Trampoline

Prepare to be dazzled by the athletes in the Trampoline competition at the London 2012 Games, the newest of the three Gymnastics disciplines on the Olympic program.

Devised in the 1930s at the University of Iowa, the first modern trampoline was initially used as a training tool for tumblers, astronauts and athletes. However, it grew in popularity to such an extent that in 1964 the first ever Trampoline World Championships were held at the Royal Albert Hall in London.

Since making its Olympic debut at the Sydney Games in 2000, the sport has consistently featured awe-inspiring displays of acrobatic excellence, with athletes jumping to heights of up to 10 metres.

History of Trampoline at the Olympic Games

Trampoline Gymnastics is a relative newcomer on the Olympic programme; it made its debut at the Sydney 2000 Games.

The basics

Gymnasts perform a series of 10 skill routines, with a variety of single, double and triple somersaults with and without twists. Precise technique and perfect body control are vital for success, with judges delivering marks for difficulty, execution and time of flight, minus penalties.

Competition format

Each competition for men and women features two phases: the qualification round and the final round. Athletes perform two voluntary routines in the qualification round: in the qualification round, the first routine (with two skills counting for difficulty) focuses on simplicity and excellent execution, while the second exercise has no difficulty limitations. The eight athletes with the best scores advance to the final for one more voluntary routine of 10 different skills, which determines the results of the competition.

Officials

Eleven judges watch the routine and award scores for difficulty, execution and time of flight. Marks are taken off for infringements and errors.

Keys to success

Athletes are judged against a strict set of criteria where every part of the routine must be as near to perfection as possible. The angle of the limbs, the position of the feet, the moves and finish must all be of the highest standard.

Breaking the rules

As well as being judged against an exacting set of criteria, where poor execution will lose points, athletes can also be penalised for taking too long to start their routine, or major infringements such as landing on the frame of the trampoline.
