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.
