Blood flow restriction: The acute effects of body tilting and reduced gravity analogues on limb occlusion pressure

Experimental Physiology, EarlyView.
Abstract Blood flow restriction (BFR) has been identified as a potential countermeasure to mitigate physiological deconditioning during spaceflight. Guidelines recommend that tourniquet pressure be prescribed relative to limb occlusion pressure (LOP); however, it is unclear whether body tilting or reduced gravity analogues influence LOP.

Systolic‐dominant coronary flow in rats and mice: Challenging the diastolic paradigm across conscious and anaesthetized states

Experimental Physiology, EarlyView.
Abstract Extensive research in humans, dogs, rabbits, rats, mice and other mammals has consistently demonstrated that coronary blood flow (CBF) peaks during ventricular diastole. For example, studies using transthoracic Doppler echocardiography in anaesthetized rats and mice, isolated blood‐perfused rat hearts and Doppler probes sutured to the ...

Establishment of a mouse model for ischaemic heart failure induced by coronary microembolization via left ventricular oil injection

Experimental Physiology, EarlyView.
Abstract Over the past three decades, there has been a steady increase in clinical attention to ischaemic heart failure caused by coronary microembolization. Nonetheless, a suitable mouse model for studying this condition remains limited. In the present study, we developed a mouse model of coronary microembolization‐induced ischaemic heart failure by ...

Blood flow restriction exercise during microgravity exposure in parabolic flight

Experimental Physiology, EarlyView.
Abstract This case report evaluates whether it is possible to perform blood flow restriction (BFR) exercise during exposure to microgravity. The objectives were three‐fold: (1) to determine if a personalised tourniquet system (PTS) hardware technology performs nominally and enables BFR exercise in microgravity; (2) to determine if BFR augments the ...

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
