Over time heavy impact work increases the activity
of osteoblasts within your body which in turn leads to bigger and stronger bones — now this might not be something you've considered but when you get to middle aged, or elderly, and you fall over you might find yourself thankful for your years of pumping iron as you will likely walk away far less injured then your more sedentary friends.

within the bone marrow
of mice with lung tumors compared with cancer - free animals; and reducing the number
of osteoblasts in mice not only limited neutrophil infiltration
of tumors but also interrupted tumor progression.
«Our experiments showed that restoring H19 expression hindered by too much p53 restored «protective differentiation»

The Opotowski team, which found that low vitamin A levels had as great an effect lowering BMD as did high vitamin A levels, suggested that vitamin A deficiency may contribute to increased fracture risk by allowing bone matrix to grow faster than it can be mineralized.12 Indeed, although the net effect
of vitamin A is to stimulate osteoclasts and slow the growth
of osteoblasts, vitamin A also causes
osteoblasts to secrete a variety
of enzymes and other proteins that are important to bone mineralization, including osteocalcin, which is a protein that plays a direct role in attracting and binding calcium
within the bone matrix.6 By slowing the growth
of the matrix but increasing the rate at which it is mineralized, adequate vitamin A helps to ensure sufficient bone density.
