A good point has been brought.
As widely known,exercise promotes bone mass growth (this includes running,martial arts or weightlifting as a very effective method.It has to involve resistance) Only sport I can think of which does not do nearly anything to your bones according to statistics is swimming.
That aikido example is a nice one,I have not heard of that shin growth thing personally but Iīve heard a funny note on "freaky thick wrists" of aikido instructors due to constant repetition of grabbing movements such as wrist grab escapes and all.
