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