Bone tissue adaptations to resistance training
In response to loading of the bone, created by muscular contractions or other methods of mechanical forces, the bone begins a process of bone modeling which involves the manufacture of protein molecules that are deposited in the spaces between bone cells. This leads to the creation of a bone matrix which ultimately becomes mineralized as calcium phosphate crystals, resulting in the bone acquiring its rigid structure. This new bone formation occurs chiefly on the outer surface of the bone, or periosteum.
