Values are means ± SE; n = 16 except for systolic blood pressure (SBP) and diastolic blood pressure (DBP) (n = 12 mild and n = 13 moderate exercise). HR, heart rate; MAP, mean arterial pressure; MSNA/100, muscle sympathetic nerve activity (burst incidence); HFrEF, heart failure with reduced ejection fraction.
