Figure 1. Change in leg blood flow and vascular conductance with infusion of ACh.

ACh was infused at 10 (ACh 1), 25 (ACh 2), and 100 μg min^-1 (kg leg mass)^-1 (ACh 3) in normotensive (n = 10) and hypertensive (n= 9) subjects before and after 8 weeks of aerobic exercise training. Values are means ±SEM. †Overall effect of training on leg vascular conductance in the hypertensive group.
