==Speed and ergonomics==
The peak speed of the butterfly is faster than that of the front crawl due to the synchronous pull/push with both arms and legs, which is done quickly. Yet since speed drops significantly during the recovery phase, it is overall slightly slower than front crawl, especially over longer distances. Another reason it is slower is because of the extremely different physical exertion it puts on the swimmer compared to the front crawl.

The breaststroke, backstroke, and front crawl can all be swum easily even if the swimmer's technique is not the best. The butterfly, however, is unforgiving of mistakes in style; it is very difficult to overcome a poor butterfly technique with brute strength. Many swimmers and coaches consider it the most difficult swimming style. The main difficulty for beginners is the synchronous over-water recovery, especially when combined with breathing, since both arms, the head, shoulders, and part of the chest have to be lifted out of the water for these tasks. Once the efficient technique has been developed, it becomes a smooth, fast stroke.<ref>{{cite web|url=https://www.youtube.com/watch?v=R-639WuN-b0|title=YouTube|access-date=18 February 2017}}</ref>
==History==
{{Main|History of swimming}}
The [[International Swimming Hall of Fame]] credits Australian [[Cavill family|Sydney Cavill]] as the originator of the butterfly stroke. Cavill (1881–1945), the son of "swimming professor" [[Cavill family|Frederick Cavill]], was 220 yards amateur champion of Australia at the age of 16. He followed his famous brothers to America and coached notable swimmers at San Francisco's [[Olympic Club]].<ref>{{AuDB|first=J. G.|last=Williams|year=1979|id2=cavill-frederick-5536|title=Frederick Cavill|volume=7|access-date=18 February 2017}}</ref>
In late 1933, Henry Myers swam a butterfly stroke in competition at the Brooklyn Central YMCA.<ref>{{cite web|url=http://www.usaswimming.org/USASWeb/ViewMiscArticle.aspx?TabId=480&Alias=Rainbow&Lang=en&mid=799&ItemId=1709|title=Developed on the fly|website=[[USA Swimming]]|author=Tom Slear|date=May 2005|via=Splash Magazine|access-date=2017-02-18|url-status=dead|archive-url=https://web.archive.org/web/20071026222145/http://www.usaswimming.org/USASWeb/ViewMiscArticle.aspx?TabId=480&Alias=Rainbow&Lang=en&mid=799&ItemId=1709#|archive-date=2007-10-26}}</ref> The butterfly style evolved from the breaststroke. David Armbruster, swimming coach at the [[University of Iowa]], researched the breaststroke, especially considering the problem of drag due to the underwater recovery. In 1934 Armbruster refined a method to bring the arms forward over the water in a breaststroke. He called this style "butterfly".{{citation needed|date=April 2020}} While the butterfly was difficult, it brought a great improvement in speed. One year later, in 1935, [[Jack Sieg]], a swimmer also from the University of Iowa, developed a kick technique involving swimming on his side and beating his legs in unison, similar to a fish tail, and then modified the technique afterward to swim it face down. He called this style ''Dolphin fishtail kick''.{{citation needed|date=April 2020}} Armbruster and Sieg quickly found that combining these techniques created a very fast swimming style consisting of butterfly arms with two dolphin kicks per cycle.{{citation needed|date=April 2020}} Richard Rhodes claims that Volney Wilson invented the 'Dolphin' after studying fish, and used it to win the 1938 US Olympic Trials, earning him a disqualification.<ref>{{cite book

