Keeping with the topic of fluids and performance, let’s talk caffeine. Many athletes enjoy a little caffeine lift in the morning, during lunch breaks, before training and during competition. However, the question comes up regarding caffeine and performance. To caffeinate, or not to caffeinate. We can talk about caffeine as a part of a sports diet and try to help you determine if you want to take it, or leave it in regards to your performance.  Science does have proof that caffeine can be beneficial for athletic performance. Caffeine has been tested in many studies as an ergogenic aid (ability to enhance physical performance) for endurance and short term-high intensity exercise.
