There are multiple strategies that have been suggested to attenuate delayed-onset muscle soreness (DOMS). Caffeine has been shown to assist with blocking pain associated with DOMS. However, currently there is still controversy over the effects of caffeine use. Our meta-analysis results indicate that caffeine supplements reduce delayed-onset muscle soreness when compared to a placebo 48 h after exercise. However, at 24 h post-exercise, caffeine can reduce DOMS only in people who worked on resistant exercise. The CK used in this meta-analysis did not show any differences.
