Imposed expiratory resistance, dynamic hyperinflation and locomotor power and fatigue

open access: yesExperimental Physiology, EarlyView.
Abstract Expiratory flow limitation results in dynamic hyperinflation, dyspnoea and premature exercise intolerance. We aimed to measure whether expiratory resistance reduces locomotor power via limiting maximal voluntary motor activity, exacerbating muscle fatigue, or both.

Persistence of fatigue in the absence of pathophysiological mechanisms in some patients more than 2 years after the original SARS‐CoV‐2 infection

open access: yesExperimental Physiology, EarlyView.
Abstract Following an acute infection with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), a substantial percentage of patients report the persistence of debilitating symptoms, often grouped in a syndrome termed ‘long COVID’. We sought to identify potential pathophysiological mechanisms responsible for the persistence, in some long COVID ...

Optimizing the predictive validity of NIRS kinetic profiles to predict aerobic capacity from a resting skeletal muscle occlusion test

open access: yesExperimental Physiology, EarlyView.
Abstract Measuring and monitoring individual cardiorespiratory fitness through a valid and accessible non‐exhaustive surrogate is required. Techniques measuring haemodynamics have shown promise, and this study aimed to optimize the predictive validity of these approaches alongside developing predictive equations.

Validation of muscle oxygenation kinetics to predict aerobic fitness and exercise transition thresholds

open access: yesExperimental Physiology, EarlyView.
Abstract The aim of this study was to validate previously developed equations to predict maximal oxygen uptake (V̇O2max${\dot V_{{{\mathrm{O}}_{\mathrm{2}}}{\mathrm{max}}}}$) from near‐infrared spectroscopy (NIRS) during and after a period of limb ischaemia.

Steepest near‐infrared spectroscopy‐derived deoxygenation slopes during arterial occlusions provide more reliable assessments of muscle mitochondrial capacity

open access: yesExperimental Physiology, EarlyView.
Abstract Assessment of near‐infrared spectroscopy (NIRS)‐derived muscle oxidative capacity relies on analysing deoxygenation slopes from NIRS signal versus time curves during brief arterial occlusions, which reflect the rate of post‐exercise recovery of muscle oxygen consumption (V̇O2m${\dot V_{{{\mathrm{O}}_2}{\mathrm{m}}}}$).
