摘要：Caffeine is an almost inevitable part of our daily diet. Until recently, caffeine was banned from sports. However, in 2004 caffeine was taken off the list of banned substances of the International Olympic Committee. Even before that, caffeine has been widely used as an ergogenic substance. Therefore, we will review its ergogenic benefits and underlying mechanisms. Dose and timing of ingestion will also be mentioned, as well as possible adverse affects of caffeine. Last but not least, we will address some ethical doubts about its ab(use) by athletes in order to improve performance.
