Acute Pro-inflammatory Immune Response Following Different Resistance Exercise Protocols in Trained Men
… TNF?, MCP-1, and expression of CCR2, CD11b, and GCR on CD14++CD16- monocytes were similar following HVY and VOL. When collapsed across groups, TNF? was significantly increased at IP, 30P, 1H and 2H post-exercise (p = 0.001 – 0.004), while MCP-1 was significantly elevated at all post-exercise time …
