97-651: The Championships are generally held over a two-week time-period in mid-to-late Summer, but in the most recent Summer Olympics years (2004, 2008, 2012, 2016 and 2020), the Championships were moved to the Spring to be moved away from the Summer Olympic Games. The swimming portion of these championships is considered one of the pre-eminent swimming competitions in the world. LEN also conducts an annual short-course (25 meters) swimming championship , which

194-410: A redwood or simulated wood surround, and are termed "portable" as they may be placed on a patio rather than sunken into a permanent location. Some portable spas are shallow and narrow enough to fit sideways through a standard door and be used inside a room. Low power electric immersion heaters are common with home spas. Whirlpool tubs first became popular in the U.S. during the 1960s and 1970s. A spa

291-460: A coin to be inserted in a slot, either as deposit or payment. There are usually showers – sometimes mandatory – before and/or after swimming. There are often also lifeguards to ensure the safety of users. Wading or paddling pools are shallow bodies of water intended for use by small children, usually in parks. Concrete wading pools come in many shapes, traditionally rectangle, square or circle. Some are filled and drained daily due to lack of

388-671: A custom size and shape or built to a standardized size, the largest of which is the Olympic-size swimming pool . Many health clubs , fitness centers , and private clubs have pools used mostly for exercise or recreation. It is common for municipalities of every size to provide pools for public use. Many of these municipal pools are outdoor pools but indoor pools can also be found in buildings such as natatoriums and leisure centers . Hotels may have pools available for their guests to use at their own leisure. Subdivisions and apartment complexes may also have pools for residents to use. Pools as

485-450: A drag suit include the depletion of proper stroke. This is caused by the swimmer's own fatigue. When the swimmer becomes more fatigued, different muscle groups become more tired. Consequently, the swimmer will try to engage another group of muscle to do the same thing, which can cause the stroke efficiency to drop. Elite and international swimming comprises the highest level of competition available to swimmers, including competitions such as

582-510: A feature in hotels are more common in tourist areas or near convention centers . Educational facilities such as high schools and universities sometimes have pools for physical education classes, recreational activities, leisure, and competitive athletics such as swimming teams. Hot tubs and spas are pools filled with water that is heated and then used for relaxation or hydrotherapy . Specially designed swimming pools are also used for diving , water sports, and physical therapy , as well as for

679-416: A filter system. Staff chlorinate the water to ensure health and safety standards. The Fédération Internationale de la Natation (FINA, International Swimming Federation) sets standards for competition pools: 25 or 50 m (82 or 164 ft) long and at least 1.35 m (4.4 ft) deep. Competition pools are generally indoors and heated to enable their use all year round, and to more easily comply with

776-543: A floating raft in the river. The coffee was kept hot over a fire; club members had to tread water and drink coffee at the same time. The last swimmers managed to overturn the raft, to the amusement of 150 spectators. The Amateur Swimming Association was founded in 1869 in England, and the Oxford Swimming Club in 1909. The presence of indoor baths in the cobbled area of Merton Street might have persuaded

873-476: 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. Swimming each stroke requires a set of specific techniques; in competition, there are distinct regulations concerning the acceptable form for each individual stroke. There are also regulations on what types of swimsuits , caps, jewelry and injury tape that are allowed at competitions. Although it

970-490: A high temperature, thereby heightening its strong chemical smell. Ozone is an effective bactericide and is commonly included in the circulation system with cartridge filtration, but not with sand media filtration due to clogging problems with turbid body fats. In the early 20th century, especially in Australia, ocean pools were built, typically on headlands by enclosing part of the rock shelf, with water circulated through

1067-426: A larger leisure center or recreational complex. These centres often have more than one pool, such as an indoor heated pool, an outdoor ( chlorinated , saltwater or ozonated ) pool which may be heated or unheated, a shallower children's pool, and a paddling pool for toddlers and infants. There may also be a sauna and one or more hot tubs or spa pools (" jacuzzis "). Many upscale hotels and holiday resorts have

