Explanation:
Detailed explanation-1: -Following contraction or extension, a muscle can return to its original length when relaxed due to a quality of muscle tissue called elasticity. It can recoil back to its original length due to elastic proteins.
Detailed explanation-2: -Elasticity: With elasticity, a muscle is able to return to its original resting shape and length after being extended or contracted.
Detailed explanation-3: -By influencing the speed of contractile elements, elastic structures can have a profound effect on muscle force, power and work. In very rapid movements, elastic mechanisms can amplify muscle power by storing the work of muscle contraction slowly and releasing it rapidly.
