The body has a built-in need for activation. The lymph system, for example, bathes every cell, carrying nutrients to the cell and waste products away. Yet the lymph is totally dependent on physical exercise to move.
Without adequate movement, the cells are left stewing in their own waste products and starving for nutrients, a situation that contributes to arthritis, cancer and other degenerative diseases. Vigorous exercise such as rebounding [jumping on a therapeutic mini-trampoline] is reported to increase lymph flow by 15 to 30 times. Also, bones become stronger with exercise.
Vertical motion workouts such as rebounding are much different and much more beneficial and efficient than horizontal motion workouts, such as jogging or running.
The lymph fluid moves through channels called “vessels” that are filled with one-way valves, so it always moves in the same direction. The main lymph vessels run up the legs, up the arms and up the torso. This is why the vertical up-and-down movement of rebounding is so effective to pump the lymph.
Rebounding For Detoxification And Immune System Benefits
The rebounding motion stimulates all internal organs, moves the cerebral-spinal fluid and the aqueous fluid within the eyes (many people claim improved eyesight), and does wonders for the intestines. Many immune cells such as T-lymphocytes and macrophages are self-propelled by amoebic action. These cells contain molecules identical to those in muscle tissue. All cells in the body become stronger in response to the increased G-force during rebounding, and this cellular exercise results in the self-propelled immune cells being up to five times more active. The job description of these cells includes eating viruses, bacteria and even cancer cells, so it is good that they be active. This exercise directly strengthens the immune system.
Rebounding is an exercise that reduces your body fat; firms your legs, thighs, abdomen, arms, and hips; increases your agility; and improves your sense of balance. Rebounding strengthens your muscles overall, provides an aerobic effect for your heart, rejuvenates your body when it’s tired, and generally puts you in a state of health and fitness.
Jumping on a rebounder is remarkably gentle on the joints. There’s no solid ground to suddenly stop the bouncing of your feet. Your movements are perfectly safe, and they make the effect of gravity beneficial.
Some benefits of rebounding include:
• 20 minutes of rebounding = 1 hour of running for cardiovascular workout
• Easy on the bones and joints (when using a therapeutic rebounder)
• Rebounding strengthens the heart muscle
• Profound body detoxification is possible
By working against constant gravitational pressure while bouncing, you resist Earth’s pull. Your resistance is subtle, but it builds cellular strength. Rebounding’s alternating weightlessness and double gravity produce a pumping action that pulls out waste products from the cells and forces into them oxygen and nutrition from the bloodstream.
The Detoxification Effect of Rebounding
The lymphatic system is the metabolic garbage can of the body. It rids you of toxins such as dead and cancerous cells, nitrogenous wastes, infectious viruses, heavy metals, and other assorted junk cast off by the cells. The movement performed in rebounding provides the stimulus for a free-flowing system that drains away these potential poisons.
Unlike the arterial system, the lymphatic system does not have its own pump. It has no heart muscle to move the fluid around through its lymph vessels. There are just three ways to activate the flow of lymph away from the tissues it serves and back into the main pulmonary circulation. Lymphatic flow requires muscular contraction from exercise and movement, gravitational pressure, and internal massage to the valves of lymph ducts. Rebounding supplies all three methods of removing waste products from the cells and from the body.
The Muscular Effect of Rebounding
James White, Ph.D., director of research and rehabilitation in the physical education department at the University of California at San Diego (UCSD), has explained how jumping for health offers a true physical strengthening effect to the muscles.
“Rebounding allows the muscles to go through the full range of motion at equal force. It helps people learn to shift their weight properly and to be aware of body positions and balance,” says White.
An advocate of rebounding for athletic conditioning, White uses the rebounder in his rehabilitation program at UCSD. “When you jump, jog, and twist on this [jumping] device, you can exercise for hours without getting tired. It’s great practice for skiing, it improves your tennis stroke, and it’s a good way to burn off calories and lose weight,” says White.
“My students tell me it’s so much fun that they often exercise on the rebounders for their own enjoyment.”
White adds that jumping for health is more effective for fitness and weight loss than cycling, running or jogging, and it has the added advantage of producing fewer injuries.
The gentle bounce of rebounding is effective in returning natural, regular bowel movements to chronically constipated persons. The steady bounce sets up a pulsating rhythm transmitted by the nervous system to the brain area responsible for regulating the intestinal system, which reestablishes one’s rhythmical bowel activity. Digestion is improved as well.
It is important to realize that as you age, your body may become more toxic due to the pollutants in today’s world. It is also important to realize that if you have a disease, your cellular structure is compromised, as your cells are already being robbed of the correct oxygen, mineral and nutrient compounds that they need to stay healthy.
Rebounding is beneficial, but other commonsense health practices are also important to maximize health and well-being.
