A trampoline is a tight sheet of canvas that is attached with springs to a metal frame, and used for gymnastic springing and tumbling. The springs provide a rebounding force which thrusts the jumper high in the air.
The name originates from the Spanish – “trampolin”, meaning a diving board. It is also assumed that the trampoline originated from the Inuit people, a group of Eskimo people who used to toss each other in the air on a walrus skin. Some evidence also indicates that in England, people were tossed in the air by a number of others holding a blanket.
The first modern trampoline was built around 1934 by two enterprising men, George Nissen and Larry Griswold. While it was initially used to train acrobats and gymnasts, it soon gained popularity in its own right.
There are two types of trampolines, recreational and competitive. Recreational trampolines can come in various shapes, although they are mostly circular or rectangular. They are made of water proof canvas or polythene material. They are less sturdy, and their springs are not all that strong.
The frame of a competitive trampoline is made of steel, rectangular in shape and has a size of 14 feet by 7 feet and made with strong fabric.
A lot of care needs to be taken while using a trampoline, because bouncing off one can cause major injuries. However, the extent of injury can be reduced if the trampoline is buried, so that the bed is close to the surface in an attempt to lessen the impact when one bounces off. Installing pads over the spring and frame will also reduce the extent of injury.
As a competitive sport, trampoline jumping has developed and has been part of the Olympic Games since the year 2000. On a modern competitive trampoline, a jumper can bounce up to a height of 10 meters. Trampolines also feature in the competitive sports of Slamball and Bossaball, which is similar to basket ball and volley ball respectively.
In order to keep trampolines fun and injury free, a few precautions need to be taken. Ensure that all metal pieces are covered with foam, and set up the trampoline well away from pools, trees, sheds and other possible hazards. Children under 16 should always be supervised, and those under six should not be allowed to use it because they lack the necessary coordination. Furthermore, only one person should use the trampoline at a time. Leave the advanced maneuvers for professionals, and consider enrolling your child in a gymnastic club before buying a trampoline.
