SwimmingSwimming is a technique to move unaided through water. This article

concentrates on humanswimming a popular recreational activity and a competitive sport.

There are many health benefitsof swimming but it also has queAre you a

good swimmer Can you swim at all With practice technique can convert a slow oraverage

swimmer to at least a moderately fast swimmer. Since speed converts directly

intodistance the same techniques that improve speed also aid one to move farther with the

sameeffort. The upper body and the legs should be kept as much as possible parallel to

the surface ofthe water. Dropped legs or a lowered upper body dramatically increase drag.

The hand should beextended forward of the head as much as possible. This increases the

average length at thewater-line substantially increasing speed. This is an effect long used

by boat designers andunconsciously used by quotnaturally good

itive swimmingCompetitive swimming is swimming with the goal

to maximize performance usually the speed ofswimming. Competitive swimming became

popular in the 19th century and currently comprises 32events 16 male events and 16

female events at the Summer Olympic Games. The Competitiveinternational governing

body of swimming events is the International Swimming Association. It iscurrently being

debated whether or not to include the 1500m freestyle as part of the female

tly the longest female event is the 800m tional

swimmingThe most common reason for swimming is probably recreation where the

swimmer enters thewater merely for enjoyment. Swimming is a good way to relax. Many

swimming styles are suitablefor recreational swimming. Most recreational swimmers

prefer a style that keeps their head out ofthe water and uses an underwater arm recovery.

Most recreational swimming takes place in poolswhere the water is calm. Therefore

Freestyle which does not work as well in rough water issuitable. However playing around

in rough water is a common source of recreation but issometimes dangerous due to the

risk of injury from rocks on the bottom of a lake or ng pools are popular

places for recreational swimming as are beaches lakes swimmingholes rivers and

sometimes tional swimmingA number of people enter the water and swim

as part of their work fishermen for example whomight dive into the water and swim for

economic ng is used to rescue other swimmers who are in distress. There

are a number ofspecialized swimming styles specifically for rescue purposes. Such

techniques are studied bylifeguards or members of the Coast Guard. The training of these

techniques also evolved intocompetitions such as surf ng is also done

for scientific research. Swimming is studied to improve the performancesof competitive

swimmers. Swimming is also used in marine biology to observe plants and animalsin

their natural environment. Other sciences may also use swimming. Konrad Lorenz for

exampleswam with geese as part of his studies of animal ng also has

military purposes besides the mere need to cross waters. A swimmer in thewater or under

the water can be difficult to detect especially at night. Military swimming is usuallydone

by Special Forces especially ones in the Navy. Swimming is used to approach a

locationgather intelligence or combat and to depart a location. This may also include

dropping into waterfrom an airplane or jumping in from a boat. Special equipment and

techniques are also used tofight with others in and under ng for

exerciseSwimming is a good form of exercise. Because the density of the human body is

approximatelysimilar to that of water the body is supported by the water and less stress is

therefore placed onjoints and bones. Furthermore the resistance against movement

depends heavily on the speed ofthe movement allowing the fine tuning of the exercise

according to ones ability. Thereforeswimming is frequently used as an exercise after

injuries or for the ance swimming is one form of swimming exercises. It is

done either for training purposes tohold the swimmer in place for stroke analysis or to

enable one to swim in a confined space forathletic reasons. Resistance swimming can be

done either against a stream of water set in motionby a usually self-contained mechanical

device often termed a swimming machine or by holdingthe swimmer in one place by

means of elastic ng is primarily an aerobic 有氧的 exercise due to

the relatively long exercise timerequiring a constant oxygen supply to the muscles except

for short sprints. As with most aerobicexercise it is believed to reduce the harmful effects

of stress. While aerobic exercises usually burnfat and help with losing weight this effect

is limited in swimming even though being in cold waterburns more food energy to

maintain body reason that swimming does not significantly reduce

weight is still poorly understood butseems to be related to the better heat conduction of

water. A number of reasons are y water cools the body much faster than

air and most researchers believe that subsequentlythe body aims to maintain a layer of fat

under the skin to keep the bodys temperature at a stablelevel. Secondly it is believed that

appetite decreases as your body temperature increases as forexample during exercise.

However during swimming the body is cooled down almost instantly asthe surrounding

water is usually cooler than the body temperature and some researchers believethat this

may actually increase the appetite. This assumption is not yet proven by y

fast swimming requires a high level of effort meaning sugars rather than fats are

-lasting exercise at lower intensity is better for fat-burning. Four.
