Cerebral haemodynamic responses to inspiratory muscle work

Experimental Physiology, EarlyView.
Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.

Lower limb blood flow responses during higher‐ and lower‐load bilateral leg press exercise

Experimental Physiology, EarlyView.
Abstract The local blood flow response to resistance exercise (RE) is complicated by local muscular contractions and large swings in perfusion pressure. The magnitude of these responses might vary according to exercise intensity, number of sets and number of repetitions, and as a result, the local shear environment during RE remains uncharacterized. We

Physiological evaluation of the Calgary adapted aRm ergometer (CARE) concussion exertion test in adolescent athletes: A repeated‐measures observational study

Experimental Physiology, EarlyView.
Abstract Exertion testing helps inform exercise prescription during concussion recovery. The Calgary Adapted aRm Ergometer (CARE) test, developed as the first upper‐body specific exertion test, aims to improve accessibility and inclusivity in concussion care.

Cerebral blood flow regulation, central arterial stiffness and traumatic brain injury: Effects of aerobic exercise training

Experimental Physiology, EarlyView.
Abstract Advanced age is the strongest risk factor for Alzheimer's disease and related dementias (ADRDs). Traumatic brain injury (TBI) has also been recognized as a risk factor for ADRD, potentially contributing to an earlier onset of the disease. Thus, elucidating the mechanisms underlying brain ageing and TBI is critical for developing strategies to ...

Passive hyperthermia increases blood circulation in specific regions, largely independent of conduit artery mechanics and cardiac performance

Experimental Physiology, EarlyView.
Abstract Passive hyperthermia increases net peripheral and systemic blood flow in humans and other animals, yet the underlying haemodynamic forces that selectively accelerate blood movement remain incompletely characterized. Wave intensity analysis offers insight into the respective contributions of the heart and the vascular system to changes in blood

Plant‐protein supplementation improves thermoregulatory responses and ameliorates markers of intestinal damage during exercise in the heat

Experimental Physiology, EarlyView.
Abstract Exercise in the heat often causes gastrointestinal (GI) disturbances, which can impair performance. Single amino acid supplementation can attenuate gut damage and enhance exercise tolerance; however, the effectiveness of innate amino acid blends from plant‐based proteins remains underexplored.

Is resting muscle sympathetic nerve activity related to peripheral or cerebrovascular haemodynamics at high altitude? A retrospective analysis

Experimental Physiology, EarlyView.
Abstract High‐altitude hypoxia elicits several profound physiological responses, including substantial increases in muscle sympathetic nerve activity (MSNA); however, the association of this heightened MSNA with cardiovascular and cerebrovascular haemodynamics remains unclear in lowlanders and indigenous highlander populations.
