Posture-induced modulation of lower-limb joint powers in perturbed running
Fig 5
The relative contribution of the hip, knee and ankle joints to total limb power.
Pie charts depict the percentage of total average negative (A, level-step; B, drop-step) and positive (C, level-step; D, drop-step) power contributed at the hip (darker grey), knee (black) and ankle (lighter grey) joints during running with backward (TI¯), self-selected (TI0), low forward (TI+) and high forward (TI++) trunk inclinations. Green and black boxes indicate significant differences from TI¯ and TI0, respectively, while white boxes indicate a significant difference from the level-step. The size of each pie represents total average negative or positive power. In the absence of interaction effects, the horizontal and vertical lines denote significant differences between posture (in case of a Posture main effect) and step (in case of a Step main effect) conditions, respectively.
