Energy storage is low because the size of the elastic deformation is low. The size of the working stroke of a cross-bridge, estimated from x-ray diffraction and contractile measurements on single fibers ( Reconditi et al ., 2004 ; Piazzesi et al ., 2007 ), can be as high as 10–13 nm.
When a material is first exposed to force, it behaves elastically. Elastic behavior means that however the material moves while under load, it returns to its original position when the load is removed. This is true for every material, although sometimes the elastic regime might be really small.
We say that the stretched rubber band or compressed spring stores elastic energy—the energy account used to describe how an object stores energy when it undergoes a reversible deformation. This energy can be transferred to another object to produce a change—for example, when the spring is released, it can launch a dart.