This new style was substantially faster than a regular breaststroke. Using this technique [[Jack Sieg]] swam 100 yards in 1:00.2.{{citation needed|date=April 2020}} However, the dolphin fishtail kick violated the breaststroke rules set by [[FINA]] and was not allowed. Therefore, the butterfly arms with a breaststroke kick were used by a few swimmers in the [[1936 Summer Olympics]] in [[Berlin]] for the breaststroke competitions.{{citation needed|date=April 2020}} In 1938, almost every breaststroke swimmer was using this butterfly style, yet this stroke was considered a variant of the breaststroke until 1952, when it was accepted by FINA as a separate style with its own set of rules. The [[Swimming at the 1956 Summer Olympics|1956 Summer Olympics]] were the first Olympic games where the butterfly was swum as a separate competition, 100 m (women) and 200 m (men).{{citation needed|date=April 2020}}
==Technique==
The butterfly technique with the dolphin kick consists of synchronous arm movement with a synchronous leg kick.<ref>{{cite news|title=Rhythm of Butterfly Stroke|url=https://news.google.com/newspapers?id=i10hAAAAIBAJ&pg=3094,1585297&dq=butterfly+stroke&hl=en|newspaper=Sarasota Journal|date=August 10, 1966}}</ref> Good technique is crucial to swim this style effectively. The wave-like body movement is also very significant in creating propulsion, as this is the key to easy synchronous over-water recovery and breathing.
In the initial position, the swimmer lies on the breast, the arms are stretched to the front, and the legs are extended to the back.
===Arm movement===
The butterfly stroke has three major parts, the pull, the push, and the recovery. These can also be further subdivided. From the initial position, the arm movement starts very similarly to the breast stroke. At the beginning the hands sink a little bit down with the palms facing outwards and slightly down at shoulder width, then the hands move out to create a Y. This is called catching the water. The pull movement follows a semicircle with the elbow higher than the hand and the hand pointing towards the center of the body and downward to form the traditionally taught "keyhole".
The push pushes the palm backward through the water underneath the body at the beginning and at the side of the body at the end of the push. The swimmer only pushes the arms 1/3 of the way to the hips, making it easier to enter into the recovery and making the recovery shorter and making the breathing window shorter. The movement increases speed throughout the pull-push phase until the hand is the fastest at the end of the push. This step is called the release and is crucial for the recovery. The speed at the end of the push is used to help with the recovery.
In the recovery, the arms are swung sideways across the water surface to the front, with the elbows straight. The arms should be swung forward from the end of the underwater movement; the extension of the triceps in combination with the butterfly kick will allow the arm to be brought forwards quickly in a relaxed manner. In contrast to the [[front crawl]] recovery, the arm recovery is a ballistic shot, letting gravity and momentum do most of the work. The only other way of lifting the arms and the shoulders out of the water would be by dropping one's hips. Therefore, the recovery, at least the acceleration of the arms, is in no way relaxed {{Clarify|date=August 2019}}. It is important not to enter the water too early, because this would generate extra resistance as the arms move forward in the water against the swimming direction, however, during longer distances, this is difficult to avoid, and it is more important to avoid dropping one's hips. A high elbow recovery, as in front crawl, would be disadvantageous because of the natural undulations that are partially caused by the recovery and the relaxed movement caused by the momentum of a triceps extension. Limitations of the shoulder movement in the human body make such a motion unlikely. The hands should enter into the water with a narrow V shape (at 11 and 1 o'clock, if viewed like a clock) with thumbs entering first and pinkies last.
The arms enter the water with the thumbs first at shoulder width. A wider entry loses movement in the next pull phase, and if the hands touch, it will waste energy. The cycle repeats with the pull phase. However, some swimmers prefer to touch in front, because it helps them catch water - as long as they can do this efficiently, they are not losing anything.
===Leg movement===
The legs are synchronized with each other which uses a whole different set of muscles. The shoulders are brought above the surface by a strong up and medium down kick, and back below the surface by a strong down and up kick. A smooth undulation fuses the motion together.
The feet are pressed together to avoid loss of water pressure. The feet are naturally pointing downwards, giving downwards thrust, moving up the feet and pressing down the head.
There is no actual stipulation in competitive butterfly rules that a swimmer make a fixed number of pulses in butterfly–the swimmer may kick as little or as much as he or she may wish.<ref>''See'', for example, [http://www.usaswimming.org/USASWeb/_Rainbow/Documents/9050d5c9-5cd3-4586-8732-f2432351cd21/2006%20Rules%20and%20Regulations%20W-O%20color%20cover.pdf USA Swimming rule 101.2.3] (2006 rules), [http://www.fina.org/rules/SW/rules_sw8.htm FINA rule SW 8.1] {{Webarchive|url=https://web.archive.org/web/20060619044128/http://www.fina.org/rules/SW/rules_sw8.htm |date=2006-06-19 }} (2005-2009 rules)</ref> While competitive rules allow such a choice, the typical method of swimming butterfly is with two kicks.
As butterfly originated as a variant on breaststroke, it would be performed with a breaststroke or whip kick by some swimmers. While breaststroke was separated from butterfly in 1953, the breaststroke kick in butterfly was not officially outlawed until 2001.<ref>[http://www.fina.org/rules/SW/rules_sw8.htm FINA rule SW 8.3] {{Webarchive|url=https://web.archive.org/web/20060619044128/http://www.fina.org/rules/SW/rules_sw8.htm |date=2006-06-19 }} (2005-2009 rules)</ref> However a number of Masters swimmers were upset with the change since they came from a time when butterfly was usually swum with a breaststroke kick.<ref>Showers, Virginia. [http://www.usmsswimmer.com/200503/splashback.pdf "Butterfly's Emergence Challenged 1950s Swimmers"]. USMS Swimmer, page 50. March/April 2005.</ref> FINA was then convinced to allow a breaststroke kick in Masters swimming.<ref>[http://www.fina.org/rules/M/rules_MSW.htm FINA rule MSW 3.10] {{Webarchive|url=https://web.archive.org/web/20060903101658/http://www.fina.org/rules/M/rules_MSW.htm |date=2006-09-03 }} (2005-2009 rules). A similar implementation was made in [http://www.usms.org/rules/part1.pdf USMS rule 101.3.3] (2006 rules).</ref> Given the option, most swimmers choose to use a dolphin kicking action, but there still is a small minority of swimmers who prefer the breaststroke kick, for recreational swimming and even for competition.
===Breathing===
