A century of exercise physiology: key concepts on coupling respiratory oxygen flow to muscle energy demand during exercise
After a short historical account, and a discussion of Hill and Meyerhof's theory of the
energetics of muscular exercise, we analyse steady-state rest and exercise as the condition …

Simultaneous assessment of central and peripheral chemoreflex regulation of muscle sympathetic nerve activity and ventilation in healthy young men
Key points Central chemoreceptor stimulation, by hypercapnia (acidosis), and peripheral, by
hypoxia plus hypercapnia, evoke reflex increases in ventilation and sympathetic outflow …

Methodological validation of the dynamic heterogeneity of muscle deoxygenation within the quadriceps during cycle exercise
The conventional continuous wave near-infrared spectroscopy (CW-NIRS) has enabled
identification of regional differences in muscle deoxygenation following onset of exercise …

Unexplained exertional intolerance associated with impaired systemic oxygen extraction
KH Melamed, M Santos, RKF Oliveira… - European journal of …, 2019 - Springer
Purpose The clinical investigation of exertional intolerance generally focuses on
cardiopulmonary diseases, while peripheral factors are often overlooked. We hypothesize …

Dynamics of the RR-interval versus blood pressure relationship at exercise onset in humans
Purpose The dynamics of the postulated phenomenon of exercise baroreflex resetting is
poorly understood, but can be investigated using closed-loop procedures. To shed light on …

Baroreflex dynamics during the rest to exercise transient in acute normobaric hypoxia in humans
Purpose We hypothesised that during a rest-to-exercise transient in hypoxia (H), compared
to normoxia (N),(i) the initial baroreflex sensitivity (BRS) decrease would be slower and (ii) …

Dynamics of cardiovascular and baroreflex readjustments during a light-to-moderate exercise transient in humans
Purpose We hypothesised that, during a light-to-moderate exercise transient, compared to
an equivalent rest-to-exercise transient,(1) a further baroreflex sensitivity (BRS) decrease …