1164-572: A long course pool. There are forty officially recognized individual swimming events in the pool; however the International Olympic Committee only recognizes 32 of them. The international governing body for competitive swimming is World Aquatics , which was known until 2023 as the Fédération Internationale de Natation ("International Swimming Federation"), or FINA. In open water swimming , where

1261-453: A physical disability) where gradual entry is useful. Indoor pools are located inside a building with a roof and are insulated by at least three walls. Built for year-round swimming or training, they are found in all climate types. Since the buildings around indoor pools are insulated, heat escapes much less, making it less expensive to heat indoor pools than outdoor pools (all of whose heat escapes). Architecturally, an indoor pool may look like

1358-686: A potential risk of underwater entrapment from the pump suction forces. However, commercial installations in many countries must comply with various safety standards which reduce this risk considerably. Home spas are a worldwide retail item in western countries since the 1980s, and are sold in dedicated spa stores, pool shops, department stores , the Internet, and catalog sales books. They are almost always made from heat-extruded acrylic sheet Perspex , often colored in marble look-alike patterns. They rarely exceed 6 m (65 sq ft) and are typically 1 m (3 ft 3 in) deep, restricted by

1455-447: A race. Due to waves created by the swimmers, it can be an advantage to swim closer to the center of the pool during a race. Due to this, World Aquatics regulations specify which lane each swimmer competes in based on previous times. In a ten lane pool this is as follows: Competitive swimming, from the club through to international level, tends to have an autumn and winter season competing in short course (25 metres or yards) pools and

1552-420: A semifinal or final. The clerk is also responsible for enforcing rules of the swim meet if a swimmer chooses to not show up ("No show" - NS, or "Did Not Swim" - DNS) to their events. Timekeepers : Each timekeeper takes the time of the swimmers in the lane assigned to them. Unless a video backup system is used, it may be necessary to use the full complement of timekeepers even when automatic officiating equipment

1649-665: A similar level of protection for the children residing in or visiting the house, although many pool owners prefer the visual aspect of the pool in close proximity to their living areas, and will not provide this level of protection. There is no consensus between states or countries on the requirements to fence private swimming pools, and in many places they are not required at all, particularly in rural settings. Inexpensive temporary polyvinyl chloride pools can be bought in supermarkets and taken down after summer. They are used mostly outdoors in yards, are typically shallow, and often their sides are inflated with air to stay rigid. When finished,

1746-547: A single dolphin kick may be added to the breaststroke pullout before the first breaststroke kick. In the past decade, American competitive swimmers have made the most use of the underwater dolphin kick, notably Olympic and World medal winners Michael Phelps and Ryan Lochte . World Championship pools must be 50 metres (160 ft) ( long course ) long and 25 metres (82 ft) wide, with ten lanes labelled zero to nine (or one to ten in some pools; zero and nine (or one and ten) are usually left empty in semi-finals and finals);

1843-560: A spring and summer season competing in long course (50-metre) pools and in open water. In international competition and in club swimming in Europe, the short course (25m) season lasts from September to December, and the long course (50m) season from January to August with open water in the summer months. These regulations are slowly being brought to competition in North America. As of right now, in club, school, and college swimming in

1940-662: A swimming pool for use by their guests. If a pool is in a separate building, the building may be called a natatorium . The building may sometimes also have facilities for related activities, such as a diving tank. Larger pools sometimes have a diving board affixed at one edge above the water. Many public swimming pools are rectangles 25 m or 50 m long, but they can be any size and shape. There are also elaborate pools with artificial waterfalls , fountains, splash pads , wave machines, varying depths of water, bridges, and island bars. Some swimming facilities have lockers for clothing and other belongings. The lockers can require

2037-561: A water garden to be a part of the system, offer different aesthetic options and can support amphibious wildlife such as snails, frogs, and salamanders, and even small fish if desired. A zero-entry swimming pool , also called a beach entry swimming pool , has an edge or entry that gradually slopes from the deck into the water, becoming deeper with each step, in the manner of a natural beach. As there are no stairs or ladders to navigate, this type of entry assists older people, young children and people with accessibility problems (e.g., people with

