Swimming is the self-propulsion of a person through water, or other liquid, usually for recreation, sport, exercise, or survival. Locomotion is achieved through coordinated movement of the limbs and the body to achieve hydrodynamic thrust that results in directional motion. Humans can hold their breath underwater and undertake rudimentary locomotive swimming within weeks of birth, as a survival response.
Drowning is a type of suffocation induced by the submersion of the mouth and nose in a liquid. Most instances of fatal drowning occur alone or in situations where others present are either unaware of the victim's situation or unable to offer assistance. After successful resuscitation, drowning victims may experience breathing problems, vomiting, confusion, or unconsciousness. Occasionally, victims may not begin experiencing these symptoms until several hours after they are rescued. An incident of drowning can also cause further complications for victims due to low body temperature, aspiration of vomit, or acute respiratory distress syndrome.
A swimsuit is an item of clothing designed to be worn by people engaging in a water-based activity or water sports, such as swimming, diving and surfing, or sun-orientated activities, such as sun bathing. Different types may be worn by men, women, and children. A swimsuit can be described by various names, some of which are used only in particular locations or for particular types of suit, including swimwear, bathing suit, bathing attire, swimming costume, bathing costume, swimming suit, swimmers, swimming togs, bathers, cossie, or swimming trunks, besides others.
A lifeguard is a rescuer who supervises the safety and rescue of swimmers, surfers, and other water sports participants such as in a swimming pool, water park, beach, spa, river and lake. Lifeguards are trained in swimming and CPR/AED first aid, certified in water rescue using a variety of aids and equipment depending on requirements of their particular venue. In some areas, lifeguards are part of the emergency services system to incidents and in some communities, lifeguards may function as the primary EMS provider.
A wave pool is a swimming pool in which there are artificially generated, large waves, similar to those of the ocean. Wave pools are often a major feature of water parks, both indoors and outdoors, as well as some leisure centres.
Finswimming is an underwater sport consisting of four techniques involving swimming with the use of fins either on the water's surface using a snorkel with either monofins or bifins or underwater with monofin either by holding one's breath or using open circuit scuba diving equipment. Events exist over distances similar to swimming competitions for both swimming pool and open water venues. Competition at world and continental level is organised by the Confédération Mondiale des Activités Subaquatiques (CMAS). The sport's first world championship was held in 1976. It also has been featured at the World Games as a trend sport since 1981 and was demonstrated at the 2015 European Games in June 2015.
A hot tub is a large tub full of water used for hydrotherapy, relaxation or pleasure. Some have powerful jets for massage purposes. Hot tubs are sometimes also known as "spas" or by the trade name Jacuzzi. Hot tubs may be located outdoors or indoors.
A swimming machine, also known as a resistance swimming apparatus, is a self-contained device powered by a pump, designed to facilitate stationary swimming for athletes or recreational users. This can be achieved by either propelling water past the swimmer or providing support for the swimmer, either within a water environment or on dry land.
Freediving blackout, breath-hold blackout, or apnea blackout is a class of hypoxic blackout, a loss of consciousness caused by cerebral hypoxia towards the end of a breath-hold dive, when the swimmer does not necessarily experience an urgent need to breathe and has no other obvious medical condition that might have caused it. It can be provoked by hyperventilating just before a dive, or as a consequence of the pressure reduction on ascent, or a combination of these. Victims are often established practitioners of breath-hold diving, are fit, strong swimmers and have not experienced problems before. Blackout may also be referred to as a syncope or fainting.
An automated pool cleaner is a vacuum cleaner that is designed to collect debris and sediment from swimming pools with minimal human intervention.
Swimming lessons are the process of learning to swim. In most countries there is a definition of a number of swimming levels that are reached in the process of the curriculum. The respective certificates of swimming tests are required for further training in aquatic abilities. Many countries have defined a minimum swimming level that children should reach by the end of primary education, in most cases with the help of school swimming classes being part of the normal curriculum.
Swimming pool sanitation is the process of ensuring healthy conditions in swimming pools. Proper sanitation is needed to maintain the visual clarity of water and to prevent the transmission of infectious waterborne diseases.
A drain is the primary vessel or conduit for unwanted water or waste liquids to flow away, either to a more useful area, funnelled into a receptacle, or run into sewers or stormwater mains as waste discharge to be released or processed.
A swimming pool, swimming bath, wading pool, paddling pool, or simply pool, is a structure designed to hold water to enable swimming or other leisure activities. Pools can be built into the ground or built above ground, and may be found as a feature aboard ocean-liners and cruise ships. In-ground pools are most commonly constructed from materials such as concrete, natural stone, metal, plastic, composite or fiberglass, and can be of a custom size and shape or built to a standardized size, the largest of which is the Olympic-size swimming pool.
The Virginia Graeme Baker Pool and Spa Safety Act (VGBA) is a United States law named after Virginia Graeme Baker, who died after sustaining a pool suction-drain injury in June 2002, when the suction from a spa drain entrapped her under the water. It is incorporated as Title 14 of the U.S. Energy Independence and Security Act of 2007. This act became enforceable law on December 19, 2008.
Swimming is an individual or team racing sport that requires the use of one's entire body to move through water. The sport takes place in pools or open water. Competitive swimming is one of the most popular Olympic sports, with varied distance events in butterfly, backstroke, breaststroke, freestyle, and individual medley. In addition to these individual events, four swimmers can take part in either a freestyle or medley relay. A medley relay consists of four swimmers who will each swim a different stroke, ordered as backstroke, breaststroke, butterfly and freestyle.
Life Saving Victoria is an Australian life saving organisation formed in 2002 from a merger of the Victorian Branch of the Royal Life Saving Society Australia and Surf Life Saving Victoria. Life Saving Victoria works to prevent drownings and other water related deaths and injuries in Victoria. Life Saving Victoria teaches local communities in Victoria about water safety, swimming and resuscitation. It also provides surf life saving services and patrols for beaches across the state. Life Saving Victoria is an emergency support agency to Victoria Police for water based emergencies.
The instinctive drowning response is an instinctive reaction that occurs in humans, particularly in non-swimmers, when close to drowning. It is focused on attempting to keep the mouth above water to the exclusion of useful effort to attract help or self rescue, and is often not recognized by onlookers. The reaction is characterized by lateral arm movements, a vertical posture, tilting back the head, and inability to keep the mouth above the water or talk. The suppression of rational behavior by panic can also endanger swimmers attempting to rescue the victim.
Water safety refers to the procedures, precautions and policies associated with safety in, on, and around bodies of water, where there is a risk of injury or drowning. It has applications in several occupations, sports and recreational activities.
The Harold Holt Memorial Swimming Centre is a public swimming pool complex located on the corner of High Street and Edgar Street, Glen Iris, Melbourne, Australia. Built in the 1960s by Australian architects Kevin Borland and Daryl Jackson, the Swimming Centre is considered to be a fine example of Brutalist architecture. Originally built in 1927 as a municipal swimming baths, the facilities were renovated in 1967 by Borland and Jackson to accommodate for higher swimming participation numbers. It is named in honour of Prime Minister Harold Holt, whose apparent drowning death was announced during its construction and who was the local member of parliament.
