This graph shows that the optimum length (LO) of the CP is approximately 1.7 times its resting length (LR), whereas in other striated muscles LO = LR. This relationship illustrates the large degree of elasticity of the CP compared to other striated muscles. (Source: Medda et al.,26 with permission of the American Physiological Society.)
