Swimming is an activity that burns lots of calories, is easy on the joints, supports your weight, builds muscular strength and endurance, improves cardiovascular fitness, cools you off and refreshes you in summer, and one that you can do safely into old age. In this article, I'll review the history of swimming, the benefits, the strokes, how to get started, what to wear, equipment you need, where to do it, and more. Human swimming
Is the self propulsion of a person through water or other liquid, for survival, recreation, sport, exercise or other reason. Locomotion is achieved through coordinated movement of the limbs, the body, or both. Humans are able to hold their breath underwater and undertake rudimentary locomotive swimming within weeks of birth, as an evolutionary response. Swimming is consistently found to be amongst the top recreational activities undertaken by the public, and in some countries, swimming lessons are a compulsory part of the educational curriculum. As a formalized sport, swimming features in a range of local, national and international competitions, including featuring in every modern summer Olympics. History
The sport of swimming has been recorded since prehistoric times; the earliest recording of swimming dates back to Stone Age paintings from around 7,000 years ago. Written references date from 2000 BC. Some of the earliest references to swimming include the Gilgamesh, the Iliad, the Odyssey, the Bible, Beowulf, Quran and other sagas. In 1778, Nikolaus Wynmann, a German professor of languages, wrote the first swimming book, The Swimmer or A Dialogue on the Art of Swimming (Der Schwimmer oder ein Zweigespräch über die Schwimmkunst). Competitive swimming as we know it today started in the United States started around 1800, mostly using breaststroke. Many Americans often used swimming competitions to settle differences in the frontier, such as property rights. In 1873, John Arthur Trudgen introduced the trudgen to Western swimming competitions, after copying the front crawl used by Native Americans. Due to a British dislike of splashing, Trudgen employed a scissor kick instead of the front crawl's flutter kick. Swimming was part of the first modern Olympic Games in 1896 in Athens. In 1902 Richmond Cavillintroduced the front crawl to the Western world. In 1908, the world swimming association, Fédération Internationale de Natation (FINA), was formed. Butterfly was developed in the 1930s and was at first a variant of breaststroke, until it was accepted as a separate style in 1952.

There are many reasons why people swim, from swimming as a recreational pursuit to swimming as a necessary part of a job or other activity. Some people may also be forced in to swimming involuntarily as a result of falling into water.
The largest reason for people swimming is as a recreation activity, with swimming consistently ranking as one of the physical activities people are most likely to take part in. Recreational swimming can be used for people to exercise, to relax or to rehabilitate. The support of the water, and the reduction in impact, makes swimming accessible for people who are unable to undertake activities such as running.
Swimming is primarily a cardiovascular/aerobic exercise due to the long exercise time, requiring a constant oxygen supply to the muscles, except for short sprints where the muscles work anaerobically. As with most aerobic exercise, swimming is believed to reduce the harmful effects of stress. Swimming can also improve posture.
There are several types of officials, which are needed to manage the competition....
