Motor unit summation is the build-up of the myoelectrical signals of the active motor unit during continuous, sustained muscle contraction. Sustained contraction causes the motor unit to fire continuously, creating myoelectrical signal fusion that produces larger forces than a single contraction.

With multiple muscle stimulations, the calcium in the sarcoplasm actually increases. Higher calcium levels in muscle tissue correspond with more powerful contractions. Calcium increases the power of muscle contractions by making the cross-bridges in the muscle more active. Muscle contraction is also influenced by motor unit summation.
