Seventeen young Chinese policemen as participants have taken part in the physical fitness standard assessment, Stroop test of word meaning and word color as well as the pretest and posttest of ERPs experiment. The exercise frequency was on alternative days for 80 min every time. Exercise helped to improve physical ability and VO 2 peak for policemen. BMI and heart rates during rest deceased. The N2 results showed the main effect of the stimuli type or exercise interference was significant, but there was no significant interaction between stimuli type and interference.
