- The sliding filament model of contraction is a theory that is used to explain how muscles contract to cause movement. The theory explains that the change in the length of the muscle during contraction is due to the sliding of the myofilaments past each other and not to a change in the length of either of the myofilaments.arrow_forwardDescribe the following regions/structures of a sarcomere.
