NEW FINDINGS: What is the central question of the study? The prevalence of hypertension in Black individuals exceeds other racial groups. Despite this well-known heightened risk, the underlying contributing factors remain incompletely understood. Herein, we hypothesized young black men would exhibit augmented beat-to-beat blood pressure variability compared to white men. Furthermore, we hypothesized black men would exhibit augmented total peripheral resistance variability. What is the main findi...

Approximately 60% of patients with type 2 diabetes mellitus (T2D) develop hypertension. Recent work also indicates greater blood pressure (BP) excursions throughout the day in T2D. Collectively, th...

We demonstrate that cutaneous microvascular responses to local heating are consistently reduced in otherwise healthy young black men and women relative to their white counterparts. Inhibition of NA...

: The mechanism(s) for the increased occurrence of a grayout or blackout, syncope, immediately after heavy resistance exercise are unclear. It is well-known that orthostatic stress increases the occurrence of postexercise syncope. In addition, previous findings have suggested that hypo-perfusion, especially in the posterior cerebral circulation rather than anterior cerebral circulation, may be associated with the occurrence of syncope. Herein, we hypothesized that the postexercise decrease in po...

NEW FINDINGS: What is the central question of this study? We aimed to examine leg vascular responses to brief periods of inactivity. What is the main finding and its importance? We demonstrate that a mere 10 min of sitting is sufficient to impair leg microvascular function (reactive hyperaemia). However, conduit artery vasodilatation (flow-mediated dilatation) was unaffected, indicating maintained macrovascular function. Interestingly, immobile supine rest also resulted in a reduction in microva...

NEW FINDINGS: What is the central question of this study? To understand better the effects of acute hyperglycaemia on arterial stiffness in healthy young individuals, we assessed arterial stiffness in physically active men before and after reduced ambulatory physical activity to decrease insulin sensitivity. What is the main finding and its importance? During an oral glucose tolerance test, we identified an increase in leg arterial stiffness (i.e. reduced femoral artery compliance) only when sub...
