<i>In vivo</i> areal bone mineral density.

<p>Analysis of the areal bone mineral densitometry (aBMD) by dual-energy X-ray absorptiometry (DXA) of the femurs of female rats with 6-months of age (initial) and after 21 days (final). The control rats group (CON) moved freely through the box during the experimental period and the hindlimb unloading rats group (HLU) were suspended for 21 days. Each column represents mean ± standard deviation (SD). Statistical analysis was performed with Wilcoxon test for intra-group analysis at the beginning and end of the experimental period (<i>P</i> < 0.05) and Mann Whitney test to compare the HLU group to the CON group * (<i>P</i> < 0.05). Animals number = 10/group.
