Sex differences in diaphragmatic fatigue: the cardiovascular response to inspiratory resistance

JF Welch, B Archiza, JA Guenette… - The Journal of …, 2018 - Wiley Online Library
Key points Diaphragmatic fatigue (DF) elicits a sympathetically mediated metaboreflex
resulting in increased heart rate, blood pressure and limb vascular resistance. Women may …

Effect of diaphragm fatigue on subsequent exercise tolerance in healthy men and women

JF Welch, B Archiza, JA Guenette… - Journal of applied …, 2018 - journals.physiology.org
Women are more resistant to diaphragmatic fatigue (DF) and experience an attenuated

Electrophysiological assessment of respiratory function

YCJ Kuo, KHS Chen - Handbook of Clinical Neurology, 2022 - Elsevier
While the traditional lung function tests are used to assess lung capacity and pulmonary

Diaphragm fatigue and inspiratory muscle metaboreflex in men and women matched for absolute diaphragmatic work during pressure‐threshold loading

CM Geary, JF Welch, MR McDonald… - The Journal of …, 2019 - Wiley Online Library
Key points The female diaphragm fatigues at a slower rate compared to that of males, with

Acute intermittent hypercapnic‐hypoxia elicits central neural respiratory motor plasticity in humans

JF Welch, J Nair, PJ Argento… - The Journal of …, 2022 - Wiley Online Library
Acute intermittent hypoxia (AIH) elicits long‐term facilitation (LTF) of respiration. Although
LTF is observed when CO2 is elevated during AIH in awake humans, the influence of CO2 …

Effects of hypoxia on exercise‐induced diaphragm fatigue in healthy males and females

PA Reinhard, B Archiza, JF Welch… - Physiological …, 2023 - Wiley Online Library
Following high‐intensity, normoxic exercise there is evidence to show that healthy females,
on average, exhibit less fatigue of the diaphragm relative to males. In the present study, we …
