Why Rebound?

Glad you asked. Turns out that there are many benefits to rebounding (including NASA’s research showing that rebounding can be more than twice as effective as treadmill running).

The idea of rebounding has been around for a long time, but it gained popularity in the 1980s when NASA studied its benefits while trying to find an effective way to help astronauts recover and regain bone and muscle mass after being in space. Astronauts can lose as much as 15% of their bone and muscle mass from only 14 days at zero gravity, so NASA needed a way to help reverse this damage.

Some of the findings of the NASA study:

• When the astronauts were tested while running on a treadmill, the G-force measured at the ankle was over twice what it was at the back and head. This means that the foot and leg absorb much of the force when running, which can explain the higher rates of foot, shin and knee problems from running (especially running incorrectly). On a trampoline, the G-force was almost identical at the ankle, back and head and at a lower level than that of the G-force at the ankle on a treadmill. This shows that rebounding can exercise the entire body without excess pressure to the feet and legs.
• “The external work output at equivalent levels of oxygen uptake were significantly greater while trampolining than running. The greatest difference was about 68%.” In other words, the increased G-force in rebounding means you get more benefit with less oxygen used and less exertion on the heart.
•  ” . . averting the deconditioning that occurs during the immobilization of bed rest or space flight, due to a lack of gravireceptor stimulation (in addition to other factors), requires an acceleration profile that can be delivered at a relatively low metabolic cost. . .for equivalent metabolic cost, and acceleration profile from jumping will provide greater stimuli to gravireceptors.” In other words, the acceleration and deceleration of rebounding provides benefits on a cellular level and at a greater rate than other forms of exercise like running.
