When we bounce on the trampoline we are working calisthenics (using our own bodyweight) and against the constant force of gravity, which runs resistance through all 50 trillion cells of our body. As you are reading this, also consider that "weight", by definition, is mass X acceleration.
Rebounding offers 2 extra forces related to velocity or change of velocity and the forces are called acceleration and deceleration. (Uses car driving analogy accelerator and braking to decelerate) Generally these forces run along straight, linear pathways, in rebounding we manipulate them to travel vertically or straight up. This, along with the other forces of gravity and velocity variables introduces the physiology to a whole new environment it must adapt to.
Traditionally, working vertically can be eventually problematic as the only other modalities are basically running and sports which require many years of technique and are often difficult to reach high exertion levels due to the potential damage these activities are known for (i.e. knee, back & foot issues). Rebounding takes all that away due to the mat & spring system, allowing the user to reach high levels of output/exertion without the compounding damage of a hard surface.
An important part rebounding plays is working relatively unknown part of our physiology called the lymphatic system. The lymphatic system is a system of tubes that start in the toes and fingertips and work up throughout the entire body. It is filled with one way valves which makes it so the lymph fluid only flows in one direction. The lymphatic system is sometimes known as the internal vacuum cleaner of the body. It has the capability of sucking up toxins, poisons, trash and metabolic waste making it possible for the oxygen and nutrients to get in and bathe the cells. The way to turn on the lymphatic system is by activating the one way valves , and the way you activate those valves is by an “up and down” activity or vigorous movement. Rebounding is one of the most efficient ways of achieving this.
Because of the elevated lymphatic system activity, rebounding acts as a “cleansing” exercise which in our opinion places this style in a class of its own. The next key benefit of rebounding is the aerobic work, or the ability to breathe deeply and take in greater quantities of oxygen which has many profound and far reaching crossovers too many to list here. Next we come to the resistance, which comes in the form of gravity. Because gravity is an invisible force which passes through all 50 trillion cells of the body, each one of these must contract in order “keep the body together” so to speak (If a cluster of these cells were NOT to contract, they would float away in space and time!).
Training the body on a cellular level creates elevates effects such as the connective tissues and muscles become stronger and work as a compete unit, the vital organs get conditioned allowing them to function more efficiently due to the increased lymph fluid activity. We also get to stimulate the balancing mechanisms of the body; the vestibular system, the anti-gravity muscles and the proprioceptors of the joints, so that you develop a greater sense of balance, coordination, rhythm, timing dexterity, and kinaesthetic awareness. Because of all these benefits, we have found that the entire body will function much easier.
Point of the story, if you have a history of eating "garbage" food, your "garbage collectors" are regulated by the lymphatic system. The easiest way to stimulate this system into action is rebounding. What are you waiting for? Get bouncing!
