Heart rate during isometric handgrip (IHG) and post-exercise ischaemia (PEI) under control (black symbols), β-adrenergic blockade (light grey symbols) and parasympathetic blockade (dark grey symbols) conditions A shows absolute heart rate during all experimental phases, while B shows the change (Δ) in heart rate from rest during IHG and PEI. PEI-M, PEI following 25% IHG; PEI-H, PEI following 40% IHG. *P < 0.05 vs. exercise, †P < 0.05 vs. control, ‡P < 0.05 vs.β blockade, #P < 0.05 vs. 25% MVC.
