A study published in the Journal of Science and Medicine in Sport looks at caffeine use by endurance athletes.
Researchers analyzed 40 peer-reviewed articles on placebo controlled trials during endurance races. They found that the effect size of caffeine’s performance enhancing benefits increases with the duration of the event.
