Elastic energy storage and the efficiency of movement
Elastic energy and biological springs When a material is subjected to a force, F, it deforms. During this deformation, the force moves over a fi nite displacement, x, and thus does work, Fx. This work can be stored as elastic potential energy (E elastic). A perfectly elastic material returns all the work done on it and thus acts like an ideal

The ability to control a movement in real time after unlatching would likely not be possible in organisms where the muscle only contributes energy during energy storage, and where the latch temporally decouples energy storage from energy return (Roberts, 2019). Thus, latches like the anuran latch may result in reduced efficiency and robustness

Elastic Energy
Elastic energy. Elastic energy is energy stored in an object when there is a temporary strain on it – like in a coiled spring or a stretched elastic band.. The energy is stored in the bonds between atoms.The bonds absorb energy as they are put under stress and release the energy as they relax (when the object returns to its original shape).
Elastic energy
Elastic energy is the mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally deformed in any manner. Elasticity theory primarily develops formalisms for the mechanics of solid bodies and
