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.

Noradrenergic regulation of skeletal muscle oxygen pressures: Impact of heart failure with preserved ejection fraction and heat therapy

Experimental Physiology, EarlyView.
Abstract Attenuation of sympathetic vasoconstriction during exercise (functional sympatholysis) contributes to skeletal muscle oxygen delivery–utilization matching. However, the extent to which muscle contractions impact noradrenergic regulation of interstitial oxygen pressures (PO2is${P_{{{\mathrm{O}}_2}}}_{{\mathrm{is}}}$; the driving force for blood–

Left ventricular morphological and functional predictors of V̇O2peak${\dot V_{{{\mathrm{O}}_2}{\mathrm{peak}}}}$: A 3‐year observational study

Experimental Physiology, EarlyView.
Abstract The aim of the study was to identify central determinants of V̇O2peak${\dot V_{{{\mathrm{O}}_2}{\mathrm{peak}}}}$ using a 3‐year longitudinal evaluation of left ventricular (LV) morphological and functional (global, tissue‐Doppler and strain) outcome measures obtained at rest and during both submaximal and maximal exercise in a group of highly
