Coffee relieves pain

Have you ever made a fitness plan and quit because you felt tired? If so, try drinking coffee before exercising, and you may be able to stick with it.

US researchers found that drinking coffee before exercise can effectively reduce pain caused by exercise, which works for people who drink coffee and those who don't.

Robert Motel, a professor at the University of Illinois who has been studying caffeine and exercise for seven years, has found that caffeine can affect the parts of the brain and spinal cord responsible for pain processing, presumably reducing pain caused by exercise.

To prove this hypothesis, Motel and the researchers organized experiments. The experiment stipulated that subjects should not consume caffeine on their own for 24 hours before exercise.

They divided 25 healthy men in their 20s into two groups. One group drank very little or no coffee, while the other consumed an average of about 400 milligrams of caffeine a day, the equivalent of drinking three to four cups of coffee.

The researchers first had the subjects ride exercise bikes to measure their maximum oxygen consumption. They were then assigned to two intense 30-minute exercise cycles.

Experiments have shown that drinking coffee before exercise can effectively reduce the pain caused by exercise. Therefore, it is advisable to drink a cup of coffee before exercise, especially when you have not exercised for a long time and just started to resume exercise.
