How to Prevent Osteoporosis Page 2 | ThirdAge: "Proof positive that a sedentary lifestyle is the enemy of your bones is that when an arm or leg is in a cast, or when astronauts experience zero gravity, or when someone is bedridden, a phenomenon called skeletal unloading comes into play. If this goes on for weeks at a time, the number of bone cells plummets, the transfer into the bones of vital nutrients such as calcium and phosphorous slows down, and osteoprogenitor cells that can create new bone are not produced as rapidly. In a less dramatic but still detrimental way, your bones begin to deteriorate when you spend too much time sitting and not enough time moving."
