THE BENEFITS OF REBOUNDING

You may remember jumping on a trampoline as a kid as a fun activity, but did you know that trampolining can actually be an effective form of exercise? As you jump on a rebounder (mini trampoline) you experience a brief period of weightlessness. As you hit the mat, your body can experience up to 4Gs of gravitational force. A scientific study published in the Journal of Applied Physiology in 1980 researched the difference between treadmill running and trampoline jumping. Participants used a treadmill at different speeds and then jumped on a standard sized trampoline at four different heights to compare the difference between the two modes of exercise. What they found was surprising: • The G-force measured at the ankle was always more than double the G-force measured at the back and forehead while running on a treadmill. This helps to explain shin splints and knee problems. 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 shows that trampoline jumping makes it possible to exercise the entire body knowing that there is no undue pressure applied. • While trampolining, work output compared to oxygen uptake was significantly greater than running. This means that due to the opposing gravitational forces of jumping the body performs more work but with less energy expended, thus requiring less oxygen demand and less demand placed on the heart. This statement verifies the fact that rebound exercise is an excellent exercise for our senior citizens, those physically handicapped, those who are recuperating from an accident or injury, or anyone else who needs exercise but is hampered by a pre-existing physical condition. • This study also showed that rebounding can help rebuild lost bone tissue. NASA was interested in this study to help rebuild astronauts who had lost bone mass after time in space. The increased G force on the bones helps to strengthen them with less risk of injury than other forms of exercise. This can also be effective with those affected by osteoporosis. More recent research published in the German Journal of Sports Medicine in 2018 confirmed the effectiveness of

rebounding to improve fitness even when following a light workout schedule. The study had participants perform 3 workouts a week, each 19 minutes long, with variations in intensity. Although this workout regimen is far below the American Heart Association’s recommendation of 150 minutes per week, “significant improvements were found in aerobic capacity,” body fat was reduced by 5.4% and trunk strength was also significantly increased. A final study in 2016 by the International Journal of Sports Science showed a much greater increase in cardio strength (more than twice that of participants who jogged on treadmills) and reduction in body fat (50% greater than the jogging group) with workouts 3 times a week for 30-35 minutes. This shows that rebounding can be an alternative to other exercise to fulfill exercise recommendations. So how does rebounding help? • Protects the joints from the chronic impact delivered by exercising on hard surfaces • Strengthens the heart and other muscles in the body so that they work more efficiently. • Circulates more oxygen to the tissues. • Benefits the lymphatic circulation by stimulating the one-way valves of lymphatic system. This can benefit the body’s immune system to fight current disease, destroy cancer cells, and eliminating antigens to prevent future illness. • Improves coordination between proprioceptors in the joints, the transmission of nerve impulses to and from the brain, transmission of nerve impulses and responsiveness of the muscle fibers which improves balance, reflexes and our body’s ability to tell where it is in the dark or in open space. • Gradually improves resting metabolic rate so that more calories are burned for hours after exercise. • Promotes tissue repair. • Improves the brain’s responsiveness to the vestibular system in the inner ear, thus improving balance • As with other exercise, tends to slow atrophy (muscle wasting) as part of aging