There is only a short window for breathing in the butterfly. If this window is missed, swimming becomes very difficult. Optimally, a butterfly swimmer synchronizes the taking of breaths with the [[Undulatory locomotion|undulation]] of the body to simplify the breathing process; doing this well requires some attention to butterfly stroke technique. The breathing process begins during the underwater "press" portion of the stroke. As the hands and forearms move underneath the chest, the body will naturally rise toward the surface of the water. With minimum effort, the swimmer can lift the head to fully break the surface. The swimmer breathes in through the mouth. The head goes back in the water after the arms come out of the water as they are swinging forward over the surface of the water. If the head stays out too long, the recovery is hindered.
Normally, a breath is taken every other stroke. This can be sustained over long distances. Often, breathing every stroke slows the swimmer down. (At a certain level, a breathing stroke becomes just as fast as a nonbreathing stroke; therefore, very experienced competitors, such as [[Michael Phelps]], may breathe every stroke.) Other intervals of breathing practised by elite swimmers include the "two up, one down" approach in which the swimmer breathes for two successive strokes and then keeps their head in the water on the next stroke, which is easier on the lungs. Swimmers with good lung capacity might also breathe every 3rd stroke during sprints for the finish. Some swimmers can even hold their breaths for an entire race (assuming that it is a short one). To be able to swim with best results it is important to keep one's head down when taking a breath. If the swimmer lifts his or her head too high the swimmer's hips often drop, creating drag, thus slowing the swimmer down. The closer one's head is to the water the better one swims is the general technique used by swimmers.
===Body movement===
Swimming butterfly is difficult if the core is not utilized, and correct timing and body movement makes swimming butterfly much easier. The body moves in a wave-like fashion, controlled by the core, and as the chest is pressed down, the hips go up, and the posterior breaks the water surface and transfers into a fluid kick. During the push phase, the chest goes up and the hips are at their lowest position. In this style, the second pulse in the cycle is stronger than the first pulse, as the second pulse is more in flow with the body movement.
Although butterfly is very compatible with diving, the resulting reduction in wave drag does not lead to an overall reduction of drag. In the modern style of the butterfly stroke one does only little vertical movement of the body.
===Start===
Butterfly uses the regular start for swimming. After the start a gliding phase follows under water, followed by dolphin kicks swim under water. Swimming under water reduces the [[Wave-making resistance|drag from breaking the surface]] and is very economical. Rules allow for 15 m of underwater swimming before the head must break the surface, and regular swimming begins.
===Turn and finish===
During turns and during the finish, both hands must simultaneously touch the wall while the swimmer remains swimming face down. The swimmer touches the wall with both hands while bending the elbows slightly. The bent elbows allow the swimmer to push himself or herself away from the wall and turn sideways. One hand leaves the wall to be moved to the front underwater. At the same time the legs are pulled closer and moved underneath of the body towards the wall. The second hand leaves the wall to be moved to the front over water. It is commonly referred to as an "[[over/under turn]]" or an "[[open turn (swimming)|open turn]]". The legs touch the wall and the hands are at the front. The swimmer sinks under water and lies on the breast, or nearly so. Then the swimmer pushes off the wall, keeping a streamline position with the hands to the front. Similar to the start, the swimmer is allowed to swim 15 m underwater before the head must break the surface. Most swimmers dolphin kick after an initial gliding phase.
The finish requires the swimmer to touch the wall with both hands at the same time, in the same horizontal plane.
===Styles===
There are four styles of butterfly stroke.
Two main styles of butterfly stroke seen today are: "arm pull up simultaneous with dolphin kick" and "arm pull down simultaneous with dolphin kick".<ref>{{cite web|url=https://www.youtube.com/watch?v=8H7u30vnn2g|title=Underwater Comparison Of Butterfly Strokes|last=MscMncVideo|date=28 January 2010|access-date=18 February 2017|via=YouTube}}</ref>
"Arm pull up simultaneous with dolphin kick":
After head goes underwater, both arms go underwater but still higher than head. After first dolphin kick, ''pull both arms immediately with downward motion''. While pulling arms, legs are relaxed, both knees and waist are slightly bent to prepare dolphin kick. After arms push water backward, pull arms up simultaneous with dolphin kick. In this style, turning point from drowning to floating {{clarify|date=October 2019}} is at the time of downward arm motion.
"Arm pull down simultaneous with dolphin kick":
After head goes underwater, both arms go underwater until lower than head. After first dolphin kick, ''raise both arms with relax''. While rising arms, bend both knees and waist to send body back to the surface and prepare dolphin kick. Pull both arms downward while executing dolphin kick. After this sequence, immediately push the water backward. In this style, turning point from drowning to floating is at the time of waist bend.
Two additional styles of butterfly stroke are similar to the two styles above, but without a "second" dolphin kick.<ref>{{cite web|url=https://www.youtube.com/watch?v=EytuMZshGkc|title=YouTube|access-date=18 February 2017}}</ref> This allows the swimmer to conserve energy and be more relaxed.
== FINA butterfly stroke rules ==
SW 8.1 From the beginning of the first arm stroke after the start and each turn, the body shall be kept on the breast. Under water kicking on the side is allowed. It is not permitted to roll onto the back at any time.
SW 8.2 Both arms shall be brought forward together over the water and brought backward simultaneously throughout the race, subject to SW 8.5.
SW 8.3 All up and down movements of the legs must be simultaneous. The legs or the feet need not be on the same level, but they shall not alternate in relation to each other. A breaststroke kicking movement is not permitted.
SW 8.4 At each turn and at the finish of the race, the touch shall be made with both hands simultaneously, at, above or below the water surface.
SW 8.5 At the start and at turns, a swimmer is permitted one or more leg kicks and one arm pull under the water, which must bring him to the surface. It shall be permissible for a swimmer to be completely submerged for a distance of not more than 15 metres after the start and after each turn. By that point, the head must have broken the surface. The swimmer must remain on the surface until the next turn or finish.<ref>{{Cite web |url=http://www.fina.org/H2O/index.php?option=com_content&view=article&id=285:sw-8-butterfly&catid=82:swimming-rules&Itemid=184 |title=FINA Swimming Rules - Butterfly |access-date=2013-05-02 |archive-url=https://web.archive.org/web/20120816004353/http://www.fina.org/H2O/index.php?option=com_content&view=article&id=285:sw-8-butterfly&catid=82:swimming-rules&Itemid=184 |archive-date=2012-08-16 |url-status=dead }}</ref>

