Fig. 3. Two consecutive representative strides at 2.0 m s^–1 on a level (solid lines) and inclined (broken lines) treadmill showing the changes in fascicle length (A) for the LG (red), pMG (blue) and dMG (blue). A scale bar for fascicle strain is to the right of each panel. The corresponding EMG signals (for level only) are also shown in black with a scale bar to the right. The shaded regions indicate the stance phases of the strides. (B) Muscle stress corresponding with the strides in A for the LG (red) and MG (blue).
