Skeletal muscle adaptation to muscle activity and hypoxia: Differential structural and metabolic remodelling

The Journal of Physiology, EarlyView.
Abstract figure legend There has been controversy about the structural (capillary) response of skeletal muscle to altered O2 status, involving decreased supply (hypoxia) or increased demand (activity). Here we demonstrate that seven days of activation of skeletal muscle by indirect electrical stimulation led to significant expansion of the capillary ...

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

The 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 ...

Vibration acceleration enhances proliferation, migration, and maturation of C2C12 cells and promotes regeneration of muscle injury in male rats

Physiological Reports
Vibration acceleration (VA) using a whole‐body vibration device is beneficial for skeletal muscles. However, its effect at the cellular level remains unclear. We aimed to investigate the effects of VA on muscles in vitro and in vivo using the C2C12 mouse

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

The 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.

Stretching of Mechanoreceptors in Superior Tarsal Muscle Reflexively Contracts Slow-Twitch Fibers in Facial Expression Muscles: A Case Series

Cureus
Levator palpebrae superioris muscle (LPSM) and facial muscles comprise fast-twitch fibers (FTFs) and slow-twitch fibers (STFs) but lack muscle spindles required to contract STFs reflexively. Voluntary contractions and microsaccades of FTFs in LPSM stretch mechanoreceptors in superior tarsal muscle (STM) to induce phasic contractions of STFs in LPSM and

Caloric restriction and aerobic exercise differentially counteract muscle–tendon dysfunction following diet‐induced obesity in C57BL/6J mice

The Journal of Physiology, EarlyView.
Abstract figure legend Diet‐induced obesity induced fibro‐adipogenic remodelling of the muscle–tendon unit, characterized by increased fibrosis, reduced specific force, impaired relaxation kinetics, elevated hysteresis, and reduced aerobic capacity and glucose tolerance.

Voltage‐gated potassium channels mediate thyroid hormone control of skeletal muscle excitability

The Journal of Physiology, EarlyView.
Abstract figure legend Thyroid hormone (TH)‐dependent remodelling of potassium (K+) channel networks regulates skeletal muscle (SkM) excitability. Triiodothyronine (T3), locally generated from thyroxine (T4) by type 2 deiodinase (D2), binds thyroid hormone receptors (TRα/β) and modulates transcription via thyroid response elements (TREs).

Neuromuscular Fatigue and Perceived Fatigability in the Hours Following a High‐Intensity Endurance Running Depend on the Exercise Protocol

European Journal of Sport Science, Volume 26, Issue 8, August 2026.
ABSTRACT This study investigated neuromuscular fatigue and perceived fatigability across different high‐intensity endurance running protocols. Twelve males (mean ± SD; V˙O2max $\dot{\mathrm{V}}{\mathrm{O}}_{2\,\max }$: 52.2 ± 6.9 mL/kg/min) ran ∼8.0 km: (i) at the velocity associated to the respiratory compensation point (vRCP; 5 × 8 min bouts ‒ RUN100%

The Impact of Ageing on Skeletal Muscle: Roles of Mitochondrial Dysregulation, Systemic Communication, and Exercise

Journal of Cellular Physiology, Volume 241, Issue 8, August 2026.
ABSTRACT Ageing is a major risk factor for degenerative diseases, including sarcopenia, which is characterized by a progressive loss of skeletal muscle mass and function, frailty, and is associated with increased mortality. Skeletal muscle regeneration relies on muscle stem cells and efficient communication with cellular microenvironment.
