Consumption of caffeine in sports

The Australian Olympic Committee (AOC) considers that caffeine should belong to banned substances of the World Anti-Doping Agency. The president of the AOC John Coates affirms that caffeine induces addiction to sleeping remedies and tranquillisers.
It is known that the Australian swimmers who competed at the 2004 and 2008 Olympics administered sleeping pills Stilnox. Thus, John Coates confirms that application of caffeine led to usage of Stilnox.
Stilnox is ordinarily sold under the name Zolpidem. It is a sleeping remedy that is indicated to cure insomnia.
John Coates notes that sportspersons use caffeine in order to increase performance. Consumption of this substance leads to insomnia. So, athletes should use sleeping tablets in order to cure insomnia.
 The AOC and Swimming Australia desire to ban consumption of caffeine. It is their response to the disgrace connected with Grant Hackett. A doctor recommended using Stilnox to this swimmer at the time of the 2003 World Championships. As a result, Grant Hackett became addicted to this sleeping remedy.
Grant Hackett is a famous swimmer. He won certain competitions, including the 2000 Sydney Olympics, the 2004 Athens Olympics and the 2008 Beijing Olympics.
Alan Thompson, the former coach of the Australian Olympic Team, has also confirmed that intake of Stilnox is widely spread among Australian swimmers.
Stilnox was never on the list of prohibited drugs. Anti-doping agencies didn’t conduct tests to disclose usage of this preparation.
But when it comes to caffeine, previously it was prohibited by the WADA. But since it became widely spread and consumed in society, it was excluded from the list of forbidden substances.
John Fahey, the president of the WADA, states that the WADA made the right decision and excluded caffeine from list of banned medications. He confirmed that caffeine would not be included in the list of prohibited medicines again.
However numerous specialists confirm that caffeine is a performance enhancer, John Fahey contests this argument. He confirms that caffeine doesn’t impact on performance. He concludes that no any scientific literature describes capacity of caffeine to enhance performance.
