Differences Between a Trampoline and a Rebounder?
Although rebounding grew out of the sport of trampolining there is a vast difference
between trampolining and rebounding. Rebounding is an in-home exercise from which a wide range of people can benefit. You can have any or no activity
level prior to using it. Also, the rebounder does not go above 4 G’s (the “G” indicates units of gravity, 1 G is your body weight so 4 G’s is 4 times
your body weight) . This means that you will never have that out-of-control feeling you may experience on a trampoline. It will not cause you injury
the way that a trampoline can if you are not cautious – such as bouncing yourself off the trampoline or jumping so high that you land on the wrong body
part and injure yourself.
Brief History of Rebounding
The first rebounder was created in 1938 and the very first units were used for vision therapy –
to correct vision. The rebounder assisted in strengthening the muscles of the eye. (I will explain in greater detail later how the rebounder works within the body)
In 1977 Al Carter who is known as the father of Rebound Exercise, began studying rebounding
and the physiology behind it after his family had tremendous results from it. For 9 months, the Carter family used the rebounder daily for 45 minutes
and as a result they had tremendous health and strength to show for it, increased endurance, and better coordination. As a result of his research he
wrote a book called “Rebound to Better Health.”
In the early 80’s, in response to Al Carter’s research, over 100 manufacturers began making rebounders and
b/c of competition, inexpensive materials were used causing people to be unhappy as their rebound units either broke or jarred their body.
In 1990, a company called NEEDAK began making these folding units. They are safe, quality
rebounders that are called Soft-Bounce rebounders. For those of you that are interested in trying it you will see that it is not jarring at all and
very easy on the body.
Why Rebounding is Important
Rebound exercise utilizes the forces of acceleration, deceleration, and gravity to equally strengthen
every cell in the body at once while flushing the lymphatic system without shock to the joints. (I will now break this definition down so you have a better
understanding of how it works)
In essence there are two benefits of rebound exercise, (1) overall physical health benefit and (2) cleaning out
the lymphatic system
(1) Physical benefit: When you jump up and down on the rebounder a loaded force is placed on each cell on the down
bounce and the cells adapt to the load by getting stronger. In essence, all the cells weigh more as the body comes back down to the mat. It is as if each cell is weight lifting.
The common denominator for all types of exercise is the opposition of gravity, ex. Walk, run, swim, tennis, weight lifting, etc.
Gravity pulls us toward the center of the earth and therefore can be visualized as a vertical force. All exercise has 2 other forces coming into play as well: Acceleration (starting) and
Deceleration (stopping). All other forms of exercise experience these 2 forces of acceleration and deceleration on a horizontal plane – meaning you’re moving forward. The uniqueness of rebounding
is that it utilizes the 3 forces of acceleration, deceleration, and gravity on the same vertical plane- this is called triple loading b/c according to Einstein’s theory of gravity; the body does not
know the difference between the 3 forces of acceleration, deceleration, and gravity. It computes them as 3 gravities and reacts to this triple force by telling the cells to adjust positively. As a result,
rebound exercise strengthens the body at a cellular level.
(2) Flushing the Lymphatic System: We tend to think of our lymphatic system as the waste removal or garbage system for the bloodstream.
It is important that this system operate efficiently. If it were to shut down for 24 hours the human body could not survive. The 3 functions of the lymphatic system are: flow of lymph along the
lymphatic veins, return of blood proteins to circulation, and filtration of the lymph by the lymph nodes. The lymph is cellular fluid that bathes each cell. Healthy lymph is clear and flows through
the lymphatic vessels freely. There is 3 to 4 times as much lymph as blood in the body. B/c the lymphatic system has no pump (like the heart does for the circulatory system); it flows very slowly,
depending on body movement for its flow.
There are 57 different chemicals that are secreted in the lymph fluid, so exercise, in particular rebounding, affects our emotions and nervous system
in a positive way. Lethargy, foggy thinking, depressive symptoms, headaches, and symptoms of anxiety could be signs of an inefficient immune system that could eventually lead to physical or emotional illness.
How the Rebounder flushes the lymphatic system: As the body bounces upward, the one-way valves in the lymph veins are closed. At the top of the bounce, a split-second
of weightlessness is experienced, then as the body comes down, the fluid in the lymph veins begins to flow up, opening the valves. At the bottom of the bounce, gravity closes the valves. The deceleration causes the cells to dump
their waste into the lymph. With the next bounce, the process starts all over again, opening the valves, and flushing the waste. According to the research, 2 minutes of health bouncing is enough time to completely flush out the
entire lymphatic system and increase white blood cells. In one hour after rebounding, the white blood cell count is back to normal. Therefore, the ideal regimen for a person regaining health is to health bounce (which I will
explain more about in a minute) 1-2 minutes every hour. This will help to keep the white blood cell count high and help to keep your lymphatic system flushed.
Activity is vital to the human body and rebound exercise is the most efficient way to activate that lymph pump. Rebounding provides the greatest change in pressure
with the least amount of body effort.

Rebound Exercise makes gravity work in your favor to give you the best whole body workout available. Check out the following list of other benefits(3) of rebounding:
1 Increases the capacity for respiration.
2 Circulates more oxygen to the tissues.
3 Establishes a better equilibrium between the oxygen required by the tissues and the oxygen made available.
4 Lightens the load on the heart.
5 Tends to reduce height to which the arterial pressures rise during exertion.
6 Lessens the time during which blood pressure remains abnormal after severe activity.
7 Aids in lymphatic circulation as well as the flow in the veins of the circulatory system.
8 Encourages collateral circulation.
9 Strengthens the heart and other muscles in the body so they work more efficiently.
10 Allows the resting heart to beat less often.
11 Stimulates the metabolism.
12 Promotes body growth and repair.
13 Adds to the alkaline reserve of the body, which may be of significance in an emergency requiring prolonged effort.
14 Reserves bodily strength and physical efficiency.
15 Expands the body’s capacity for fuel storage and endurance.
16 Improves coordination.
17 Muscular vigor from increased muscle fiber tone.
18 Enhances digestion and elimination.
19 Allows better and easier sleep and relaxation.
20 Tends to slow down aging.
