The peak forces produced in response to each fatiguing train during the three fatigue protocols (c) for a representative subject. Raw force responses of the first (a) and last (b) fatiguing trains for each of the three fatigue protocols. Note that for the modulation protocols, the force in response to the last train is either equal to or greater than the force in response to the first train. In contrast, the no-modulation protocol causes a decline in force from the first to the last train.
