The Effect That Caffeine Has On Sporting Performance

Caffeine is the most widely consumed supplement within the sporting industry, due to its performance enhancing benefits. Whether that's a cup of coffee, energy drink or even in tablet form, many athletes use this to give them an extra edge in their performance. But how effective is this supplement in enhancing our sporting performance?

What does caffeine do to your body?

Caffeine is a central nervous system stimulant, which means it speeds up the processes in your brain and body. When consumed, caffeine blocks the effects of adenosine, the body's chemical messenger that makes you feel tired. This can lead to improved alertness, concentration and energy levels. But its benefits don't stop there, especially when it comes to sporting performance.
