A student investigates the elastic properties of a latex band used in a model fitness strap. They measure the force applied and the resulting extension as the band is stretched (loaded) and then allowed to contract (unloaded). Their results are plotted on the graph below.

A force-extension graph for a latex band. The x-axis is labelled 'Extension' and the y-axis is labelled 'Force'. Two curves form a loop: the upper curve is labelled 'Loading' (as the force increases) and the lower curve is labelled 'Unloading' (as the force decreases). The region between the two curves is shaded gray.

Suggest what the shaded area between the loading and unloading curves represents.
