Examining the roles of core and local temperature on forearm skin blood flow
… Data are presented as a percentage of maximal cutaneous vascular conductance (CVC), calculated as laser-Doppler flux divided by mean arterial pressure. Tloc manipulations performed during normothermia had significantly greater effects on CVC than during hyperthermia. The decreased modification …

Dietary nitrate supplementation augments nitric oxide synthase-dependent and independent reflex cutaneous vasodilation in healthy humans
… BRJ supplementation would augment reflex cutaneous active vasodilation. Subjects were equipped with two microdialysis fibers on the forearm and randomly assigned as control (Ringer’s) or NOS inhibition (20mM L-NAME). Whole-body heating was achieved via water-perfused suits to raise core …

Quantifying the Relationship of Bilateral Blood Flow in Glabrous Skin at Rest and During Sympathetic Perturbations
… measure directly, the possibility of using blood conductance as an indirect measure seems promising. We investigated the relationship of bilateral blood conductance recordings of both middle fingers in ten (7M, 3F) healthy participants, while at rest and in response to perturbations known to …

Regional differences in the control of the cutaneous circulation in humans
… probes in nine healthy volunteers. Baseline cutaneous vascular conductance (CVC) (laser-Doppler flow / blood pressure) was measured at a local skin temperature (Tloc) of 33 °C and 42 °C. All data are expressed as CVC. In study 1, forearm and calf sites were compared to determine if SkBF …

The effect of skin temperature on cardiovascular responses during endurance exercise
… skin temperature (T [subscript sk]) on cardiovascular responses and the independent effect of heart rate on stroke volume when Tsk is hot and cold during moderate intensity endurance exercise. In study 1, we systemically evaluated the effect of graded increases in T [subscript sk] from 32°C to …

Influence of upper limb ischaemia-reperfusion injury on the regulation of cutaneous blood flow during local thermal hyperaemia
… upper limb ischaemia- reperfusion (I-R) on neurovascular and endothelial control of the cutaneous micro-circulation in the forearm and finger by evaluating its influence on the magnitude and kinetics of the vasodilatory response to local skin heating. Study 1 investigated between-day reliability …

Effects of external and internal precooling on sudo- and vasomotor responses and adaptations to heat acclimation
Background Heat acclimation and precooling are strategies commonly used to mitigate heat stress during exercise in the heat. Physiological adaptations during heat acclimation include lower core temperature (Tcore), lower heart rate (HR), and increased sweat output during exercise at a given …

The impact of exercise and thermal training interventions on thermoregulatory and cardiovascular function in young and post-menopausal females
… reproductive hormone oestrogen influences cardiovascular and thermoregulatory control. A dramatic decline in oestrogen during the menopause causes cardiovascular and thermoregulatory dysfunction resulting in hot flushes (HFs). HFs consist of feelings of intense heat with rapid increases in …

Effects of Tea on Peripheral and Cerebral Micro- and Macrovascular Function in Humans
Cardiovascular disease (CVD) is the leading cause of global mortality, with the incidence of cardiovascular related pathologies remaining a public health burden. CVD encompasses pathologies of the vascular tree and heart, including, for example, peripheral artery disease, coronary heart disease and …
