Contribution of sympathetic nervous system activation to endothelial ischemia reperfusion injury in healthy adults. [PDF]

Physiol Rep
Abstract Ischemia–reperfusion injury (IRI) describes the phenomenon through which the restoration of blood flow following prolonged ischemia exacerbates tissue damage during reperfusion. IRI can be modeled by inducing 20‐min arm ischemia followed by reperfusion.

Dietary flavanols preserve upper- and lower-limb endothelial function during sitting in high- and low-fit young healthy males. [PDF]

J Physiol
Abstract figure legend Schematic indicating the design of an acute randomised, counterbalanced, double‐blinded, cross‐over, placebo‐controlled human study in which 20 high‐fit males and 20 low‐fit males consumed either a low‐flavanol (5.6 mg) or a high‐flavanol (695 mg) cocoa drink prior to a 2 h uninterrupted sitting bout.

Arterial function in response to a 50 km ultramarathon in recreational athletes. [PDF]

Exp Physiol
Abstract This study was performed to determine whether prolonged endurance running results in acute endothelial dysfunction and wave‐reflection, as endothelial dysfunction and arterial stiffness are cardiovascular risk factors. Vascular function (conduit artery/macrovascular and resistance artery/microvascular) was assessed in 11 experienced runners (8

The impact of a superfood chocolate beverage on indices of peripheral vascular function. [PDF]

Physiol Rep
Abstract Elevated blood lipids and reduced vascular health contribute to cardiovascular disease. Diets and/or interventions high in antioxidants, polyphenols, and anti‐inflammatory properties mitigate this risk. This study hypothesized that daily consumption of a beverage high in antioxidants, polyphenols, and anti‐inflammatory properties would improve

Impaired inactive limb blood flow regulation in adults with multiple sclerosis during sympathoexcitatory stimuli. [PDF]

Physiol Rep
Abstract Individuals with multiple sclerosis (MS) exhibit reduced physical capacity, partly due to autonomic dysfunction. Autonomic impairments are well documented, but peripheral blood flow regulation during exercise remains unclear. We compared peripheral vascular responses to dynamic handgrip exercise, with and without a mild sympathoexcitatory ...

Effects of acute ketone monoester ingestion on heart rate, blood pressure and muscle sympathetic nerve activity at rest and stress in healthy adults. [PDF]

Physiol Rep
Abstract Exogenous ketone supplementation can impact cardiovascular regulation, but the effects on muscle sympathetic nerve activity (MSNA) remain unknown. In a randomized, crossover, double‐blind design, 19 participants (23 ± 4 years.; female: n = 9) ingested an oral ketone monoester (KME; 0.4 g/kg) or isocaloric, isovolumetric placebo. Blood pressure,

Baseline arterial stiffness does not influence post-exercise reduction in pulse wave velocity. [PDF]

Physiol Rep
Abstract We manipulated baseline peripheral arterial stiffness via changes in local arterial pressure with different limb positions to test the hypothesis that the magnitude of decrease in arterial stiffness post exercise/compression would be less when baseline stiffness is higher with the arm below the heart.

Reliability of popliteal artery flow-mediated dilation in the seated position. [PDF]

Physiol Rep
Abstract Flow‐mediated dilation (FMD), a noninvasive measure of endothelial function, is commonly measured in the popliteal artery in the supine and upright body positions. However, reliability studies of the measurement in these positions are not well studied.

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

Experimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.

Report results: Impact of whole‐body resistance exercise timing on mitigating hyperglycaemia‐induced vascular dysfunction in healthy adults

Experimental Physiology, EarlyView.
Abstract Postprandial hyperglycaemia is characterized by elevated blood glucose levels following a meal and is associated with impaired vascular endothelial function. Regular exercise has been shown to preserve and improve vascular endothelial function.
