The principle of trampoline is based on elastic force. When the trampoline is under pressure, it will deform and generate a force to return to its original shape, that is, elastic force. This elastic force enables the trampoline to provide enough rebound force to enable athletes to perform various tricks in the air.
The history of trampoline can be traced back to France, and later gradually spread to the United States. In 1947, Texas held the first national trampoline exhibition competition, and a year later trampoline became an official competition event. In 1964, the International Trampoline Federation was established in Switzerland, and the first World Trampoline Championships were held in the same year. In 2000, trampoline was listed as a competition event in the Sydney Olympics.
Trampoline is not only a competitive sport, but also provides entertainment for children in playgrounds. It not only tests the skills and strength of athletes, but also has high requirements for their physical coordination and sense of balance.
