Fig. 6. Summary histograms of peak muscle stress, active fascicle strain, net work
per stride and tendon elastic energy recovery per stride (means ±
S.E.M.) for the lateral gastrocnemius (LG, left) and digital
flexor-4 (DF-IV, right) across speed for level (open bars) and incline (filled
bars) locomotion. Shortening muscle strains are negative. See
Table 3 for relevant sample
sizes.
