It is one of the sports where the margin for error is so slim. You can be in the lead and one little small movement finishes you. This means that there is often a surprise winner. The really strong nations are Russia, China and Canada." The top competitors in the world are still genuine high-flyers though, reaching heights of up to 10 metres during their routines. Although it forms part of the gymnastics programme it shares some similarities with diving in terms of the suppleness and skill needed to compete at the top level. The two sports also share the same terminology - back-flips and half-pikes feature in both. Lee Brearley and Jaime Moore were the first Britons to compete when trampoline made its Olympic debut at the Sydney 2000 Games. Britain had previously produced world men's champions Paul Luxon (1972) and Stewart Matthews (1980) as well as Sue Shotton, who took the 1988 women's world title. Gymnastics requires strength, mobility, endurance, flexibility, body control and coordination. The high level of physical fitness needed to excel helps encourage a healthy lifestyle, including regular physical activity and eating a well-balanced diet. The wide range of movements involved in trampolining works every muscle in the body and burns approximately 410 calories per hour. Jumping on the trampoline - or rebounding - has been discovered by NASA scientists to be up to 68% more effective exercise than jogging. The effort of rebounding develops both upper and body strength without putting undue strain on joints or muscles, thus reducing the risk of injury. Gymnastics is a breathtaking sport featuring a range of disciplines such as artistic, trampoline, acrobatics, aerobics and tumbling. It is enjoyed by an estimated four million people in the United Kingdom.
