FIGURE 3.

Chronic endurance training induces browning and increases the number of multilocular adipocytes in the SC Ing fat depot of LF- and HF-fed rats. Pictures of left and right SC Ing fat depots from Sed and Ex rats fed either a LF (A and B) or a HF (G and H) diet for 8 weeks. Samples of the upper extremities and middle regions of the SC Ing fat depots, as indicated by the black circles, were used for H&E staining and microscopy analyses. Representative images (×20 magnification) of adipocytes from Sed (C and D) and Ex (E and F) rats fed a LF diet or from Sed (I and J) and Ex (K and L) rats fed a HF diet are shown.
