Figure 3

Mean vastus lateralis firing rate (pulses per second, pps) of the constant force phase of the isometric TRAP effort for: (A) early‐; (B) mid‐; and (C) later‐recruited motor units during EO and constant load (CL) conditions with target 2sec (f) and 4sec (s) knee extension eccentric phases. *= 0.04 decrease between before‐ and after‐intervention measures. Insert graph is showing individual responses for later recruited motor units before and after EO. EO, eccentric overload.
