Caffeine Improves Physical and Cognitive Performance during Exhaustive Exercise

PainSci summary of Hogervorst 2008?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided at the bottom of the page, as often as possible. ★★★☆☆?3-star ratings are for typical studies with no more (or less) than the usual common problems. Ratings are a highly subjective opinion, and subject to revision at any time. If you think this paper has been incorrectly rated, please let me know.

Caffeine really will “significantly improve” not only endurance performance, but “complex cognitive ability during and after exercise.” The researchers studied 24 well-trained cyclists, giving them either 100mg of caffeine or a placebo and then testing their endurance and their mental function during and after workouts. The signal was loud and clear: caffeine consumption boosted their performance.

Sign me up! I’ve already pretty much embraced caffeine as one of those rare pleasures in life that has minimal downsides — this is just gravy.
