Figure 4.
Tendon elasticity alters timing, but not the amount of energy absorbed by the muscle fascicles. Muscle mass-specific work during landing was calculated from muscle fascicle velocity and tendon force for the muscle fascicles, and from linear joint velocity and tendon force for the MTU. Energy absorption from the environment via joint flexion mainly happens during force rise (Frise, filled bars), but the muscle fascicles are effective energy sinks during force decay (Fdecay, unfilled bars). Bars are stacked averages, whiskers indicate 1 s.d.