The movement increases speed throughout the pull-push phase until the hand is the fastest at the end of the push. This step is called the release and is crucial for the recovery. The speed at the end of the push is used to help with the recovery.
In the recovery, the arms are swung sideways across the water surface to the front, with the elbows straight. The arms should be swung forward from the end of the underwater movement; the extension of the triceps in combination with the butterfly kick will allow the arm to be brought forwards quickly in a relaxed manner. In contrast to the [[front crawl]] recovery, the arm recovery is a ballistic shot, letting gravity and momentum do most of the work. The only other way of lifting the arms and the shoulders out of the water would be by dropping one's hips. Therefore, the recovery, at least the acceleration of the arms, is in no way relaxed {{Clarify|date=August 2019}}. It is important not to enter the water too early, because this would generate extra resistance as the arms move forward in the water against the swimming direction, however, during longer distances, this is difficult to avoid, and it is more important to avoid dropping one's hips. A high elbow recovery, as in front crawl, would be disadvantageous because of the natural undulations that are partially caused by the recovery and the relaxed movement caused by the momentum of a triceps extension. Limitations of the shoulder movement in the human body make such a motion unlikely. The hands should enter into the water with a narrow V shape (at 11 and 1 o'clock, if viewed like a clock) with thumbs entering first and pinkies last.
The arms enter the water with the thumbs first at shoulder width. A wider entry loses movement in the next pull phase, and if the hands touch, it will waste energy. The cycle repeats with the pull phase. However, some swimmers prefer to touch in front, because it helps them catch water - as long as they can do this efficiently, they are not losing anything.
===Leg movement===
The legs are synchronized with each other which uses a whole different set of muscles. The shoulders are brought above the surface by a strong up and medium down kick, and back below the surface by a strong down and up kick. A smooth undulation fuses the motion together.
The feet are pressed together to avoid loss of water pressure. The feet are naturally pointing downwards, giving downwards thrust, moving up the feet and pressing down the head.
There is no actual stipulation in competitive butterfly rules that a swimmer make a fixed number of pulses in butterfly–the swimmer may kick as little or as much as he or she may wish.<ref>''See'', for example, [http://www.usaswimming.org/USASWeb/_Rainbow/Documents/9050d5c9-5cd3-4586-8732-f2432351cd21/2006%20Rules%20and%20Regulations%20W-O%20color%20cover.pdf USA Swimming rule 101.2.3] (2006 rules), [http://www.fina.org/rules/SW/rules_sw8.htm FINA rule SW 8.1] {{Webarchive|url=https://web.archive.org/web/20060619044128/http://www.fina.org/rules/SW/rules_sw8.htm |date=2006-06-19 }} (2005-2009 rules)</ref> While competitive rules allow such a choice, the typical method of swimming butterfly is with two kicks.
As butterfly originated as a variant on breaststroke, it would be performed with a breaststroke or whip kick by some swimmers. While breaststroke was separated from butterfly in 1953, the breaststroke kick in butterfly was not officially outlawed until 2001.<ref>[http://www.fina.org/rules/SW/rules_sw8.htm FINA rule SW 8.3] {{Webarchive|url=https://web.archive.org/web/20060619044128/http://www.fina.org/rules/SW/rules_sw8.htm |date=2006-06-19 }} (2005-2009 rules)</ref> However a number of Masters swimmers were upset with the change since they came from a time when butterfly was usually swum with a breaststroke kick.<ref>Showers, Virginia. [http://www.usmsswimmer.com/200503/splashback.pdf "Butterfly's Emergence Challenged 1950s Swimmers"]. USMS Swimmer, page 50. March/April 2005.</ref> FINA was then convinced to allow a breaststroke kick in Masters swimming.<ref>[http://www.fina.org/rules/M/rules_MSW.htm FINA rule MSW 3.10] {{Webarchive|url=https://web.archive.org/web/20060903101658/http://www.fina.org/rules/M/rules_MSW.htm |date=2006-09-03 }} (2005-2009 rules). A similar implementation was made in [http://www.usms.org/rules/part1.pdf USMS rule 101.3.3] (2006 rules).</ref> Given the option, most swimmers choose to use a dolphin kicking action, but there still is a small minority of swimmers who prefer the breaststroke kick, for recreational swimming and even for competition.
===Breathing===
There is only a short window for breathing in the butterfly. If this window is missed, swimming becomes very difficult. Optimally, a butterfly swimmer synchronizes the taking of breaths with the [[Undulatory locomotion|undulation]] of the body to simplify the breathing process; doing this well requires some attention to butterfly stroke technique. The breathing process begins during the underwater "press" portion of the stroke. As the hands and forearms move underneath the chest, the body will naturally rise toward the surface of the water. With minimum effort, the swimmer can lift the head to fully break the surface. The swimmer breathes in through the mouth. The head goes back in the water after the arms come out of the water as they are swinging forward over the surface of the water. If the head stays out too long, the recovery is hindered.
Normally, a breath is taken every other stroke. This can be sustained over long distances. Often, breathing every stroke slows the swimmer down. (At a certain level, a breathing stroke becomes just as fast as a nonbreathing stroke; therefore, very experienced competitors, such as [[Michael Phelps]], may breathe every stroke.) Other intervals of breathing practised by elite swimmers include the "two up, one down" approach in which the swimmer breathes for two successive strokes and then keeps their head in the water on the next stroke, which is easier on the lungs. Swimmers with good lung capacity might also breathe every 3rd stroke during sprints for the finish. Some swimmers can even hold their breaths for an entire race (assuming that it is a short one). To be able to swim with best results it is important to keep one's head down when taking a breath. If the swimmer lifts his or her head too high the swimmer's hips often drop, creating drag, thus slowing the swimmer down. The closer one's head is to the water the better one swims is the general technique used by swimmers.
