Swimming is probably the most favoured sport in today’s date. It is the most popular sport which is included in Olympic Games. The sport is all about the propulsion of the body in the water combined by the leg and arm movements. For both Olympic Games and other world championships, the swimming race length were held in a closed swimming pool and the lengths were measured in meters. The events range from short sprints to longer ones, where swimmers compete over 50m to 400 m pool. The usual swimming competition allowed strokes such as freestyles, backstroke, breaststroke and butterfly.
