Combined stimuli of elasticity and microgrooves form aligned myotubes that characterize slow twitch muscles

Scientific Reports
Skeletal muscles are classified into slow-twitch muscles composed primarily of type I and IIa fibers with high oxidative metabolism, and fast-twitch muscles composed of type IIx and IIb fibers with high glycolytic metabolism.

Hypoxia and hypercapnia elicit overlapping but distinct skeletal muscle toxicities

The Journal of Physiology, EarlyView.
Abstract figure legend Hypoxia and hypercapnia cause overlapping skeletal muscle phenotypes, including atrophy, change in myofibre metabolic profile and myogenic response to injury. Both signals operate via distinct cellular pathways. Abstract Skeletal muscle dysfunction is strongly associated with elevated mortality in acute and chronic pulmonary ...

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

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

The 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 ...

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 ...

Comparison of myosin isoenzymes from slow-tonic and fast-twitch fibers of frog muscle.

European journal of cell biology, 1981
Myosin from distal cruralis bundle of triceps femoris composed of slow-tonic and fast-twitch fibers in an about 1 to 1 ratio, from rectus abdominis containing a lower proportion of slow-tonic fibers, and from a fast-twitch sartorius muscle of the frog, was characterized by means of polyacrylamide gel electrophoresis in the presence of sodium ...

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.
