C) produce smooth, continuous muscle contraction
D) increase muscle tension

Question

Quizplus · Accepted Answer

Wave summation refers to the addition of successive motor unit twitches in order to produce a smooth, continuous contraction. This is achieved by increasing the frequency of stimulation, which leads to a greater release of calcium from the sarcoplasmic reticulum and thus more cross-bridge cycling between actin and myosin filaments. The result is increased tension development and a sustained contraction.
