The aims of this study were to relate heart morphology and functions changes to heart rate
variability (HRV) components after acclimatization to high altitude and to define whether …

The within-breath modulation of muscle sympathetic nerve activity (MSNA) is well
established, with greater activity occurring during expiration and less during inspiration …

The primary aim of this study was to determine the influence of systemic hyperoxia on
sympathetic nervous system behavior at rest and during submaximal exercise in humans. In …

Key points In an anaesthetised animal model, independent stimulation of baroreceptors in
the pulmonary artery elicits reflex sympathoexcitation. In humans, pulmonary arterial …

Responses in muscle sympathetic activity (MSA) to acute hypoxia were studied in 13 healthy
male subjects under hypobaric hypoxic conditions at a simulated altitude of 4,000, 5,000 …

Journal of Physiology, Waltz et al.(2016) tackle a very important question: can we reduce the
impairment in cerebral autoregulation that is found in subjects with obstructive sleep apnoea …

Obstructive sleep apnea is associated with sustained elevation of muscle sympathetic nerve
activity (MSNA) and altered chemoreflex control of MSNA, both of which likely play an …

The spleen contains a reservoir of red blood cells that are mobilized into circulation when
under physiological stress. Despite the spleen having an established role in compensation …

Acute intermittent hypoxia (AIH) is a frequently studied experimental model of obstructive
sleep apnoea (OSA). AIH can elicit a long-term increase in sympathetic outflow (long-term …
