Several studies have demonstrated a link between caffeine intake before exercise and increased athletic performance. A report published in Sports Medicine refers to caffeine as a “powerful ergogenic aid,” and mentions that athletes can “train at a greater power output and/or train longer” after caffeine consumption.
Another study published in the British Journal of Sports Science found that subjects who consumed coffee before running 1,500 meters on the treadmill completed their run 4.2 seconds faster on average than the control group.
