What exactly is it about the deadlift that makes people pass out all the time?

How bad is it if I get really close to passing out but don't fully black out? I've gotten to the point where my head and arms shake and I can't control it, but I can sort of keep my grip on the bar when this is happening so I don't flail around. My vision also blurs. This has happened multiple times already.

>can you stroke out
Like have a stroke or cause a heart attack by deadlifting? Maybe at extreme weights with shit breathing and form. Worst I've seen is people passing out or bursting some blood vessels. Nothing to really worry about desu.

I don't know but I only do 300 with hexbar and less with a straight bar and those both make me lightheaded. Usually it seems like it's the first couple sets that do it. My vision goes tunnel and dark and my body tingles like when you stand up too fast.

Yeah, if you can induce a nosebleed, can the same happen inside the brain? My granddad stroked out at 50. I'd rather be mauled by an angry grizzly than have a serious stroke.

It's an exercise you shouldn't do, mostly designed to injure. If you ever, ever have to life something heavy in real life you will never be advised to lift it like a deadlift. There's no need to ever do them unless you are a professional weight lifter.

>eople should know the effect this had on his body. According to Eddie, he suffered bleeding in the brain, symptoms of a concussion (he forgot his wife's name for weeks) and he temporarily lost his sight... All from this one lift.
Pure strength from pure dedication and pain.

>t. S ö y boy

Ok, I'll go light on deadlifts. Thank fuck I'll never be as strong as these people.

T. Shit deadlift

You can but you have to lift half a ton like Eddie did. The average deadlifter who doesn't compete really shouldn't worry about it as long as he controls his breathing and form. I'm up to 500x5 on deadlift and while it was a bit stiff to walk immediately after that's as bad as it got. I might (only happened once) be lightheaded after going for more volume (6x6 on deads fucking rocked me one day) with a lighter weight though but that's about it. Your body can take a lot of punishment.
Like these guys. Learn to breathe during a pull movement, retards.

Your muscles stop contracting when you're finished, which forces blood back to your heart during the exercise but is not compensated after. You should squat down low right after a particularly heavy set.

Breathing has fuck all to do with it

T. Shit form and deadlift

Oh look, yet another reason why deadlifts are dangerous.

Wait, you're supposed to breathe? Fuck.

>Learn to breathe during a pull movement
This is happening when I'm doing OHP press. I'm trying to breathe better. I just want to know if I'm harming myself in any way when I get these episodes.

now thats what i call.....
a skull crusher!

Medfag here. The valsalva maneuver is often the first intervention used in emergency departments to try and stop extremely fast heart beats. It is a concert of compensatory mechanisms in the body and can often lead to very strong drops in heart rate.

Valsalva maneuver initially creates an increase in intrathoracic or chest pressure (when bearing down). This compressive force on the aorta and heart chambers leads to a decrease in the stroke volume of heart, and thus cardiac output drops (cardiac output = heart rate x stroke volume).

To compensate, the body's pressure sensors encourage increased heart rate to maintain cardiac output. If stroke volume drops, but heart rate goes up, then a normal cardiac output can be maintained. People typically don't pass out during this phase of the maneuver.

When you stop bearing down, the chest pressure comes back down to normal, and the compression of the aorta and heart chambers stops. The body quickly senses this and terminates compensatory changes to increase heart rate in favor of those that decrease the heart rate (CO = HR x SV, if stroke volume returns to normal, heart rate can come down again to maintain normal cardiac output and ensure normal blood delivery to body).

The wild changes in heart rate and stroke volume can lead to inadequate cardiac output, and can sometimes result in sudden loss of perfusing pressure to the brain. Hence why some niggas feel woozy and pass out during deadlifts or other lifts. Why certain people have a propensity to pass out while doing it still confuses me, it may be up to the individual strength of their body's reflexive processes.

Hope that helps.

Jon Pall Sigmarsson had a heart attack and died while deadlifting due to a fuckton of steroids and a heart defect. He also did this.