===Body movement===
Swimming butterfly is difficult if the core is not utilized, and correct timing and body movement makes swimming butterfly much easier. The body moves in a wave-like fashion, controlled by the core, and as the chest is pressed down, the hips go up, and the posterior breaks the water surface and transfers into a fluid kick. During the push phase, the chest goes up and the hips are at their lowest position. In this style, the second pulse in the cycle is stronger than the first pulse, as the second pulse is more in flow with the body movement.
Although butterfly is very compatible with diving, the resulting reduction in wave drag does not lead to an overall reduction of drag. In the modern style of the butterfly stroke one does only little vertical movement of the body.
===Start===
Butterfly uses the regular start for swimming. After the start a gliding phase follows under water, followed by dolphin kicks swim under water. Swimming under water reduces the [[Wave-making resistance|drag from breaking the surface]] and is very economical. Rules allow for 15 m of underwater swimming before the head must break the surface, and regular swimming begins.
===Turn and finish===
During turns and during the finish, both hands must simultaneously touch the wall while the swimmer remains swimming face down. The swimmer touches the wall with both hands while bending the elbows slightly. The bent elbows allow the swimmer to push himself or herself away from the wall and turn sideways. One hand leaves the wall to be moved to the front underwater. At the same time the legs are pulled closer and moved underneath of the body towards the wall. The second hand leaves the wall to be moved to the front over water. It is commonly referred to as an "[[over/under turn]]" or an "[[open turn (swimming)|open turn]]". The legs touch the wall and the hands are at the front. The swimmer sinks under water and lies on the breast, or nearly so. Then the swimmer pushes off the wall, keeping a streamline position with the hands to the front. Similar to the start, the swimmer is allowed to swim 15 m underwater before the head must break the surface. Most swimmers dolphin kick after an initial gliding phase.
The finish requires the swimmer to touch the wall with both hands at the same time, in the same horizontal plane.
===Styles===
There are four styles of butterfly stroke.
Two main styles of butterfly stroke seen today are: "arm pull up simultaneous with dolphin kick" and "arm pull down simultaneous with dolphin kick".<ref>{{cite web|url=https://www.youtube.com/watch?v=8H7u30vnn2g|title=Underwater Comparison Of Butterfly Strokes|last=MscMncVideo|date=28 January 2010|access-date=18 February 2017|via=YouTube}}</ref>
"Arm pull up simultaneous with dolphin kick":
After head goes underwater, both arms go underwater but still higher than head. After first dolphin kick, ''pull both arms immediately with downward motion''. While pulling arms, legs are relaxed, both knees and waist are slightly bent to prepare dolphin kick. After arms push water backward, pull arms up simultaneous with dolphin kick. In this style, turning point from drowning to floating {{clarify|date=October 2019}} is at the time of downward arm motion.
"Arm pull down simultaneous with dolphin kick":
After head goes underwater, both arms go underwater until lower than head. After first dolphin kick, ''raise both arms with relax''. While rising arms, bend both knees and waist to send body back to the surface and prepare dolphin kick. Pull both arms downward while executing dolphin kick. After this sequence, immediately push the water backward. In this style, turning point from drowning to floating is at the time of waist bend.
Two additional styles of butterfly stroke are similar to the two styles above, but without a "second" dolphin kick.<ref>{{cite web|url=https://www.youtube.com/watch?v=EytuMZshGkc|title=YouTube|access-date=18 February 2017}}</ref> This allows the swimmer to conserve energy and be more relaxed.
== FINA butterfly stroke rules ==
SW 8.1 From the beginning of the first arm stroke after the start and each turn, the body shall be kept on the breast. Under water kicking on the side is allowed. It is not permitted to roll onto the back at any time.
SW 8.2 Both arms shall be brought forward together over the water and brought backward simultaneously throughout the race, subject to SW 8.5.
SW 8.3 All up and down movements of the legs must be simultaneous. The legs or the feet need not be on the same level, but they shall not alternate in relation to each other. A breaststroke kicking movement is not permitted.
SW 8.4 At each turn and at the finish of the race, the touch shall be made with both hands simultaneously, at, above or below the water surface.
SW 8.5 At the start and at turns, a swimmer is permitted one or more leg kicks and one arm pull under the water, which must bring him to the surface. It shall be permissible for a swimmer to be completely submerged for a distance of not more than 15 metres after the start and after each turn. By that point, the head must have broken the surface. The swimmer must remain on the surface until the next turn or finish.<ref>{{Cite web |url=http://www.fina.org/H2O/index.php?option=com_content&view=article&id=285:sw-8-butterfly&catid=82:swimming-rules&Itemid=184 |title=FINA Swimming Rules - Butterfly |access-date=2013-05-02 |archive-url=https://web.archive.org/web/20120816004353/http://www.fina.org/H2O/index.php?option=com_content&view=article&id=285:sw-8-butterfly&catid=82:swimming-rules&Itemid=184 |archive-date=2012-08-16 |url-status=dead }}</ref>

While other styles like the [[breaststroke]], [[front crawl]], or [[backstroke]] can be swum adequately by beginners, the butterfly is a more difficult stroke that requires good technique as well as strong muscles.

-==Speed and ergonomics==
-The peak speed of the butterfly is faster than that of the front crawl due to the synchronous pull/push with both arms and legs, which is done quickly. Yet since speed drops significantly during the recovery phase, it is overall slightly slower than front crawl, especially over longer distances. Another reason it is slower is because of the extremely different physical exertion it puts on the swimmer compared to the front crawl.

-The breaststroke, backstroke, and front crawl can all be swum easily even if the swimmer's technique is not the best. The butterfly, however, is unforgiving of mistakes in style; it is very difficult to overcome a poor butterfly technique with brute strength. Many swimmers and coaches consider it the most difficult swimming style. The main difficulty for beginners is the synchronous over-water recovery, especially when combined with breathing, since both arms, the head, shoulders, and part of the chest have to be lifted out of the water for these tasks. Once the efficient technique has been developed, it becomes a smooth, fast stroke.<ref>{{cite web|url=https://www.youtube.com/watch?v=R-639WuN-b0|title=YouTube|access-date=18 February 2017}}</ref>

Cavill (1881–1945), the son of "swimming professor" <a href="/enwiki/wiki/Cavill_family" title="Cavill family">Frederick Cavill</a>, was 220 yards amateur champion of Australia at the age of 16.

</p><p>In late 1933, Henry Myers swam a butterfly stroke in competition at the Brooklyn Central YMCA.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4">[4]</a></sup> The butterfly style evolved from the breaststroke. David Armbruster, swimming coach at the <a href="/enwiki/wiki/University_of_Iowa" title="University of Iowa">University of Iowa</a>, researched the breaststroke, especially considering the problem of drag due to the underwater recovery. In 1934 Armbruster refined a method to bring the arms forward over the water in a breaststroke. He called this style "butterfly".<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/enwiki/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

One year later, in 1935, <a href="/enwiki/wiki/Jack_Sieg" title="Jack Sieg">Jack Sieg</a>, a swimmer also from the University of Iowa, developed a kick technique involving swimming on his side and beating his legs in unison, similar to a fish tail, and then modified the technique afterward to swim it face down. He called this style <i>Dolphin fishtail kick</i>.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/enwiki/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

</p><p>This new style was substantially faster than a regular breaststroke.

Therefore, the butterfly arms with a breaststroke kick were used by a few swimmers in the <a href="/enwiki/wiki/1936_Summer_Olympics" title="1936 Summer Olympics">1936 Summer Olympics</a> in <a href="/enwiki/wiki/Berlin" title="Berlin">Berlin</a> for the breaststroke competitions.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/enwiki/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

The <a href="/enwiki/wiki/Swimming_at_the_1956_Summer_Olympics" title="Swimming at the 1956 Summer Olympics">1956 Summer Olympics</a> were the first Olympic games where the butterfly was swum as a separate competition, 100 m (women) and 200 m (men).<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/enwiki/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

