Congratulations to the Chinese team for winning the silver medal in the butterfly stroke.

Come on for the Chinese team!

On the morning of July 26, in the women’s 100-meter butterfly swimming competition at the Tokyo Olympics, Chinese athlete Zhang Yufei won a silver medal with a time of 55.64 seconds! This is also the first medal won by the Chinese swimming team in this Olympic Games. congratulate!

Among the four mainstream swimming styles of butterfly, backstroke, breaststroke and freestyle, butterfly is the latest one to appear. The butterfly stroke ranks in the forefront of various swimming styles in terms of difficulty and physical exertion. So why is butterfly swimming still loved by many people and even become an Olympic event?

The history of human swimming may be as long as the history of human beings. Through the ancient cave paintings, we can know that since at least the Stone Age, humans have learned the skill of swimming in order to cross rivers and lakes as a way to pass, exercise or entertain.

When it comes to swimming, the first question is what posture to use. Standing by the edge of any swimming pool, you can see a variety of postures. There are dog planing, breaststroke, freestyle, and others simply paddling without knowing the stroke. Since swimming has been developed for so long, why are there only four mainstream styles of butterfly, backstroke, breaststroke, and freestyle? Where did the other positions go?

Learning from animals-early breaststroke dominating the swimming pool

The earliest swimming styles learned by humans are believed to be dog paddles obtained by observing dogs swimming. While lying flat in the water, the head is above the water, and the limbs are used to go forward in the water, but this posture is slower.

Later, by observing the frog’s swimming posture, humans learned a similar breaststroke (Breaststroke) swimming style. Like the dog-climbing style, they were lying flat in the water, imitating the frog’s forelimb rowing and hind limb kicking. Out of the water.

The breaststroke has been thriving for a while. Swimming began to become popular as a sport and entertainment around the beginning of the 19th century. In the early days, people had a variety of swimming styles, but most European competitive swimming competitions used breaststroke. Because breaststroke is faster than dog planing and saves effort, it is suitable for long-distance swimming. For example, the first man to navigate Ying Jili Strait people, breaststroke is used. Although breaststroke is the slowest of the four modern swimming styles, it has a low threshold and is easy to learn. Therefore, in China, breaststroke has become the first swimming style to be trained in many amateur swimming training classes.

Later, some people swim breaststroke by lying on their back, so that the nose and mouth are always above the water to facilitate breathing. This pose is called inverted breaststroke (Inverted breaststroke). This is also the posture used in the early backstroke.

 Speaking of swimming, you have to learn to climb first 

Around 1873, the British swimmer, Trajan, used the posture of the natives of South America to extend their arms alternately, combined with the kicking action of the breaststroke, to improve the swimming style, known as the Trajan. Later, this kind of swimming style was developed to retain the upper body movement, while the lower body was changed to the movement of alternately kicking the water with the legs. People began to call this brand new swimming style the front crawl. At the same time, like breaststroke, the posture of crawling while lying on your back also appeared, which was later called Back crawl or Backstroke.

However, whether it is crawl or reverse crawl, the effective thrust generated by the longer stroke of the arm stroke is greater, and the posture is closer to the streamline and the relative resistance is lower, so it is faster than the previously commonly used breaststroke and reverse breaststroke. Therefore, crawl swimming gradually became popular in the pursuit of higher and faster competitive sports.

Modern swimming, can you freestyle?

Around the beginning of the 19th century, swimming started to develop as we know it today. The world’s first swimming association was established in London in 1837. At that time, there were six man-made indoor swimming pools in London. The world’s first swimming championship was held in Australia in 1846. The event was a 400-meter swimming, which later developed into an annual event. In the United States, swimming gradually became popular in the 1880s. With the establishment of the Amateur Athletic Association (AAU) in 1888, more than 300 swimming clubs appeared nationwide.

After entering the Olympic Games, swimming became an official event at the first modern Olympic Games (1896). At first, swimming competitions did not stipulate specific postures, but were freely chosen by athletes. Therefore, it is called Freestyle and can be used. Any posture such as crawl, breaststroke, dog-climbing, sidestroke, etc., or even compose a set of strokes. Of course, more people use the fastest crawl. Therefore, in the freestyle event, people mainly adopt the crawl style in order to achieve the best results. To this day, the freestyle event still does not specify a specific stroke, but because crawling is commonly used, when it comes to freestyle, it actually refers to crawling.

Then the backstroke entered the Olympics in 1900, and the breaststroke became a separate event at the 1904 Olympics. After that, in 1909, the International Swimming Federation (FINA) was established, headquartered in Lausanne, Switzerland. Competitive swimming has entered a new era. In the following days, FINA has formulated and improved the rules of various swimming events, unified the track system of international competitions and standardized swimming styles.

Butterfly, gifted the United States at the expense of ……

The butterfly stroke is the latest stroke to appear. Around the 1930s, some athletes at that time discovered that changing the underwater arm movement during breaststroke to enter the water with both hands over the top of the head at the same time can make swimming faster (this kind of movement was quickly banned in the water). Used in breaststroke). Later, someone imitated the dolphin’s wave-like swing, so the leg movements were also improved, so the last swimming style we know-the butterfly stroke (Butterfly stroke) appeared.

Butterfly stroke also has obvious shortcomings. First of all, it is very difficult to learn. It requires the core area to be stable, and the hands, feet and even the whole body are highly coordinated, which is difficult to master compared to other swimming styles. Secondly, its physical exertion is also the largest among various swimming styles, which is not suitable for long-distance use. Finally, in addition to the technical difficulty of learning, it swims relatively quietly, with waves flying and splashing. Especially in the beginner’s stage, it is easy to cause a lot of attention .

However, in terms of speed, the butterfly stroke is second only to crawl stroke. In particular, it is not only faster, but also charming and beautiful movement, also attracted a lot of swim swimmer to use it. In 1956, the butterfly officially became the last stroke to join the Olympic family.

The four major swimming styles have their own origins. For ordinary people, they can choose according to their physical conditions and personal preferences. Finally, swimming safety is always the first. No matter what swimming style you learn, the most important life skills in swimming, such as treading on the water, choking on the water, self-rescue by choking, holding your breath, floating calmly, waiting for rescue, etc. are probably the most important life skills in swimming.
