Drinking coffee before exercise can effectively reduce pain

Robert Motel, a professor at the University of Illinois, has been studying the relationship between caffeine and exercise for seven years. He found that caffeine affects the parts of the brain and spinal cord responsible for dealing with pain, so he speculates that it can reduce pain caused by exercise. To prove this theory, Myrtle and the researchers organized experiments. They divided 25 healthy men in their 20s into two groups.
