Dynamic Apnea
Dynamic apnea is a discipline of competitive freediving, also known as competitive apnea. Dynamic apnea covers two of the eight competitive freediving categories recognised by the AIDA International (International Association for Development of Apnea): dynamic with fins (DYN) and dynamic without fins (DNF). Both disciplines require breath held dives where the diver travels in a horizontal position under water under their own power without aid/physical contact of a static surface, with the exception of the pool wall when done indoors. The records can only be recognized in pools of 25m or greater. When diving in the dynamic without fins category, divers will usually prefer the shorter 25m pools, so they can take advantage of the wall-kick. However, when diving in the dynamic with fins category, divers will usually prefer the longer 50m pools, so the wall-turn will not slow them down. The other categories recognized are: static apnea, no limit, variable weight Variable may ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freediving
Freediving, free-diving, free diving, breath-hold diving, or skin diving is a form of underwater diving that relies on breath-holding until resurfacing rather than the use of breathing apparatus such as scuba gear. Besides the limits of breath-hold, immersion in water and exposure to high ambient pressure also have physiological effects that limit the depths and duration possible in freediving. Examples of freediving activities are traditional fishing techniques, competitive and non-competitive freediving, competitive and non-competitive spearfishing and freediving photography, synchronised swimming, underwater football, underwater rugby, underwater hockey, underwater target shooting and snorkeling. There are also a range of "competitive apnea" disciplines; in which competitors attempt to attain great depths, times, or distances on a single breath. Historically, the term ''free diving'' was also used to refer to scuba diving, due to the freedom of movement compared with sur ...

AIDA International
Association Internationale pour le Développement de l'Apnée (AIDA) (English: ''International Association for the Development of Apnea'') is a worldwide rule- and record-keeping body for competitive breath holding events, also known as freediving. It sets standards for safety, comparability of Official World Record attempts and freedive education. AIDA International is the parent organization for national clubs of the same name. History AIDA was founded November 2, 1992 in Nice, France by Frenchmen Roland Specker, Loïc Leferme and Claude Chapuis, with Specker as its first President. The AIDA Competitions started to take form in 1993. National clubs begin to form over all Europe in 1994–1995. AIDA became AIDA International in 1999. * In 1999 Sébastien Nagel, of Switzerland, replaced Roland Specker as the President. * Bill Strömberg, of Sweden, replaced Sébastien Nagel as President in 2005. * Kimmo Lahtinen, of Finland, replaced Bill Strömberg as President in December 20 ...

Apnea
Apnea, BrE: apnoea, is the temporal cessation of breathing. During apnea, there is no movement of the muscles of inhalation, and the volume of the lungs initially remains unchanged. Depending on how blocked the airways are ( patency), there may or may not be a flow of gas between the lungs and the environment, but if there's sufficient flow, gas exchange within the lungs and cellular respiration wouldn't be severely affected. Voluntarily doing this is called holding one's breath. Apnea may first be diagnosed in childhood, and it is recommended to consult an ENT specialist, allergist or sleep physician to discuss symptoms when noticed; malformation and/or malfunctioning of the upper airways may be observed by an orthodontist. Cause Apnea can be involuntary—for example, drug-induced (such as by opiate toxicity), mechanically / physiologically induced (for example, by strangulation or choking), or a consequence of neurological disease or trauma. During sleep, people with seve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Static Apnea
Static apnea (STA) is a discipline in which a person holds their breath (apnea) underwater for as long as possible, and need not swim any distance. Static apnea is defined by the International Association for Development of Apnea (AIDA International) and is distinguished from the Guinness World Record for breath holding underwater, which allows the use of oxygen in preparation. It requires that the respiratory tract be immersed, with the body either in the water or at the surface, and may be performed in a pool or open water (sea, lake, river, etc.). Static apnea is the only AIDA International discipline measuring duration, and one of the three disciplines considered for the international competitions by team, with constant weight and dynamic with fins. Beta blockers (doping in sport of freediving; prolong every type of apnea by reducing heart rate, blood pressure and cardiac output) can prolong static apnea for up to 20%.

No-limits Apnea
No-limit apnea is an AIDA International freediving discipline of competitive freediving, also known as competitive apnea, in which the freediver descends and ascends with the method of his or her choice. Often, a heavy metal bar or "sled" grasped by the diver descends fixed to a line, reaching great depths. The most common ascension assistance is via inflatable lifting bags or vests with inflatable compartments, which surface rapidly. The dives may be performed head-first or feet-first. This form of diving is considered extremely dangerous by diving professionals. No-limit apnea has claimed the lives of several divers. Challenges The three main differences between free diving disciplines that involve diving to depth and those that occur at the surface are that you can not interrupt the dive, there are periods where work is performed and the diver is impacted by direct effects of pressure. Records The current no-limit world record holder is Herbert Nitsch with a depth of set on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Free Immersion
Free immersion (FIM) is an AIDA International freediving discipline in which the freediver dives under water without the use of propulsion equipment, but only by pulling on the rope during descent and ascent. Performances may be done ''head first'' or ''feet first'' during the descent, or a combination of the two. The current record holders are Petar Klovar (Croatia) with a depth o132m (433ft) set on 6 Oct 2022 in Kaş, Antalya, Turkey, William Trubridge (New Zealand) with a depth of 124 meters (406 feet), set on 16 June 2016 in Dean's Blue Hole, Bahamas and Sayuri Kinoshita (Japan) with 97 meters (318 feet), set on 26 July 2018 in the Bahamas The Bahamas (), officially the Commonwealth of The Bahamas, is an island country within the Lucayan Archipelago of the West Indies in the North Atlantic.

Constant Weight
Constant weight (CWT) is a freediving discipline recognised by AIDA, the International Association for the Development of Apnea, in which the freediver descends and ascends using their monofin and/or with the use of their arms without pulling on the rope or changing his ballast; only a single hold of the rope to stop the descent and start the ascent is allowed. Constant weight is one of the eight disciplines considered for international competition, the others being constant weight bi-fins (CWTB), constant weight without fins (CNF), static apnea (STA), dynamic apnea without fins (DNF), dynamic with fins (DYN), free immersion (FIM), and dynamic apnea bi-fins (DYNB).

Constant Weight Without Fins
Constant weight without fins (CNF) is an AIDA International (International Association for Development of Apnea) freediving discipline in which the freediver descends and ascends by swimming without the use of fins or without pulling on the rope or changing his ballast; only a single hold of the rope to stop the descent and to start the ascent is allowed. Constant weight without fins is the depth discipline of freediving that is most challenging, because of the physical effort needed to swim without assistance. Challenges The main differences between free diving disciplines that involve diving to depth and those that occur at the surface are: the dive cannot be interrupted, there are periods where work is performed and the diver is impacted by direct effects of pressure.
