The annual changes of BMD at different anatomic sites measured by pQCT and DXA in the control group (CON) and the TCC exercise group (values are mean ± SD). Multivariance analysis for combined evaluation of DXA and pQCT measurements shows a significantly decelerated rate of bone loss at multiskeletal sites in the TCC group as compared with the control group (P<.05). When BMD was separately evaluated, only pQCT data showed significant deceleration of rate of bone loss in the TCC group as compared with the control group.
