Caffeine was removed from the World Anti Doping Authority’s (WADA) list of banned substances in 2004, meaning athletes who compete in sports that are bound by WADA were able to consume caffeine without bans or sanctions. This change in the code led to athletes from a vast range of sports eager to experiment with the use of caffeine as an ergogenic aid. However, an individual’s response to caffeine is highly variable and can include both positive and negative side effects.
Caffeine was originally thought to improve endurance performance by increasing the utilisation of fats from adipose tissue and in the muscle cell, thereby “sparing” glycogen stores. However, recent studies have suggested that the benefits of caffeine may lie instead in its ability to act on the central nervous system, reducing the perception of effort and fatigue as well as directly stimulating the muscle. The stimulant effect of caffeine has been well recognised. Many people reading this article have no doubt grabbed a coffee as a quick and convenient “boost” when feeling tired and fatigued. It’s the caffeine that provides this effect.
