Figure 1: Trabecular and cortical bone microarchitectures at the left femurs of Wistar female rats. The rats in O groups were ovariectomized. Rats in E groups were submitted to 10 free-fall impact exercise per day, 5 days a week during 8 weeks. Rats in Sr groups received 625 mg/kg/day of SrRan. The critical p-value were p = 0.05: *, p < 0.01: **, p < 0.001: ***, NS: non significant and a: vs Sh, b: vs ShE, c: vs ShSr, d: vs ShESr, e: vs O, f: vs OE, g: vs OSr and h: vs OESr.
