A cup of coffee for your muscles?  Scientists at the University of Georgia revealed that taking a caffeine supplement (equal to 2 cups of coffee) after exercise reduces muscle soreness more than pain relievers can.  Caffeine blocks a chemical that activates pain receptors. 

Adenosine is a chemical released as part of the inflammatory response to injury.  The theory is that caffeine eases delayed muscle pain by blocking the activity adenosine.  This chemical can activate pain receptors in body cells, indicates the study.  The pain relief with caffeine was stronger than that from painkillers like acetaminophen (Tylenol) and naproxen (Aleve).

Ibuprofen, has shown inconsistent results in studies and it is unclear whether the drug, which is sold under brand names like Advil and Motrin aids delayed muscle soreness.

Before taking a couple of cups of joe before your workout however, it is recommended to take careful consideration of the possible side effects of caffeine.

The negative side effects of caffeine are: increased feelings of anxiety, heart palpitations, increased blood pressure, upset stomach, increased urination and disrupted sleep.

Though most people are ‘normal responders’ to caffeine, some are hypersensitive to it and are at higher risk of side effects.

On the other end of the spectrum are the caffeine-resistant types.

People who drink a couple of cups of coffee a day tend to become desensitised to caffeine, the study indicates, and it is unclear whether a dose of caffeine would aid their post-workout muscle pain.
