Peak V̇O2Q${\dot V_{{{\mathrm{O}}_2}{\mathrm{Q}}}}$: A new approach for the interpretation of cardiorespiratory fitness estimates

open access: yesExperimental Physiology, EarlyView.
Abstract There are difficulties with the standardisation of interpretative strategies for peak oxygen uptake (peak V̇O2${\dot V_{{{\mathrm{O}}_2}}}$) related to the quality of reference equations. We aimed to investigate the utility of peak V̇O2Q${\dot V_{{{\mathrm{O}}_2}{\mathrm{Q}}}}$, a novel method reflecting how far a measured value is from the ...

A new method for bedside determination of effective lung volume and functional residual capacity

open access: yesExperimental Physiology, EarlyView.
Abstract Established methods of measuring functional residual capacity (FRC) involve sophisticated equipment and elaborate procedures. Here we present a new method based on CO2 rebreathing that has a simple fast procedure and only requires end‐tidal CO2 monitoring. Ten healthy subjects with diverse anthropometric and respiratory parameters were studied

Acute intermittent hypercapnic hypoxia augments left ventricular contractility

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...

Effects of nocturnal periodic breathing on sympathetic nerve activity and ventilatory control at high altitude: a randomised, crossover study

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the randomised crossover study investigating the effects of nocturnal periodic breathing (nPB) on sympathetic activity and ventilatory acclimatisation in hypobaric hypoxia equivalent to 4000 m altitude. Participants completed two 3‐day sojourns where nPB was inhibited by increasing inspiratory CO2 fraction ...
