Jacobson discovered that after holding a muscle contraction and then releasing the contraction, the muscle fibers elongate. What is unique about elongated muscle fibers?
What will be an ideal response?
These elongated muscle fibers are more relaxed and can be trained to reach a zero firing threshold (i.e., the neurons that tense these muscle fibers do not exceed their firing thresholds), a phenomenon that is verifiable with an electromyograph instrument. When a person reaches this level after contracting, holding, and releasing forearm tension for instance, the hand goes limp like a wet dishrag.
