What are the advantages of each of the four strokes

1. The oldest stroke: breaststroke.

Breaststroke is a swimming posture that imitates the swimming movement of frogs, and it is also the oldest swimming stroke. When breaststroke is performed, swimmers can easily observe whether there are obstacles in front of them, and avoid hitting the obstacles.

In the mid-18th century, breaststroke was known as "green frog swimming" in Europe. Because of its slower speed, breaststroke was not as fast as other strokes in freestyle competitions (free swimming without prescribed strokes) in the early 1900s, which sidelined the breaststroke technique. The breaststroke technique was sidelined when FINA prescribed the strokes. Breaststroke is one of the competitive swimming strokes.

The human body lies prone on the surface of the water, the two arms in front of the chest symmetrical straight arm side downward flexion paddling, the two legs symmetrical flexion and extension stirrups clamping the water, like a frog swimming. Breaststroke is more labor-saving, easy to last, commonly used in fishing and hunting, swimming, rescue, water handling.

2. Fastest stroke: freestyle.

Freestyle is one of the competitive swimming events. There is no restriction on the technique, and athletes often use the fastest crawl technique, which makes people call the crawl freestyle.

At the beginning of the 19th century, Australian R. Carvell used two legs to beat water alternately, replacing the clipper technique to win the race, and in 1922, American Wes Morrow improved the technique by using two arms to stroke alternately and two legs to beat water alternately six times, forming the modern crawling swimming mode.

1896 the first Olympic Games freestyle was listed as an official competition program, freestyle is not subject to any posture restrictions, crawl swimming is the fastest, and is currently the only freestyle posture, this posture is structurally sound, resistance is small, the speed is uniform, and it is the most energy-saving a useful posture.

3. The most energy-saving stroke: backstroke.

Backstroke is a swimming position in which the human body lies on its back in the water. There is a long history of backstroke technique, and there was a record of backstroke technique in 1794, but until the early 19th century, backstroke still used two arms to stroke backward at the same time, and two legs to do breaststroke strokes, that is, the current "anti-breaststroke".

Since the emergence of crawling technique in 1902, due to the reasonable technique and fast speed of crawling, some people began to adopt the swimming method of backward stroking of both arms in turn, which is similar to crawling. However, it was not until 1921 that the current backstroke technique was initially developed. The backstroke technique is easy to breathe because the head is exposed to the water; lying on the water, it is more energy-saving.

4. The best looking stroke: butterfly.

The butterfly technique evolved from the breaststroke technique movements. When the breaststroke technique developed to the second stage, that is, in the period of 1937-1952, in the swimming competition, some athletes used two arms to stroke to the thighs and then raised the water surface, and then migrated from the air, from the appearance, it looks like a butterfly spreading its wings and fluttering, so people call it "butterfly swimming".

Butterfly swimming is the last of the four competitive swimming strokes to be developed. It is also called "dolphin swim" because its leg movements resemble those of a dolphin.

Swimming (Swimming?) is a skill in which a person floats upward under the buoyant force of water, and the body moves regularly through the regular movement of the limbs by virtue of the buoyant force.

Swimming can be divided into competitive swimming and practical swimming. Competitive swimming is the second largest event in the Olympic Games, which includes four strokes of butterfly, backstroke (also known as backstroke), breaststroke, and jogging (also known as crawl/freestyle), as well as synchronized swimming.

With the development of swimming, swimming is divided into two categories: practical swimming and competitive swimming. Practical swimming is further divided into sidestroke, dive, reverse breaststroke, treading water, rescue, etc. Competitive swimming is divided into breaststroke, crawl, backstroke, butterfly, freestyle. The grades are: Grade 3, Grade 2, Grade 1, Fitness, International Fitness .
