Experiments on the post-contraction hyperaemia of skeletal muscle

Biomimetic model of skeletal muscle isometric contraction: II. A phenomenological model of the skeletal muscle excitation-contraction coupling process

This paper describes a new macroscopic, phenomenological model of the skeletal muscle excitation-contraction coupling process, as represented by four principal and consecutive compartments (biophysical, biochemical, and biomechanical phases) characteristic of isometric excitation-contraction coupling in mammalian skeletal muscle, and coupled by a system of simultaneous, first-order linear ordin...

Excitation-contraction coupling in skeletal muscle.

Chemo-mechanical model for skeletal muscle contraction

Generation of force in skeletal muscle tissue depends on both chemical and mechanical phenomena. In this work, considering the kinetics of cross bridges, a one dimensional model has been proposed for predicting the isometric force according to the intracellular calcium ion distribution. Introduction The different ways of skeletal muscle activation lead to the formation of cross bridges (XB) acc...

Metabolic Inhibition During Rat Skeletal Muscle Contraction

Our previous studies in rat skeletal muscle have determined that neural constriction of large arterioles, which regulate blood flow and peripheral resistance, is mediated by al-adrenoceptors, whereas small arterioles, which determine effective capillary density, depend on £V2receptors. During physical exercise, metabolic vasodilators from contracting skeletal muscle oppose neural vasoconstricti...

The effects of muscle contraction and insulin on glucose-transporter translocation in rat skeletal muscle.

The effect of electrically induced muscle contraction, insulin (10 m-units/ml) and electrically-induced muscle contraction in the presence of insulin on insulin-regulatable glucose-transporter (GLUT-4) protein distribution was studied in female Sprague-Dawley rats during hindlimb perfusion. Plasma-membrane cytochalasin B binding increased approximately 2-fold, whereas GLUT-4 protein concentrati...
