The data in this table are previously unpublished values collected at the State University of New York at Stony Brook and at Duke University.

Different samples were used for different studies.

The study of maximum walking speed and stride length involved 7 men and 7 women between the ages 19 and 55 (mean = 30) whose height ranged from 1.5 m to 1.94 m (average = 1.7 m).

The study of vertical peak force magnitude involved 7 women and 5 men between the ages of 18 and 55 (mean = 23) whose height ranged from 1.5 m to 1.84 m (average = 1.62 m).

The speed range of the subjects in this study was relatively narrow and subjects walked relatively fast (average speed for straight-legged walking =2.03 m s^{-1} and for bent-hip, bent-knee walking = 2.13 m s^{-1}).

Finally, the study of impact shock attenuation involved 6 men and 5 women between ages of 19 and 35 (average = 22) whose height ranged from 1.6 m to 1.84 m (average = 1.6 m). In this latter study, average speed for normal walking = 1.78 m s^{-1} and for compliant walking=1.92 m s^{-1}.
