How Coffee Caffeine Cuts Muscle Soreness by Nearly Half

If you’ve ever hit the gym hard—only to wake up the next day feeling like your legs are made of cement—you’re not alone. Delayed-onset muscle soreness (DOMS) is a common hurdle for anyone starting or ramping up a fitness routine. But what if something as simple as your morning cup could help take the edge off?

The short answer? Yes. Researchers found that a dose of caffeine roughly equal to two cups of coffee reduced muscle soreness by 48% in women who rarely drank coffee or exercised. That’s a significant drop for anyone trying to push through post-workout stiffness.

The Study Behind the Soreness Relief

Published in The Journal of Pain, the research led by scientists at the University of Georgia focused on nine female college students. These participants were not regular coffee drinkers and didn’t exercise often. After putting them through one to two days of physical activity that triggered muscle soreness, the researchers tested how caffeine affected their pain levels.

How Caffeine Impacts Muscle Pain

Participants were divided into groups. Some were given a caffeinated drink containing the equivalent of about two cups of coffee (delivering a specific dose of caffeine), while others received a placebo drink without caffeine. Both groups then performed leg exercises designed to assess their pain response. The results showed that those who consumed caffeine experienced 48% less muscle soreness compared to the placebo group. Even during follow-up exercises, their pain levels remained 26% lower.

Who Benefits Most from Caffeine for Soreness?

The study noted a key limitation: the pain-relieving effect of caffeine was most noticeable in people who don’t regularly consume coffee. For habitual coffee drinkers, the impact was minimal. This suggests that the benefits are most pronounced in those who typically have low caffeine intake. If you’re already a daily coffee drinker, chugging an extra cup might not deliver the same soreness relief.

Frequently Asked Questions

How much caffeine reduces muscle soreness?

About the amount found in two cups of coffee—enough to cut muscle soreness by 48% in non-regular coffee drinkers, based on the University of Georgia study. The same dose also reduced pain during later exercise by 26%.

Does caffeine work for everyone?

No. The study found that caffeine significantly reduces soreness only in people who don’t usually drink coffee. Regular coffee drinkers saw little to no benefit, likely due to caffeine tolerance.

What kind of exercise causes the soreness this helps with?

The research looked at typical post-workout muscle soreness (DOMS) that occurs one to two days after physical activity—especially in people who don’t exercise often or are new to a fitness routine.

Can I just drink more coffee to avoid soreness?

Not necessarily. The study used a specific caffeine dose (about two cups’ worth), and drinking more coffee won’t necessarily increase the effect—especially if you already drink coffee daily, as tolerance reduces benefits.

Is this only for women?

The study used female participants, so the findings may not directly apply to men. However, the mechanism of caffeine affecting muscle pain is likely similar across genders, though individual responses can vary.
