Define effect of Caffeine on athletes?

Caffeine is found in coffee, tea, colas and chocolates. Its doses at 3- 6 mg/d have been known to increase muscle contractility and aerobic endurance and also enhances fat metabolism. Caffeine in levels more than 15 mc in urine is unacceptable and will disqualify athletes. This level can be reached with the doses of 9-10 mg kg. Therefore, care must be taken by athletes undergoing drug, testing not to consume excessive amounts of caffeine before the event.
