coffee may help relieve post-exercise soreness, a small study suggests. But researchers caution that one should not jump start drinking coffee to have such a pain-relieving effect because of side-effects of caffeine. The study of nine female college students shows that those who took a caffeine supplement before being subjected to eccentric stimulation, which would cause delayed muscle pain, felt much better than those who took a placebo. The study, led by Victor Maridakis at the University of Georgia in Athens, appears in the Journal of Pain. Delayed muscle pain would occur one or two days after one does some exercise to such a degree that it triggers so called eccentric contraction of the muscles. The symptom does not hurt the body much, but it may stop some people from continuing their exercising. The researchers believe that caffeine eases delayed muscle pain by inhibiting the activity of adenosine, a chemical released in response to injury, which would otherwise result in activation of pain receptors. The dose of caffeine used in the study can be found in two cups of coffee. But the authors of the study do not recommend using coffee as a measure to prevent the post-exercise soreness. |
