Double Mini Trampoline can be likened to a combination of Athletics, Trampolining and Gymnastics. Competitors sprint down a carpeted track and hurdle onto the apparatus before performing double and triple somersaults with the same precision required on a trampoline. The only difference is that gymnasts have to land on a trampoline bed less than a quarter the size of a trampoline, before performing a dismount on to a landing mat.
In DMT competitions there are four passes, two in the preliminary round and then two in the final round. Each pass consists of one skill performed as either a mount or a spotter, followed by a dismount skill making two skills per pass.
