Muscle tone occurs when motor units are always active, producing a constant level of tension in the muscle even when it is at rest. Treppe refers to the phenomenon where a series of contractions increase in strength due to increased Ca2+ availability. Tetany refers to sustained contractions due to rapid firing of action potentials. Fatigue refers to a decline in muscle performance due to prolonged activity. A twitch is a brief, single contraction of a muscle fiber.
