Why do you want to take a dip in a small pool after diving?

Because after landing, the evaporation of water on the body will take away a lot of heat in the body and make the body temperature drop. If the body temperature drops quickly, it may cause muscle stiffness and convulsions, which will affect the later games. Moreover, the water put in that small pool is warm water, which can keep the body temperature by soaking in it.

Because there is chlorine gas used for disinfection in the water in diving pool, if the contestants enter the warm pool directly from diving pool, it will pollute the water in the warm pool. Therefore, before entering the warm pool, they must wash under the shower head and use them to clean the water in diving pool.

athletics diving

Athletics diving includes athletics diving and skydiving.

Track and field diving is one of the official Olympic events, which is divided into springboard diving and platform diving. During the competition, athletes take off on the springboard with one fixed end and one elastic end to complete the diving action, which is called springboard diving (the height of the springboard from the water is specified as 1 m, 3 m).

An athlete takes off on a flat and solid platform to complete the diving action, which is called platform diving (the platform is 5m, 7.5m,10m above the water).

Diving at high altitude is a very thrilling diving sport. Athletes take off from a very high cliff or a specially-made ultra-high platform, complete aerial movements and then enter the water. In America, there is an aerial stunt diving competition. The special steel platform is 48 meters high and the table is about 70 centimeters wide.

Athletes can freely choose the action of the competition, and the referee will score points, and the winner will be the one who scores more points. In Mexico, there is a traditional cliff diving competition. The cliff is 60 meters high and the sea is below. The athlete's jumping action is similar to the American 48-meter high-altitude diving. High-altitude diving is very dangerous and prone to injury accidents, so it is not common in the world.

There was diving before the Song Dynasty, and it was called "Water Swing" at that time. Performers use "swings" to make their bodies soar in the air, and then jump directly into the water after completing various actions in the air. It is breathtaking and graceful, similar to modern synchronized diving.

According to Zhao Can's Ci Lu in the Tang Dynasty, Cao Zan of Hongzhou (now Nanchang) can dive into the water, take off his clothes and sit on the water, or "swim around in the water, ever changing", which can be regarded as China's early diving.

Diving in history used to be based on who jumped farther. Diving has a long history. After human beings mastered swimming skills, they began to have simple diving activities.

As early as the 5th century BC, there were patterns on ancient Greek vases, depicting a group of lovely little boys diving headfirst. A simple diving apparatus called "Water Swing" appeared in China in the Song Dynasty.
