Why is there a hose flushing by the pool in diving competition?

Diving has always been one of the more advantageous events in China, so every diving competition will naturally attract many viewers' attention. Many people watching the game will have a question, why there is always water pipe flushing near diving pool. In fact, this device for flushing water into the swimming pool is very useful. It's called a wave maker.

Wave-making machine is easy to understand, that is, something used to make ripples. The main purpose is to disturb the calm water surface and make it ripple, so that athletes will not have the illusion of ups and downs when jumping. This machine was officially put into use at the Sydney Olympic Games. Needless to say, there were many jokes before it was used. Because when athletes jump up and down on the beach, especially in indoor diving halls, it is calm, which makes people feel that there is no water in the pool. It happens from time to time, and the aerial action of 10 meter platform is perfectly completed, and suddenly he subconsciously holds his head when entering the water. I didn't know until I asked. Because the water surface was too smooth, I felt that there was no water in the pool for an instant, and I protected myself by the way.

The wave maker can not only prevent athletes from having illusions when diving, but also help athletes control the distance. Diving needs to complete many somersaults in just a few seconds, and you need to adjust your angle before falling into the water. In view of sometimes take-off or imperfect movements, the distance into the water is naturally a floating value. Therefore, when the water surface has ripples, athletes can better judge their distance from the swimming pool. Especially when entering the water, you can better complete your finishing action and reduce mistakes.

To sum up, small flushing devices can be used in diving competitions. At this time, I have to sigh, the power of technology. With the progress of science and technology, the equipment of sports events is also updated day by day, which is of great help to the safety of athletes and the truth of their achievements. It is because of these advances that we, as spectators, can see a wonderful game.
