The results showed the followings: (1) in terms of behavior, there was no significant difference between different intensities of acute aerobic exercise, both reduced the response time of the Stroop effect significantly; (2) in terms of nerve, there was a difference between the testees in the two groups, the [HbO] of the right DLPFC of the testees in the medium intensity group was significantly higher than that of the testees in the high intensity group; while the [HbO] of the left DLPFC and the right VLPFC of the testees in the high intensity group increased significantly after exercise intervention. Conclusions: 30min medium and high intensity aerobic exercise can improve the task performance of execution control of MA addicts, but high intensity aerobic exercise brought the activity enhancement of more prefrontal cortex (including the left DLPFC and the right VLPFC). It was speculated that high intensity acute aerobic exercise is more conducive to MS addiction individuals recovering their execution control ability.
