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). [1] 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, constant weight, constant weight without fins,

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.

Natalia Vadimovna Molchanova was a Russian champion free diver, multiple world record holder, and the former president of the Russian Free Dive Federation. She has been described as "possibly the world’s greatest freediver".
Association Internationale pour le Développement de l'Apnée (AIDA) 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.
Herbert Nitsch is an Austrian freediver who has held world records in all of the eight freediving disciplines recognised by AIDA International. He is the current freediving world record champion and "the deepest man on earth". This title was given to him when he set a world record in the "No Limit" discipline at the depth of 214 meters. To date, he has achieved 33 official World Records across all freediving disciplines, and one world record in the traditional Greek discipline of Skandalopetra 107 m (351 ft). He surpassed his own No Limit depth with a dive in June 2012 to 253.2 meters, suffering injury in the process.
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).
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 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. 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.
William Trubridge is a New Zealand world champion and world record holding freediver.
Constant weight without fins (CNF) is an AIDA International 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.
Marcus Greatwood is a British freediving coach. He is most noted for his creation and development of "NT Style" Freediving, based on relaxation and breathing techniques.
Skandalopetra diving dates from ancient Greece, when it was used by sponge fishermen, and has been re-discovered in recent years as a freediving discipline. It was in this discipline that the first world record in freediving was registered, when the Greek sponge fisherman Stathis Chantzis dived to a depth of 83 m in July 1913. It consists of a variable ballast dive using a skandalopetra tied to a rope. A companion on a boat recovers the diver by pulling the rope up after the descent, and keeps a watch on the diver from the surface.

Olivia K. (Liv) Philip is a record breaking freediver and AIDA International instructor who represents Great Britain. In January 2011 she was awarded AIDA's Absolute Freediver Award 2010 for the highest combined score in six freediving disciplines: static apnea, dynamic apnea with fins, dynamic apnea without fins, constant weight with fins, constant weight without fins, and free immersion. In March 2011 she broke the UK women's dynamic, no fins record at the Great Northern Dive Competition, with a 111m swim.

Nataliia Zharkova is a 2017 freediving champion of Europe and Ukraine. Zharkova holds multiple records in the discipline of freediving. She was also a freediving runner-up champion of the world in 2013. She is the first Ukrainian and the second woman to ever dive below the arch of the Blue Hole vertical underwater cave in Dahab, Egypt, on a single breath.
Alessia Zecchini is an Italian freediver who set world and Italian records in free diving.
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 to descend along the line with or without the use of his 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.
