Scientists uncover how caffeine boosts athletes’ performance

In a study published in Friday’s online issue of the journal Applied Physiology, Nutrition and Metabolism, researchers from McMaster University Medical Centre found that caffeine tricks an athlete’s brain into delaying the perception of pain and fatigue. More importantly, it also tricks muscles into releasing more of the calcium needed to contract and relax.

“The caffeine is allowing a little bit more calcium to be released into that muscle,” said Dr. Mark Tarnopolsky. “It would make that muscle contraction a little bit stronger, so you can actually either run at the same pace with less input, or run at a faster pace for the same input.” Research from the University of Guelph showed caffeine in high concentrations can actually have the opposite effect, which is one of the reasons it is no longer banned at the Olympics.

Ron Charles from CBC talks about it in the video below:
