The first indoor swimming pool was built in England in 1862. An Amateur Swimming Association of Great Britain was organized in 1880 with more than 300 members. The main swimming styles were the breaststroke and the recently developed side stroke. In the sidestroke, the swimmer lies on one side. Initially, the arms were brought forward under water, but this was soon modified to bring the arm forward over water to reduce resistance and to improve the speed, resulting in an overarm sidestroke. The legs were squeezed together in a scissor style. In 1895, J. H. Thayers of England swam 100 yards (91.4 m) in a record-breaking 1:02.50 using a sidestroke.

Sometime between 1870 and 1890 (the date is most often given as 1873), John Arthur Trudgen reintroduced the front crawl to England, having learned the stroke from Native Americans during a trip to South America

. His stroke, a variant of the front crawl, came to be called the Trudgen or Trudgeon. The arms were brought forward, alternating, while the body rolled from side to side. The kick was a scissors kick such as that familiarly used in breaststroke, with one kick for two arm strokes, although it is believed that the Native Americans had indeed used a flutter kick. Front crawl variants used different ratios of scissor kicks to arm strokes, or alternated with a flutter (up-and-down) kick. The speed of the new stroke was demonstrated by F.V.C. Lane in 1901, swimming 100 yards (91.4 m) in 1:00.0, an improvement of about ten seconds compared to the breaststroke record. This style is the first European version of the front crawl, the fastest swimming style known today. Due to its speed the Trudgen became very quickly popular around the world, despite all the ungentlemanlike splashing.

The Trudgen was improved by Australian-born Richmond Cavill (born Sydney 1884). Cavill, whose father Frederick Cavill narrowly failed to swim the English Channel, is credited with developing the stroke by observing a young boy from the Solomon Island, Alick Wickham. Cavill and his brothers (Sydney, Charles, Arthur, Ernest and Percy) were all champion swimmers and formed arguably the greatest swimming dynasty. They spread the Australian crawl to England, New Zealand and America. Richmond - or Dick as he was better known - used this stroke in 1902 at an International Championships in England to set a new world record by out swimming all Trudgen swimmers over the 100 yards (91.4 m) in 0:58.4

. Armbruster also researched a problem of breaststroke where the swimmer was slowed down significantly while bringing the arms forward underwater. In 1934 Armbruster refined a method to bring the arms forward over water in breaststroke. While this "butterfly" technique was difficult, it brought a great improvement in speed. One year later, in 1935, Jack Sieg

 developed a technique involving swimming on his side and beating his legs in unison similar to a fish tail, and modified the technique afterward to swim it face down. Armbruster and Sieg combined these techniques into a variant of the breaststroke called butterfly with the two kicks per cycle being called dolphin fishtail kick. Using this technique Sieg swam 100 yards (91.4 m) in 1:00.2. However, even though this technique was much faster than regular breaststroke, the dolphin fishtail kick violated the rules and was not allowed. Therefore, the butterfly arms with a breaststroke kick were used by a few swimmers in the 1936 Summer Olympics

The 1936 Summer Olympics, officially known as the Games of the XI Olympiad, was an international multi-sport event which was held in 1936 in Berlin, Germany. Berlin won the bid to host the Games over Barcelona, Spain on April 26, 1931, at the 29th IOC Session in Barcelona...

 in Berlin for the breaststroke competitions. 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 as a separate style with a set of rules.

Around that time another modification to the backstroke became popular. Previously, the arms were held straight during the underwater push phase, for example by the top backstroke swimmer from 1935 to 1945, Adolph Kiefer

Adolph Gustav "Sonny Boy" Kiefer was an American swimmer and the first man in the world to swim 100 yards backstroke under 1 minute. His backstroke records stood for 15 years...

. However, Australian swimmers developed a technique where the arms are bent under water, increasing the horizontal push and the resulting speed and reducing the wasted force upward and sideways. This style is now generally used worldwide. In 1935 topless swimsuits for men were worn for the first time during an official competition.

In 1943 the US ordered the reduction of fabric in swimsuits by 10% due to wartime shortages, resulting in the first two piece swimsuits. Shortly afterwards the Bikini

Another modification was developed for breaststroke. In breaststroke, breaking the water surface increases the friction, reducing the speed of the swimmer. Therefore, swimming underwater increases the speed. This led to a controversy at the 1956 Summer Olympics

, circumvented the rule by not surfacing at all after the start, but swimming as much of the lane under water as possible before breaking the surface. He swam all but 5 m under water for the first three 50 m laps, and also swam half under water for the last lap, winning the gold medal. The adoption of this technique led to many swimmers suffering from oxygen starvation or even some swimmers passing out during the race due to a lack of air, and a new breaststroke rule was introduced by the FINA, additionally limiting the distance that can be swum under water after the start and every turn, and requiring the head to break the surface every cycle. The 1956 Games in Melbourne also saw the introduction of the flip turn, a sort of tumble turn

. Berkoff swam 33 m of the first lane completely underwater using only a dolphin kick, far ahead of his competition. A sports commentator called this a Berkoff Blastoff. Suzuki, having practiced the underwater technique for 10 years, surfaced only a little bit earlier, winning the race in 55.05. At that time, this was not restricted by FINA backstroke rules. The backstroke rules were quickly changed in the same year by the FINA to ensure the health and safety of the swimmers, limiting the underwater phase after the start to ten meters, which was expanded to 15 m in 1991. In Seoul, Kristin Otto

 from East Germany won six gold medals, the most ever won by a woman.

Another innovation is the use of flip turns for backstroke. According to the rules, a backstroke swimmer had to touch the wall while lying less than 90 degree
Degree (angle)
A degree , usually denoted by ° , is a measurement of plane angle, representing 1⁄360 of a full rotation; one degree is equivalent to π/180 radians...

s out of the horizontal. Some swimmers discovered that they could turn faster if they rolled almost 90 degrees sideways, touched the wall, and made a forward tumble turn, pushing off the wall on their backs. The FINA has changed the rules to allow the swimmers to turn over completely before touching the wall to simplify this turn and to improve the speed of the races.

Similarly, the dolphin-kick underwater swimming technique is now also used for butterfly. Consequently, in 1998 FINA introduced a rule limiting swimmers to 15 meters underwater per lap before they must surface. After underwater swimming for freestyle and backstroke, the underwater swimming technique is now also used for butterfly, for example by Denis Pankratov

It is faster to do butterfly kick underwater for the first few meters off the wall than swimming at the surface. In 2005, FINA declared that you may take 1 underwater dolphin kick in the motion of a breaststroke pull-out.
