Acute effects of physical exercises on the inflammatory markers of patients with fibromyalgia syndrome: A systematic review

We suggest that patients with FM probably have low-grade chronic inflammation, because studies found higher concentrations of IL-8 and TNF-α and high expression of IL-10 in these patients; however, the effects of exercise on the inflammatory markers in these patients are unclear. Although more research is needed on the effect of exercise on inflammation, none of the studies reported worsening of symptoms with exercise recommended as treatment.
