How does an extensive exercise program affect the appearance of the skeleton? Why do these changes occur?

What will be an ideal response?


Exercise causes the muscles to pull on the bones to create movement, and the greater the amount of movement, the greater the overall tension exerted on the bone. Tension on a bone causes it to build additional compact bone at that spot; therefore, bones of individuals who increase the amount of exercise they perform become more dense and have larger processes.
