Mean summary data for muscle sympathetic nerve activity burst frequency (MSNA BF, A), mean arterial pressure (MAP, B), and heart rate (HR, C) during lower-body positive pressure (LBPP) at baseline (hatched bars) and during postexercise ischemia (PEI) following low (white bars)-, medium (gray bars)-, and high (black bars)-intensity isometric handgrip, and PEI combined with LBPP (PEI + LBPP). *P < 0.05, baseline vs. LBPP in LBPP alone trial. †P < 0.05, low-intensity PEI vs. medium-intensity PEI. ‡P < 0.05, medium-intensity PEI vs. high-intensity PEI. ¶P < 0.05 PEI vs. PEI + LBPP.
