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. The present 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 brain of female mice after EAE induction. In this research, 21 mice (8 weeks old, 18 to 20 grams) were divided into 3 groups: healthy control, EAE control, and EAE swimming aerobic exercise. The animals in the training group performed moderate-intensity swimming exercises for 4 weeks, 5 sessions per week, 30 minutes per session. The western blot method was used to analyze the research variables. One-way analysis of variance and Tukey's post hoc test were used for statistical analysis. The results showed that there was no significant difference in the amount of IL-6 between the EAE group and swimming training, but the amount of IL10 in the swimming training group showed a significant increase compared to the EAE group. However, the ratio of IL 10/IL 6 values between the swimming training group with EAE was also not significant. It seems that moderate-intensity swimming aerobic exercises, without change in the pro-inflammatory factor, along with driving towards anti-inflammatory factors, with an increase in IL10, can lead to an improvement in the balance of the inflammatory index and a reduction in fatigue between the EAE group and swimming exercise.
