passing out after deadlift

[bbg420]

ok I just watched about 5 youtube vids of guys deadlifting ,standing up and passing out, why is that, it never happened to me but wondering why it happens ,one guy hit his face on dumbbell rack ,ouch, got to have something to do with bp I would think

holding their breath.....a good 5 to 10 sec. max

I've never passed out but I've been on the brink of it a few times. I can see how it would happen

People tend to focus to much on moving the weight they forget to breath, typically on their max...and then they hit the floor.

I've been real close to passing out before. Even saw stars. I broke a rib doing deads before.

As other's have mentioned, it's from holding their breath too long.

The medical term is called postexertional syncope. It's due too a sudden drop in blood pressure from exertion/hold your breath.

Gotta breathe.

VAGAL RESPONSE

A vagal episode or vasovagal response or vasovagal attack is a malaise mediated by the vagus nerve. When it leads to fainting, also known as a "syncope", it is called a vasovagal syncope, which is the most common type of fainting. Vasovagal syncope is most commonly found in adolescents and in younger adults.

Comes from bearing down to hard on vagal nerve to put it simple.

It's only ever almost happened to me once. I saw all the videos before and couldn't understand it, then I tried to pull an old PR when I really wasn't ready to. I pulled it, was thrilled, but as I was locking it out I definitely felt my consciousness start to go. It was really weird but I caught myself.

Bad form and not breathing. As they were lifting they most likely had there chin tucked into there chest, adding the extra weight on top of that will surely cut off the arteries that provide oxygen to the brain.

Interesting, I figured it had something to do with not breathing plus the pressure from lifting heavy. Never passed out myself but I have popped a blood vessel in my eye.
