The cardiac pacemakers: A paradigm of robustness in evolutionary biology

The Journal of Physiology, EarlyView.
Abstract figure legend Functional networks in living systems are formed by many thousands of gene products. In association with those networks, several genes (four in this diagram) may be sufficient, each on its own, to ensure that the function occurs. Any one of these may be removed or blocked while leaving the others to continue functioning.

Neuromuscular fatigability with repeated exercise in hypoxia: From single‐joint paradigms to sprints

The Journal of Physiology, EarlyView.
Abstract figure legend Acute hypobaric or normobaric hypoxic exposure accelerates neuromuscular fatigability during repeated exercise. Indices of peripheral and central fatigue are not different at exhaustion in mild, moderate and severe hypoxia compared with normoxia, but task failure occurs earlier.

Exacerbated ATP transmission in the carotid body is linked to glomus cell expansion in spontaneously hypertensive rats

The Journal of Physiology, EarlyView.
Abstract figure legend Exacerbated ATP signalling in the carotid body (CB) of spontaneously hypertensive rats (SHRs) arises from expansion of the chemosensory glomus cell compartment and reduced extracellular ATP metabolism, leading to increased purinergic drive.

Determinants of maximal oxygen uptake in highly trained females and males: a mechanistic study of sex differences using advanced invasive methods

The Journal of Physiology, EarlyView.
Abstract figure legend The results from this study show that maximal cardiac output, stroke volume and leg blood flow are similar between highly trained females and males after normalisation to lean body mass (LBM). However, the 10% higher haemoglobin concentration ([Hb]) and arterial O2 content in males result in higher systemic and leg O2 delivery ...

Elevated carotid body tonic activity contributes to ventilatory acclimatization and de‐acclimatization to high altitude at rest and during exercise

The Journal of Physiology, EarlyView.
Abstract figure legend Participants spent 13 days at high altitude (3800 m), where the reduced inspired oxygen pressure (↓PiO2$ \downarrow {P_{{\mathrm{i}}{{\mathrm{O}}_2}}}$) which elicited ventilatory acclimatization and increased inhibition of ventilation by transient hyperoxia (ΔV̇E$\Delta {\dot V_{\mathrm{E}}}$).
