Effect of chronic high‐altitude hypoxia on retinal vascular phenotype, choroidal and retinal vasoreactivity in Peruvian highlanders

open access: yesExperimental Physiology, EarlyView.
Abstract High‐altitude chronic hypoxia can induce excessive erythrocytosis (EE, defined as a haemoglobin concentration of ≥21 g/dL in men), leading to hyperviscosity and promoting endothelial dysfunction. We aimed to assess whether EE affects the retinal vascular phenotype and the ophthalmological vascular response to CO2.

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

open access: yesThe 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.

Ventilatory and cerebrovascular responses to exercise in lowlander children acclimatizing to high‐altitude

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend To investigate age‐related differences in ventilatory and cerebrovascular responses to exercise at high‐altitude, adults (n = 10, 23–44 years) and children (n = 8, 7–14 years) completed progressive cycling exercise tests at sea‐level and following 6 days of acclimatization at 3800 m.

Effects of online motor cortex transcranial ultrasound stimulation on interhemispheric inhibition

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The present study investigated the online effect of primary motor cortex (M1) transcranial ultrasound stimulation (TUS) on interhemispheric inhibition (IHI) from the sonicated M1 to the contralateral M1 and on the contralateral M1 excitability.

Transcranial direct current stimulation enhances delayed retention after 5 days of lower‐limb motor skill learning

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the 5 day lower‐limb motor skill learning protocol combining ankle visuomotor practice with transcranial direct current stimulation (tDCS). Participants were allocated to motor skill practice with active tDCS over the leg representation of primary motor cortex (SKILL‐STIM), motor skill practice with sham ...
