The relationships of aerobic exercise and cognitive function have been extensively examined in recent studies. Some of current research indicated that acute aerobic exercise can improve the cognition, including inhibition, emotional modulation, and error monitoring. Violent behavior is a consequence from the interaction of inborn factors and acquired environmental factors. Problems of cognition could explain the behavior of violent offenders. Purposes: First, to examine whether acute exercise can influence inhibitory control; second, to examine whether acute exercise can influence emotional modulation; third, to examine whether acute exercise can influence error monitoring. Methods: 16 violent offenders (mean age: 32.81±9.85), 14 non-violent offenders (mean age: 31.00±7.28), and 15 healthy-controls (mean age: 22.73±2.31) were recruited in the current study. Participants were asked to perform an emotional stop signal task under go, and stop with neutral and negative conditions after 30min exercise which were set as acute moderate aerobic exercise intervention, and a control session which were set as reading exercise-related books. While measuring task performance, the behavior data (i.e. go accuracy, go reaction time, stop error rate, stop signal reaction time (SSRT), and post-error slowing (pES)), and ERPs component, comprise P3, N2, LPP, and ERN were collected concurrently. Results: First, the SSRT was decreased in three groups after the exercise session but not the reading session and the pES of the violent group was lower than controls after the exercise session. Second, violent group had an increased P3 amplitude than the non-violent offender group after the exercise session. However, there were no differences on N2, LPP, and ERN amplitude after exercise. The current study suggests the ability of inhibitory control in 3 groups can be facilitated by acute exercise intervention, but the error monitoring process and the subsequent process of regulate in the violent group was disrupted by exercise. Finally, considering the particularity of our subjects, it would suggest the exercise intervention may have different effects in different subjects. It remains necessary to investigate whether different kinds of exercise or different intervention can influence violent offenders. Furthermore, this study also suggests that exercise may be able to be an auxiliary intervention in addition to education and counseling.
