2) Hyaline cartilage thickens which helps to cushion joints, therefore protecting the bones from wear and tear.
3) Flexibility and mobility training may slightly stretch ligaments, allowing a greater range of movement at the joint.
4) Bone has the ability to alter its strength in response to mechanical stress. by the process of bone formation and resorbsion, there is increased disposition of minerals and increased formation of collegen fibres.
Both contribute to increased bone
