Figure 1. Leg vascular resistance and noradrenaline spillover across the leg of untrained healthy controls and patients with chronic heart failure with reduced ejection fraction (HFrEF) before (pre) and after (post) knee‐extensor exercise (KE) training during KE at 50% of maximal KE capacity.

Data are presented as mean ± SE. ^* P < 0.05 post vs. pre; ^#P < 0.05 HFrEF vs. controls.
