Abstract In preclinical models, exercise training ET or pomegranate juice PJ individually prevents prostate cancer progression. Here, we hypothesize that physical exercise combined with antioxidants could induce synergistic effects through oxidative stress modulation. Forty male Copenhagen rats with prostate tumors were divided into four groups: Control, PJ, ET, PJ+ET. Rats from PJ group consumed daily 750 μl of PJ, rats from ET group run on a treadmill 5 days per week and PJ+ET rats received the combined treatments. Each week, tumor growth was evaluated. After four weeks of treatment, rats were euthanized and blood, muscles and tumors were collected. Tumor Ki67, Extracellular signalRegulated Kinase ERK activation, Bcl2 expression, enzymatic and non-enzymatic antioxidant defenses as well as oxidative stress markers (oxidized base, lipid peroxidation, protein carbonylation) were measured. PJ or ET significantly decreased prostate tumor proliferation (Ki67 staining, p
