Swimming is an interesting, active, and healthy way to spend leisure time.
Swimming has a long history. In the Prehistoric era, people had to swim across the river for food. Swimming was the basic skill to survive in the fight with other people or beasts.
Modern swimming started in England. It became popular in Yorkshire region in 1660s. The first swimming pool was built in Liverpool George Wharf in 1828. The first Swimming Association was set up in England in 1837. And breaststroke was widely used in swimming.
There were three swimming items in the first modern Olympics in 1896. But there was no widely accepted rule for swimming. So, in 1908 Federation International de Nation (FINA) was founded.
Nowadays, there are six major items of 32 small items of freestyle, breaststroke, butterfly, backstroke, medley and relay (freestyle and medley). It is the second only after the Track and Field in Olympic Games.
