It’s crazy, but it works,” said C. E. (Pat) Mueller, director of recreational sports at the University of Minnesota for thirty years. “I’ve seen a lot of sports fads come and go,” said Mueller,an associate professor with a master’s degree in physical education. “But this thing is so phenomenal – It’s the exercise of the future.

Rebound exercise is the most efficient, effective form of exercise yet devised by man.”

“. . . 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.”

The above statement is one of several made in a scientific study published in the Journal of Applied Physiology 49(5):881-887, 1980, which confirms many of the statements previously made in the “Miracles of Rebound Exercise”. The research was performed by the Bio mechanical Research Division, NASA-Ames Research Center, Moffett Field, California, in cooperation with the Wenner-Gren Research Laboratory, University of Kentucky, Lexington, Kentucky.

The four scientists, A. Bhattacharya, E.P. McCutcheon, E.Shvartz, and J.E. Greenleaf, secured the assistance of eight young men between the ages of 19 and 26 to each walk, jog,and run on a treadmill which was operated at four different speeds and then jump on a standard sized trampoline at four different heights to compare the difference between the two modes of exercise. Although treadmill running had been studied many times before, the scientists found that

“. . . measurements of the necessary variables have not been reported previously for trampoline exercise.”

The trampoline testing was conducted at least one week after the treadmill testing.

The six measurements which were taken on all eight of the subjects were:

1

A pulse before exercising.

2

A pulse immediately after exercising.

3

The amount of oxygen consumed while exercising.

4

The amount of G-force experienced at the ankle while exercising.

5

The amount of G-force experienced at the lower-back while exercising.

6

The amount of G-force experienced at the forehead while exercising.

The pulse was obtained by a battery-powered electro-cardiographic unit taped to the subject’s body which transmitted its signals to a custom-designed receiver which in turn recorded the information by electronically writing it on a chart.

The oxygen consumption was measured with a K-meter which the subject carried on his back.

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 plexiglass holders that were taped to the ankle, the small of the back, and the forehead.

After a thorough medical examination, the healthy students have issued a pair of shorts and new Nike running shoes to standardise the conditions to be measured. They gave familiarization sessions on laboratory procedures, treadmill running and trampoline jumping to ensure the exercise techniques would be the same.

Each student then walked or ran four different speeds on the treadmill with a five to ten minute rest period between runs while the scientist recorded their statistics and compared them with previous treadmill studies for accuracy.

A week later, these same athletes returned to bounce on a trampoline at four different heights with a 5 to 10 minute rest period in between exercise sessions. Again the scientists recorded their statistics, only this time; they had no previous studies to compare them to. Since trampolining had not previously studied, the only 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.”

Results Revealed by Nasa

1

The G-force measured at the ankle was always more than twice the G-force measured at the back and forehead while running on a treadmill.
This helps to explain shin splints and knee problems, especially when the natural shock absorbing system of the body becomes so fatigued that it doesn’t do its job correctly, thus throwing added unexpected forces on already tired muscles, ligaments and tendons, forcing them beyond the point of rupture.

2

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 healthy individual.
This makes it possible to exercise the entire body knowing that there is no undue pressure applied to 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.

3

The external work output at equivalent levels of oxygen uptake was significantly greater while trampolining than running. The greatest difference was about 68%.
The efficient use of the vertical forces of acceleration and deceleration to produce internal loading by directly opposing the gravitational pull develops more bio mechanical work with less energy expended. Thus less oxygen used and less demand placed on the heart.

4

While trampolining, as long as the G-force remained below 4-G’s, the ratio of oxygen consumption compared to bio mechanical conditioning was sometimes more than twice as efficient as treadmill running.
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 rebound exercise on rebound units have been measured only as high as 3.5-G’s,so that any activity on a rebound unit is more efficient than treadmill running at any speed.

5

With the G-force the same as or greater than 4-G’s ” . . there was no significant difference in the oxygen uptake between the two regimens”.
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 the cells are still below their rupture threshold providing a safe way to exercise.

6

” . . averting the deconditioning that occurs during the immobilisation 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.”

Conclusion

This statement verifies the fact that rebound exercise is an excellent exercise for our senior citizens, those physically disabled, those who are recuperating from an accident or injury, or anyone else who needs exercise but is hampered by a pre-existing physical condition.
