The country where trampoline first appeared was France. Because there was an acrobat who performed some bouncing movements in the safety net in the air and showed them to people, people thought this way was very interesting, and the movements that could be completed were both beautiful and beautiful, so trampoline gradually became active in people's field of vision. Later, trampoline was introduced to America. Because people will consume a lot of physical strength in the process of jumping, so the follow-up people made some trampolines. 1947, the United States held the first national trampoline exhibition competition, and then the Federation of trampoline management associations began to be established. Trampoline was officially listed as an Olympic event in 1997.
Later, after trampoline was introduced to China, China held related tournaments and youth competitions every year. The frame of trampoline is metal, and its inner bed surface is very thin. Some thick mats are often laid next to the trampoline, which can prevent people from falling and reduce injuries. Trampoline is divided into two events in the competition, one is single jump and the other is online. Single jump refers to the use of a dedicated runway to complete a series of actions, including somersaults, backflips, etc., and it needs to land on the mat perfectly after completion. As mentioned in the above article, trampoline can better consume people's physical strength, so it will make people stronger and exercise their jumping ability and breathing ability.
