Constant Weight Apnea
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).

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 surfa ...

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 200 ...

Monofin
A monofin is a type of swimfin typically used in underwater sports such as finswimming, free-diving and underwater orienteering. It consists of a single or linked control surface (fluid dynamics), surfaces attached to both of the diver's feet, emulating the Cetacea#Fluke, fluke of Cetacea, Cetaceans like whales or porpoises. The arrival of the monofin in the early 1970s led to the breaking of all finswimming world records by the end of the decade due to the improved performance possible when used instead of two ordinary swimfins. Use To differentiate between the use of monofins and conventional fins, the latter are sometimes referred to as stereo fins or bi-fins. The monofin swimmer extends arms forward, locking hands together, locking the head between the biceps, in a position known as Streamline (swimming), streamline position. The undulating movement starts in the shoulders, with maximum amplitude towards the hips; the legs almost don't bend to transfer the movement to th ...

Constant Weight Bi-fins
Constant weight bi-fins, denoted by the acronym CWTB in competition notation, is a competitive freediving discipline wherein the freediver wears a pair of bi-fins (or stereo, as opposed to a monofin) to descend along the line with or without the use of their arms. Pulling on the rope or changing ballast will result in disqualification; only a single hold of the rope is allowed in order to turn and stop the descent and start the ascent. The diver is prohibited from using a dolphin kick; doing so will result in disqualification of the day's dive. For AIDA International officiated freediving competitions, bi-fins was previously included under the umbrella term of constant weight (CWT) in competition. Prior to 2019, competitors wanting to use bi-fins in competition would compete under the category of constant weight alongside those using a monofin. In 2019, AIDA formally separated Constant Weight Apnea with Bi-fins (CWTB) into its own category for competition. Following the rule chang ...

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.

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%.

Dynamic Apnea Without Fins (DNF),
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, free immersion, cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Free Immersion Apnea
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.
