The acute effects of exercise intensity and inorganic nitrate supplementation on the Buckberg ratio in postmenopausal females

open access: yesExperimental Physiology, EarlyView.
Abstract Menopause increases coronary heart disease risk, in part through reduced oestrogen‐mediated nitric oxide (NO) bioavailability. The Buckberg ratio, an index of myocardial oxygen supply–demand balance, in which higher values reflect more favourable myocardial perfusion, is lower in postmenopausal females (PMFs) than in age‐matched males.

Sex differences in macrovascular responsiveness: Acute effects of hot water immersion versus aerobic exercise in overweight older adults

open access: yesExperimental Physiology, EarlyView.
Abstract Recent studies have focused on the potential benefits of heat exposure for cardiovascular health. However, the acute effects of heat therapy on conduit arteries remain unclear, particularly in overweight and obese older males and females. This study aimed to compare core temperature (Tc), heart rate (HR), and brachial, femoral, and carotid ...

Exercise intolerance and impaired aerobic capacity in heart transplant recipients

open access: yesExperimental Physiology, EarlyView.
Abstract Heart transplant recipients exhibit reduced exercise tolerance and persistently diminished aerobic capacity despite exercise training. Exercise tolerance depends on integrated oxygen transport and utilization, which are impaired in heart transplant recipients.

Resistance‐trained young men exhibit enhanced carotid vasoreactivity during the cold pressor test

open access: yesExperimental Physiology, EarlyView.
Abstract The function of the common carotid artery (CCA) is integral to the regulation of cerebral perfusion. Although endurance training is associated with consistent vascular benefits, the effects of resistance training on CCA function are unclear.
