Improves Bone Density

As we get older, we lose bone mass and mineral content which means they become frail and porous and that can lead to osteoporosis and other degenerative skeletal conditions. The cell in the body that is bone forming is known as “osteoblast”. Rebounding helps to promote osteoblastic activity thereby stimulating bone growth and restoring bone density.

Spaceflight osteopenia refers to the characteristic bone loss that occurs during spaceflight. NASA discovered that astronauts who went off into the weightless environment in space significantly lose a percentage of their bone density because there is no gravitational pull to positively stress their bones – Bone remodels in response to stress in order to maintain constant strain energy per bone mass throughout. To do this, bones become denser in areas experiencing high stress, while resorbing density in areas experiencing low stress. On the moon where gravity is about one-third that of earth, the gravitational forces acting on astronaut’s bodies would be much lower, causing bones to decrease in mass and density.

Rebounding has been used as an effective form of rehabilitation for astronauts.

Osteoporosis For those with Osteoporosis it is important that their workouts engage the body in a way that applies positive stress on the bones to stimulate growth, per Wolff’s Law states that bone grows and remodels in response to the forces that are placed upon it in a healthy person. The technical term for these bone stimulating forces is osteogenic loading. Exercise works on bones much like it works on muscles — by making them stronger. Because bone is a living tissue, it changes in response to the forces placed upon it. When you exercise regularly, your bone adapts by building more cells and becoming denser. The only issue is that higher impact weight bearing exercise needed for bone growth/repair can be very painful for people suffering from Osteoporosis. This is why Rebounding is a perfect exercise for these populations. It is weight bearing yet very low impact and kind on the joints and soft tissues. Rebounding improves strength, muscular development (which is crucial for bone development), balance, and coordination.  Rebounding engages the whole body and moves the whole body through space.


James Winfield, co-founder of Rebound Fitness shares his personal experience.

“I too suffer from Osteo-arthritis following years of playing high intensity, high impact sports such as soccer, tennis and running. These activities are no longer an option for me. Finding Rebound exercise has been like a “prayer answered” for me as I can still enjoy high intensity exercise but with very little impact on my joints and know that every bounce is building bone mass and preserving my joints rather than damaging them.”

Remember every we are all different and degrees of bone disease vary in severity so DO NOT JUMP if you have less than a -3.0 T-score in the spine or hip!

Rebounding can be used both as a preventative measure, and as relief for those already suffering from these conditions.
