Talk about muscle resting..

AKA filament sliding method, it is marked by the shortening of muscle cell resulting from the sliding of the fine filaments on the thick filaments. When a muscle is at rest, Muscular cells are relaxed: thin and thick filaments overlap only for a small part of their length, Ca++ ions are in the terminal cisternae, ATP linked to myosin union bridges and actin linked tropomyosin and troponin complex interposes between myosin heads and actin binding sites, preventing their binding.
