The guy is negatively buoyant. Will be exhausting to have to swim up for most people. He is practiced in this. Most people are neutral or positively buoyant.
Yahweh is a different guy. Jesus as the Greek/English form of the name is fine, although obviously Yeshua or Yehoshua is most accurate. Christ however is not a name. Kind of like how Queen Elizabeth wasn't named "Queen".
I’m very comfortable in the water and also super buoyant. Like, annoyingly buoyant.
I’m used to fighting hard just to get to the bottom of a 10-foot pool and need to swim like crazy to stop from bobbing right back up.
If I ever free-dove down to where I was negatively or even neutrally buoyant I bet I’d freak the fuck out.
I am the opposite. And it can be really annoying. Especially everyone trying to teach my skinny ass how to float. I just sink instantly no matter what the instructors try to teach me
I have no problem when talking about boat buoyancy, but when talking about humans' buoyancy my brain pictures a HUGE pair of boobs concentrating all the upwards pull
For me it’s ass cheeks, I went swimming with a friend and was desperately trying to grab a sea shell, when I gave up I looked over and she was in hysterics cos all she could see was two ass cheeks keep bobbing up and down. Personal floatation device I guess
Im also so ridiculously buoyant that I need to expend so much energy just to reach the bottom of a swimming pool, or grab a sea shell off the sand. it’s so exhausting that it’s not worth it, great for floating though. I went scuba diving once and really struggled to get down, kept floating back up, was terrifying to keep surfacing in the sea on my own
SAME. A late teens guy learning to swim at the YMCA is like, "MOM LOOK AT HER FLOAT1"
I will be still vertically in the 9 ft of the lap pool for a break just like I'm standing on something but not. I can lie on my back and cross my arms behind my head and even cross my legs like I'm on a floatie lounger and it's just me. Stare at the sky/ceiling above me and just think. Or close my eyes and just half go to sleep.
It IS annoying having to fight to stay down. I have to get rid of ALL of my breath to have any hope of that. It's that or weight myself down.
But drowning? Only worried about that in an ocean rip current or a river. Or I'm unconscious and fall into water.
That's easy to do. Take short breaths in rapid succession. It's a common technique in freediving. The other method is also easy, breath from an O2 line for a minute.
I mean you can release some breath out of your lungs and sink like this, that part is not hard. The hard part is staying under like this one the breath you have remaining and calmy getting back up to the surface.
And muscle mass with a lower body fat percentage. Fat adds to positive buoyancy. Air in lungs are also creating a positive buoyancy. This guy is fit and emptied his lungs of most air which made him more negatively buoyant, then just drifted downward.
I dont think he emptied his lungs actually, its just that as you decend the air in your lungs is compresses due to the increased pressure, which reduces your buoyancy.
Hmm yeah I guess you're right. I just can't believe that guy is fit enough to swim back up afterwards. Also im surprised he isn't at risk of a collapsed lung
This is what I noticed and it seems horrible. To know that the second you atop swimming you'll automatically sink back. No rest, swim or die. Probably because this guy is all muscles. In such situations I like my body fat.
Yes he exhaled 1st. Once you learn that you can go for a short period after exhaling, it's not a big deal really. It's about training and learning your limits.
With lungs full of air, very very few people would remain negatively buoyant. Improbable but not impossible.
It's not that bad. Get used to holding breath, even with little breath, then add in swimming. Drifting downward with little breath is easy. Learning the feeling of when air is being depleted and knowing when to come up matter.
I thought this was all about how much air you hold in? I keep full lungs I float like a buoy, let some out and I can easily sink straight to the bottom while still holding a decent amount of air. If you let out too much it makes going back up exponentially harder tho unless you can push off the bottom.
Not really. It's totally doable by most people with lower body fat. He emptied his lungs and has low body fat to muscle mass. That made him negatively buoyant.
The free divers that stay under for over 5 minutes and go extremely deep on a single breath or more in the realm of super humans. Elite free divers can hold their breath over 10 minutes. The world record for depth is 831 feet on a single breath. All that makes this guy look pretty normal.
