Objective(s): Although recent investigations have shown chronic
inflammation and inflammation-associated diseases might be ameliorated
by exercise; little is known about the relation between exercise
training with anti/pro-inflammatory cytokines.
Materials and Methods: This cross sectional study was conducted to
compare interleukin-4 (IL-4), IL-6, IL-10, IL-12, IL-13, interferon
gamma (IFN-gamma) levels in serum, and their in vitro production by
whole blood (WB) cells and by peripheral blood mononuclear cells (PBMCs)
in response to mitogens lipopolysaccharide and phytohemagglutinin.
Twelve elite wrestlers with history of three times per week exercise
training for about 9.5 years, and thirteen healthy silent controls were
recruited. To analysis the cytokines by enzyme linked immunosorbent
assay (ELISA), the blood samples were taken 24 hr after the last
training session from the wrestlers.
Results: Serum analysis for IL-4, IL-6, IL-10, IL-12, IL-13 and
IFN-gamma indicated no statistical difference between the two groups.
Meanwhile, 48 hr in vitro activation of WB and PBMCs by the mitogens
revealed that IL-6 production was elevated in both WB and PBMCs.
Whereas, IL-12 and IL-13 were decreased in supernatant of PBMCs and WB
cells cultures, respectively.
Conclusion: It seems that wrestling cause immune system cells to produce
anti-inflammatory myokine IL-6 and decrease production of
pro-inflammatory cytokine IL-12 and IL-13.
