A typical fatigue envelope recorded from a rat includes a force potentiation phase, followed by a plateau at maximum force, a fatiguing phase, and a slow-fatiguing or fatigue-resistant phase. Parameters of a fatigue envelope include maximum force (Fmax), minimum force (Fmin), half fatigue time (T50), slope at T50 (slopeT50), and a fatigable muscle force index (F AUCT50).