2134-638: Is Polyester. The main difference between competition and regular swimwear is that competition swimwear is tighter and compresses the muscles of the swimmers. Regular swimwear is easier to put on and more comfortable for leisure activities. The most used practice swimwear for men includes briefs and jammers . Males generally swim barechested . There was controversy after the Beijing Olympic Games in 2008 when many Olympic swimmers broke records an unprecedented number of times using revolutionary swimsuits that covered their entire legs. To highlight

2231-586: Is a completely separate, distinct event (typically held in early December). Historically, the Championships were first held in 1926, and included water polo prior to 1999 when the discipline was moved to the European Water Polo Championship . From 1973-1999 Europeans were held in years without a Summer Olympics or World Championships , save 1979 (1973 being the inception year of the World Championships; and 1999 being

2328-400: Is a private casual, relaxing pool, it may go from 1.0 to 2.0 m (3.3 to 6.6 ft) deep. If it is a public pool designed for diving, it may slope from 3.0 to 5.5 m (10 to 18 ft) in the deep end. A children's play pool may be from 0.3 to 1.2 m (1 to 4 ft) deep. Most public pools have differing depths to accommodate different swimmer requirements. In many jurisdictions, it

2425-723: Is a requirement to show the water depth with clearly marked depths affixed to the pool walls. Pools can be either indoors or outdoors. They can be of any size and shape, and inground or above ground. Most pools are permanent fixtures, while others are temporary, collapsible structures. Private pools are usually smaller than public pools, on average 3.7 m × 7.3 m (12 ft × 24 ft) to 6.1 m × 12.2 m (20 ft × 40 ft) whereas public pools usually start at 20 m (66 ft). Home pools can be permanently built-in, or be assembled above ground and disassembled after summer. Privately owned outdoor pools in backyards or gardens started to proliferate in

2522-468: Is a structure designed to hold water to enable swimming or other leisure activities. Pools can be built into the ground (in-ground pools) or built above ground (as a freestanding construction or as part of a building or other larger structure), 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

2619-444: Is a swimming pool which produces a visual effect of water extending to the horizon, vanishing, or extending to "infinity". Often, the water appears to fall into an ocean, lake, bay, or other similar body of water. The illusion is most effective whenever there is a significant change in elevation, though having a natural body of water on the horizon is not a limiting factor. Natural pools were developed in central and western Europe in

2716-402: Is also called a "jacuzzi" there, as the word became a generic after-plumbing component manufacturer; Jacuzzi introduced the "spa whirlpool" in 1968. Air bubbles may be introduced into the nozzles via an air-bleed venturi pump that combines cooler air with the incoming heated water to cool the pool if the temperature rises uncomfortably high. Some spas have a constant stream of bubbles fed via

2813-646: Is believed to be the oldest surviving swimming club in Britain. It was formed in 1844, in response to concerns over drownings in the River Medway , especially since would-be rescuers would often drown because they themselves could not swim to safety. The club used to swim in the River Medway, and would hold races, diving competitions and water polo matches. The South East Gazette July 1844 reported an aquatic breakfast party: coffee and biscuits were served on

2910-472: Is commonly used to accommodate water polo. USA Swimming (USA-S) swims in both metric and non-metric pools. However, the international standard is metres, and world records are only recognized when swum in 50 m pools (or 25 m for short course) but 25-yard pools are very common in the US. In general, the shorter the pool, the faster the time for the same distance, since the swimmer gains speed from pushing off

Evidence of recreational swimming in prehistoric times has been found, with the earliest evidence dating to Stone Age paintings from around 10,000 years ago. Written references date from 2000 BC, with some of the earliest references to swimming including

3201-417: Is used. A chief timekeeper assigns the seating positions for all timekeepers and the lanes for which they are responsible. In most competitions there will be one or more timekeepers per lane. In international competitions where full automatic timing and video placing equipment is in use timekeepers may not be required. Inspectors of turns : One inspector of turns is assigned to one or more lanes at each end of

