Olympic-size swimming pool in the context of "Water polo"

This article lists rivers by their average discharge measured in descending order of their water flow rate. Here, only those rivers whose discharge is more than 2,000 m/s (71,000 cu ft/s) are shown. It can be thought of as a list of the biggest rivers on Earth, measured by a specific metric.

For context, the volume of an Olympic-size swimming pool is 2,500 m (88,000 cu ft). The average flow rate at the mouth of the Amazon is sufficient to fill more than 83 such pools each second. The estimated global total for all rivers is 1.2 million m³/s (43 million cu ft/s), of which the Amazon would be approximately 18%.

Michael Fred Phelps II (born June 30, 1985) is an American former competitive swimmer. He won more Olympic medals than any other athlete, a total of 28 medals across four Olympic Games. Phelps also holds the all-time records for Olympic gold medals (23), Olympic gold medals in individual events (13), and Olympic medals in individual events (16). At the 2004 Summer Olympics in Athens, Phelps tied the record of eight medals of any color at a single Games, held by gymnast Alexander Dityatin, by winning six gold and two bronze medals. Four years later, when he won eight gold medals at the 2008 Beijing Games, he broke fellow American swimmer Mark Spitz's 1972 record of seven first-place finishes at any single Olympic Games. At the 2012 Summer Olympics in London, Phelps won four gold and two silver medals, and at the 2016 Summer Olympics in Rio de Janeiro, he won five gold medals and one silver. This made him the most successful athlete of the Games for the fourth Olympics in a row.

Phelps is a former long course world record holder in the 200-meter freestyle, 100-meter butterfly, 200-meter butterfly, 200-meter individual medley, and 400-meter individual medley. He has won 82 medals in major international long course competitions, of which 65 were gold, 14 silver, and three bronze, spanning the Olympics, the World Championships, and the Pan Pacific Championships. Phelps's international titles and record-breaking performances have earned him the World Swimmer of the Year Award eight times and American Swimmer of the Year Award eleven times, as well as the FINA Swimmer of the Year Award in 2012 and 2016. Phelps earned Sports Illustrated magazine's Sportsman of the Year award due to his unprecedented Olympic success in the 2008 Games.

A swimming pool, swimming bath, wading pool, paddling pool, or simply pool, is a man-made structure designed to hold water to enable swimming and associated 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 ships. In-ground pools are most commonly constructed from materials such as concrete, natural stone, metal, plastic, composite or fiberglass, and may follow a standardized size, the largest of which is the Olympic-size swimming pool, or be of a custom shape.

Many health clubs, fitness centers, and private clubs have pools for their members, often used for exercise. In much of the world, local governments provide publicly-run pools. Some of these are outdoors; indoor pools are often part of a leisure centre. Many hotels have a pool for the use of their guests. Pools as a feature in hotels are more common in tourist areas or near convention centers. Many universities and other institutional communities provide pools for their members, often as part of an institution-specific athletic or recreational complex. Apartment complexes and residential subdivisions may provide a pool for the use of their residents. Private residences, particularly in areas with warm climates, may have their own pools.

The Pan Pacific Swimming Championships is a long course swimming event first held in 1985. It was founded as an alternative to the European Championships, for those countries that could not swim in those championships, in a manner similar to the Four Continents Figure Skating Championships which provide a similar 'continental' championships for non-European nations.

The meet was founded by its four Charter nations's swimming federations: Swimming Australia (Australia), Swimming Canada (Canada), Japan Swimming Federation (Japan), and USA Swimming (United States). As part of the Charter, hosting of the meet is to rotate among these four nations, with the meet being held in Japan every other championship. Initially, the meet was open to all countries that border the Pacific Ocean, giving the meet its name. This since has been expanded/opened to include other non-European countries wishing to participate, such as Brazil and South Africa.

The swimming competitions at the 2008 Summer Olympics took place from 9 to 17 August 2008 at the Beijing National Aquatics Centre. The newly introduced open water marathon events (10 km) were held on 20 and 21 August 2008 at Shunyi Olympic Rowing-Canoeing Park.

Swimming featured 34 events (17 male, 17 female), including two 10 km open-water marathons. The remaining 32 were contested in a 50 m long course pool within the Olympic Park.

The swimming competitions at the 2012 Summer Olympics in London took place from 28 July to 4 August at the Aquatics Centre. The open-water competition took place from 9 to 10 August in Hyde Park.

Swimming featured 34 events (17 male, 17 female), including two 10 km open-water marathons in Hyde Park's Serpentine Lake. The remaining 32 were contested in a 50 m long course pool within the Olympic Park.

An Olympic Park is a sports campus for hosting the Olympic Games. Typically it contains the Olympic Stadium and the International Broadcast Centre. It may also contain the Olympic Village or some of the other sports venues, such as the aquatics complex in the case of the summer games, or the main ice hockey rink for the winter games. The Olympic Park is often part of the "legacy" which provides benefit to the host city after the games have ended. As such it may subsequently include an urban park and a museum or similar commemoration of the games that were hosted there.

The 1908 Olympic organising committee specified "As far as possible all the competitions, including swimming, archery, fencing, wrestling, etc., will be held on the same site in which the amphitheatre for the track-athletics and cycling will be erected." Not every games has a centralised complex of this type. The 1992 and 2010 Winter Games had widely dispersed venues; "Whistler Olympic Park" was the venue for the nordic skiing events in 2010. Venues of the 2016 Summer Olympics in Rio de Janeiro were split among four "clusters" rather than concentrated in a single Park.
