Representative centre of mass trajectories and adaptation metrics.
(A) Representative set of centre of mass trajectories of two consecutive successful trials. (B, C) Total changes of Trajectory Area and Initial Trajectory Area, with changes between two consecutive successful trials (S-S) shown in pink and those between two consecutive successful trials separated by at least one failed trial (S-F-S) shown in blue. Error bars show standard error of the mean. (D) Representative set of centre of mass trajectories before and after a failed trial with successful trials shown in green and failed trials shown in red.
