Forces in the body

For comparison: Hitting the ground with straight leg, a force equal to typically 2 or 3 times body weight is generated. In this case, however, there is no leverage, so that the same force acts on the bone. This simple example shows that, normally, the contribution of muscle forces on bone is significantly larger than external forces.

The peak forces described above in a healthy fit subject result in a deformation of bone between 1000 µStrain and 2000 µStrain. In a tibia length (shin-bone length) of about 40 cm this corresponds to a deformation between 0.4 mm and 0.8 mm. This shows the magnitude of the impact of everyday movements in bone strength.

This fact makes it clear that appropriate daily exercise is needed to avoid bone resorption. Targeted Galileo Training can help prevent this bone loss.