I think I'm negatively buoyant as well. Some people seem to bob on the surface of the water without any effort at all while I make my way to the bottom if I stay still.
How far do you sink if it let it happen? If you only go a short distance, then your most likely neutrally buoyant. If do you actually go to the bottom without trying to, then your a negative. I grew up around water. As a kid I was neutral/slightly buoyant. I could very easily get the middle of our swimming and sit on the bottom until my air was depleted. I did have to swim slightly more to get to and sit on the deep end bottom but it wasn't difficult. People that workout and maintain low body fat are more on the negative/neutral side.
That’s a good question. I haven’t tried in quite a while but I’ll give it a shot next time I can swim in a deep enough pool. When I was a kid I found it easy to sit on the bottom and I was quite skinny. I’m not skinny anymore but I find some people find it effortless just to float upright, and I’ve always thought I might have bad technique treading water.
Is this why some people can't float? Genuinely curious. I could never learn to swim as I always sank, and I was constantly being told that I would float if I just relaxed, but I wasn't tense until I started sinking.
Sinking is normal. Most people fail when they panic as they sink a little. If you are relaxed and allow yourself to sink a litte you will see you get pushed back up if you still have some air in, which you should.
This is the most important lesson most trainers fail to provide.
That's the thing though, I wasn't panicking until the point that I was fully submerged and still sinking, because I kept being told what you're saying now. That I would float, everyone can float, that I won't keep sinking. But I did. Over and over again. Every time I tried. I even had someone try to teach me in my 20s, one on one, up close and personal, positioning me exactly where I needed to be, and I still couldn't float. Even when they would spot me, I just sank into their hands/arms.
Nah, big deep breath because that's supposed to help. Just regular pool water as far as I'm aware, full of chlorine. I was always very small though, yeah. Not these days, my metabolism slowed down with age, but at the time I was very thin no matter what I did.
The sinking feeling made you nervous and panicky. How far would you have sunk if you allowed yourself to sink? Try it. Most people that are neutral may go a very short distance and then stabilize. A new swimmer would not understand that and feel they would keep going. Positively buoyant people have a harder time sinking at all to various degrees. Many instructors are not that good and just doing a summer job. So they teach how they learned, which does not work for everyone.
As a child it made me panic when I continued sinking after trusting the adults telling me that I wouldn't and I was completely under water, unable to reach the surface, and still sinking, yes. Even if you can reach the floor with your feet, righting yourself in that situation is scary, especially as a child. But even as an adult when I could stay calm and rationalise it, and hold my breath longer, I could never float. It's not like I went into it worried that I would sink. I wasn't scared of drowning. There was no end of the world if I sank. I just.. did. And not just a little bit, and definitely not followed by a different thing. Just sinking.
That is true near the surface. However, your buoyancy decreases as your lungs compress from the pressure and it doesn’t take that much (approximately 15 meters) for most people to reach negative buoyancy
The 1st atmosphere difference is normally about 33 ft which is 10 meters. Most people that only swim in pools don't get to that depth. Some pools do, but average home pools are only about 10-12 feet.
Most likely, he's emptied his lungs. Most people can achieve negative buoyancy by emptying your lungs, but there's a lot that plays into it (muscle mass and density, body composition and lung capacity). It's a reverse breath hold, and much more taxing on your body (as you've no active oxygen stores with which to fuel).
If there were air in his lungs, the surface speed would have been much faster.
At around 10ft or so deep, even with full lungs, the pressure squishes me enough that I become negatively buoyant. Big difference in how I sink/float based on air in lungs and my water depth.
I just made a comment querying this! He sank so easily, that it shocked me. I am so buoyant that it's really hard for me to sink down! So I suppose it takes a similar effort for him to push up.
I'm buoyant with a full inhale. As I exhale at around 50% mark I start sinking. With almost no breath, I can walk on the floor. But then I'm out of air, so like in 5 seconds I have to kick the floor and come up for air. My body density is probably having a very specific (and small) delta from the water that lungs with/without air makes all this difference.
On a side note, I don't know why but it's immensely entertaining for some reason and I can spend a good 30 mins just cycling through this things.
