The sex-specific effects of high vs. low muscle sympathetic nerve activity (MSNA) on peak changes in mean arterial pressure (MAP) and limb vascular conductance (LVC). There was a significant interaction effect (sex × MSNA level) on ΔMAP (A). Post hoc analyses indicated male participants with lower resting MSNA demonstrated greater changes in ΔMAP compared with male participants with higher resting MSNA (n values for MAP: low MSNA females = 12, high MSNA females = 13, low MSNA males = 12, high MSNA males = 12). There was a significant main effect of resting MSNA level on ΔLVC (B). Post hoc analyses indicated male participants with lower MSNA demonstrated greater changes in ΔLVC compared with male participants with higher resting MSNA, but this was not the case in female participants (n values for LVC: low MSNA females = 10, high MSNA females = 9, low MSNA males = 10, high MSNA males = 10). Data are means ± SD. We performed a median split to determine high vs. low MSNA. *P < 0.05, high vs. low MSNA.
