gradually warms up.

is caused to produce isolated twitches.

Answer 1

To produce a contraction similar to the one in graph (b), the muscle must be stimulated to the point of fatigue.

Step-by-step explanation:

A muscle must be stimulated to the point of fatigue to produce a contraction similar to the one in graph (b). This means that the muscle must be repeatedly stimulated until it can no longer contract efficiently. This can be achieved by increasing the intensity of the stimulus or by stimulating the muscle multiple times before it has a chance to fully relax from the previous stimulation.
