Fig. 3. Whole-body angular momentum and moment. (A) A normalized angular momentum for walking is plotted about three orthogonal directions versus percentage gait cycle. The angular momentum is normalized by the product of each participant's mass, CM height and self-selected gait speed (MVH; see Table 1 for values). (B) Normalized CM moment is plotted about three orthogonal directions versus percentage gait cycle. Moment is normalized by the product of each participant's weight and CM height (MGH). For both A and B, the solid line is the mean normalized value, and the dashed lines are one standard deviation about the mean (10 participants and seven walking trials per participant). In addition, 0% and 100% gait cycles correspond to consecutive heel strikes of the same foot.
