A study led by sports scientists at Dublin City University has found that the performance enhancing benefits of caffeine are more apparent in athletes who do not drink caffeine-rich drinks such as tea, coffee, and energy drinks on a daily basis.
Researchers Dr Brendan Egan and Mark Evans from the DCU School of Health and Human Performance examined the impact of caffeine, in the form of caffeinated chewing gum, on the performance of 18 male team sport athletes during a series of repeated sprints. The athletes undertook 10 repeated sprints under conditions with and without two sticks of the caffeinated gum, which is equivalent to two strong cups of coffee.
