Pressure‐dependent coupling between arterial pressure and intercostal muscle blood‐flow index during acute hypotension in humans

Experimental Physiology, EarlyView.
Abstract Regulation of respiratory muscle blood flow during acute systemic hypotension remains poorly understood in humans because continuous assessment of microvascular perfusion during rapid haemodynamic transients has been technically challenging. Using diffuse correlation spectroscopy, we investigated second‐by‐second coupling between mean arterial

Acute intermittent hypercapnic hypoxia augments left ventricular contractility

The Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...

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.

Reduced cardiovascular mortality at moderate altitude: a putative role of physical activity and body mass

The Journal of Physiology, EarlyView.
Abstract figure legend Benefits of performing physical exercise at moderate altitude. At moderate altitude, increased resting metabolic rate and physical exertion promote physical fitness and exercise tolerance, whereas hypoxia suppresses appetite and elicits adaptations that increase tissue O2 delivery while augmenting O2‐independent ATP production ...

Breathing irregularities and postnatal hypoxaemia in an experimental model of essential hypertension

The Journal of Physiology, EarlyView.
Abstract figure legend Neonatal spontaneously hypertensive rats (SHRs) exhibit inherent respiratory dysfunction in early life, including oscillatory breathing patterns and apnoeic events that cause oxygen desaturation and brain hypoxia, in addition to an impaired hypoxic ventilatory response.

Emerging Upper Extremity Muscle Ultrasound Patterns as a Diagnostic Aid in TTN‐Related Myopathies

Muscle &Nerve, Volume 74, Issue 1, Page 111-120, July 2026.
ABSTRACT Introduction/Aims Biallelic pathogenic variants in TTN cause rare forms of early‐onset myopathy, manifesting with variable severity, distribution, and progression of muscle weakness, often associated with respiratory insufficiency and potentially cardiomyopathy. The large size of TTN and phenotypic heterogeneity in TTN‐related myopathy (TTN‐RM)

Factors Impacting Tracheostomy Decisions in Korean Individuals With Amyotrophic Lateral Sclerosis: A Cross‐Sectional Survey

Muscle &Nerve, Volume 74, Issue 1, Page 159-172, July 2026.
ABSTRACT Introduction/Aims Decisions regarding tracheostomy are often made under emergent circumstances, although they require complex considerations of patient preferences, quality of life, and prognosis. This study investigated decision‐making surrounding tracheostomy in Korean people with amyotrophic lateral sclerosis (pwALS) and factors influencing
