Background:  The increasing of age, inflammatory factors¸ and metabolic syndrome are the effective reasons in the reduction of  brain volume. The aim of this research was to investigate the effect of twelve week aerobic exercise with moderate intensity on IL1β, IL-6, and brain volume in 50-65 years old women with metabolic  syndrome.
Materials and Methods: 24 women with Metabolic Syndrome (MetS) took a part voluntarily. They were divided into two groups, MetS exercise (EM), MetS control (CM). ME group participated in an aerobic exercise training (AT) program (for 12 weeks), three sessions per week, each session contained three performing parts and two relaxing parts, at the beginning, each part contained eight minutes. Also each week, one minute added to performing sets. MRI and blood samples were conducted before and after three month to evaluate the levels of IL1β, IL-6, and brain volume. Data were analyzed by paired-sample of T-Test, and independent samples of T-Test.
Results: Brain volume afterthree  month doesn't significantly changed, but IL1β, and IL-6 after tree month exercise were significantly decreased (P<0.05). Also, there were not significantly different in brain volume, IL1β, and IL-6 pre and post test in the control group.
Conclusion: These findings indicate that three months aerobic exercise with a moderate intensity ameliorate inflammatory factor and doesn't change brain volume. Maybe with adjusting, the time and intensity of exercise brain volume will be increased.

Materials and Methods: A number of 45 patients with CABGwere assigned to three groups: control (n=12), aerobic exercise (n=15), and resistance training (n=18). Three aerobic and resistance training sessions were performed per week for eight weeks. Anthropometric variables, expression of ABCG4 gen, as well as the serum levels of Apo-A and Apo-B, were measured before and after the training period. Data were analyzed using repeated measures of ANOVA. A p-value less than 0.05 was considered statistically significant.

Results: Aerobic and resistance training significantly increased the expression of ABCG4 gene, compared to those in the control group (P=0.001); nonetheless, there was no significant difference between the two training groups (P= 0.021). Significant differences were observed in serum levels of Apo-A and Apo-B in both aerobic and resistance training groups, compared to those obtained in the control group (P=0.001). However, the difference between aerobic and resistance training groups was significant for Apo-A (P= 0.001), but not for Apo-B (P=1.000). Moreover, the ratio of Apo-A to Apo-B was significantly different for the resistance training group, compared to that in the control group (P= 0.001); nevertheless, it was not significant for the aerobic training group (P=1.000).
Conclusion: As evidenced by the results of this study, resistance training improves cholesterol reverse transport regulators more than aerobic training; therefore, resistance training is recommended to regulate reverse cholesterol transfer.
