Resistance exercise training (RET) alters the distance between satellite cells and their nearest capillary. A: satellite cell distance to nearest capillary in type I and type II fibers; data are expressed as mean µm ± SE. At baseline, the difference between the distance of satellite cells and their capillaries in each fiber type trended toward statistical significance (P = 0.06). B: representative immunohistochemical image demonstrating Laminin and type I fibers (pink), capillaries (yellow), myonuclei (blue), and satellite cells (green). A blue arrow denotes a Pax7+ satellite cell and a yellow arrow points to its closet capillary. #Significant interaction type × training (P < 0.05). Scale bar = 50 µm.
