Swimming

Swimming is the sport or activity of propelling oneself through water using the limbs. Competitive swimming is usually performed in a 25m or 50m pool, using various stroke styles. Some other officially regulated strokes by International Swimming Federation (FINA) include freestyle, butterfly, breastroke and backstroke. These four strokes combine to make up the medley events.

 

. Swimming as an exercise is popular as an all-around body developer and is particularly useful in therapy and as exercise for physically handicapped persons. It is also taught for lifesaving purposes.

SWIMING EQUIPMENTS

SWIMMING SUITS

Men’s swimwear include briefs and jammers. FINA has formulated some rules to prevent swimmers from taking advantage by wearing aerodynamic swim suits. They can wear only one piece of swim suit from the waist to just above their knees.
Women usually wear one-piece suits of various designs at the back. Some of the popular designs are racer back, axel back, corset, diamondback, and butterfly-back/Fly-Back.

SWIMMING CAP

Swaying hair induces drag and slows down the swimmer. Long hair might also obstruct vision. A swim cap is used to lock hair and reduce drag. It is made of stretchable materials like, latex, silicone, spandex or lycra.

SWIMMING GOGGLES

Swimmers use goggles to prevent water and chlorine from getting into their eyes. While swimming at open pools, swimmers might choose tinted goggles to neutralize glare. Some goggles are also made of vision correcting lenses.
