The amount of calories a participant burns while jumping on a trampoline varies, but AZCentral.com gives an average example. If a 150-pound adult jumps on a trampoline for 30 minutes, she would burn approximately 125 calories.
The height and weight of the jumper affect how many calories are actually burned. AZCentral.com explains that a 200-pound adult jumping for 30 minutes burns 10 percent more calories than the 150-pound adult. Other factors that affect the number of calories burned include the type and intensity of the jumps. A participant can add flips, arm swings or hold weights to increase the workout's effectiveness.
