Figure 2. Heart rate (HR) and mean arterial pressure (MAP) during leg cycling and post-exercise ischaemia (PEI) for the control, β-adrenergic blockade and parasympathetic blockade conditions.

A and C, 1 min averages of absolute HR and MAP, respectively, during all experimental phases of the control (black symbols), β-adrenergic blockade (light grey symbols) and parasympathetic blockade (dark grey symbols) conditions. B and D, change in HR and MAP, respectively, elicited at the last minute of leg cycling (Ex, black bars) and PEI (dark grey bars) in each condition. Rec, recovery. *P < 0.05 vs. Ex, †P < 0.05 vs. control; ‡P < 0.05 vs. β-blockade.
