Caffeine is a plant alkaloid found in many different products. (Archna 2008) Caffeine is categorized as a drug that stimulates the central nervous system and aids in mobilizing free fatty acids which increases the use of fats as an energy source. (Desbrow 2007) This substance when consumed is distributed in intracellular fluid after crossing the blood-brain barrier. This results in the central nervous system, cardiovascular system, and smooth and skeletal muscle tissues being affected (Desbrow 2007). Tea, coffee, chocolate, soda, energy drinks, and pharmaceutical products, are just a few of the many products that contain caffeine.

When asked to name different substances that aid athletic performance many people would respond steroids, or other drugs that are prevalent in the world of athletics. Many people simple overlook caffeine as an ergogenic aid. There are thousands of studies that have been done researching the ergogenic effects of caffeine in athletic performance. There are positive benefits to caffeine use as well as negative effects of caffeine use.
