How Do Trampolines Work?

A Lesson in Physics

Bouncing on a trampoline involves several forces at play, according to MadSci.org contributor Tom Cull: your weight, the spring and nylon that restore the trampoline back to its original form after each bounce, and the impulse or driving force you create while jumping.

The physics behind trampoline operations goes back to a classics high school physics equation, Total E = KE + PE , according to the website trampolinesafety.com. When you jump on a trampoline you are losing velocity in kinetic energy (KE) while gaining potential energy (PE). The total amount of energy used is equal to the kinetic energy plus the potential energy. The harder and faster you jump the greater the KE, PE and E will be thanks to the culmination of all forces involved. This is why trampolines are such great cardio and strength-training tools.

The Rebound Concept

Rebounding on a trampoline by jumping up and letting yourself come back to the ground provides an aerobic workout that is similar to jogging or jump roping. Unlike other cardio-vascular activities, however, trampoline rebounding offers a low impact alternative that puts minimal stress on your joints, knees, and lower back. By pushing off for each jump, you are also doing strength training by firming up leg muscles including calves, thighs and buttocks. Trampoline jumping also works to tighten your core stomach muscles.

Rebounding for Maximum Fitness

You can elevate your heart rate and burn more calories by rebounding as fast and high as possible. Maximize your aerobic conditioning by jumping at least 20 to 30 minutes each time you get on a trampoline.
