Fig. 6. Mean fascicle strain (A) and fascicle shortening velocity (B) for the LG, pMG and dMG walking (black; 0.5 m s^–1) and running (grey; 2.0 m s^–1) on a level (left pair of bars) and inclined (right pair of bars) treadmill. Note that strain increased for the LG and pMG with an increase in running speed on the level treadmill, but only for the LG on an inclined treadmill. Values are means ± s.e.m. (N=4).
