Effects of bed rest and immobilization on intramuscular and intermuscular adipose tissue: A systematic review

open access: yesExperimental Physiology, EarlyView.
Abstract Muscle disuse caused by bed rest and immobilization is associated with muscle atrophy and insulin resistance, which might be related to increases in intramuscular fat (IntraMAT) and intermuscular fat (InterMAT) accumulation. In this systematic review, we compiled evidence on the effects of bed rest and unilateral lower‐limb immobilization on ...

Stretch versus shortening contractions subsequently decrease versus increase neural drive to the human tibialis anterior

open access: yesExperimental Physiology, EarlyView.
Abstract EMG‐based muscle force predictions are often inaccurate following active muscle stretch or shortening because of residual force enhancement (rFE) or depression (rFD), respectively, which can alter the neural drive to a muscle. However, the extent of neural drive modulation attributable to rFE or rFD remains unknown owing to the limited spatial

Effects of nocturnal periodic breathing on sympathetic nerve activity and ventilatory control at high altitude: a randomised, crossover study

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the randomised crossover study investigating the effects of nocturnal periodic breathing (nPB) on sympathetic activity and ventilatory acclimatisation in hypobaric hypoxia equivalent to 4000 m altitude. Participants completed two 3‐day sojourns where nPB was inhibited by increasing inspiratory CO2 fraction ...

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Low‐threshold cutaneous mechanoreceptors on the foot sole have enhanced sensitivity when skin temperature is elevated

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic illustration of microneurography recordings used to examine the effects of local skin heating on cutaneous mechanoreceptor responses in the human foot (left panel). A microelectrode inserted into a peripheral nerve records single‐unit activity from tactile afferent fibres while controlled mechanical stimuli are applied ...
