The Effects of 8-Week Combined Exercise Training on Inflammatory Markers in Women with Multiple Sclerosis.

The present study was designed to investigate the effects of 8-week combined endurance, resistance, and balance exercise training on IL-6, CRP, and IL-10 concentrations in women with multiple sclerosis. Thirty participants with multiple sclerosis (Expanded Disability Status Scale ≤6) were randomized into either an exercise and control groups. The exercise group performed 8-weeks of endurance, resistance, and balance exercise training. Serum concentrations of IL-6, CRP, and IL-10 were measured before and after the 8-week intervention. Moreover, anthropometric measures were determined at the onset of and after the intervention. For within- and between groups comparisons of all variables, t test (independent and dependent) was used (p < 0.05). The results revealed that IL-6 and CRP levels significantly decreased after exercise training (from 6.8 ± 1.52 to 3.2 ± 0.96, p < 0.001 and from 2.76 ± 0.98 to 1.55 ± 0.44, p = <0.001; respectively). Also, exercise training significantly increased IL-10 in the exercise group (from 16.4 ± 2.74 to 23.2 ± 2.11, p < 0.001). There was a significant difference between the 2 groups in all markers in the after 8-week exercise (p < 0.05). One of the characteristics of MS disease is inflammation. Exercise training through physiological mechanisms and without aggravating the inflammatory pathology can be effective in functional and symptom reduction of patients with MS. In confirmation of this, the present study showed that 8 weeks of combined exercise training decreased pro-inflammatory markers (IL-6 and CRP) and increased anti-inflammatory cytokine (IL-10). Our findings suggested that an exercise training program can be an effective strategy for managing the immune system of women with MS at least by its significant effect on inflammatory markers.
