Good morning, family of fast. Matt Mosman, the chief endurance officer over at EndurElite. Welcome to another episode of Busting the Bullshit.
On the chopping block today is does caffeine, like the type found in coffee or in pre-workouts like PerformElite, decrease blood flow and negatively impact endurance performance?
Now, I don't know where this myth came from, but here's this whole bullshit theory that's been spewed out over the last few years, is that, basically, caffeine vasoconstricts or decreases blood flow.
This decrease in blood flow decreases blood to working muscles and can decrease endurance performance or affect those sick pumps for all you gym bros, and that it's just...it's not a good idea to consume caffeine pre-workout whether you're running, lifting, biking etc. Now, is there any truth to this? Short and sweet, no. It's a bunch of malarkey.
Now, I'm gonna spare you the geek speak because there's a ton of stuff that happens on the physiological level when you consume caffeine.
