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.
