Sport isn't just about running or a ball. There are several Olympic disciplines that seem to represent only fun leisure at first, but turn out to be governed by countless rules and international federations. For example, who would have thought that trampoline jumping would be integrated into the sports disciplines of the Olympic Games, when we think that trampoline is only used at home to amuse young turbulent children. At present, countless professionals of this sport evolve in the various regional and international leagues existing. Trampoline is a discipline in its own right included in the great circle of gymnastics. The goal of the game is to jump on the trampoline and perform as many spectacular tricks as possible. The trampoline itself is a material composed of a metal frame measuring 5m by 3m that supports a canvas stretched horizontally and is held at a height of 1m15 from the ground by metal feet. In order to ensure a better consistency to the canvas, nearly 120 springs keep it stretched and are covered with small carpets to avoid accidents. Safety precautions require the installation of several protective mattresses at the ends of the machine. As a true acrobatic discipline, a trampoline event requires a sequence of ten jumps without any figure repetition or intermediate candle. At each jump is then awarded by the judges a score that will decide the winner among all the competitors. Note that the figures must be universal and regulatory. Among the most famous and easy acrobatic elements are the Salto back or Back, the Vrille, the Barani which is a combination of a front salto and a half spin, as well as the Rudy out. Examples of spectacular figures are on the other hand the Randy out, the Barani in full out or the Triffis half, the Half in rudy out and the Miller for connoisseurs. In order to optimize your chances, it is wise to perform a large high jump in order to have maximum momentum and time to perform the acrobatics. Indeed, the more the body is rotating in the air, the more the points acquired multiply. It is therefore not uncommon to see professional jumps of more than 8 meters from the ground, especially in men. A trampoline regulation competition can be played individually or in a team where the movements will have to be synchronized. Regarding the small history of the trampoline, it makes its appearance in the twentieth century in the circus of Italian trapeze artists "Due Trampoline". At that time, the principle was only to bounce off the protective net and perform spectacular acrobatics. Trampoline Later in the 30s, the ancestor of the real trampoline we know today was born, thanks to the initiative of the American George Nissen. This physical education teacher and diving professional invented the trampoline device and made it an object of trade, which the army will hasten to use for the training of its pilots. After World War II, intercollegiate trampoline competitions were held in the United States. The regulations applied at that time are still archaic and consisted in performing as many tricks as possible in the space of three minutes. Rehearsals were not yet prohibited, which pushed gymnasts to repeat the same tricks throughout the allotted time. The trampoline will be a great success throughout the globe and will see the creation of the first national federation of a European country in 1964 in Scotland and that of an international federation some time later. At present, this FIT now has more than 42 national member federations. In the same year of 1964, the trampoline had its first world championship held in London and which was done without any codified rules. The first universal rules were not listed and put into force until 1983. Today, a European Championship and a World Championship are held alternately every two years, to which is added a World Cup Circuit. But the biggest turning point in the history of trampoline remains the year 2000 which is none other than the year of entry of the trampoline in the official events of the Olympic Games. During these Sydney games, the individual trampoline events are competed for the first time in J.O and were dominated by the Russians.
