History of Swimming at the Olympic Games
At the first few modern Olympic Games, Swimming events were held in open water. At Paris in 1900, for instance, they took place in the River Seine. However, the rules were formalised in 1908, when the London Games staged the first Olympic Swimming competition to be held in a pool. Women’s events were introduced at the Stockholm 1912 Games.
Find out more about Swimming at the Olympic Games on the International Olympic Committee website.

The basics
There are four strokes used in Olympic competition: Freestyle (essentially, front crawl), Backstroke, Breaststroke and Butterfly. All four strokes feature in the Individual Medley and Medley Relay events. Swimmers also compete in the Freestyle Relay events.
Olympic races in the pool are conducted over a variety of distances, from 50m (one length of the pool) all the way up to 1500m (30 lengths). The first athlete to touch the electronic finishing touchpad at the end of the pool in each race is the winner.
For a complete set of rules, please refer to the website of the International Swimming Federation (FINA), governing body for the sport.

Competition format
Races start with heats, the number of which depends on the number of swimmers in the event. Swimmers are seeded according to FINA rules, based on the final entry lists. These seedings are used to determine the heat each swimmer starts in – the top seeds are placed in different heats. Seedings are also used to determine the lane each athlete swim in – the higher the seeding, the closer to the centre lanes of the pool.
For 50m, 100m and 200m events, the top 16 swimmers from the heats progress to the semi-finals, and the top eight from these compete in the final. As in the heats, the swimmers’ seedings are used to decide which semi-final they swim in and which lane they are allocated. In 400m, 800m, 1500m and relay events, swimmers progress from the heats straight to the final.

Officials
Swimming events need many officials including timekeepers, start and finish judges, stroke judges, turn judges and an overall chief referee who is in charge of the competition.

Keys to success
For all events, getting a good start is paramount. Different events have different starts, either by diving in or starting in the water. Good stroke technique can make the difference between winning and losing, as can making fast turns and a good finish. The winning swimmers should have all parts of their race technique honed to perfection, including the changeovers in the Relay events.

Breaking the rules
While the start for all swimmers is crucial, a false start results in disqualification. Judges also look closely to check that stroke and turning techniques are legal and that in the Relay events each swimmer touches the end of the pool before his/her teammate leaves the starting blocks. Infringements of any kind are reported to the chief referee, who decides on any penalty to impose.
