E+S= Exercise + Supplement; E= Exercise; S= Supplement; Con= Control; CfB = Change from Baseline; PTH= Parathyroid Hormone; CT= Calcitonin; Ca+2= Ionized Calcium. Superscripts denote significantly differences among the groups.
† p < 0.05, significantly different from baseline values (within groups, baseline vs. week 16).
