Better pre-workout… coffee or beetroot juice? – Part 1 (of 4)

Coffee Improves Endurance Performance.

Wake up, rush through your daily morning routine, and hurry out the door to make it to work on time. While waiting in the Timmy’s drive-thru line you can’t help but get an eerie feeling you forgot something. You continue on with full determination, knowing your morning “boost” is just a couple cars away. Does this sound like you?

Coffee is one of the most regularly consumed beverages, because it provides the energy and focus needed to get through our hectic days. Coffee’s main ingredient, caffeine, acts as a central nervous system (CNS) stimulator making us feel more alert and focused. In addition, coffee contains anti-oxidants, polyphenols, and tannins… all good for the body. For this reason, coffee has become a popular pre- workout choice of many athletes. But does it actually work?

Part 1 of this 4 part series will focus on coffee and its effects on endurance performance. Runners, cyclists, rowers, I have good news. COFFEE CAN IMPROVE PERFORMANCE!

In A 2016 review (1), coffee was reported to improve time to exhaustion trials by an average of 24% and time to completion trials by 3%… in a 2 hour race that’s over 3.5mins faster… can you say, new PR?!

These positive effects are largely due to caffeine blunting the inhibitory effects of adenosine. Adenosine is a neurotransmitter in the brain that “inhibits” the CNS. What you are left with are feelings of reduced perceived exertion, pain, and improved vigour during training. At the muscular level, caffeine aids in the excitation-contraction process by increasing Calcium flux. So far so good, right? Well it gets better… there does not seem to be a diuretic response or any other fluid level concerns that could hinder your performance… amazing!

Not an endurance athlete?

Stay tuned, next week I will discuss whether or not coffee can improve anaerobic, power related activities.
