Swimming

By Pere Cases

I have decided to write about swimming because it’s the sport I like most.

The basic principle of swimming is being able to float and move your arms and feet. The human body has a high water content and its density is close to the density of water so it is easy to float.

There are four styles of swimming: crawl, butterfly stroke, backstroke and breaststroke. Butterfly stroke and crawl are the fastest ones and the others are slower.

Competitive swimming became popular in the nineteenth century. The goal of competitive swimming is to improve constantly.

There are two types of long pools; one is 25 metres long, for regional competitions, and the other one is 50 metres long, used for national competitions and right up to the Olympic Games.
