Abstract

Background: Caffeine is one of the most popular ergogenic aids widely used by coaches and athletes. Caffeinated chewing gums can be rapidly absorbed and may improve endurance as measured by VO₂ max. This study investigates the effect of caffeinated chewing gum on the levels of VO₂ max among physically active individuals. Methods: A randomized, double-blind, placebo-controlled, matched-pair trial design was used. Twenty-two physically active men were recruited and completed this study. Participants were then divided into two groups: A caffeinated chewing gum group (CG) and a placebo group (PG), with eleven participants in each group. Results: No adverse effect was reported by the participants during this study. The findings showed that caffeinated chewing gum was not effective in improving right or left handgrip and back or leg dynamometer but effectively increased VO₂ Max (PG: 1.45±2.44 ml/kg vs CG: 4.14±2.12 ml/kg; P<0.012). Conclusion: This study concluded that a caffeine dose of ~180 mg or ~3 mg/kg body weight in chewing gum increases maximal oxygen uptake among physically active individuals.
