Resting length of muscle definition
WebThe ideal length of a sarcomere to produce maximal tension occurs at 80 percent to 120 percent of its resting length, with 100 percent being the state where the medial edges of the thin filaments are just at the most-medial myosin heads of the thick filaments (Figure 10.14). This length maximizes the overlap of actin-binding sites and myosin heads. WebThe ideal length of a sarcomere to produce maximal tension occurs at 80 percent to 120 percent of its resting length, with 100 percent being the state where the medial edges of the thin filaments are just at the most-medial myosin heads of the thick filaments (). This length maximizes the overlap of actin-binding sites and myosin heads.

WebSmooth muscles can contract over a wider range of resting lengths because the actin and myosin filaments in smooth muscle are not as rigidly organized as those in skeletal and cardiac muscle. Single-unit smooth … WebActually, this means that a muscle which has contracted under concentric or isometric conditions is simply returning under eccentric conditions to its original resting length. To avoid confusion like this, it is preferable to define muscle action as follows (where proximal refers to the "nearest" end of the muscle and "distal" to the "furthest" end):

WebOnce the muscle fiber is at its maximum resting length (all the sarcomeres are fully stretched), additional stretching places force on the surrounding connective tissue (see section Connective Tissue). As the tension increases, the collagen fibers in the connective tissue align themselves along the same line of force as the tension.
