Quizplus · Accepted Answer

The proportion of muscle fibers within each motor unit that are contracting at any given time, also known as motor unit recruitment, is a determinant of whole-muscle tension. The other options - A) number of muscle fibers contracting, B) tension produced by each contracting fiber, C) numbers of motor units recruited, and D) frequency of motor neuron stimulation, all affect whole-muscle tension.
