Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

Experimental Physiology, Volume 111, Issue 11, Page 5094-5104, 1 November 2026.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

Transcranial doppler for carotid endarterectomy

European Journal of Vascular and Endovascular Surgery, 1996
Patients with symptomatic high-grade carotid artery stenosis benefit from carotid endarterectomy. However, the operation is not without complications. The perioperative stroke rate varies from 2 to as much as 24% and depends on technique and patient selection. Seventy percent of perioperative strokes occur during the operation and are equally caused by

Cerebrovascular flow‐mediated dilation in humans: Methodological challenges, physiological interpretation and future integrations

Experimental Physiology, Volume 111, Issue 11, Page 5061-5073, 1 November 2026.
Abstract Arterial shear‐mediated vasodilation is a well‐established measure of endothelial function and serves as a critical biomarker for cardiovascular disease risk. Endothelial function can be measured using a variety of experimental methodologies; however, the most widely adopted technique is ultrasound‐based flow‐mediated dilation (FMD), in which ...

A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

Experimental Physiology, Volume 111, Issue 11, Page 5154-5165, 1 November 2026.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

Sex differences in dynamic cerebral autoregulation responses to resistance and endurance training in humans

Experimental Physiology, Volume 111, Issue 11, Page 5250-5264, 1 November 2026.
Abstract Exercise maintains brain health and reduces the risk of cerebrovascular diseases, such as stroke and dementia. The benefits of different ‘modalities’ of exercise on male and female cerebral autoregulation are unclear. In this study, we compared adaptations in dynamic cerebral autoregulation (dCA) during spontaneous and forced oscillations in ...

CARE‐ing for concussions: Development of the Calgary Adapted aRm Ergometer (CARE) exertion test: A physiological alternative to the Calgary Concussion Cycle Test

Experimental Physiology, Volume 111, Issue 11, Page 5166-5184, 1 November 2026.
Abstract Aerobic exercise testing helps facilitate recovery post‐concussion. Current protocols (Calgary Concussion Cycling Test: CCCT) are inaccessible for athletes with lower‐body impairments (i.e. Para athletes). This study compared physiological parameters for a novel arm crank test, the Calgary Adapted aRm Ergometer (CARE) test, with the CCCT ...

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

Experimental Physiology, Volume 111, Issue 11, Page 5185-5204, 1 November 2026.
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.

Cerebrovascular regulation during heat stress

Experimental Physiology, Volume 111, Issue 11, Page 5052-5060, 1 November 2026.
Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.
