Fig. 7. Mean tendon length change of 10 subjects, relative to the tendon length
calculated when standing still, of 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, standard deviations are
omitted.
