High-altitude diving is an extreme sport. It takes only a few seconds to "fly" in the air, during which a series of waist twisting and turning movements are performed. When it reaches the surface, the speed will be at least as high as 6 miles per hour. When you fall into the pool, you must ensure that your feet "land" first, and your body must remain absolutely nervous and straight. The huge impact is almost similar to falling on the concrete floor. If you are not careful, the diver may break his skull and die on the spot.

There is a gravitational acceleration under the gravity of the earth. The higher the height, the greater the speed when it reaches the water surface, the greater the impact force on the water surface, and the greater the force on people or objects, so that the human body can't bear such a large force and be destroyed. Of course, it depends on the contact area between you and the water surface. The larger the contact area, for example, if you shoot it horizontally, the greater the force; If you plant it, the total force will be small.

Athletes who dive at high altitude must undergo rigorous training in order to keep their bodies in a perfect state, so that they can cope with the huge impact when they collide with the water. When divers touch the surface of the water, they often encounter spasms and cramps because of the great gravity influence on their bodies, and a large amount of adrenaline will flow into the blood vessels.

As this is a tough sport, high-altitude divers can only jump 15 times a day at most, and they must receive muscle tissue massage immediately after each dive.

In the United States, there is a high-altitude stunt diving competition. The specially-made steel platform is 48 meters high and the table is about 7 centimeters wide. Athletes are free to choose the action of the competition, and the referee will score, and the one who scores more will be the winner. In Mexico, there is a traditional cliff diving competition. The cliff is 6 meters high and the sea is below. The athletes' jumping movements are similar to those of 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. It is understood that there are only 35 people engaged in extreme diving at high altitude in the world, and there are more than 1 world-class masters.