Nice but how about the less scientific version for brainlets like me

Autonomic dysfunction. Caused by vaccinations and wireless devices. Former fucks up parasympathetic nervous system, latter fucks up hypothalamic adrenal axis.

So today i was deadlifting close to my 1 rm on axle,when i pulled bar felt burning sensation in lower groin like next to hip bone on left side,it wasnt like muscle burning but like temperature raised at this exact spot, i dont feel any pain now, should i worry about that?

What is the proper breathing method for deadlifting to prevent this from happening. I only exhale once I finish a rep, because I am under the impression that exhaling causes you to lose the bracing, which you need throughout the entire lift.

this does not help

Extensive effort and no breathe good make oxygen available to brain low. Brain shut body down in effort to make oxygen to brain be coming first. Hoping brainlet version of helps

Any medfags?pls

in english doc

Exertion forces heart to pump oxygenated blood at high rate to muscle tissue so it can do the deadlift. Due to this and likely incorrect breathing the brain receives less oxygen forcing the body into a shutdown mode i.e. passing out until normal oxygen levels are restored.

This dudes sounds like he was born with a fedora attached to his skull

Another medfag here, this is an issue of perfusion (blood going places) and autonomic dysfunction (your body's nervous system response) as opposed to oxygenation/ventilation (lungs taking in oxygen and breathing out CO2).

People can hold their breath for a while, and maintaining a good valsalva maneuver for a lift shouldn't take long enough to make you pass out from lack of oxygen.

What my other 200+ IQ compatriot is trying to say is: the physiology going behind doing heavy fucking deadlifts can temporarily interrupt normal blood flow to the brain. Some folks may have different (autonomic) responses to this and may be more likely to pass out.

Most lifters aren't going to experience light-headedness during or before the lift, rather they will experience this after. Again, immediately after the lift upon releasing the valsalva, you experience a drop in heart rate which will lead to less blood going to your brain. Hence what happened to the poor cunt in OP's gif.

Valsalva (aka bearing down) --> heart rate goes up --> maintain normal blood flow --> stop valsalva --> sudden drop in heart rate --> less blood to head --> fainting/dizzy

If you don't feel any current tingling, numbness, pain or loss of touch sensation to the area you're talking about, I wouldn't worry about it. See if it is reproducible during future lifting sessions. Touch the area, try to see if anything is poking out or bulging. This would possibly indicate a hernia and would be something to definitely visit a physician for. Is there a rash or change in skin? Do you still have full range of motion in the knee and hip on that side?

I dont feel any pain,how lon does it take to bulge to form,its been 3 hours and there is no lump.

You're never going to lift 500kg anyways. So dont limit yourself like a faggot

le manly beard & deadliffs

People forget to breathe properly when exerting themselves. Combine that with a sudden precipitous increase in blood flow to your legs and core and back and away from your brain and you pass out.

Correct it by breathing properly and with effort. Make proper breath control a genuine staple of your workout.

I think dehydration and stimulants have some explanatory power for why some people pass out and others don't, at least in a normal gym. If you drink coffee at work all day and not enough water and then go do heavy deads you're probably more likely to get lightheaded/lose consciousness.

Even jeff recommending dropping it once you hit your knees on the downward movement

I wish there were some studies on this shit. My theory is that it has to do with your CNS genetics

Nah it really is breathing senpai. Most of these people I see pass out aren't breathing nearly enough for the exertion their body incurs. Trust me your brain will shut you down no matter how strong you are if it feels oxygen levels are too low.

What's odd is I take a deep breath and brace (valsalva) during squats/deadlifts and dont exhale until the end of the rep. I've never come close to passing out even deadlifting 455. But I did get very lightheaded and get dim vision at the end of a heavy OHP attempt and I typically don't focus on valsalva as much for those

Me neither but that might mean you got better lung capacity than average. I'm studying medicine as well, so we did a spirometry course. I had a lung capacity of 6.6L and had a FEV1 of about 6.1. So it really can be that some of us got better lungs honestly.
My friend who lifts with me is of a shorter stature and I notice him getting way more lightheaded than I do

Did he died?
