Synchronised Swimming is all about grace under pressure, as athletes use pinpoint precision and immense stamina to deliver beautiful routines in the pool.

Having made its Olympic debut at the Los Angeles 1984 Games, the all-female event will be held at the dazzling Aquatics Centre during London 2012.

Field of play

Part of the pool used for Swimming events is used for this competition. The area used for Synchronised Swimming is 30m long, 25m wide and 3m deep.

History of Synchronised Swimming at the Olympic Games

Synchronised Swimming grew out of the ornamental water ballets of the late 19th and early 20th centuries, which became popular in Europe and the US thanks to pioneers such as Australian swimmer Annette Kellerman. The first competitions were held in the 1930s, five decades before the sport made its Olympic debut at the Los Angeles 1984.

The basics

Aided by underwater speakers, duets or teams of eight swimmers perform short routines to a musical accompaniment. Judges mark a variety of components during the course of a routine, including choreography, difficulty and execution.

Competition format

In the Duets event, each duet performs a technical routine and a free routine preliminary as part of the preliminary phase. The total combined scores determine which 12 duets progress to the final, where each of them performs a free routine final. The results are determined by the combination of the scores from the technical routine during the preliminary phase and the free routine final.

In the Teams event, each team performs a technical routine and a free routine. The total of the two scores determines the competition results.

Officials

In the technical routine, one panel judges the execution, including the required elements. The other panel is looking at the overall impression: choreography, synchronisation, difficulty and manner of presentation.

In the free routine, the technical merit judges score the difficulty and execution of strokes/movements as well as the synchronisation of the swimmers. The other panel is looking at artistic impression, which includes choreography, music interpretation and manner of presentation.

Keys to success

Although it looks deceptively graceful from the pool side, Synchronised Swimming is an extremely demanding sport calling for great strength, endurance and flexibility. Swimmers use nose clips to help them stay underwater for longer, but the sport still requires tremendous breath control.

Every detail of the routine is judged and swimmers must be perfectly synchronised - all eight of them in the Teams event - if they are to score highly.

Breaking the rules

Judges can award point deductions for a variety of infringements, including taking too long on the deck before the swimmers enter the pool, making deliberate use of the bottom of the pool or missing out any of the compulsory elements of the technical routine.

Jargon buster

Eggbeater - powerful way of treading water that allows the swimmer to perform arm movements while staying afloat.

Scull - underwater hand movements designed to move and support the body in the pool.
