Already in 1980, NASA published that Rebounding strengthens the bones and increased bone density.
Our customers experienced that with ten minutes of daily rebounding, their bone density came back to normal and reversed their Osteopenia within one and a half years.
In Germany, medical studies done by the "Board for Preventive Medicine" have shown that Rebounding can stop the decrease of bone density due to Osteoporosis. The following video clips document those studies:
Better bones #1
Better bones #2
One study found that even a single bout of high-impact exercise can increase bone turnover. Study participants jumped up and down until they were exhausted. Afterwards, markers of bone formation (procollagen type I amino terminal propeptide [P1NP] and bone resorption (carboxyterminal crosslinked telopeptide [CTx]) were both elevated, signifying that the body was busily fixing the damage and rebuilding the bones to be stronger.
