Muscle contraction - Wikipedia, the free encyclopedia

Muscle fiber generates tension through the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten or remain the same. Though the term 'contraction' impl...

The purpose of this study was to evaluate the integrity of the muscle membrane and its associated cytoskeleton after a contraction-induced injury. ... These data indicate the selective vulnerability of dystrophin after a single eccentric contraction-induced injury and suggest a critical role of dystrophin in force transduction.

1. Histological evidence suggests that the force deficit associated with eccentric contraction-induced muscle injury is due to structural damage to contractile elements within the muscle fibre. Alternatively, the force deficit could be explained by an inability to activate the contractile proteins.

An eccentric contraction occurs when a muscle is contracting, and an external force is trying to lengthen the muscle. The classic mechanism for a muscle strain is an eccentric contraction. ... Eccentric contractions are the common cause of injuries such as a groin pull or hamstring strain...

Concentric & Eccentric Contraction ... Eccentric contraction involves the development of tension whilst the muscle is being lengthened e.g. the downward movement of a dumbbell in a biceps curl or when you land on two feet from a jump and bend your knees the quadriceps are lengthening.

The effect of eccentric contraction on force generation and intracellular pH (pHi) regulation was investigated in rat soleus muscle. Eccentric muscle damage was induced by stretching muscle bundles by 30% of the optimal length for a series of 10 tetani.

Strength deficits associated with eccentric contraction-induced muscle injury stem, in part, from excitation-contraction uncoupling. ... There were no differences between FKBP12-deficient and WT mice in preinjury peak isometric and eccentric torques when normalized to body weight, and no differences in the relative...
