Which Rebounder Does NASA Use?

Short answer: ultra-tough, safety-packed mini trampolines built to astronaut standards. But here’s the fun bit—these rebounder trampolines celebrities love aren’t just for space geeks. From bone strength to heart health, the secrets behind NASA’s choice will make you bounce for more.

The Rebounder NASA Uses

The NASA Rebounding Study

Back in the day, NASA needed a way to help astronauts stay fit while floating around in zero gravity. Ordinary gym gear just wasn’t practical. Enter the humble rebounder. It turned out to be one of the most effective tools for protecting astronaut health before, during, and after missions.

NASA’s findings, published in the Journal of Applied Physiology in 1980, compared treadmill running with trampoline jumping. They discovered that for the same oxygen consumption and heart rate, trampoline exercise produced greater biomechanical stimuli—making it a more efficient way to maintain conditioning (read the study here).

The Specifics of the Study

NASA’s tests compared rebounding to other forms of exercise. They found the bouncing motion worked muscles and bones harder than running on a treadmill. Yet it was kinder on the joints. That’s why their rebounders have to be durable, highly adjustable, and fitted with safety features.

Comparing Rebounding to Running

Picture this: you’re jogging down a road, pounding the pavement, knees taking a beating. Now imagine bouncing gently on a trampoline. NASA discovered the bounce created more acceleration and force through the body than running, without the same wear and tear. For astronauts, that’s priceless.

Why NASA Astronauts Rebound

Combating the Effects of Weightlessness

In space, muscles weaken and bones thin out because the body isn’t working against gravity. Astronauts who don’t train properly risk losing strength fast. Rebounding keeps their legs, hips, and backs fighting fit. It’s a simple but powerful way to fight against weightlessness.

Improving Bone Density and Muscle Mass

The bounce doesn’t just feel fun—it tells the body to build. Rebounding stimulates osteoblasts, the cells responsible for making new bone. That’s crucial for astronauts, but also for anyone worried about brittle bones later in life. It also helps preserve muscle mass, which space travel quickly eats away.

Cardiovascular Benefits

Life in orbit plays havoc with the heart. Blood pressure shifts, circulation slows, and astronauts can feel dizzy or weak. Rebounding works the heart in a safe, joint-friendly way. It boosts stamina and aerobic capacity so they’re ready for everything from spacewalking to re-entry.

Lymphatic System Stimulation

Here’s a fun fact: your lymphatic system doesn’t have a pump like your heart. It relies on movement. The up-and-down bounce of a rebounder gives it a boost, helping to flush out toxins and keep the immune system ticking over. Handy for astronauts—and for us earthlings too.

What This Means for Everyday Rebounders

Benefits Proven by NASA Research

Low-Impact on Joints

If running leaves your knees sore, rebounding could be your saviour. NASA proved it works the body harder than jogging, but with far less strain. That’s a win for anyone who wants fitness without the pain.

High Calorie Burn

A short rebounding session can torch calories quickly. Parents often joke they get their workout just chasing kids around—imagine adding a rebounder into the mix. Ten minutes of bouncing while the kettle boils can feel like a full workout.

Efficiency and Effectiveness

Busy schedule? Rebounding packs a lot into little time. It works muscles, strengthens bones, improves balance, and gives the heart a workout—all in one go. NASA’s research shows you don’t need hours at the gym to reap the benefits.

Choosing a NASA-Approved Rebounder

Features to Look For

Not all rebounders are created equal. While NASA doesn’t manufacture or endorse specific brands, their research shows why build quality matters. Look for a sturdy frame, a non-slip mat, and either high-quality springs or durable bungees. Safety padding is also essential. If you’ve ever bought a cheap trampoline for the kids and watched it sag in weeks, you’ll know why investing in quality makes a difference.

Types of Rebounders (Spring vs. Bungee)

Spring rebounders are the classic choice—firm and responsive, similar to the type tested in NASA’s research. Bungee rebounders, meanwhile, provide a softer, quieter bounce that many people prefer for home use. Think of it like choosing between a racing bike and a comfy cruiser. Both get you moving, just in different ways.
