Racing of Swimming!

Hi!
Today we will discuss swimming races.

The swimming competition includes individual and team tests. In the mixed runs using the four styles of competition-front crawl, backstroke, breaststroke and butterfly-in a specific order for individuals and one for teams. In the relay events the teams consist of four swimmers who take turns, the total time determines which team wins.

In international competitions test length between 50 and 1,500 meters. World records are only recognized when pools are set to 50 m in length. 
Competition has become so strong that it has been necessary to define precise rules for different styles and to regulate the physical conditions: size and shape of the pool, equipment type, demarcation of streets, water temperature, all important elements determining a performance. Electronic devices for measuring and timing almost have replaced judges and timekeepers in swimming events.

Thanks! Bye.
