MOVEMENT PATTERNS – THE ESSENCE OF SPORTS BIOMECHANICS<br />

Figure 1.10 Another young female walking on a level treadmill at her preferred speed in high-heeled shoes. Top left: left foot<br />

<strong>to</strong>uchdown (0 s); <strong>to</strong>p right: right foot <strong>to</strong>e-off (0.14 s); middle left: left foot mid-stance; middle right: right foot<br />

<strong>to</strong>uchdown (0.52 s); bot<strong>to</strong>m left: left foot <strong>to</strong>e-off (0.64 s); bot<strong>to</strong>m right: right foot mid-stance.<br />

(we would then be functioning as gait analysts)? Differences from this normal pattern,<br />

for one, but also right–left side differences, variations across strides, how joint and<br />

contralateral limb movements are coordinated, and how external fac<strong>to</strong>rs, such as<br />

changed task or environmental constraints, affect the gait pattern. Video sequences,<br />

as in Figures 1.7 <strong>to</strong> 1.12, are not necessarily the best movement pattern representation<br />

for these purposes, as we shall see in Chapter 3.<br />
