Watch this video, all in one breath!

that was done in a couple of different shoots, u can see the clock in his and in 1 and in the other u cant, cool nonetheless
 
i got to 1:20 i was pretty impressed with myself

this should just be a how long can yo hold ur breath thread

People who do deep free diving are nuts. Not even the holding the breath part, that's all mental. But being able to pressurize your ears that quickly is not right, especially without being able to breathe.
On a side note, on the way out, why not just drop the weight belt? There were obviously people down there who could have brought it out for him.
 
this is real for sure he holds the world record free dive and this is nothing compared to that dive
 
not necessarily. if he is an experienced diver, which he obviously is, his ears are probably pretty loose. i can drop down to 120 ft. without even having to equalize. my ears just do it on their own. My old man is the same way. I'd guess that this guy is in that club, too.
3-4 min underwater without a breath though is intense. i can stay down for a couple of minutes (free diving), but that's about my max.
 
no the first vid isn't real

it's just artistic

the filmer and diver have both said so and it's been posted on yahoo and w/e

i made it to like 0:30 :/
 
I got 2:45, the trick is, to take like 20 deep and slow breaths in the nose out the mouth. It slows down your heart rate so your body won't need as much oxygen.
 
I've been told you should hyperventelate a few times just before holding your breath too (after the deep slow breaths).
 
2:52 CLAIM... but i've been practicing holding my breath for a while now and i've slowly increased it from 1:30...

but that video is not real. when you have your breath held under water you float, and he just falls.
 
I he goes up too fast he can get Decompression sickness which wouldn't be very nice.

1:20 before I started coughing: i have a fever atm.
 
No he can't. Decompression sickness (The Bends) comes from breathing pressurized gas, and then changing depths/altitudes too quickly. After breathing pressurized gas, you must give your body ample time to dissipate the mixes from your bloodstream as you return to "normal" pressure and surface level "oxygen"/gas mix.
And I'm just going to throw out that holding your breath while sitting at a computer has got nothin' on doing it under water, while physically exerting yourself, and with no option but to make it to the top, or die. I'll bet a lot of you dudes could pull out damn near another minute if needed. It's amazing what the human body can do. Your mind is your biggest roadblock.
 
Sorry, meant to further explain that since he took his air (gas mix) from the surface to depth, and then returned to surface, then he doesn't have t worry about slow releasing the extra gasses that his body would have taken on if he had breathed that air at 300 feet.
If my explanation sucks, sorry, but it's late.

Decompression sickness in breath-hold divers: A review.

Lemaitre F, Fahlman A, Gardette B, Kohshi K.

Faculty of Sport Sciences, University of Rouen, Mont-Saint-Aignan,

France.

Although it has been generally assumed that the risk of decompression

sickness is virtually zero during a single breath-hold dive in humans,

repeated dives may result in a cumulative increase in the tissue and

blood nitrogen tension. Many species of marine mammals perform extensive

foraging bouts with deep and long dives interspersed by a short surface

interval, and some human divers regularly perform repeated dives to

30-40 m or a single dive to more than 200 m, all of which may result in

nitrogen concentrations that elicit symptoms of decompression sickness.

Neurological problems have been reported in humans after single or

repeated dives and recent necropsy reports in stranded marine mammals

were suggestive of decompression sickness-like symptoms. Modelling

attempts have suggested that marine mammals may live permanently with

elevated nitrogen concentrations and may be at risk when altering their

dive behaviour. In humans, non-pathogenic bubbles have been recorded and

symptoms of decompression sickness have been reported after repeated

dives to modest depths. The mechanisms implicated in these accidents

indicate that repeated breath-hold dives with short surface intervals

are factors that predispose to decompression sickness. During deep

diving, the effect of pulmonary shunts and/or lung collapse may play a

major role in reducing the incidence of decompression sickness in humans

and marine mammals."

Decompression sickness following breath-hold diving.

Despite convincing evidence of a relationship between breath-hold diving

and decompression sickness (DCS), the causal connection is only slowly

being accepted. Only the more recent textbooks have acknowledged the

risks of repetitive breath-hold diving. We compare four groups of

breath-hold divers: (1) Japanese and Korean amas and other divers from

the Pacific area, (2) instructors at naval training facilities, (3)

spear fishers, and (4) free-dive athletes. While the number of amas is

likely decreasing, and Scandinavian Navy training facilities recorded

only a few accidents, the number of spear fishers suffering accidents is

on the rise, in particular during championships or using scooters.

Finally, national and international associations (e.g., International

Association of Free Drives [IAFD] or Association Internationale pour Le

Developpment De L'Apnee [AIDA]) promote free-diving championships

including deep diving categories such as constant weight, variable

weight, and no limit. A number of free-diving athletes, training for or

participating in competitions, are increasingly accident prone as the

world record is presently set at a depth of 171 m. This review presents

data found after searching Medline and ISI Web of Science and using

appropriate Internet search engines (e.g., Google). We report some 90

cases in which DCS occurred after repetitive breath-hold dives. Even

today, the risk of suffering from DCS after repetitive breath-hold

diving is often not acknowledged. We strongly suggest that breath-hold

divers and their advisors and physicians be made aware of the

possibility of DCS and of the appropriate therapeutic measures to be

taken when DCS is suspected. Because the risk of suffering from DCS

increases depending on depth, bottom time, rate of ascent, and duration

of surface intervals, some approaches to assess the risks are presented.

Regrettably, none of these approaches is widely accepted. We propose

therefore the development of easily manageable algorithms for the

prevention of those avoidable accidents."

A single dive won't give you DCS but who knows how many times he was diving at that time?
 
interesting. thanks for the articles. i have never seen, heard, or read of anyone bending from free diving. seen a few inexperienced scuba divers bend a few times, but never a free diver.
as noted in the article, the info is not widely accepted. the generally accepted theory is that due to the fact that you aren't breathing at pressure (depth), the short bottom times of free dives, and the excellent physical fitness of free divers (low body fat percentages reduce the risk of bending), then the chances of bending are virtually non-existent. however, it does make sense that repetitive extreme depth free dives with little surface interval time in between dives could potentially lead to dcs as there is some nitrogen absorption that occurs, but it's nothing like the absorption that results from breathing pressurized gas at depth.
it also makes sense that the increased use of scooters over the past few years would add to the risk as they minimize the physical exertion required which allows people in less than top physical condition to perform the sport. the scooter would also allow the diver to return to depth much more quickly as they don't need that resting period at the surface to recoup and recover.
I obviously can't attest to how many dives he did prior. I would think that when pushing the limits like that, then that trip down would be the first of the day. (that's fucking deep!) and even if it wasn't his first dive, i would guess that he would need a little time in between dives to mentally prepare for the next trip down. considering the low levels of nitrogen absorbed while free diving, decomp times shouldn't be too long. definitely nothing like scuba diving decomp times.
So I suppose I shouldn't have said that he CAN'T, but rather the risk of bending was probably pretty small.
 
no. I don't think the bens would affect him becaause he holds his breath the whole time?

But he cannot possibly hold his breath that far down and moving his muscles that much.

When you move your muscles in exccess it requires extra oxygen which he is not getting because of his held breath. I still call this video FAKE.
