Fig. 2. Body rotation and deflection of the COM during the stance period of four
conditions, straight running steps with the right (SR; magenta line) and left
(SL; black line) legs, sidesteps with the right leg (TR; blue line) and
crossovers with the left leg (TL; green line). Both angles are expressed in
initial movement direction reference frame. Angles were scaled to percentage
of the stance period, and averaged. Vertical whiskers denote s.e.m. at each
phase of stance.
