FIGURE 9.

Representative cross-sections of liver, with haematoxylin and eosin staining at 10× magnifications for CHOW untrained (A), high-fat fed untrained (B), high-fat fed after endurance training (HFD+END; C), and high-fat fed after high-intensity interval training (HFD+HIIT; D). The effects of high-fat diet are clearly shown in (B) with the presence of lipid droplets, whereas both exercise programs induce a reduction in this finding. Since no major differences were seen in CHOW mice after exercise training, those images are not shown. The size bars indicate 100 μm and images are at 10× magnification.
