Type: article
Abstract: Caffeine ingestion is dated from many centuries. Caffeine is a natural compound that is found in many foods and beverages such as tea, coffee, colas and chocolates. It stimulates the Central Nervous System, cardiac function, blood flow and the release of adrenaline. Together with caffeine, adrenalin stimulates a huge variety of tissues, potentiate muscle contraction, and increases the rate of breakage of muscle and hepatic glycogen. It is well known that caffeine can increase the concentrations of free fat acids (FFA) at rest before exercise, but appears to be some controversy on plasma free fat acids levels during exercise. As some of these effects, in thesis, can improve performance, even recently the International Olympic Committee banned the use of this substance. Due to habituation and difficulty on ingestion control, caffeine is to be taken off of the IOC list.
