Fig. 2.

Representative examples of the anterior (top) downward (bottom) velocities of the center of mass (COM) during functional reaching (solid line) and up-and-reach (dashed line) for a young (left) and an older (right) adult. A reaching event is defined from the initial position (0 %) to the farthest position (100 %) of the finger marker. For the young adult, the difference between functional reach (solid line) and up-and-reach (dashed line) was minimal, while for the older adult, the difference was more apparent
