How many swimming strokes are there?

Everyone knows that swimming is very good for people's health. Many people are now keen on swimming. So in this case, everyone is more knowledgeable about swimming. Many people are looking for their favorite postures when swimming at school, but they don’t know much about the specific postures. The following is a detailed introduction to several swimming postures.

Freestyle

One of the swimming events. It was listed as an official event at the first Olympic Games in 1896. Freestyle swimming is not restricted by any posture. Crawl stroke is the fastest, so crawl stroke becomes the only posture of freestyle swimming. The crawl stroke is like crawling, with the arms paddling and the legs kicking the water up and down alternately. This posture has a reasonable structure, low resistance, and uniform speed. It is currently the fastest and most energy-saving swimming posture in the world.

The basic technical characteristics of freestyle are that the human body lies prone in the water with the head and shoulders slightly above the water surface. When swimming, the torso rolls left and right around the longitudinal axis of the body, and the two arms take turns paddling to propel the body forward. After the hands enter the water, the stroke path is S-shaped, and the breathing and stroke movements are coordinated. As your arms stroke vigorously, use the troughs formed by the water on both sides of your head to inhale.

breaststroke

Breaststroke is an ancient swimming style. According to historical records, similar swimming styles existed in China, Rome, and ancient Egypt 2,000 to 4,000 years ago. On August 24, 1875, the famous swimmer M. Webb crossed the English Channel using the breaststroke, which took 21 hours and 45 minutes. The breaststroke was the first stroke to be adopted in swimming competitions in the early 19th century. However, due to the slow speed of breaststroke, sidestroke and crawl stroke appeared in competitions, and fewer and fewer people used breaststroke. It was not until the 3rd Olympic Games in 1904 that breaststroke was separated from other strokes.

Butterfly stroke

During the period from 1924 to 1936, the biggest innovation in breaststroke was that after the stroke, the arms no longer moved forward from the water. Instead, the arms were moved in the air while still using the breaststroke kick and leg clamping action, resulting in a variation of breaststroke - butterfly stroke. When doing the butterfly stroke, the body lies prone in the water, relying on the powerful paddling of the arms and the wave-like kicking movement of the legs to propel the body forward. There is no fixed body posture.

Backstroke

One of the swimming events. It was listed as an official event at the 2nd Olympic Games in 1900. Backstroke includes reverse breaststroke and backcrawling. The reverse breaststroke is the earliest form of backstroke, with movements similar to breaststroke, but the body posture is opposite. That is, the person lies on his back on the water, and the arms paddle backwards from behind the head along the sides of the body. The backstroke competitions in the first few Olympic Games were all conducted using the reverse breaststroke stroke. When doing backstroke, the body lies almost horizontally in the water, with the chest naturally stretched in a straight line with the abdomen, the head submerged in the water, and the face above the water. When swimming, the head always remains upright and the torso rotates naturally around the longitudinal axis due to the alternating paddling movements of the arms.