Since the 1990s, the most drastic change in swimming has been the addition of the underwater dolphin kick. This is used to maximize the speed at the start and after the turns in all styles. David Berkoff became the first to use it successfully; at

3880-617: The 1830s in England. In 1828, the first indoor swimming pool, St George's Baths was opened to the public. By 1837, the National Swimming Society was holding regular swimming competitions in six artificial swimming pools , built around London . The recreational activity grew in popularity and by 1880, when the first national governing body, the Amateur Swimming Association was formed, there were already over 300 regional clubs in operation across

A plunge pool is a smaller, permanently installed swimming pool, with a maximum size of approximately 3 m × 6 m (10 ft × 20 ft). Construction methods for private pools vary greatly. The main types of in-ground pools are gunite shotcrete , concrete, vinyl -lined, and one-piece fiberglass shells. Many countries now have strict pool fencing requirements for private swimming pools, which require pool areas to be isolated so that unauthorized children younger than six years cannot enter. Many countries require

Another swimmer to use the technique was Denis Pankratov at the 1996 Olympics in Atlanta, where he completed almost half of the 100 m butterfly underwater to win the gold medal. The dolphin kick was rarely used in freestyle sprint races until 2008, when "technical" swimsuits were introduced to

4171-645: The European Championships and is updated after the 2024 European Aquatics Championships . Swimming (sport) 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 (e.g., in a sea or lake). 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

4268-512: The Olympics was the 1922 Women's Olympiad . Butterfly was developed in the 1930s and was at first a variant of breaststroke, until it was accepted as a separate style in 1952. FINA renamed itself World Aquatics in December 2022. Competitive swimming became popular in the 19th century. The goal of high level competitive swimming is to break personal or world records while beating competitors in any given event. Swimming in competition should create

4365-578: The United States after World War II and the publicity given to swimming sports by Hollywood films such as Esther Williams ' Million Dollar Mermaid made a home pool a desirable status symbol. More than 50 years later, the home or residential swimming pool is a common sight. Some small nations enjoy a thriving swimming pool industry (e.g., New Zealand pop. 4,116,900 – holds the record in pools per capita with 65,000 home swimming pools and 125,000 spa pools). A two-storey, white concrete swimming pool building composed of horizontal cubic volumes built in 1959 at

The long-course season takes place in 50-meter pools and lasts from April to the end of August with open water in the summer months. In club swimming in Australasia , the short course (25m) season lasts from April to September, and the long course (50m) season from October to March with open water in

4559-558: The availability of the raw sheet sizes (typically manufactured in Japan). There is often a mid-depth seating or lounging system, and contoured lounger style reclining seats are common. Upmarket spas include various jet nozzles (massage, pulsating, etc.), a drinks tray, lights, LCD flat-screen TV sets and other features that make the pool a recreation center. Due to their family-oriented nature, home spas are normally operated from 36 to 39 °C (97 to 102 °F). Many pools are incorporated in

The referee can disqualify (or DQ) any swimmer for any violation of the rules that they personally observe or for any violation reported to them by other authorized officials. All disqualifications are subject to

4753-528: The country. In 1844 two Native American participants at a swimming competition in London introduced the front crawl to a European audience. Sir John Arthur Trudgen picked up the hand-over stroke from some South American natives and successfully debuted the new stroke in 1873, winning a local competition in England. His stroke is still regarded as the most powerful to use today. Captain Matthew Webb

4850-457: The decision and discretion of the referee. Those who are disqualified may choose to contest their disqualification. In age-group level swimming, however, this is rare. Appeals are reviewed by a panel of officials instead of the deck referee or stroke judges who may have made the initial disqualification decision. Brands such as Arena , Speedo , TYR , and Adidas are popular regular swimwear brands. The most durable material for regular swimming

5044-454: The early and mid-1980s by designers and landscape architects with environmental concerns. They have recently been growing in popularity as an alternative to traditional swimming pools. Natural pools are constructed bodies of water in which no chemicals or devices that disinfect or sterilize water are used, and all the cleaning of the pool is achieved purely with the motion of the water through biological filters and plants rooted hydroponically in

