Normalized SUVs (NSUV) of ¹⁸ F-FDG in hind limb muscle (HL). Data was collected over a 14-16 week period from age 6 to 20-22 in exercised w.t. (W.T.-Ex), non-exercised mdx (MDX-N.E.), exercised mdx (MDX-Ex) and non-exercised udx (UDX-N.E.) mice. Plotted values are means and standard deviations of normalized SUV of surviving mice 23 from each group. Significant differences (p<0.05) are observed at week 8 and 20 between: W.T.-Ex and UDX –N.E. (ψ), MDX-Ex and UDX-N.E.(π), and MDX-N.E and UDX-N.E. (_); and, at week 4 between: W.T.-Ex and MDX-Ex (*), and MDX-N.E. and MDX-Ex (φ).
