Percent changes in vessel inner diameter in control (Ctrl: n = 8), diabetic (Stz: n = 8), and treadmill running diabetic (Exe: n = 7) mice during infusion of 0.1 and 1.0 μg/kg/min acetylcholine, categorized by vessel class, 1) conduit (popliteal) artery, 2) over 100 μm arteries, and 3) under 100 μm arterioles. Data in parentheses represent the number of vessels which were averaged. Values are expressed as mean ± SE. *P < 0.05
