Optical density on resorcin-fuchsin-stained segments. The optical density was significantly lower in sedentary and trained female animals than in control male rats. The OD was significantly reduced in trained male animals compared to sedentary male animals. (F_between groups = 11.911, df_between groups = 3, P_{between groups} = < 0.001). One-way ANOVA with post hoc Tukey’s test. Values are the means ± SEM. *P < 0.05 vs. MSE
