Summary of the effects of exercise training on the abundance/activity of antioxidant enzymes in skeletal muscle. SOD (total) = superoxide dismutase 1 + superoxide dismutase 2; SOD1 = superoxide dismutase 1; SOD2 = superoxide dismutase 2; GPX (total) = all glutathione peroxidase isoforms in fiber; GPX1 = glutathione peroxidase 1; CAT = catalase; Trx1 = Thioredoxin 1; PRDX5 = Peroxiredoxin 5 = PRDX5. Arrows signify exercise-induced increases in antioxidant activity. Question marks (?) indicate that it remains unknown as to whether exercise increases the activity of select antioxidants.
