Abstract

Background: Rugby has not grown extensively in Africa compared to other continents, necessitating talent identification (TID) programs to recruit junior talent. However, it is unclear which physical characteristics and rugby-specific game skills to base the objective recruitment of potentially talented young players.

Objectives: This study profiled the physical fitness characteristics and rugby-specific game skills of schoolboy rugby players by playing standards to identify variables differentiating elite from sub-elite players from Under 16 (U16) to U19 age categories. The study further compared Zimbabwean cohort data with similar data from international/regional countries.

Methods: A cross-sectional design was utilised with 158 Zimbabwean schoolboy players playing competitive (elite) and noncompetitive (sub-elite) rugby. The participants were measured for anthropometrics, speed, agility, upper-and-lower-muscular strength/power, muscle flexibility, prolonged high-intensity intermittent running ability, repeated high-intensity exercise performance ability, tackling, passing, and catching abilities.

Results: For U16s, Vertical Jump (VJ), 2kg Medicine Ball Chest Throw (2kg MBCT), Wall-Sit-Leg Strength (WSLS), Yo-Yo Intermittent Recovery Level 1 (Yo-Yo IRL1), Tackling and Catching Ability tests discriminated elite from sub-elite players. Among U19s, the following tests differentiated elite from sub-elite players: VJ, 2kg MBCT, WSLS, 20-m/40-m linear speed, 60-s Push Up, One-Repetition Maximum Back Squat (IRM BS), 1RM Bench Press (BP), Repeated High-Intensity Exercise (RHIE), Tackling and Passing Ability. Elite Zimbabwean schoolboy rugby players were significantly leaner, slower, and "weaker" than their international/regional counterparts.

Conclusion: The results suggest important physical fitness characteristics and rugby-specific game skills for future identification of potentially talented players at U16/U19 categories.
