Fig. 5. Percentage of 95th percentile males with su$cient hip strength
for four task elements as determined in the independent evaluation
conducted in 1990 and the 3DSSPP/AutoCADanalysis. The di!erence
between the two studies for the low rack (manual) task element is due to
di!erences in posture selection: the analysts in the 1990 study used
a symmetric foot placement whereas the 3DSSPP/AutoCAD analyst
used an asymmetric foot placement.
