameplay efficiency. The Tactical Performance Indices are scored on a scale from 0 to 1, where 1 indicates the highest efficiency and 0 the lowest efficiency. Therefore, higher scores represent better tactical performance.

    Week one and Ten

  • Critical Thinking

    Critical thinking was assessed using the IMPC OSBA VS2 (Critical Thinking Measurement Index VS2), developed in Medellín, Colombia. This instrument evaluates critical thinking via evaluation, argumentation, analysis, inference, and interpretation. Adapted for participants from Medellín, it ensures cultural relevance. Reliability (Cronbach's alpha 0.659) and validity (KMO 0.52, Bartlett's p\<0.001) were confirmed. It explains 69.48% of variance. Scored 0-100, 100 is highest critical thinking; higher scores indicate better skills.

Study Arms (2)

Standard training routine (STR) group

ACTIVE COMPARATOR

Both TPCT and STR groups will follow identical underwater rugby training sessions. Structure: Warm-up (15%): Land-based mobility (5 min) + in-water rondos (10 min). Small-Sided Games (30%): Tactical principles via modified scenarios. Full-Team Games (45%): 6v6, 5-min games with 3-min recovery. Cool-down (10%). Training includes 20 sessions: 8 defensive (Containment, Recovery) and 12 offensive (Penetration, Offensive Coverage, Space). SSGs focus on tactical principles: Containment (4v4, restricted defensive movement) → Defensive positioning, communication. Recovery (5v6, interception-based) → Quick transitions, passing accuracy. Penetration (4v2, lane-based) → Offensive coordination, defensive pressure. Offensive Coverage (6v6, restricted movement) → Off-the-ball play, passing options. Space (3v4, defenders in pairs) → Forward movement, spatial awareness.

Other: STR Group

TPCT Group

EXPERIMENTAL

Both TPCT and STR groups followed identical underwater rugby training: Warm-up (15%), SSGs (30%), Full-Team Games (45%), Cool-down (10%). Training included 20 sessions: 8 defensive (Containment, Recovery) and 12 offensive (Penetration, Offensive Coverage, Space). SSGs focused on tactical principles: Containment (4v4) → Defensive positioning, communication. Recovery (5v6) → Quick transitions, passing accuracy. Penetration (4v2) → Offensive coordination, defensive pressure. Offensive Coverage (6v6) → Off-the-ball play, passing options. Space (3v4) → Forward movement, spatial awareness. The TPCT group engaged in 10-min reflective discussions post-warm-up, SSGs, and games. Prompts included: "What key moments defined the activity?" "How effective were our decisions?" "How well did we contain attackers?" "What hindered or helped recovery?" "How could we improve movement and space usage?" Players progressively led discussions, enhancing tactical awareness.

Randomization was performed using block random number generation \[16\], with block sizes of 4-6 and stratification based on experience (low: \<2 years, medium: 2-4 years, high: \>4 years). An external individual, independent of the research team, carried out the allocation to ensure unbiased group assignments. To minimize bias, participants were unaware of the study objectives or their group assignments.
