The role of pannexin/purinergic signaling in intervascular communication from capillaries during skeletal muscle contraction in male Golden hamsters [PDF]

Physiological Reports
We sought to determine the physiological relevance of pannexin/purinergic‐dependent signaling in mediating conducted vasodilation elicited by capillary stimulation through skeletal muscle contraction.

Characterization of Cecal Smooth Muscle Contraction in Laying Hens

Veterinary Sciences, 2021
The ceca play an important role in the physiology of the gastrointestinal tract in chickens. Nevertheless, there is a gap of knowledge regarding the functionality of the ceca in poultry, especially with respect to physiological cecal smooth muscle ...

The Transient Mechanics of Muscle Require Only a Single Force-Producing Cross-Bridge State and a 100 Å Working Stroke

Biology, 2020
An informative probe of myosin cross-bridge behaviour in active muscle is a mechanical transient experiment where, for example, a fully active muscle initially held at constant length is suddenly shortened to a new fixed length, providing a force ...

Auditory sEMG biofeedback for reducing muscle co‐contraction during pedaling

Physiological Reports, 2022
Muscle co‐contraction between the agonist and antagonist muscles often causes low energy efficiency or movement disturbances. Surface electromyography biofeedback (sEMG‐BF) has been used to train muscle activation or relaxation but it is unknown whether ...

Sensory gating and suppression of subjective peripheral sensations during voluntary muscle contraction

BMC Neuroscience, 2020
Background During voluntary muscle contraction, sensory information induced by electrostimulation of the nerves supplying the contracting muscle is inhibited and the somatosensory evoked potentials (SEPs) amplitude decreases.

Microstructural analysis of skeletal muscle force generation during aging. [PDF]

, 2020
Human aging results in a progressive decline in the active force generation capability of skeletal muscle. While many factors related to the changes of morphological and structural properties in muscle fibers and the extracellular matrix (ECM) have been ...

Endurance training facilitates myoglobin desaturation during muscle contraction in rat skeletal muscle. [PDF]

, 2015
At onset of muscle contraction, myoglobin (Mb) immediately releases its bound O2 to the mitochondria. Accordingly, intracellular O2 tension (PmbO2) markedly declines in order to increase muscle O2 uptake (mVO2).

An electrooptical muscle contraction sensor [PDF]

, 2010
An electrooptical sensor for the detection of muscle contraction is described. Infrared light is injected into the muscle, the backscattering is observed, and the contraction is detected by measuring the change, that occurs during muscle contraction ...