5141-516: The events are swum in a body of open water (lake or sea), there are also 5 km, 10 km and 25 km events for men and women. However, only the 10 km event is included in the Olympic schedule, again for both men and women. Pool and open-water competitions are typically separate events, except at the World Championships and the Olympics. In competitive swimming, four major styles have been established. These have been relatively stable over

They were decorated with flights of steps, punkalas or pots of abundance, and scroll design. Swimming pools became popular in Britain in the mid-19th century. As early as 1837, six indoor pools with diving boards existed in London, England. The Maidstone Swimming Club in Maidstone , Kent

5432-419: The innovation of the pre-form composite method where mosaic tiles are bonded to the shell this enables commercial spas to be completely factory manufactured to specification and delivered in one piece. Hot tubs are typically made somewhat like a wine barrel with straight sides, from wood such as Californian redwood held in place by metal hoops. Immersion of the head is not recommended in spas or hot tubs due to

5529-484: The issue, in 2008, 70 world records were broken in one year, and 66 Olympic records were broken in one Olympic Games (there were races in Beijing where the first five finishers were swimming faster than the old world record). As of 1 January 2010, men are only allowed to wear suits from the waist to the knees. They are also only permitted to wear one piece of swimwear; they cannot wear briefs underneath jammers. This rule

Drag suits are used to increase water resistance against the swimmer to help them train for competitions. Other forms of drag wear include nylons, old suits, and T-shirts: articles that increase friction in the water to build strength during training, and thus increase speed once drag items are removed for competition. Some swimmers practice in basketball shorts over their bathing suit, wearing two bathing suits, or wearing an extra bathing suit with holes cut in

5723-784: The lanes must be at least 2.5 metres (8.2 ft) wide. They will be equipped with starting blocks at both ends of the pool and most will have Automatic Officiating Equipment, including touch pads to record times and sensors to ensure the legality of relay takeovers. The pool must have a minimum depth of two metres. Other pools which host events under World Aquatics regulations are required to meet some but not all of these requirements. Many of these pools have eight, or even six, instead of ten lanes and some will be 25 metres (82 ft) long, making them Short course . World records that are set in short course pools are kept separate from those set in long course pools because it may be an advantage or disadvantage to swimmers to have more or less turns in

They are: In competition, only one of these styles may be used except in the case of the individual medley, or IM, which consists of all four. In this latter event, swimmers swim equal distances of butterfly, then backstroke, breaststroke, and finally, freestyle. In Olympic competition, this event is swum in two distances: 200 and 400 meters. Some short course competitions also include

However, some professional swimmers who do not hold a national or world ranking are considered the best in regard to their technical skills. Typically, an athlete goes through a cycle of training in which the body is overloaded with work in the beginning and middle segments of the cycle, and then the workload is decreased in the final stage as

6111-479: The less hardy of the aquatic brigade to join. So, bathers gradually became swimmers, and bathing pools became swimming pools. In 1939, Oxford created its first major public indoor pool at Temple Cowley. The modern Olympic Games started in 1896 and included swimming races, after which the popularity of swimming pools began to spread. In the US, the Racquet Club of Philadelphia clubhouse (1907) boasts one of

6208-465: The material. Many swimmers also shave areas of exposed skin before end-of-season competitions to reduce friction in the water. The practice gained popularity after the 1956 Olympics, when Murray Rose and Jon Henricks came shaved and won gold medals for Australia. Freshly shaven skin is less resistant when in the water. In addition, a 1989 study demonstrated that shaving improves a swimmer's overall performance by reducing drag. The disadvantages of using

However, after the fall of communism , Christ the Saviour Cathedral was re-built on the site between 1995 and 2000; the cathedral had originally been located there. The highest swimming pool is believed to be in Yangbajain (Tibet, China). This resort is located at 4,200 m (13,800 ft) AMSL and has two indoor swimming pools and one outdoor swimming pool, all filled with water from hot springs . Length: Most pools in

