| Abstract | Caffeine, or 1,3,7-trimethylxanthine, is a purine alkaloid that significantly influences various biological processes and regulating pathways. It is a psychoactive drug that influences mental as well as physical health, including mood, performance, sleep, and cognition. Caffeine is the most commonly consumed ergogenic supplement with proven and researched ergogenic effects such as greater agility, power, reduced reaction times, increased focus, improved muscle contractility, and endurance, which are beneficial for sport (Paiva et al., 202l; Diaz-Lara, 2024). This study conducted a randomized single-blind crossover design with a 48-hour recovery period between trials to examine the acute effect of caffeinated pre-workout supplementation on male collegiate swimmers. Participants were randomly assigned to receive either a caffeine pill or a placebo on separate occasions. Each participant consumed a 4 mg/kg dosage of the caffeine pills or placebo, depending on their trial condition. Given the results, there was a significant decrease in time in the 50m freestyle among male collegiate swimmers in the Philippines with caffeine compared to a placebo t(9) = -3.21, p = 0.005. (Cohen’s d=-1.14). Given its popularity, more research is required to fully explore the acute effects of caffeine on specific sports such as swimming. |
