Summary

This quasi-experimental study will examine whether a Tactical Critical Thinking Program (TPCT) can improve technical-tactical decision-making in university volleyball players compared with usual training. In many university teams, practice is dominated by repetitive technical drills and coach-centred instruction, with limited opportunities for players to analyse the game, discuss options with teammates, or reflect critically on their decisions. The study compares two groups of adult male volleyball players from a university-level programme in Colombia. The intervention group completed a 4-week Tactical Critical Thinking Program integrated into regular volleyball practice, while the comparison group continued with their usual training routines, without structured reflection or guided questioning. The TPCT uses representative game-based tasks, short planned pauses for group discussion, and questions that prompt players to identify tactical problems, generate alternative solutions, justify their choices, and adjust strategies collectively. All participants assessed before and after the 4-week period. Assessments included validated technical skill tests for serve, reception and spike, and standardised small-sided games (4 vs 4) recorded on video. Trained observers coded each action to calculate decision-making indices for the three key skills, expressing the proportion of tactically appropriate decisions during play. The primary aim was to determine whether adding structured tactical reflection and critical thinking activities to volleyball practice produces greater improvements in decision-making than usual training alone. A secondary aim was to explore whether the TPCT also enhances technical execution. Findings are expected to inform coaches and physical education professionals about how to design cognitively enriched, game-representative training for university team sports.

Detailed description

This interventional study evaluates the effect of a Tactical Critical Thinking Program (PTPC, by its Spanish acronym) on technical-tactical decision-making in university volleyball. The study uses a quasi-experimental, non-randomized, parallel-group design with intentional allocation. One group receives regular volleyball training enriched with the PTPC, and a comparison group continues with usual practice routines without structured reflective spaces. The setting is a university men's volleyball programme in Cartagena, Colombia. Eligible participants are adult male players who belong to the university team, have regular training experience, are medically cleared for full participation and can attend the planned training and assessment sessions. Exclusion criteria include any current injury or medical restriction for sport participation and an inability to comply with the intervention schedule. The PTPC integrates critical thinking and collaborative reflection into representative volleyball practice. Across approximately 12 sessions, embedded within normal team training, each session follows a stable pedagogical sequence. An initial brief activation phase clarifies the tactical focus of the day (for example, organisation of reception, serve-receive-attack connections or spike decision-making) and invites players to identify recurrent problems and shared objectives. The central phase consists of game-based drills and small-sided games that manipulate numerical relations, court spaces and rules to expose players to tactically demanding situations involving serve, reception, spike and defensive actions. Within this central phase, the coach introduces short, preplanned pauses in which players analyse recent sequences and discuss what is working, what is limiting performance, which technical resources they use or lack, and which tactical or positional adjustments they propose. A final phase of more open play under full rules emphasises the application and refinement of the agreed tactical adjustments and promotes metacognitive reflection on why certain options are chosen and how they relate to collective strategy. The comparison group follows the usual training programme designed by the coaching staff. This programme includes warm-up, physical preparation, technical drills and team game play, but it does not include the protocolised reflective pauses or the guided questioning structure that characterises the PTPC. Training volume, frequency and general intensity remain as comparable as possible between groups so that the main planned difference is the presence or absence of the structured critical-thinking component. Outcomes focus on technical-tactical performance in serve, reception and spike. Technical execution is assessed through a standardised battery of volleyball skill tests that quantify accuracy and consistency for each action using target zones and scoring criteria based on established methodological references. Tactical decision-making is assessed during standardised small-sided games (for example, 4 vs 4) on a regulation court under official rules. Games are video recorded, and trained observers code each serve, reception and spike as tactically appropriate or inappropriate according to predefined criteria (such as serving to vulnerable zones, directing reception to an optimal setting area, or attacking into uncovered spaces). For each player and each skill, a decision-making index represents the proportion of appropriate actions out of the total number of observed actions. Assessments take place in the week immediately before the intervention period and in the week after its completion. Data collection also includes basic sociodemographic and anthropometric information (for example, age, training experience, body mass, height and body mass index) in order to characterise the sample and, if necessary, use these variables as covariates. Observers receive training in systematic notation of volleyball actions, and inter-observer agreement is checked prior to formal coding to ensure acceptable reliability. Data management relies on anonymised participant codes and secure storage of datasets and video material. Statistical analysis describes the sample with means, standard deviations, medians and interquartile ranges as appropriate. Pre-post changes in decision-making indices and technical scores are analysed within each group, and differences in change between the PTPC and comparison groups are examined with standard parametric or non-parametric tests according to distribution, complemented by effect sizes and 95% confidence intervals. The level of significance is set at 0.05, and interpretation acknowledges the quasi-experimental, non-randomized nature of the design. The study aims to provide evidence on whether embedding a structured critical-thinking programme into routine volleyball practice optimises decision-making and technical performance, and whether this model offers a transferable framework for other team sports and educational contexts.

Interventions

Type	Name	Description
OTHER	Tactical Critical Thinking Program plus usual volleyball training	Behavioral intervention integrated into regular university men's volleyball practice. The program adds structured reflective pauses and guided questioning to usual training content (serve, reception, spike and team play). Sessions use game-based drills and small-sided games under modified constraints to elicit tactically demanding situations. After short sequences of play, the coach leads brief discussions in which players identify tactical problems, generate and justify alternatives and agree collective adjustments. A final phase of open play emphasises applying these decisions while promoting metacognitive reflection. Training frequency, duration and physical workload remain comparable to the control arm; the distinctive element is the protocolised critical-thinking and collaborative-reflection component.
OTHER	Usual volleyball training	Behavioral condition consisting of the team's standard university men's volleyball training program with no added reflective component. Sessions include warm-up, general physical preparation, technical drills for serve, reception, spike and defence, positional work and team play under normal coaching practice. Coaches do not apply the structured reflective pauses or guided questioning protocol used in the experimental arm. Training schedule, session duration and general intensity are maintained as similar as possible to the intervention arm so that the principal difference between arms is the absence of the Tactical Critical Thinking Program.
