Day 120 - Do you take a pre-workout supplement?
I personally don't. Even though I workout first thing in the morning, I stick with good old caffeine to, as I like to call it, "Shake out the cobwebs".
I know many people, however, that take a pre-workout supplement to help them wake up, and 'pump up', for their workouts. The active participant in many pre-workout supplements is 'NO' or nitric oxide. I actually did a bit of undergraduate research on NO, on my way to my B.Sc. in Biochem. But enough about me.
In a round about way, it is NO that is involved in the chemical reaction targeted in erectile dysfunction medications. How does that relate to pre-workout supplements you ask?
Nitric oxide is a powerful vasodilator, meaning it relaxes your blood vessels. This is theoretically ideal for body builders as it could therefore increase blood flow to the muscles.
Having said that, I came across a very interesting study from Mississippi State University that has found that pre-workout supps may very well be useless.
"In the current study, acute AAKG supplementation provided no ergogenic benefit, regardless of the subjects' training status", the researchers concluded. "Based on the current study an acute ingestion of AAKG is not recommended for healthy individuals to increase maximal strength and muscular endurance for resistance training exercises."
