No difference in mean middle cerebral artery blood velocity responses between lower‐ and upper‐body unilateral resistance exercise in untrained individuals

Experimental Physiology, EarlyView.
Abstract Dynamic resistance exercise (RE) produces sinusoidal fluctuations in blood pressure that are mirrored by middle cerebral artery blood velocity (MCAv). However, whether lower‐ or upper‐body RE elicits a differential cerebrovascular response has not yet been examined.

The theoretical basis of reservoir pressure in arteries

Experimental Physiology, EarlyView.
Abstract The separation of measured arterial pressure into a reservoir pressure and an excess pressure was introduced over 20 years ago as a heuristic hypothesis. Since then it has gained some traction through epidemiological studies that show that various measures of reservoir and excess pressure are independent risk factors for cardiovascular disease.

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

Experimental Physiology, EarlyView.
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 the prefrontal cortex and muscle oxygenation during exercise until exhaustion in endurance‐trained individuals

Experimental Physiology, EarlyView.
Abstract figure legend During cardiopulmonary exercise testing, the decline in oxygenation in the prefrontal cortex of women is striking. This crucial brain area is directly involved in planning motor tasks. The decline is particularly pronounced at higher exercise intensities, especially after reaching the respiratory compensation point or anaerobic ...

Cerebrovascular regulation during heat stress

Experimental Physiology, EarlyView.
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.

Vascular and skeletal muscle oxidative capacity responses to continuous double and single leg cycling

Experimental Physiology, EarlyView.
Abstract The purpose of this work was to determine endothelial, microvascular, skeletal muscle oxidative capacity (SMOC) and cardiorespiratory responses to an acute bout of continuous single leg cycling (SLC) and double leg cycling (DLC). Ten recreationally active men and women volunteered to participate in this investigation and reported to the ...
