The objective of this study was to analyze the magnitude of the inflammatory response induced by a high number of eccentric actions (AE) of the elbow flexors. Participated on this study nine young men who performed 35 sets of six AE of the elbow flexors, with an one minute interval, using an isokinetic dynamometer at 210º.s-1. Maximum voluntary isometric contraction (MVIC), range of motion (ROM), delayed onset muscle soreness (DOMS), interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-α) were measured. Significant changes were observed for markers of muscle damage (MVIC, ROM and DOMS), however, there were no changes on inflammatory markers IL-6 and TNF-α. In conclusion, the results show that even with large numbers of AE and changes in indirect markers of muscle damage, no change was observed in the systemic inflammatory response.Downloads
