I wonder though about those of us who also tour for long distances or do things like centuries. Probably wouldn't be a bad idea to incorporate some weight lifting or at least some extra calcium into the mix.
Thanks for posting this. The exercises which counteract osteoporosis (thin bones) must involve working against gravity. Hence, swimming and biking do not do anything to help with bone density but running does.
It is interesting since cyclists develop incredibly muscular legs and one would think intuitively that this would put stress on the bones and help bone density but this is not the case.....Interesting why it needs to be against gravity.......
Do you remember when that cyclist crashed with Lance (not the final tour he won) and broke his femur? Was it Ivan Baso (sp)? The femur is the strongest bone.........takes a big mechanical force or a weak bone to cause such fracture. Though I don't know his bone density my guess would be that he has osteoporosis.......the crash was not that big, IMHO.........
