#Logarithmic transformation for normality and comparison.
Body weight, epididymal fat mass, and the masses of gastrocnemius, quadriceps femoris, EDL and soleus muscles were measured at the end of the 19-week experiment. The muscle masses are average of both limbs. * = vs. LFsed (P < 0.05), ** = vs. LFsed (P < 0.01), *** = vs. LFsed (P < 0.001), §§§ = vs. HFsed (P<0.001), ¤¤¤ = vs. LFexe (P < 0.001). Results are means (±SD).
