Researchers at the University of Georgia in the United States reported in the latest issue of the Journal of Pain that after testing nine female students who don't drink coffee regularly or exercise regularly, they found that as long as they consume a small amount of caffeine equivalent to about 2 cups of coffee, they can reduce muscle aches by 48%.

According to the report, respondents will feel muscle aches after a day or two of physical exercise. At this time, the researchers asked some of them to drink caffeinated drinks, others to drink alternative drinks, and then did leg exercises. Results The pain of the former was reduced by 48% compared with the latter, and it was reduced by 26% in the subsequent exercise.

The researchers pointed out that although caffeine can relieve exercise pain, it is often only effective for people who don't drink coffee often, but has limited effect on people who drink coffee often, so their research results are not applicable to coffee drinkers.
