External mechanical work and power were measured for eight athletic runners by means of force platform and 16mm cine camera.
The results were summarized as follows: 1) At lower running velocity up to 5-6m/sec the velocity was increased mainly by the increment of step length, but at the velocity higher than 6m/sec step frequency increased curvilinearly with running velocity. 2) The force exerted by the foot in horizontal direction (F_f) increased linearly with the velocity from about 90N at 3m/sec to 260N at maximum velocity. 3) The power output per body weight in forward direction (P_f) increased as 2nd power of the velocity up to 40-50watt/kg at the maximum velocity. 4) Significant linear relationship was found between the power (P_f) and the propelling force (F_f) (r=0.971, p<0.001). 5) The power output in per body weight in vertical direction (P_v) was increased up to about 16.5watt/kg in proportion to the velocity. 6) At the velocity higher than 6m/sec, the mechanical power by forward velocity change (Pf) increased gradually greater than that against gravity (P_v) but at the lower velocity than 5m/sec P_f was always less than P_v.

The differences between experimental group (the 9 wheel-chaired) and control group (the 11 normal able-bodied) on feelings which was occured by change of hight conditions of kitchen unit were measured by Semantic Differential Method and Nowlis's Check List of Mood. Compared with low level kitchen unit (experimental group: the hight of patella on each wheel-chair plus depth of sink, control group: stature/3+35cm), high level kitchen unit (plus 10cm to each hight) resulted in decline of image and mood of both group, but the tendency was appeared obviously for the experimental group. It was certifyed that the handicapped were effected directly from physical settings which didn't fit to their features by two kind of self-rating scales.