6402-592: The pool was open to the sexes at different times with a break for bathers to climb in without fear of observation by the other sex. These were the forerunners of modern "Olympic" pools. A variation was the later development of sea- or harbour-side pools that circulated sea water using pumps. A pool of this type was the training ground for Australian Olympian Dawn Fraser . There are currently about 100 ocean baths in New South Wales , which can range from small pools roughly 25 metres long and "Olympic Sized" (50m) to

There are also regulations for color of lane rope, positioning of backstroke flags (5 metres from each wall), and so on. Pools claimed to be "Olympic pools" do not always meet these regulations, as FINA cannot police use of the term. Touchpads are mounted on both walls for long course meets and each end for short course. A pool may be referred to as fast or slow, depending on its physical layout. Some design considerations allow

6596-457: The pool. Each inspector of turns ensures that swimmers comply with the relevant rules for turning, as well as the relevant rules for start and finish of the race. Inspectors of turns shall report any violation on disqualification reports detailing the event, lane number, and the infringement delivered to the chief inspector of turns who will immediately convey the report to the referee. Judges of Stroke : Judges of stroke are located on each side of

6693-450: The pool. They follow the swimmers during their swim back and forth across the pool. They ensure that the rules related to the style of swimming designated for the event are being observed, and observe the turns and the finishes to assist the inspectors of turns. Finish judges : Finish judges determine the order of finish and make sure the swimmers finish in accordance with the rules (two hands simultaneously for breaststroke and butterfly, on

6790-417: The pools by flooding from tidal tanks or by regular flooding over the side of the pools at high tide. This continued a pre-European tradition of bathing in rockpools with many of the current sites being expanded from sites used by Aboriginal Australians or early European settlers. Bathing in these pools provided security against both rough surf and sea life. There were often separate pools for women and men, or

6887-399: The reduction of swimming resistance making the pool faster: namely, proper pool depth, elimination of currents, increased lane width, energy absorbing racing lane lines and gutters, and the use of other innovative hydraulic, acoustic and illumination designs. In the last two decades, a new style of pool has gained popularity. These consist of a small vessel (usually about 2.5 × 5 m) in which

6984-447: The referee will blow a long whistle that will tell the swimmers to step on the block. For backstroke events, the long whistle is the signal for the swimmers to jump into the water. The referee will then blow another long whistle, signalling the swimmers to grab the gutter or the provided block handle. Finally the referee will hand over the rest to the starter by directing their hand to the starter. Starter : The starter has full control of

7081-495: The regulations regarding temperature, lighting, and automatic officiating equipment. An Olympic-size swimming pool (first used at the 1924 Olympics ) is a pool that meets FINA's additional standards for the Olympic Games and for world championship events. It must be 50 by 25 m (164 by 82 ft) wide, divided into eight lanes of 2.5 m (8.2 ft) each, plus two areas of 2.5 m (8.2 ft) at each side of

7178-441: The rest of the building, but extra heating and ventilation and other engineering solutions are required to ensure comfortable humidity levels. In addition to drainage and automatic pool covers, there are a number of ways to remove the humidity present in the air in any wet indoor environment. Efficient dehumidification in the indoor pool environment prevents structural damage, lowers energy costs for cooling or heating, and improves

7275-478: The seating area of the pool, or a footwell area. This is more common as a temperature control device where the heated water comes from a natural (uncontrolled heat) geothermal source, rather than artificially heated. Water temperature is usually very warm to hot – 38 to 42 °C (100 to 108 °F) – so bathers usually stay in for only 20 to 30 minutes. Bromine or mineral sanitizers are often recommended as sanitizers for spas because chlorine dissipates at

7372-511: The short course season if a swimmer wanted to compete in a stroke they had just learned, a 25-yard/meter race is available to them, opposed to the long course season when they would need to be able to swim at least 50 meters of that new stroke in order to compete. There are several types of officials, which are needed to manage the competition. Referee : The referee has full control and authority over all officials. The referee will enforce all rules and decisions of World Aquatics and shall have

