Caffeine Supplementation on Movement Patterns and Reactive Agility in Rugby Sevens Matches
NCT06612463 · Status: COMPLETED · Phase: EARLY_PHASE1 · Type: INTERVENTIONAL · Enrollment: 8
Last updated 2024-10-01
Summary
Caffeine is widely used by rugby players for its performance-enhancing effects. The main questions it aims to answer are: (1) the impact of caffeine supplementation on various performance metrics, including distance covered at different speeds, acceleration, deceleration, collisions, and repeated high-intensity efforts; and (2) reactive agility, across four matches over two consecutive days in collegiate male rugby sevens players.A position-matched, double-blind, randomized crossover design was employed, with six male collegiate rugby players (mean height: 1.78 ± 0.09 m, mean weight: 81.3 ± 9.2 kg) participating in two trials. Each trial consisted of a two-day tournament, with two matches per day. Movement was monitored using global positioning system units.
