"Rebound Exercise is the most efficient, effective form of
exercise yet devised by man." A. Carter summarized a NASA study
in 1979, a study which NASA published in 1980 in the Journal of
Applied Physiology. NASA says, "...for similar levels of heart
rate and oxygen consumption, the magnitude of the bio mechanical
stimuli is greater with jumping on a trampoline than with
running, a finding that might help identify acceleration
parameters needed for the design of remedial procedures to avert
deconditioning in persons exposed to weightlessness. “ When
Rebounding, three natural forces are at work: gravity,
acceleration and deceleration. In the up and down movement of
bouncing, your body is subjected to these three forces and each
time you bounce into the mat (at its deepest point) your body
comes into a G-force (Gravity force) of two to three. As a
consequence, literally each cell of your body experiences a
G-Force which is two or three times stronger than normally. It
is as if your weight would double or triple
