The history of freediving

What is it -.. Ie diving apnea - people knew long ago. Obtaining food and spearfishing on the coast of Africa, Mesopotamia, the Far East and the New World were associated with a dip in the sea depths. To have survived the cultural phenomenon of divers in apnea - Ama diver in Japan, the Philippines, Bhajan, pearl divers in Polynesia. With about 60 years of the last century, the revival of the sport. The World Federation of Diving at the same time ratified records freedivers. Numerous violations of safety and health studies about the dangers of enthusiasm led to the cessation of activities of this organization. Freedivers but that did not stop, they continued to dive. And die. In the period from 1970 to 1990. register more tragic dives than during the existence of modern freediving.

Sports freediving

When we talk about high scores and achievements - we are talking about sports immersion apnea. This means that athletes do not use any devices for breathing underwater, and rely solely on their own skills. Modern freediving divided into disciplines held in the pool and in open water. When people talk about records and achievements, it is a sport freediving.

Freediving in the pool

The confined water competitions in the following disciplines:

  • STA - static breath-holding (the athlete holds his breath, lying in the water).
  • DNF - swimming underwater in length without fins.
  • DYN - diving in length with fins or monofin. Freediving - what is it? Diving apnea

Freediving Open Water

The specifics of these competitions - diving deep.

  • CNF - the most difficult type. Diver descends vertically downwards and rises up, using only the power of their own muscles.
  • CWT - dive and surfacing using fins or monofin.
  • FIM - free immersion. The athlete descends and climbs the rope.
  • VWT - dive with the load. The descent is done using a special trolley and lifted by means of their own muscles.
  • NLT - dive without restrictions. Descent is carried out by means of the load or trolley, and lifting gear with any optionally athlete.

The latter type is the most dangerous, and it takes only five athletes in the world of freediving. What is it - the athlete goes down with little or no insurance and very quickly reaches maximum depths.

Unlimited - Yesterday and Today

It started this extreme competition in 1949. Underwater photographer Raimondo Bucher (Italy) to the dispute has dived to a depth of 30 meters. Italian divers Ennio Falco and Alberto Novelli entered the competition, and went abroad the depth of 40 meters.

In 1960, Enzo Majorca dived to a depth of 49 meters, and in 1966 he improved result, lost by 54 meters.

Hundred meter line was broken by Jacques Maillol in 1983.

Modern record belongs to the Austrian freediver Herbert Nitsch - 214 meters in the category without limits (2007). This "the deepest man in the world" put the record 31 in this form of freediving.

What is it - the diver's reflex?

When a person is immersed to a depth of 50 meters where the pressure reaches 11 atmospheres, the diver triggered protection reflexes - the same as dolphins and whales.

  • Blood shift - at a certain depth, all the body's blood flows away from the limbs, heading into the chest. Since the body is saved from being crushed.
  • bradycardia - slow heart beat. Some divers at a depth of heart beats frequency 7 beats per minute. At a rate - 80 beats per minute. So the body reduces the oxygen demand of all tissues of the body, leaving it only to the brain.

How do they feel?

What happens in the body freediver and that he feels? Primarily, the oxygen partial pressure is reduced, hypoxia. At the same time, it increases the partial pressure of carbon dioxide develops hypercapnia. Add to that the "nitrogen narcosis" - the impact of high-pressure nitrogen on the nervous system. As a result, in some developing divers panic and fear in others - a state of euphoria. Both are dangerous manifestations - at a depth of losing self-control is lost. Another phenomenon that await divers - "negative buoyancy". This is when a field of 30 meters depth the athlete is no longer pops up and goes freely into the depths. It is a state of the coast described freedivers.

Equipment athlete

Equipment has high ergonomics and hydrodynamic qualities, less weight and absence of voids with air.

  • Freight belt to compensate for the buoyancy of the athlete. This flexible tube filled with lead dust or straps with lead weights. To save the horizontal position used trucks collars.
  • The suit neoprene with open pores. High elasticity, taxability, low thermal conductivity - the main characteristics of the suit. Dress him a hard time, even using special grease. In southern waters used costumes Lycra - it will not help against the cold, but save us from the stinging jellyfish.
  • The flippers freediver tougher and long (80 cm), and is used with a monofin galosh.
  • mask for freediving different minimum internal space, which prevents the production of crimp. Used and liquid glasses - they contain the space between the eye and the lens, which is filled with water.
  • The tubes are used for breathing between dives.
  • for freedivers Knives - it is not a weapon, and rescue tools. Freediving - what is it? Diving apnea

How else will it affect the body?

Constant breath holding training leads to positive changes in our body:

  • backup increases the transport of oxygen, which leads to increased physical and intellectual capacities.
  • normalized immune status and a nonspecific resistance, which increases the overall level of the body's resistance.
  • chronic fatigue disappears, normal and improves the quality of sleep.
  • There is the optimization of mental and emotional state and resistance to considerable nervous and emotional stress.
  • It is good practice for climbers. Freediving - what is it? Diving apnea

I can not

That's what most people think, and read freedivers people special. Let's try to dispel some of the myths associated with the immersion and apnea.

  • Freedivers - special. Even after the first session with an instructor, each can hold his breath for about 2 minutes. With the training progresses rapidly, not only the body but the mind. So that everyone can become a freediver.
  • Immersion Apnea is dangerous. At official competitions were not deaths over the past 20 years. Although the loss of consciousness for the ascent were. Live at all dangerous. And freediving is no exception. The main thing here - do not dive alone and observe safety rules.
  • For freediving to be a good swimmer. Is not a fact. Many professional swimmers hinders competitiveness to achieve harmony and concentration necessary when diving apnea.
  • Do not deeper than 15 meters - only such a depth for me. Many people set themselves such limitations, but novice freedivers quickly forget about them. Competitiveness and the excitement is still in our human nature.
