SYNCHRONISED Swimming was introduced at the London Games in 1948 but was only given competitive status in 1984 at the Games in LA.
It is a women-only event, and 104 athletes will be competing in London this summer.
- How it works
Pairs or teams of eight perform a short routine accompanied to music in front of a panel of 10 judges.
The judges are divided up, with one half awarding marks for artistry, while the other assesses technical merit.
- Synchronised Swimming in London
Synchronised Swimming events will be held at the Aquatics Centre, with duets and teams performing two routines – technical and freestyle.
Look out for: the Russians. They have claimed every gold medal in the past three games.
Not to be confused with: water aerobics.
Useless but informative fact: Synchronised swimmers can were nose clips, but not goggles.
Synchronised Swimming in two words: endurance, flexibility.
Synchronised Swimming takes place at the Aquatics Centre between Sunday 5 August and Friday 10 August.
