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] |
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 ...

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 ...

Dysbarism
Dysbarism refers to medical conditions resulting from changes in ambient pressure. Various activities are associated with pressure changes. Underwater diving is the most frequently cited example, but pressure changes also affect people who work in other pressurized environments (for example, caisson workers), and people who move between different altitudes. Ambient pressure Ambient pressure is the pressure in the water around the diver (or the air, with caisson workers etc.). As a diver descends, the ambient pressure increases. At in salt water, it is twice the normal pressure than that at the surface. At 40 meters (a common recommended limit for recreational diving) it is 5 times the pressure than at sea level. Pressure decreases as we rise above sea level, but less dramatically. At 3000 feet altitude Altitude or height (also sometimes known as depth) is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. ...

Herbert Nitsch
Herbert Nitsch (born 20 April 1970) 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 . To date, he has achieved 33 official World Records across all freediving disciplines, and one world record in the traditional Greek discipline of Skandalopetra . He surpassed his own No Limit depth with a dive in June 2012 to , suffering injury in the process. Background Nitsch worked part-time as a pilot for Tyrolean Airways. Freediving Achievements and competition history Nitsch holds the No-Limits record, the title of "Deepest man on Earth" in which the diver can make use of a weighted sled to descend as far as possible and uses an air-filled balloon or other buoyancy device to return to the surface. Nitsch set the world re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spetses
Spetses ( el, Σπέτσες, grc, Πιτυούσσα "Pityussa", Arvanitika: Πετσε̱) is an upscale affluent island in Attica, Greece. It is included as one of the Saronic Islands. Until 1948, it was part of the old prefecture of Argolis and Corinthia Prefecture, which is now split into Argolis and Corinthia. In ancient times, it was known as Pityussa; Spetses is a borrowing from Italian ''spezie'' "spices". The island is now an independent municipality (pop. 4,027), with no internal boundaries within the municipality. The town of Spetses (pop. 4,001 in 2011) is the only large settlement on the island. The other settlements on the island are Moní Ayíon Pánton (pop. 0), Ligonéri (4), Ágioi Anárgyroi (18), Kouzoúnos (4). Also part of the Municipality of Spetses are the islands of Spetsopoula, Falkonera, and Velopoula (all uninhabited). The municipality has an area of 27.121 km2. An unusual aspect of Spetses is that no private automobiles are allowed within the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Decompression Sickness
Decompression sickness (abbreviated DCS; also called divers' disease, the bends, aerobullosis, and caisson disease) is a medical condition caused by dissolved gases emerging from solution as bubbles inside the body tissues during decompression. DCS most commonly occurs during or soon after a decompression ascent from underwater diving, but can also result from other causes of depressurisation, such as emerging from a caisson, decompression from saturation, flying in an unpressurised aircraft at high altitude, and extravehicular activity from spacecraft. DCS and arterial gas embolism are collectively referred to as decompression illness. Since bubbles can form in or migrate to any part of the body, DCS can produce many symptoms, and its effects may vary from joint pain and rashes to paralysis and death. DCS often causes air bubbles to settle in major joints like knees or elbows, causing individuals to bend over in excruciating pain, hence its common name, the bends. Individu ...
