Abstract: Objective: To study the characteristics of effective connectivity (EC) in female methamphetamine (METH) addicts and the intervention effect of 12-week aerobic training on addiction thirst, mood, and brain EC in addicts. Methods: The subjects were randomly divided into control group (CON group), METH addict group (METH group) and METH addict exercise group (METH-Ex group). Functional near-infrared spectroscopy (fNIRS) was used to collect cerebral blood oxygen signals. Sleep, depression, anxiety and thirst in subjects were assessed respectively by PSQI, SDS, SAS and DSQ scales. Both the METH group and the CON group received resting and exercise tests, and the METH-Ex group received a 12-week aerobic kickboxing training intervention of moderate intensity, and resting cerebral oxygenation tests, and mood and craving assessments were performed at 1st, 6th and 12th week. The cerebral blood oxygen signal data were transformed by Bayesian inference, the EC was tested according to Shapiro-Wilk, and data were analyzed by repeated measures ANOVA using SPSS 20.0. Results: There was a significant interaction between METH addiction and aerobic kickboxing exercise intervention on brain EC between LPFC-LMC, RPFC-LMC. The intensity of brain EC coupling in the resting METH group was significantly lower in LPFC-RPFC and LPFC-RMC than in the CON group; the intensity of brain EC coupling in the METH-Ex group was significantly lower in LPFC-RPFC, RPFC-LPFC, LPFC-LMC, LPFC-RMC, RPFC-LMC, RPFC-RMC, LMC-RMC than in the CON group, and RPE-Ex was negatively and significantly correlated with EC levels in LPFC-RPRC, RPFC-LPFC. Results of 12-week aerobic kickboxing exercise intervention in SDS, SAS, and DSQ groups were significantly different (P<0.01), and the level of depression, anxiety, and craving in subjects decreased significantly. The intensity of brain EC coupling in the METH-Ex group decreased significantly in LPFC-RPFC and RPFC-LPFC, while the intensity of brain EC coupling in LMC-RMC, LMC-LPFC, LPFC-RMC, RPFC-RMC, RMC-RPFC showed an increasing trend after the experiment. SDS had a significant moderate intensity correlation with the EC level of LMC-LPFC and LMC-RPFC, and SAS had a significant moderate intensity correlation with LPFC- RPFC, and DSQ showed a weak correlation with LPFC-RPFC and RPFC-LPFC. Conclusion: Brain EC in female METH addicts is lower than that in normal females, a single aerobic exercise intervention tends to reduce the EC level of METH addicts in exercise state, and RPE scale score is negatively correlated with EC change after the aerobic intervention; EC level in female METH addicts shows a decrease-increase trend after continuous aerobic kickboxing exercise intervention, indicating that long-term exercise intervention may have better effect on female METH addicts; aerobic kickboxing exercise intervention significantly lowers the level of depression, anxiety and METH craving in female METH addicts, and these changes are correlated with the EC between some cerebral regions.
