Figures & data
Fig. 1 High hydroxytyrosol intake becomes pro-oxidant in exercised rats. Weight gain (A) and feed efficiency (B) reported throughout the study. Hydroperoxides (C) were quantified in plasma at the end of the study. a p < 0.05 compared with the sedentary group. b p < 0.05 compared with the EXE group. c p < 0.05 compared with the SED group. SED, sedentary; EXE, exercised; 20, group supplemented with 20 mg/kg/d of hydroxytyrosol; 300, group supplemented with 300 mg/kg/d of hydroxytyrosol
Fig. 2 Mitochondrial organic Hydroperoxides. No statistical differences were found for mitochondrial organic hydroperoxides, SED, sedentary; EXE exercised; EXE20, group supplemented with 20 mg/kg/d of hydroxytyrosol; EXE300, group supplemented with 300 mg/kg/d of hydroxytyrosol

Fig. 3 Maximal velocity performance is influenced by hydroxytyrosol. Maximal velocity tests in sedentary rats (A) were performed prior to and at the end of the study. The maximal velocity test in exercised animals (B) was performed before the study, after 5 weeks and at the end of the study. a p < 0.05 compared to Test 1. b p < 0.05 compared to Test 2. c p < 0.05 compared to the SED20 group in Test 3. SED, sedentary; EXE, exercised; 20, group supplemented with 20 mg/kg/d of hydroxytyrosol; 300, group supplemented with 300 mg/kg/d of hydroxytyrosol
Fig. 4 Hydroxytyrosol affects physical work performed during the training protocol. Total work (A) and mesocycle work (B). a p < 0.05 compared to the EXE20 group. b p < 0.05 compared to MES1. EXE, exercised; EXE20, EXE supplemented with20 mg/kg/d of hydroxytyrosol; EXE300, EXE supplemented with300 mg/kg/d of hydroxytyrosol; MES, mesocycle
