Plasma malondialdehyde concentration 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 and p < 0.01 espectively; a: significant difference when compared to the anaerobic exercise; b: significant difference when compared to the combined (anaerobic and aerobic) exercise.
