REBOUNDING EXERCISE THROUGH THE AGES
Leaping and rebounding has always been a natural act tapped by the young in their play, forming an important part of recreation and physical education. From early childhood, bouncing, otherwise known as rebounding, forms an instinctive element of spontaneous and organized play.
The design and marketing of commercial mini trampoline rebounders over the past twenty years, has encouraged the use of mini trampolines for rebounding exercise workouts for home exercise highlighting the numerous
health benefits that rebounding can bring!
As far back as the middle ages, travelling
acrobats specialized in plank leaping, rebounding over a variety of objects,
including each other.
Eskimos stretched walrus skins between stakes
in the ice, bouncing zealously off and upon them. Inspired by the trapeze
artist, ending his act rebounding into a safety net, George Nissan set about designing the first
trampoline in the mid 1930's.
Throughout World War Two, the American Armed
Forces adopted rebounding equipment as part of their training programmes, to aid the
development of aerial orientation, co-ordination, and motor skills.
NASA RESEARCH REPORTS SUPERIOR BENEFITS OF REBOUNDING EXERCISE MINI TRAMPOLINES
Mini trampolines, specifically designed
for use as home exercise rebounders, began to flood the home exercise
equipment market in the 1980's.
In the past twenty years nearly every commercial company selling rebounders or a mini trampoline rebounding concept refers to the NASA research and reports on rebounding exercise.
So what did the NASA research into rebounding exercise reveal?
Since man has been exploring space, astronauts
have been faced with the effect of zero gravity,
which threatens to weaken their bones and tissues, through lack of stress upon
their body cells.
For this reason NASA scientists carried
out the first-ever research into using a trampoline, with evidence
surfacing to suggest that rebounding on a mini trampoline provides superior
The concept of rebounding on mini
trampolines was consequently introduced as 'rebounding' around twenty years ago,
citing NASA research as ' the most efficient and effective form of exercise ever
Four scientists, A, Bhattacharya, E. p, McCutcheon, E. Shvariz, and J, E.
Greenleaf, secured the assistance of eight men between the ages of 19 and 26 to
each walk, jog, and run on a treadmill, operated at four speeds, and then jump
on a standard sized trampoline at four different heights to compare the
difference between the two modes of exercise.
Treadmill running had been studied before; however the scientists found
"...measurements of the necessary variables have not been
reported previously for trampoline exercise."
testing was conducted at least a week after the treadmill testing. The six
measurements that were taken on all eight subjects were:
A pulse before exercising,
immediately after exercising, amount of oxygen consumed while exercising, amount
of G-force experienced at the ankle while exercising , amount of G-force
experienced at the lower-back while exercising, and amount of G-force
experienced at the forehead while exercising.
The pulse was obtained by a battery-powered electrocardiographic unit taped
to the subject's body which transmitted signals to a custom designed receiver,
in turn recorded the information by electronically writing it on a chart.
The oxygen consumption was measured with a K-meter that the subject carried
on his back.
NASA CONSIDERED REBOUNDING TO BE WHOLE BODY EXERCISE WITH EQUAL STRESS PLACED ON ALL BODY CELLS - IDEAL FITNESS
The G-force experienced by the ankle, back and forehead of each of
the university students was measured by small sensitive accelerometers which
were placed in Plexiglas holders that were taped to the ankle, the small of the
back, and the forehead.
The only studies
previous studies available were the preliminary studies
which began in August of 1977 on passive restrained humans and animals exposed
to increasing frequency and amplitude of vibration forces designed to increase
heart rate and metabolic activity,
"These responses measured by whole-body
vibration resemble those during mild exercise and suggest that perhaps body
vibration could be used in place of exercise for those who are ambulatory.
The results of trampoline exercise
vs. treadmill study were startling to the scientists Following are some of the results revealed by this team
of scientists from NASA
makes it possible to exercise the entire body knowing that there is no undue
pressure applied to any part of the body such as the feet, ankles, and legs, and
at the same time knowing that each part of the body is receiving the necessary
environmental stresses it needs to become stronger cell by cell.
Vertical forces of acceleration and deceleration to produce internal loading by directly opposing the gravitational pull develops more biomechanical work
The efficient use of the vertical forces of acceleration and deceleration to
produce internal loading by directly opposing the gravitational pull develops
more biomechanical work with less energy expended, thus less oxygen used and
less demand placed on the heart.
It is Important to note that although this experiment was performed on a
trampoline where the participants were able to develop a G-force as high as
8-G's, the efficient use of energy was below 4-G's.
People involved in rebounding exercise
workouts on rebounding units have been measured only as
high as 3.5-G's, (United States Air Force, Dr. Ward Dean) so that any activity
on a rebound unit is more efficient than treadmill running at any speed.
"For similar levels of heart rate and oxygen consumption, the magnitude of
the biomechanical stimuli is greater with jumping on a rebounder trampoline than
with running, a finding that might help identify acceleration parameters needed
for the design of remedial procedures to avert de-conditioning in persons exposed

The above statement is one of several made in
a scientific study
published in the Journal of Applied Physiology
49(5): 881-887, 1980,
with research performed by the Biomechanical Research Division, NASA-Ames
Research Center, Moffett Field, California, in cooperation with the Wenner-Gren
Research laboratory, University of Kentucky, Lexington, Kentucky.
While jumping on a trampoline, the G-.force was almost the same at all three
points, (ankle, back, forehead) and well below the rupture threshold of a normal
"The external work output at equivalent levels of oxygen uptake was
significantly greater while trampolining than running.
The greatest difference
was about 68%." Rebounding on quality mini
trampolines provides low-impact fitness training for the whole body - providing highly effective cardiovascular and

WHY REBOUNDING ON QUALITY MINI TRAMPOLINES IS KIND TO YOUR JOINTS
Even when a person is able
to develop a force on the trampoline of more than 4- G's, although it is no more
efficient as far as oxygen consumption than running, it is still much better on
the lower extremities because all of the cells of the body are still below their
rupture threshold providing a safe way to exercise.
