Antioxidant enzymes, a superoxide dismutase (SOD); b catalase (CAT); and c glutathione peroxidase assay (GSH-Px) in the liver. The experimental animals were divided into four groups: ND-UNT (normal diet untrained; n = 6), HFD-UNT (high-fat diet untrained; n = 6), HFD-MICT (high-fat diet + moderate-intensity continuous training; n = 6) and HFD-HIIT (high-fat diet + high-intensity interval training; n = 6). The data are presented as mean ± SEM and were compared between groups by one-way analysis of variance (ANOVA) with post hoc Duncan. ***p < 0.001; **p < 0.01; *p < 0.05 vs ND-UNT; ^## p < 0.01 vs HFD-UNT; ⁺⁺ p < 0.01 vs HFD-MICT
