Question

Quizplus · Accepted Answer

Before the entire muscle can change length, the force generated by the muscle must be transmitted to the tendons and other connective tissues that make up the series elastic elements. These elements have the ability to store elastic energy, which can then be released to help generate force during subsequent contractions. The parallel elastic elements help to maintain muscle stiffness and resistance to passive stretch, while the contractile elements are responsible for generating the force that causes muscle movement. However, neither of these elements are directly involved in the process of lengthening the muscle.
