Superoxide dismutase (panel A), plasma glutathione peroxidase (panel B), and glutathione reductase (panel C) content before (Rest), immediately after (P0), and 5 (P5), 10 (P10), and 20 (P20) min after aerobic, anaerobic, and combined (anaerobic and aerobic) exercise. Data are expressed as the % change from pre-exercise resting concentrations. *, **, ***: significant difference when compared to pre-test values at the level of p < 0.05, p < 0.01 and p < 0.001 respectively; a: significant difference when compared to the aerobic exercise; b: significant difference compared to the combined (anaerobic and aerobic) exercise.
