A muscle fiber generates maximum contractile force when:

Question

Quizplus · Accepted Answer

Muscle fibers generate maximum contractile force when they receive repeated action potentials from a nerve, allowing for a sustained contraction. This is known as tetanus contraction. Excessive stretching can damage the muscle fibers, and exposure to creatine phosphate can improve the muscle's ability to generate ATP, but does not directly increase contractile force. Muscle fibers contracting and relaxing at the same time is not possible as it would result in no net movement.
