Swimmers compete to achieve the fastest time while covering a designated distance using a predetermined stroke (freestyle, backstroke, breaststroke or butterfly). Although no specific stroke is prescribed for freestyle events, all swimmers currently use the crawl, which is the fastest stroke.

At Rio 2016, 32 men's and women's events were held in the pool, including individual and relay races. At Tokyo 2020, there will be 35 events, with the addition of three new competitions: 800m freestyle (men), 1,500m freestyle (women) and 4×100m medley relay (mixed).

The sport's International Federation FINA was formed during the London 1908 Olympic Games, when a pool was used for the first time in Olympic competition and rules were standardized.

Essence of the sport

The importance of technique and tactics

The world's top male freestyle swimmers can swim 50m in about 21 seconds, generating extraordinary speed and power. In backstroke, swimmers lie on their backs and use their arms to slide across the water's surface. In butterfly, the swimmers' arms move symmetrically, accompanied by a coordinated leg kick, evoking a flying butterfly. In breaststroke, the only stroke in which swimmers move their hands forward through the water after making a stroke, the key is to produce maximum thrust and minimum drag.

Olympic athletes must hone every detail of their technique, including the diving start, the timing of kicks and turns and the angles through which they move their arms.

Elite swimmers must also pay attention to pacing as a tactic. For example, a swimmer might advance to the final round by swimming quickly during the first half of a preliminary race to establish a dominant time. In the final, that same swimmer might hold back during the first half so that he or she can put in a burst of speed later. Such tactics are an essential part of the sport's appeal.

In individual medley events, a single swimmer competes using all four strokes in the following order: butterfly, backstroke, breaststroke, freestyle. Since each swimmer has particular strokes in which he or she excels, swimmers' relative positions on the leaderboard sometimes change as the stroke changes. These races are thrilling and fun to watch.

Medley relays differ from individual medleys in that the following stroke order is used: backstroke, breaststroke, butterfly, freestyle. Teams usually include the top-performing athlete for each stroke, creating all-star match-ups. In the 4×100m medley relay (mixed) — a new event — teams consisting of two men and two women can choose who swims each stroke. Men and women may swim against each other at the same time, adding to the excitement.

In team relay events, it's important to shorten the changeover time — the time from one swimmer touching the wall to the next swimmer's legs leaving the starting platform. A poorly executed changeover can cause a team to lose their position in the race, or even to be disqualified if the outgoing swimmer sets off too early.

Outlook for the Tokyo 2020 Games

Changing styles driving new world records

Constant evolution of technique is leading to ever greater levels of performance. Seven world records were set during the finals at London 2012 and Rio 2016.

The 100m breaststroke typifies this trend. At Beijing 2008, Kosuke Kitajima (Japan) became the first person in the world to swim faster than 58 seconds. Kitajima's technique included a streamlined body position to minimise water resistance, lowering the position of his head after each breath for greater efficiency and a reduced number of strokes. This became the dominant style worldwide.

However, at Rio 2016, Adam Peaty (Great Britain) brought major change by achieving extraordinary speed through dynamic, fast-paced swimming that combined a large number of strokes with a powerful kicking movement. Peaty set a world record time of 57:13 and won the gold medal.

New techniques in freestyle, backstroke and butterfly are also emerging with each Olympic Games and driving ever faster times.

Recent years have seen more swimmers competing in multiple events. Katinka Hosszú (Hungary), for example, excels at the individual medley. At the same time, single-event specialists such as Peaty remain. This increasing division of the sport into multi-event swimmers and specialists promises to bring further innovation in the coming years.
