Wow! But I also wonder how he did that, because I couldn't see any weights to help him dive(?) and why did he have to "climb" to come up again? Not being picky, but genuinely curious (can't swim either, so perhaps my perceptions are way off :blush: ) Interesting find though Trips :D

No, it's real, and a women I believe holds the title for the deepest "free dive" ... one consolation TC, you don't need to be able to swim, just hold your breath for a wee while. ;)

Yep thats freediving alright, at least 1 a year is killed freediving..
They hold massive amounts of oxygen in the overexpanded lungs..and can hold there breaths for 5 minutes or more..

You'll see Guilliuame Nery's name on the list of famous divers at the bottom..Tanya Streeter is our girl from Britian/cayman islands who holds some of the womens world records..




Taken from Wiki


The human body has several adaptations under diving conditions[1][2], which stem from the mammalian diving reflex. These adaptations enable the human body to endure depth and lack of oxygen far beyond what would be possible without the reflex.

The adaptations made by the human body while underwater and at high pressure include:[1][2]

  • Reflex bradycardia: Drop in heart pulse rate.
  • Vasoconstriction: Blood vessels shrink. Blood stream directed away from limbs for the benefit of heart, lungs and brain.
  • Splenic contraction: Releasing red blood cells carrying oxygen.
  • Blood shift: Blood plasma fills up blood vessels in the lung and reduces residual volume. Without this adaptation, the human lung would shrink and wrap into its walls, causing permanent damage, at depths greater than 30 meters.
[edit] Training

Training for freediving can take many forms and be done on the land.

One example is the apnea walk. This consists of a preparation "breathe-up", followed by a short (typically 1 minute) breath hold taken at rest. Without breaking the hold, the participant then initiates a walk for as far as they can, until it becomes necessary to breathe again. Athletes can do close to 400 meters in training this way.

This form of training is good for accustoming muscles to work under anaerobic conditions, and for tolerance to CO2 build-up in the circulation. It is also easy to gauge progress, as increasing distance can be measured.

Before diving, performance-oriented freedivers hyperventilate to a certain degree, resulting in a lower level of CO2 in their lungs and bloodstream.[3] This postpones the start of stimulation to the breathing centre of the brain, and thus delays the warning signals of running out of air. As the oxygen level of the blood is not increased by hyperventilation, this is very dangerous and may contribute to shallow water blackout and deep water blackout.[2][4] Trained freedivers are well aware of this and will only dive under strict and first aid competent supervision. However this does not, of itself, eliminate the risk of deep or shallow water blackout. All safe freedivers have a 'buddy' who accompanies them, observing from within the water at the surface. Due to the nature of the sport, safety is an integral part of free-diving, requiring participants to be adept in rescue and resuscitation. Without proper training and supervision, free-diving/apnea/breath-hold diving is extremely dangerous.

[edit] History

Archaeologists said that people have been earning their sustenance from freediving since the 5th century BCE. The first nation which was famous for it was the haenyeo in Korea. They collected shells and sponges to sell to others. The Ama Divers from Japan began to collect pearls 2000 years ago.[4][5] But also the spearfishers around the Mediterranean Sea were important for the historical background for the movement of the apnea sport.
