The extracellular matrix (ECM) in skeletal muscle plays an integral role in tissue development, structural support, and force transmission. Upon mechanical loading, including resistance exercise, which alter muscle fiber contractile activity, size, orientation and connectivity, remodeling processes must occur that involve both ECM deposition and degradation. ECM remodeling involves many cell types in muscle, but the focus of our research was directed towards macrophages, which participate in the early immune response to damage and loading. We have consistently demonstrated a significant increase in skeletal muscle macrophage abundance using pan macrophage markers (CD11b/CD68) and anti-inflammatory markers (CD206/CD163) following exercise training in …
