I once read that caffeine works by making your body release adrenaline. The article also said that adrenaline releases glucose from your liver, and that's why caffeine rushes feel similar to "sugar highs". Doesn't this mean that it would be bad to use pre-workout? Not only that, but wouldn't that also mean that a crash could not occur if you had complex carbs?
And thanks for the rep, Mike. |
Yes, caffeine usually makes your body release adrenaline, which in turn triggers your body to empty some of, if not all of the liver stores of glycogen, which is used to
regulate your body's blood glucose level. However with the adrenal response component your body goes into the "fight/flight" mode and isn't worried about regulating blood glucose, just getting all it can available to "fight/flight". Hence why you can "crash" after an adrenal response.
A similar effect can occur if you become glycogen depleted during an intense workout, without caffeine involvement. Your body will get glucose from wherever it's needed, including the liver stores, to keep the brain going, and not be able to regulate the blood glucose levels efficiently, if at all "crashing" again.
Adding in the complex carbs is fine to help offset those feelings, however if your body is in "fight/flight" it wont be worried about digesting anything, and simple sugars would be preferred. However some of the newer complex carbs (I believe glycomaize was one) are designed to pass thru the GI system far quicker and thus can act as simple sugars, while retaining the complex carb status.
Taking it pre-workout or not is all a personal preference and seems to be beneficial for some, if you are prepared for what it is going to do to you.
