Abstract
Fatigue is one of the most common symptoms among individuals with multiple sclerosis (MS). The imbalance of inflammatory cytokines in the brain causes mental fatigue. It is believed that aerobic exercise may moderate the level of inflammation of cytokines and thus reduce mental fatigue. This study was conducted to investigate the effect of swimming aerobic training on pro-inflammatory factors (interleukin 6) and anti-inflammatory factors (interleukin 10) to evaluate mental fatigue in the brains of female mice after EAE induction. In this research, 21 mice (8 weeks old, 18 to 20 grams) were divided into three groups: healthy control, EAE control, and EAE swimming aerobic exercise. The animals in the training group performed moderate-intensity swimming exercises for 4 weeks, with 5 sessions per week, each session lasting 30 minutes. The western blot method was used to analyze the research variables. The results showed no significant difference in the amount of IL-6 between the EAE group and the swimming training group, but the amount of IL-10 in the swimming training group showed a significant increase compared to the EAE group. The ratio of IL-10/IL-6 values between the swimming training group and the EAE group was also not significant. It seems that moderate-intensity swimming aerobic exercises, without changing the pro-inflammatory factor, along with increasing the anti-inflammatory factor IL-10, can lead to an improvement in the balance of the inflammatory index and a reduction in fatigue in the EAE group and the swimming exercise group.

Abstract
Introduction:Disruption of the homeostasis of immune regulatory mediators Aryl hydrocarbon receptor (AhR) and Ornithine decarboxylase-1(ODC-1) is involved in the pathogenesis of multiple sclerosis (MS). Physical activities play a role in controlling and improving the symptoms of MS. This study aimed to investigate the effect of 4 weeks of physical activity in enriched movement environment on the gene expression of AhR and ODC-1 in the cerebellum tissue of an MS mice model.
Method: This experimental study was conducted on 30 female C57BL/6 mice (age: 8 weeks and average weight: 18 ± 2). Mice were divided into 3 groups of 10 including 1) healthy control, 2) Induction of experimental autoimmune encephalomyelitis (EAE) and 3) EAE + physical activity in enriched movement environment for 4 weeks. Clinical score were recorded daily from induction until 28 days. The gene expression of AhR and ODC-1 in the cerebellum was measured by RT-PCR method. Statistical analysis of the data was performed using one-way analysis of variance.
Results: Activity in the enriched movement environment significantly decreased the gene expression of AhR compared to the EAE group (P=0/02) and also decreased the gene expression of ODC-1, but it was not statistically significant (P=0/28). Also, the clinical score improved significantly after activity in the enriched movement environment (P= 0/001).
Conclusion: In general, it seems that lifestyle change and activity in enriched movement environment lead to the down regulation of the gene expression of AhR and ODC-1 in the cerebellum and improved the clinical score of animals with MS.