7469-594: The sport at the European Short Course Championships in Rijeka, Croatia. Technical-suited Amaury Leveaux set world records of 44.94 seconds in the 100 m freestyle , 20.48 seconds in the 50 m freestyle and 22.18 in the 50 m butterfly, spending more than half of each race submerged, more than any of his competitors. Subsequently, FINA made a rule that swimmers may not go farther than 15 metres underwater. In 2014, FINA rules that

7566-445: The start of a race with a loud noise (usually a beep or a horn) and flash from a strobe light. A starter sends the swimmers off the blocks and may call a false start if a swimmer leaves the block before the starter sends them. A starter may also choose to recall the race after the start for any reason or request the swimmers to "stand", "relax" or "step down" if they believe that (a) particular swimmer(s) has obtained an unfair advantage at

7663-492: The start. Clerk of course : The clerk of course (also called the "bullpen") assembles swimmers before each event, and organizes ("seeds") swimmers into heats based on their times. Heats are generally seeded from slowest to fastest, where swimmers with no previous time for an event are assumed to be the slowest. The clerk of the course is also responsible for recording and reporting swimmers who have chosen to "scratch" (not swim) their events after they have signed up or qualified to

7760-642: The summer months. Outside the United States, meters is the standard in both short and long course swimming, with the same distances swum in all events. In the American short course season, the 500-yard, 1000 yard, and 1650-yard freestyle events are swum as a yard is much shorter than a meter (100 yards equals 91.44 meters), while during the American long course season the 400 meter, 800 meter, and 1500-meter freestyle events are swum instead. Beginning each swimming season racing in short course allows for shorter distance races for novice swimmers. For example, in

7857-412: The swimmer approaches competition. The practice of reducing exercise in the days just before an important competition is called tapering . Tapering is used to give the swimmer's body some rest without stopping exercise completely. A final stage is often referred to as "shave and taper": the swimmer shaves off all exposed hair for the sake of reducing drag and having a sleeker and more hydrodynamic feel in

7954-426: The swimmer swims in place, either against the push of an artificially generated water current or against the pull of restraining devices. These pools have several names, such as swim spas , swimming machines , or swim systems . They are all examples of different modes of resistance swimming . Hot tubs and spa pools are common heated pools used for relaxation and sometimes for therapy. Commercial spas are common in

8051-418: The swimmers from the time the referee turns the swimmers over to them until the race commences. A starter begins the race by saying, "Take your mark." At this point, the swimmers will get into stationary positions, sometimes known as "point zero", in which they would like to start their race. After all swimmers have assumed their stationary position, the starter will push a button on the starting system, signaling

8148-414: The swimming pool area or sauna area of a health club or fitness center, in men's clubs, women's clubs, motels and exclusive five-star hotel suites. Spa clubs may have very large pools, some segmented into increasing temperatures. In Japan, men's clubs with many spas of different size and temperature are common. Commercial spas are generally made of concrete, with a mosaic tiled interior. More recently with

8245-450: The system. In essence, natural pools seek to recreate swimming holes and swimmable lakes, the environment where people feel safe swimming in a non-polluted, healthy, and ecologically balanced body of water. Water in natural pools has many desirable characteristics. For example, red eyes, dried-out skin and hair, and bleached swimsuits associated with overly chlorinated water are naturally absent in natural pools. Natural pools, by requiring

8342-483: The training of lifeguards and astronauts . Swimming pools most commonly use chlorinated water, or salt water, and may be heated or unheated. The " Great Bath " at the site of Mohenjo-Daro in modern-day Pakistan was most likely the first swimming pool, dug during the 3rd millennium BC. This pool is 12 by 7 metres (39 by 23 feet), is lined with bricks, and was covered with a tar-based sealant. Ancient Greeks and Romans built artificial pools for athletic training in

8439-658: The very large, such as the 50 × 100 m baths in Newcastle . While most are free, a number charge fees, such as the Bondi Icebergs Club pool at Bondi Beach . Despite the development of chlorinated and heated pools, ocean baths remain a popular form of recreation in New South Wales. A semi-natural ocean pool exists on the central coast of New South Wales; it is called The Bogey Hole . An infinity pool (also named negative edge or vanishing edge pool )

