The strongest muscle contractions are normally achieved by .

Question

Quizplus · Accepted Answer

Increasing the stimulation up to the maximal stimulus can activate all of the muscle fibers within a motor unit, leading to the strongest muscle contractions. This is known as maximal recruitment. Option B is incorrect because once a muscle fiber reaches its maximal level of contraction, further increases in stimulus intensity will not result in stronger contractions. Option C is also incorrect because treppe, also known as the "staircase effect," refers to the phenomenon where successive stimuli of the same intensity lead to increasing levels of muscle contraction, but this effect plateaus at a certain threshold. Option D is incorrect because recruiting small and medium muscle fibers alone may not result in the strongest muscle contractions, as larger muscle fibers can generate more force.
