Fig. 2. Two consecutive representative strides at 0.5 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).
