Caffeine’s performance-enhancing effects are well-documented. Most studies show measurable improvements in performance following a small dose, and as a result, caffeine is commonly found in gels, drink mixes, and other athletic supplements.
But most adults already consume caffeine each day. Habitual consumption causes tolerance, which is said to weaken caffeine’s ergogenic effect. As a result some athletes even reduce their coffee consumption around key events, in hopes of increasing the performance-enhancing ability of supplemental caffeine.
But does the science back this up? A systematic review and meta-analysis by Dr. Bryan Saunders and colleagues examine the evidence to find out. Dr Saunders joins our host Sarah Laverty on this episode of the Science of Getting Faster Podcast to discuss the review, its findings, and what it means for caffeine’s role in making you faster.
