Figure 2


Fig. 2. Mean locomotory power (ground reaction force x centre of mass velocity) of 10 subjects over one full descending stride cycle for all four step-heights: decreased 50% (dotted lines), standard (thin lines), increased 50% (thick lines) and increased 75% (thick broken lines). Vertical lines indicate foot-contact times [lift-off (LO) right, touch-down (TD) right and LO left] for both conditions, whereas 0 and 100% of the stride cycle indicate TD of the left (analyzed) foot. For clarity, only positive standard deviations of the standard step-height are presented.
