Diet (D); exercise (E), diet x exercise interaction (DxE); sedentary rats (SED); trained rats (T); trained and exhausted rats (TE); reference diet (REF); cocoa diet (C10); cocoa and hesperidin diet (CH). Data are expressed as mean ± SEM (n = 6–8/group). Statistical differences indicated in the legend box; when the DxE interaction was significant: * p < 0.05 vs. REF diet, # p < 0.05 vs. C10 diet; NS, no statistically significant differences.
