Residual force enhancement after stretch in striated muscle. A consequence of increased myofilament overlap?
When skeletal muscle is stretched above optimal sarcomere length during tetanic activity there is an increase in force that stays above the isometric force level throughout the activity period. This long-lasting increase in contractile force, generally referred to as "residual force enhancement after stretch" (Fresid), has been studied in great detail in various muscle preparations over more than
