Mean number of capillaries per individual type I, IIA, and IIX fibers in the vastus lateralis muscle before and after the T period in CTL and MHD patients with NT, ET, ST, and EST. Values are means ± SE. Note: with EST the number of capillaries per individual fiber type increased in type I (7%, *P < 0.001), IIA (4%, *P < 0.05), and IIX (3%, *P < 0.05) fibers, whereas ET increased it in type I (6%, *P < 0.01) and type IIA (4%, *P < 0.05) fibers.
