World Aquatics in the context of "Open water swimming"

This is a list of international sports federations , each of which serves as a non-governmental governing body for a given sport and administers its sport at a world level, most often crafting rules, promoting the sport to prospective spectators and fans, developing prospective players, and organizing world or continental championships. Some international sports federations, such as World Aquatics and the International Skating Union, may oversee multiple activities referred to in common parlance as separate sports: World Aquatics, for example governs swimming, diving, synchronised swimming, and water polo as separate "disciplines" within the single "sport" of Aquatics.

International sports federations form an integral part of the Olympic and Paralympic movements. Each Olympic sport is represented by its respective international sports federation, which in turn helps administer the events in its respective sport during the Games. For a sport to become an Olympic sport, its international sports federation must be recognized by the International Olympic Committee.

Freestyle is a category of swimming competition, defined by the rules of World Aquatics, in which competitors are subject to only a few limited restrictions on their swimming stroke. Freestyle races are the most common of all swimming competitions, with distances beginning with 50 meters (55 yards) and reaching 1,500 meters (1,600 yards), also known as the mile. The term 'freestyle stroke' is sometimes used as a synonym for 'front crawl', as the front crawl is the fastest surface swimming stroke. It is now the most common stroke used in freestyle competitions.

The first Olympics held open water swimming events, but after a few Olympic Games, closed water swimming was introduced. The front crawl or freestyle was the first event that was introduced.

An Olympic-size swimming pool is a swimming pool which conforms to the regulations for length, breadth, and depth made by World Aquatics (formerly FINA) for swimming at the Summer Olympics and the swimming events at the World Aquatics Championships. Different size regulations apply for other pool-based events, such as diving, synchronized swimming, and water polo. Less onerous breadth and depth regulations exist for lesser swimming competitions, but any "long course" event requires a course length of 50 metres (164 ft 0.5 in), as distinct from "short course" which applies to competitions in pools that are 25 metres (82 ft 0 in) in length (or 75 feet (22.9 m) in the United States). If touch pads are used in competition, then the distance is relative to the touch pads at either end of the course, so that the pool itself is generally oversized to allow for the width of the pads.

An Olympic-size swimming pool is used as a colloquial unit of volume, to make approximate comparisons to similarly sized objects or volumes. It is not a specific definition, as there is no maximum limit on the depth of an Olympic pool. The value has an order of magnitude of 1 megaliter (ML). Some style guides caution against the hyperbole of describing any relatively large pool as "Olympic-size[d]".

The World Aquatics Championships, formerly the FINA World Championships, are the World Championships for six aquatic disciplines: swimming, diving, high diving, open water swimming, artistic swimming, and water polo. The championships are staged by World Aquatics, formerly known as FINA (Fédération internationale de natation), the international federation recognised by the International Olympic Committee (IOC) for administering international competitions in water sports. The championships are World Aquatics' largest and main event traditionally held biennially every odd year, with all six of the aquatic disciplines contested every championships. Dr. Hal Henning, FINA's president from 1972 through 1976, and their first American President, was highly instrumental in starting the first World Aquatics Championships, and in retaining the number of swimming events in the Olympics, which gave an advantage to nations with larger, more balanced swim teams.

The championships were first staged in 1973 in Belgrade, Yugoslavia, with competitions held in swimming, diving, synchronised swimming and water polo. In 1991 open water swimming was added to the championships as a fifth discipline. In 2013 high diving was added to the championships as a sixth discipline. In 2017 the synchronised swimming discipline was renamed to artistic swimming.

The World Aquatics Athletes of the Year (formerly FINA Athletes of the Year) is a set of awards presented by World Aquatics (International Swimming Federation) and the FINA Aquatics World Magazine. Each recognises excellence in five categories of aquatic sports: swimming, diving, synchronized swimming, water polo and open water swimming. The award was inaugurated in 2010.

The front crawl or forward crawl, also known as the Australian crawl or American crawl, is a swimming stroke usually regarded as the fastest of the four front primary strokes. As such, the front crawl stroke is almost universally used during a freestyle swimming competition, and hence freestyle is used metonymically for the front crawl. It is one of two long axis strokes, the other one being the backstroke. Unlike the backstroke, the breaststroke, and the butterfly stroke, the front crawl is not regulated by World Aquatics. Hence, in "freestyle" competitive swimming events, any stroke or combination of strokes is permissible. This style is sometimes referred to as the Australian crawl although this can sometimes refer to a more specific variant of front crawl.

The face-down swimming position allows for a good range of motion of the arm in the water, as compared to the backstroke, where the hands cannot be moved easily along the back of the spine. The above-water recovery of the stroke reduces drag, compared to the underwater recovery of breaststroke. The alternating arms also allow some rolling movement of the body for an easier recovery compared to, for example, butterfly. Finally, the alternating arm stroke makes for a relatively constant speed throughout the cycle.

The world records in swimming are ratified by World Aquatics (formerly known as FINA), the international governing body of swimming. Records can be set in long course (50 metres) or short course (25 metres) swimming pools. World Aquatics recognizes world records in the following events for both men and women, except for the mixed relays, where teams consist of two men and two women, in any order.

• Freestyle: 50m, 100m, 200m, 400m, 800m, 1500m
• Backstroke: 50m, 100m, 200m
• Breaststroke: 50m, 100m, 200m
• Butterfly: 50m, 100m, 200m
• Individual medley: 100m (short course only), 200m, 400m
• Relays: 4 × 50 m freestyle relay (short course only), 4 × 100 m freestyle, 4 × 200 m freestyle, 4 × 50 m medley relay (short course only), 4 × 100 m medley
• Mixed relays: 4 × 50 m mixed freestyle (short course only), 4 × 100 m mixed freestyle (long course only), 4 × 50 m mixed medley (short course only), 4 × 100 m mixed medley

The ratification process is described in FINA Rule SW12, and involves submission of paperwork certifying the accuracy of the timing system and the length of the pool, satisfaction of FINA rules regarding swimwear and a negative doping test by the swimmer(s) involved. Records can be set at intermediate distances in an individual race and for the first leg of a relay race. Records which have not yet been fully ratified are marked with a '#' symbol in these lists.
