How many calories does bouncing on a trampet for 13 minutes burn about ? Thanks :)

Here's a site that might help
trampoline bouncing exercise, rebounding exercise equipment, bouncing on a mini-trampoline south africa (http://www.satrampoline.co.za/et-trampoline-bouncing.html)

A person weighing 70 kg spending one hour on a mini-trampoline will burn about 410 calories whilst the same person jogging for 1 hour (at a pace of 8 kilometers per hour) will burn approximately only 355 calories.

thanks :)
and haha trampet = mini trampoline :)
