Physiological mechanisms underlying enhanced performance with blood flow restriction training: neuromuscular, vascular and metabolic adaptations

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We investigated how 6 weeks of dynamic knee‐extensor interval training with blood flow restriction (BFR‐leg) and without (CTRL‐leg) impacts performance and its mechanisms using non‐invasive methods. Specifically, we used gold‐standard methods to assess neuromuscular function, vascular function using Doppler ultrasound, and near ...

Mitochondrial physiology in cardiac muscle of deer mice native to high altitude

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude deer mice exhibited evolved changes in mitochondrial energy metabolism and reactive oxygen species (ROS) management that may support cardiac performance under cold hypoxic conditions. High‐altitude mice had increased activity of lactate dehydrogenase (LDH) in the heart, probably enhancing the capacity for lactate ...

SARS‐CoV‐2 targets mitochondria, exacerbating COVID‐19 pneumonia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Following entry into airway epithelial cells (AECs), SARS‐CoV‐2 releases its single‐stranded RNA into the cytoplasm, where it is translated into viral proteins. Several of these viral proteins localize to mitochondria and interact with key mitochondrial components.

Post‐exercise ketone supplementation improves endurance performance and mitochondrial adaptations during an 8‐week endurance training intervention

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐eight trained males completed 8 weeks of supervised indoor cycling training, receiving post‐exercise and pre‐sleep ketone monoester (KE, n = 14) or isocaloric placebo (CON, n = 14). Both groups improved 30 min time‐trial performance with training, but KE achieved a 4% higher power output than CON at the end of the training

Vascular smooth muscle cell mechanotransduction: Pathways, phenotypes and emerging technologies

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Vascular smooth muscle cells are exposed to mechanical stimuli from the blood flow and the extracellular matrix. The cells sense the signals from cyclic stretch, shear stress, hydrostatic pressure and matrix stiffness through specialized mechanosensors, such as mechanosensitive ion channels or cell surface receptors including ...

Diving into the unknown: Evidence of enhanced skeletal muscle lactate efflux potential and blood–muscle exchange in competitive breath‐hold divers

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Competitive breath‐hold divers exhibit skeletal muscle characteristics indicative of enhanced blood‐muscle exchange capacity and increased lactate efflux potential. Top left: Participant characteristics, matched for age, height, body mass, and maximal oxygen uptake (V̇O2max${\dot{\mathrm{V}}}\rm{O}_{\rm{2max}}$).

Restoration of neuromuscular function by mitochondrial transplantation in injured mouse skeletal muscle

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Mice received chemical injury (cardiotoxin) in the tibialis anterior muscle of one limb, and the contralateral muscle was injected with phosphate‐buffered saline (PBS) as a sham control. Mice then received PBS or mitochondria suspended in PBS into the tail vein.

Sprint‐interval training with post‐exercise blood flow restriction increases mitochondrial content and respiration

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The mechanisms underpinning improved maximal oxygen uptake following sprint interval training (SIT) with post‐exercise blood flow restriction (BFR), compared to SIT alone, remain unclear. This study examined the effects of 6 week SIT with (BFR; n = 12) or without (CON; n = 8) post‐exercise BFR on V̇O2peak${{\dot{V}}_{{{{\mathrm{O}
