For two years, Steph Gaudreau gave up her daily cup of coffee. She switched to large mugs of herbal tea – not because caffeine was affecting her sleep or making her anxious, but to gain an edge in cross-country mountain bike racing.
Hoping to enhance the effect of caffeine as a performance aid, Gaudreau, who lives in San Diego, drank a cup of coffee on race day as she warmed up. Once that pre-race caffeine boost hit, Gaudreau, now a nutritional therapy practitioner and strength coach, said she felt a sense of euphoria, which helped her feel focused and mentally prepared for her race. The strategy paid off. In 2010, she took first place in a regional amateur biking race called the Kenda Cup.
Caffeine is the most widely consumed psychoactive substance in the world and one of the best studied. Scientists have been looking at caffeine’s effect on athletics since the 1900s. Although there is still some disagreement as to the exact mechanism by which caffeine consumption affects exercise performance, and whether taking a break from it until game day can give you an edge, scientists agree that a cup of coffee before working out can improve performance, whether you’re playing for the NBA or just running through your neighbourhood.