<p>The butterfly technique with the dolphin kick consists of synchronous arm movement with a synchronous leg kick.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6">[6]</a></sup> Good technique is crucial to swim this style effectively. The wave-like body movement is also very significant in creating propulsion, as this is the key to easy synchronous over-water recovery and breathing.
</p><p>In the initial position, the swimmer lies on the breast, the arms are stretched to the front, and the legs are extended to the back.
</p>
<h3><span class="mw-headline" id="Arm_movement">Arm movement</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/enwiki/w/index.php?title=Butterfly_stroke&action=edit&section=3" title="Edit section: Arm movement">edit</a><span class="mw-editsection-bracket">]</span></span></h3>
<p>The butterfly stroke has three major parts, the pull, the push, and the recovery. These can also be further subdivided. From the initial position, the arm movement starts very similarly to the breast stroke. At the beginning the hands sink a little bit down with the palms facing outwards and slightly down at shoulder width, then the hands move out to create a Y. This is called catching the water. The pull movement follows a semicircle with the elbow higher than the hand and the hand pointing towards the center of the body and downward to form the traditionally taught "keyhole".
</p><p>The push pushes the palm backward through the water underneath the body at the beginning and at the side of the body at the end of the push. The swimmer only pushes the arms 1/3 of the way to the hips, making it easier to enter into the recovery and making the recovery shorter and making the breathing window shorter. The movement increases speed throughout the pull-push phase until the hand is the fastest at the end of the push. This step is called the release and is crucial for the recovery. The speed at the end of the push is used to help with the recovery.
</p><p>In the recovery, the arms are swung sideways across the water surface to the front, with the elbows straight. The arms should be swung forward from the end of the underwater movement; the extension of the triceps in combination with the butterfly kick will allow the arm to be brought forwards quickly in a relaxed manner. In contrast to the <a href="/enwiki/wiki/Front_crawl" title="Front crawl">front crawl</a> recovery, the arm recovery is a ballistic shot, letting gravity and momentum do most of the work. The only other way of lifting the arms and the shoulders out of the water would be by dropping one's hips. Therefore, the recovery, at least the acceleration of the arms, is in no way relaxed<sup class="noprint Inline-Template" style="margin-left:0.1em; white-space:nowrap;">[<i><a href="/enwiki/wiki/Wikipedia:Please_clarify" title="Wikipedia:Please clarify"><span title="The text near this tag may need clarification or removal of jargon. (August 2019)">clarification needed</span></a></i>]</sup>. It is important not to enter the water too early, because this would generate extra resistance as the arms move forward in the water against the swimming direction, however, during longer distances, this is difficult to avoid, and it is more important to avoid dropping one's hips. A high elbow recovery, as in front crawl, would be disadvantageous because of the natural undulations that are partially caused by the recovery and the relaxed movement caused by the momentum of a triceps extension. Limitations of the shoulder movement in the human body make such a motion unlikely. The hands should enter into the water with a narrow V shape (at 11 and 1 o'clock, if viewed like a clock) with thumbs entering first and pinkies last.
</p><p>The arms enter the water with the thumbs first at shoulder width. A wider entry loses movement in the next pull phase, and if the hands touch, it will waste energy. The cycle repeats with the pull phase. However, some swimmers prefer to touch in front, because it helps them catch water - as long as they can do this efficiently, they are not losing anything.
</p>
<h3><span class="mw-headline" id="Leg_movement">Leg movement</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/enwiki/w/index.php?title=Butterfly_stroke&action=edit&section=4" title="Edit section: Leg movement">edit</a><span class="mw-editsection-bracket">]</span></span></h3>
<p>The legs are synchronized with each other which uses a whole different set of muscles. The shoulders are brought above the surface by a strong up and medium down kick, and back below the surface by a strong down and up kick. A smooth undulation fuses the motion together.
</p><p>The feet are pressed together to avoid loss of water pressure. The feet are naturally pointing downwards, giving downwards thrust, moving up the feet and pressing down the head.
</p><p>There is no actual stipulation in competitive butterfly rules that a swimmer make a fixed number of pulses in butterfly–the swimmer may kick as little or as much as he or she may wish.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7">[7]</a></sup> While competitive rules allow such a choice, the typical method of swimming butterfly is with two kicks.
</p><p>As butterfly originated as a variant on breaststroke, it would be performed with a breaststroke or whip kick by some swimmers. While breaststroke was separated from butterfly in 1953, the breaststroke kick in butterfly was not officially outlawed until 2001.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8">[8]</a></sup> However a number of Masters swimmers were upset with the change since they came from a time when butterfly was usually swum with a breaststroke kick.<sup id="cite_ref-9" class="reference"><a href="#cite_note-9">[9]</a></sup> FINA was then convinced to allow a breaststroke kick in Masters swimming.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10">[10]</a></sup> Given the option, most swimmers choose to use a dolphin kicking action, but there still is a small minority of swimmers who prefer the breaststroke kick, for recreational swimming and even for competition.

