Background
Trampolines are elevated, essentially buoyant mesh beds or canvas sheets supported by springs or elastic shock absorbers. It is surrounded by a metal frame and used as a springboard for tumbling.
Trampolines are used for trampoline sports (sometimes called rebound tumbling). In this sport, the trampoline is used to bounce the player, so he or she can perform acrobatic moves in the air. The trampoline is also a training tool for gymnasts, divers and pole vaulters.
History
Trampolines didn't become popular until the 1900s, when circus performers made them a feature attraction. In 1936, when today's trampoline was developed by American gymnast George Nissen, it became a modern sport. In the United States, the trampoline was originally a trademark for the apparatus Nissen perfected.
Surprisingly, trampolines became popular in the United States when World War II broke out. It is used by the armed forces for recreational and physical education purposes. This is particularly important for pilot and crew training, as it helps guide trainees to understand the body posture and sensations associated with flying.
After the war, PE teachers introduced trampolines to schools because they were good for the body and fun. Its use extends to universities and student sites.
Unofficial trampoline competitions in the United States were first held in 1947, followed by official competitions in 1954. The international trampoline competition began in 1964. The International Trampoline Association has set up an international governing body to regulate the sport worldwide.
Today, trampolines are used to improve health through cardiovascular exercise. Use a mini trampoline called an aerobic rebounder to improve endurance, strength and coordination. The rebound was first manufactured in 1975 and marketed as an indoor jogging aid.
