Broadband Ultrsonic Attenuation (BUA) and velocit y of sound (VOS), bone formation marker Osteocalcin (OSTN) and bone resorption m arkers urinary Pyridum crosslinks (PYR and D-PYR) were studied before and after four months of Tai Ji exercise. Improved bone structure and increased bone dens ity in menopausal women were reflected by BUA results. The increased BUA appear s to be associated with increased bone formation rather than decreased bone reso rption.展开更多
