Hello, I just have one question about ossification process. One problem from Destroyer asks which would be true about the stress being placed on the bones after a marathon runner ran 100 miles in a race. The answer choice A was "Osteoclastic activity increases, and calcium phosphate is removed from the bone". The answer choice B was "Osteoblastic activity increases, and calcium phosphate is released into the matrix". The correct answer was B, but I do not see why answer choice A is wrong. I thought during the ossification, the bone first gets resorbed by osteoclasts, which break down the bone and increases calcium concentration in the blood, and then gets deposited by osteoblasts. Wouldn't putting a consistent force induce an osteoclastic activity first? Sorry if this is a dumb question but I haven't taken physiology yet so I am pretty ignorant on this subject. Thank you.
