Human Swimming - Purpose

Purpose

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 an 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.

Famous quotes containing the word purpose:

    In using the strong hand, as now compelled to do, the government has a difficult duty to perform. At the very best, it will by turns do both too little and too much. It can properly have no motive of revenge, no purpose to punish merely for punishment’s sake. While we must, by all available means, prevent the overthrow of the government, we should avoid planting and cultivating too many thorns in the bosom of society.
    Abraham Lincoln (1809–1865)

    Since I do purpose to marry, I will think nothing to any purpose that
    the world can say against it; and therefore never flout at me for what I have said against it; for man is a giddy thing, and this is my conclusion.
    William Shakespeare (1564–1616)

    To found a great empire for the sole purpose of raising up a people of customers, may at first sight appear a project fit only for a nation of shopkeepers. It is, however, a project altogether unfit for a nation of shopkeepers, but extremely fit for a nation that is governed by shopkeepers.
    Adam Smith (1723–1790)
