In Spanish, el trampolin is a diving board. When George Nissen, one of the creators of what we now know as a trampoline, came across the word in the 1930s, he adopted it as a trademark. Trampolines come in all shapes and sizes these days. Professional trampolines, such as those used in the Olympics, are constructed from a galvanised steel frame 10'W x 17'L x 45"H (305 x 520 x 115cm), attached to which, by powerful steel strings is a mat 7'W x 14'L (213 x 426cm) made from black polypropylene. This professional mat has slightly more bounce because of its increased porosity and reduced air resistance. Around the edge of the trampoline will be a padded area. Additional padded mats are available for increased safety. These usually have their own additional framework for support and are placed just over the edge of the trampoline, in case the bouncer falls towards the hard edge or is even in danger of falling from the trampoline. Home trampolines are often circular or octagonal and come in many sizes ranging from 8' to 16' in diameter. Some have a cross woven into the fabric of the mat, indicating the centre point of the trampoline. This is a safety feature aimed at helping the bouncer to stay at the safest point of the trampoline - the middle. Other safety features are available such as enclosures or nets to surround the trampoline. Some are free standing and some attach to the trampoline itself. All are designed to prevent the trampoliner falling and sustaining injury. This is particularly important if your trampoline will be sited on or near a hard surface, such as a patio or deck. A cover is a good idea as it will keep your trampoline free from debris such as leaves and bird droppings. Not only will it be kept clean, but the danger of slipping on the mat will be minimised. An anchor kit will stop your trampoline moving around when in use and will keep in tied down in the event of strong winds, which can cause a great deal of damage to trampolines, despite their sturdy structures. For small children, a trampoline ladder will help to avoid accidents when getting on and off the trampoline. Trampolining is fun and great aerobic exercise for all age groups. It improves co-ordination, balance, rhythm and timing and is useful training for other sports such as skiing. In fact, it has so many health benefits that we will make it the subject of a separate article. |
