What the study found
Caffeine improved throwing-test performance and some perceived-fatigue measures, but did not improve the recorded offensive or defensive actions during combat.
Participants and protocol
Twenty-two experienced traditional jiu-jitsu athletes, including women and men, completed caffeine and placebo conditions in a double-blind crossover study.
What this cannot establish
A benefit in a standardized fitness test need not transfer to competitive skill. These findings do not establish a marathon benefit, personal dose or long-term safety.
