Can physical exertion cause the bones to stretch and change?
gross bony structure change is not possible.
Well, the answer to your query is: No, as our body is specifically built and designed in such a way that it can withstand as well as adapt to such physical exertion.
To some extent, muscular hypertrophy (muscle growth and increase in size), joint space alterations can happen (that too after daily and excessive physical strenuous activities for a prolonged period), but the gross bony structures, position, and depth changes aren't possible.
Hope I have answered your query.
