Older versus younger (light versus dark grey) biomechanical measures: (A) Negative Eccentric Work (J/kg). (B) Rectus femoris eccentric contraction EMG burst duration (s). (C) Rectus femoris %EMG segment weight dynamic movement (SWDM). (D) Rectus femoris eccentric contraction EMG peak latency (s) (E) Postural sway (SD of CoM acceleration) during SLS in the A-P, M-L, and vertical directions. (F) Margin of Stability (normalized to normal gait, %) of first compensatory step touchdown following perturbations. (G) Maximum vertical velocity of swinging leg for compensatory step. * represent a statistically significant difference between older and younger adults (p < 0.05). The error bars display the standard error. # represent a statistically significant difference between the directions (p < 0.05).
