Passive hyperthermia increases blood circulation in specific regions, largely independent of conduit artery mechanics and cardiac performance

Experimental Physiology, EarlyView.
Abstract Passive hyperthermia increases net peripheral and systemic blood flow in humans and other animals, yet the underlying haemodynamic forces that selectively accelerate blood movement remain incompletely characterized. Wave intensity analysis offers insight into the respective contributions of the heart and the vascular system to changes in blood

Postexercise muscle oxygen uptake kinetics in older breast cancer survivors and healthy individuals: Association with myosteatosis

Experimental Physiology, EarlyView.
Abstract Reduced cardiorespiratory fitness is common among breast cancer survivors and, although traditionally attributed to cardiac dysfunction, might also be related to peripheral skeletal muscle abnormalities. We examined peak and submaximal plantar‐flexion exercise and recovery kinetics for lower‐leg oxygen uptake (V̇O2${\dot V_{{{\mathrm{O}}_2}}}$)

Interindividual variability in static apnoea performance is partly explained by genetic factors

Experimental Physiology, EarlyView.
Abstract A large interindividual variability exists in maximal apnoea duration and the physiological adjustments that occur during apnoea. Although a few genes have been found to be associated with some of the cardiovascular responses during apnoea, the extent to which genetic and environmental factors contribute to individual differences in apnoea ...

Identification of the individual cardiac contraction threshold during high‐frame‐rate stress echocardiography

Experimental Physiology, EarlyView.
Abstract The clinical assessment of cardiovascular function during exercise using stress echocardiography is essential for accurate cardiac diagnosis. However, normal limitations of cardiac deformation responses to increasing physical exertion remain poorly understood.

The isolated working guinea pig heart: A functional and electrophysiological characterisation

Experimental Physiology, EarlyView.
Abstract Small animal isolated perfused hearts have been used for over 150 years for the study of cardiac physiology and pharmacology. The guinea pig heart represents the smallest mammalian heart that replicates key features of the human heart – for example, with respect to cardiac action potential duration, ion channel expression, excitation ...