8536-428: The wall after each turn at the end of the pool. Width: The width of the pool depends on the number of swimming lanes and the width of each individual lane. In an Olympic swimming pool each lane is 2.5 meters wide and contains 10 lanes, thus making the pool 25 meters wide. Depth: The depth of a swimming pool depends on the purpose of the pool, and whether it is open to the public or strictly for private use. If it

8633-503: The water and air can be let out and this type of pool can be folded up for convenient storage. They are regarded in the swimming pool industry as "splasher" pools intended for cooling off and amusing toddlers and children, not for swimming, hence the alternate name of "kiddie" pools. Toys are available for children and other people to play with in pool water. They are often blown up with air so they are soft but still reasonably rugged, and can float in water. Public pools are often part of

8730-479: The water. Additionally, the "shave and taper" method refers to the removal of the top layer of "dead skin", which exposes the newer and richer skin underneath. This also helps to "shave" off mere milliseconds on your time. Swimming is an event at the Summer Olympic Games , where male and female athletes compete in 16 of the recognized events each. Olympic events are held in a 50-meter pool, called

8827-640: The world are measured in metres, but in the United States pools are often measured in feet and yards. In the UK most pools are calibrated in metres, but older pools measured in yards still exist. In the US, pools tend to either be 25 yards ( SCY - short course yards), 25 metres ( SCM -short course metres) or 50 metres ( LCM - long course meters ). US high schools and the NCAA conduct short course (25 yards) competition. There are also many pools 33 + 1 ⁄ 3  m long, so that 3 lengths = 100 m. This pool dimension

8924-873: The world is at DreamWorks Water Park within the American Dream shopping and entertainment complex at the Meadowlands Sports Complex in East Rutherford, New Jersey , United States, and the largest indoor pool in North America is at the Neutral Buoyancy Lab in the Sonny Carter Training Facility at NASA JSC in Houston. In 2021, Deep Dive Dubai , located in Dubai, UAE, was certified by

9021-551: The world's first modern above-ground swimming pools. The first swimming pool to go to sea on an ocean liner was installed on the White Star Line 's Adriatic in 1906. The oldest known public swimming pool in the U.S., Underwood Pool, is located in Belmont, Massachusetts . Interest in competitive swimming grew following World War I . Standards improved and training became essential. Home swimming pools became popular in

9118-516: Was enacted after the controversy in the Beijing Olympics and Rome World Championships. Women wear one-piece suits with thicker and higher backs for competition, though two-piece suits can also be worn during practice. Backs vary mainly in strap thickness and geometric design. Most common styles include: racerback, axel back, corset, diamondback, and butterfly-back/Fly-Back. There are also different style lengths: three-quarter length (reaches

9215-658: Was held in Scotland in 1892. Men's swimming became part of the first modern Olympic Games in 1896 in Athens . In 1902, the Australian Richmond Cavill introduced freestyle to the Western world. In 1908, the world swimming association, Fédération Internationale de Natation (FINA), was formed. Women's swimming was introduced into the Olympics in 1912; the first international swim meet for women outside

9312-564: Was so large that the lifeguards required kayaks for patrol. It was closed in 1971 due to low patronage. In Europe, the largest swimming pool opened in 1934 in Elbląg ( Poland ), providing a water area of 33,500 square metres (361,000 sq ft). One of the largest swimming pools ever built was reputedly created in Moscow after the Palace of Soviets remained uncompleted. The foundations of

9409-670: Was the first man to swim the English Channel (between England and France), in 1875. Using the breaststroke technique, he swam the channel 21.26 miles (34.21 km) in 21 hours and 45 minutes. His feat was not replicated or surpassed for the next 36 years, until T.W. Burgess made the crossing in 1911. Other European countries also established swimming federations; Germany in 1882, France in 1890 and Hungary in 1896. The first European amateur swimming competitions were in 1889 in Vienna . The world's first women's swimming championship
