Trampoline

Updated: 2006-08-19 15:16

There are two types of trampoline, recreational and competitive.

Recreational trampolines are less sturdily constructed and their springs are less strong. They may be of various shapes, though the most usual are circular, octagonal or rectangular. The fabric is usually a waterproof canvas or woven Polypropylene material.

The frame of a competitive trampoline is made of steel and can be made to fold up for transportation to competition venues. The trampoline bed is rectangular 428 cm (approx. 14 feet) by 214 cm (approx. 7 feet) in size[1] fitted into the 520cm x 305cm (17' x 10') frame with around 110 steel springs (actual number may vary by manufacturer). The bed is made of a strong fabric. The fabric can be woven from webbing which is the most commonly used material. However, in the 2007 World Championships to be held in Quebec City a Ross (or "Two-String") bed, woven from individual thin strings, will be used.

In any trampoline, the fabric bed is not elastic itself, the elasticity is provided only by the springs.
