Historically, many studies investigating the pulmonary physiology of exercise (and
biomedical research in general) were performed exclusively or predominantly with male …

The respiratory muscles encompass a variety of functions and roles, their action during
exercise facilitates arterial blood-gas and pH regulation. Exercise hyperpnea is the first line …

It is unknown whether central hemodynamics are impaired during exercise in chronic
obstructive pulmonary disease (COPD) patients. We hypothesized that, at a similar absolute …

New Findings What is the central question of this study? What is the effect of age and sex on
the resistive and viscoelastic components of work of breathing (Wb) during exercise? What …

The mechanical work of breathing (Wb) is an insightful tool used to assess respiratory
mechanics during exercise. There are several different methods used to calculate the Wb …

New Findings What is the central question of this study? The goal of this study was to
investigate the effect of alterations in tidal volume and alveolar volume on the elevated …

Given there are both sex-based structural differences in the respiratory system and age-
associated declines in pulmonary function, the purpose of this study was to assess the …

This study examined the impact of aging on the elastic and resistive components of the work
of breathing (W b) during locomotor exercise at a given 1) ventilatory rate, 2) metabolic rate …

Ageing is a progressive condition that usually leads to the loss of physiological properties.
This process is also present in respiratory muscles, which are affected by both senescent …

Exertional dyspnea (ED) and impaired exercise performance (EP) are mainly caused by
dynamic hyperinflation (DH) in chronic obstructive pulmonary disease (COPD) patients by …
