Question

Quizplus · Accepted Answer

The total number of muscle fibers (cells) available for contraction is the main factor that determines the power of a muscle. The more muscle fibers a muscle has, the more force it can generate. Other factors such as the length, shape, and innervation of the muscle can influence its performance, but the number of muscle fibers is the most important determinant of muscle power.