<h3><span class="mw-headline" id="Breathing">Breathing</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/enwiki/w/index.php?title=Butterfly_stroke&action=edit&section=5" title="Edit section: Breathing">edit</a><span class="mw-editsection-bracket">]</span></span></h3>
<p>There is only a short window for breathing in the butterfly. If this window is missed, swimming becomes very difficult. Optimally, a butterfly swimmer synchronizes the taking of breaths with the <a href="/enwiki/wiki/Undulatory_locomotion" title="Undulatory locomotion">undulation</a> of the body to simplify the breathing process; doing this well requires some attention to butterfly stroke technique. The breathing process begins during the underwater "press" portion of the stroke. As the hands and forearms move underneath the chest, the body will naturally rise toward the surface of the water. With minimum effort, the swimmer can lift the head to fully break the surface. The swimmer breathes in through the mouth. The head goes back in the water after the arms come out of the water as they are swinging forward over the surface of the water. If the head stays out too long, the recovery is hindered.
</p><p>Normally, a breath is taken every other stroke. This can be sustained over long distances. Often, breathing every stroke slows the swimmer down. (At a certain level, a breathing stroke becomes just as fast as a nonbreathing stroke; therefore, very experienced competitors, such as <a href="/enwiki/wiki/Michael_Phelps" title="Michael Phelps">Michael Phelps</a>, may breathe every stroke.) Other intervals of breathing practised by elite swimmers include the "two up, one down" approach in which the swimmer breathes for two successive strokes and then keeps their head in the water on the next stroke, which is easier on the lungs. Swimmers with good lung capacity might also breathe every 3rd stroke during sprints for the finish. Some swimmers can even hold their breaths for an entire race (assuming that it is a short one). To be able to swim with best results it is important to keep one's head down when taking a breath. If the swimmer lifts his or her head too high the swimmer's hips often drop, creating drag, thus slowing the swimmer down. The closer one's head is to the water the better one swims is the general technique used by swimmers.

<p>Swimming butterfly is difficult if the core is not utilized, and correct timing and body movement makes swimming butterfly much easier. The body moves in a wave-like fashion, controlled by the core, and as the chest is pressed down, the hips go up, and the posterior breaks the water surface and transfers into a fluid kick. During the push phase, the chest goes up and the hips are at their lowest position. In this style, the second pulse in the cycle is stronger than the first pulse, as the second pulse is more in flow with the body movement.
</p><p>Although butterfly is very compatible with diving, the resulting reduction in wave drag does not lead to an overall reduction of drag. In the modern style of the butterfly stroke one does only little vertical movement of the body.

<p>Butterfly uses the regular start for swimming. After the start a gliding phase follows under water, followed by dolphin kicks swim under water. Swimming under water reduces the <a href="/enwiki/wiki/Wave-making_resistance" title="Wave-making resistance">drag from breaking the surface</a> and is very economical. Rules allow for 15 m of underwater swimming before the head must break the surface, and regular swimming begins.

<p>During turns and during the finish, both hands must simultaneously touch the wall while the swimmer remains swimming face down. The swimmer touches the wall with both hands while bending the elbows slightly. The bent elbows allow the swimmer to push himself or herself away from the wall and turn sideways. One hand leaves the wall to be moved to the front underwater. At the same time the legs are pulled closer and moved underneath of the body towards the wall. The second hand leaves the wall to be moved to the front over water. It is commonly referred to as an "<a href="/enwiki/wiki/Over/under_turn" class="mw-redirect" title="Over/under turn">over/under turn</a>" or an "<a href="/enwiki/wiki/Open_turn_(swimming)" class="mw-redirect" title="Open turn (swimming)">open turn</a>". The legs touch the wall and the hands are at the front. The swimmer sinks under water and lies on the breast, or nearly so. Then the swimmer pushes off the wall, keeping a streamline position with the hands to the front. Similar to the start, the swimmer is allowed to swim 15 m underwater before the head must break the surface. Most swimmers dolphin kick after an initial gliding phase.
</p><p>The finish requires the swimmer to touch the wall with both hands at the same time, in the same horizontal plane.

</p><p>"Arm pull down simultaneous with dolphin kick":
After head goes underwater, both arms go underwater until lower than head. After first dolphin kick, <i>raise both arms with relax</i>. While rising arms, bend both knees and waist to send body back to the surface and prepare dolphin kick. Pull both arms downward while executing dolphin kick. After this sequence, immediately push the water backward. In this style, turning point from drowning to floating is at the time of waist bend.
</p><p>Two additional styles of butterfly stroke are similar to the two styles above, but without a "second" dolphin kick.<sup id="cite_ref-12" class="reference"><a href="#cite_note-12">[12]</a></sup> This allows the swimmer to conserve energy and be more relaxed.

<p>SW 8.1 From the beginning of the first arm stroke after the start and each turn, the body shall be kept on the breast. Under water kicking on the side is allowed. It is not permitted to roll onto the back at any time.
</p><p>SW 8.2 Both arms shall be brought forward together over the water and brought backward simultaneously throughout the race, subject to SW 8.5.
</p><p>SW 8.3 All up and down movements of the legs must be simultaneous. The legs or the feet need not be on the same level, but they shall not alternate in relation to each other. A breaststroke kicking movement is not permitted.
</p><p>SW 8.4 At each turn and at the finish of the race, the touch shall be made with both hands simultaneously, at, above or below the water surface.
</p><p>SW 8.5 At the start and at turns, a swimmer is permitted one or more leg kicks and one arm pull under the water, which must bring him to the surface. It shall be permissible for a swimmer to be completely submerged for a distance of not more than 15 metres after the start and after each turn. By that point, the head must have broken the surface. The swimmer must remain on the surface until the next turn or finish.<sup id="cite_ref-13" class="reference"><a href="#cite_note-13">[13]</a></sup>
