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

Experimental 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.

CO2 chemoreflex contributions to ventilatory long‐term facilitation

The Journal of Physiology, EarlyView.
Abstract figure legend To determine whether changes in CO2 chemoreflex sensitivity contribute to ventilatory long‐term facilitation (LTF), we tested the hypothesis that hypercapnic acute intermittent hypoxia (AIH) induces ventilatory LTF and enhances peripheral, but not central, chemoreceptor CO2 chemoreflex sensitivity.
