The South African Gymnastics Federation’s National Training Centre at Matsport Centre in Eldoraigne Centurion, has undergone a makeover
The pit, which is 26 meters long and 2m deep, has been under construction during the month of December. The unique pit has a trampoline base 0.7 meters above the pit floor, with the remaining 1.3 meters to be filled with foam. This trampoline at the base of the pit allows for less dust and more elasticity for when the gymnast lands on the foam. …
FIG Age Group Training Camp and competition this weekend.
Comment from Dr. Bill Sands:
Just a short comment on trampoline pits. I have seen, more than once, that the weight of the foam on the trampoline bed presses the bed down such that the foam rests on the bottom floor of the pit. I have built a camera, light, and telescoping pole to look under the trampoline so that one can see if the trampoline remains off the floor. I know of one very serious injury where the victim hit the concrete of a trampoline-type pit. Moreover, when I stood in the foam of this pit, I could jump and my feet struck the floor.
I would just like to caution people to take considerable care in using this type of pit design. Although pit foam seems incredibly light, by accumulation the foam can weigh enough to push the trampoline bed down to the floor surface that the bed was designed to avoid.
