Eight male subjects, aged 20.3-33.5, walked on the motor-driven treadmill at 100m/min. The grade of the treadmill was increased 5% every four minutes from 0%. All subjects performed on the treadmill till exhaustion. The results obtained were as follows : 1) Maximal oxygen uptake was obtained from treadmill walking test with increasing grade. Mean VO_2 max for eight subjects was 3.59 l/min (S. D. : 0.36 l/min). 2) A significant positive correlation (r=0.934, p<0.001) was found between oxygen uptake and heart rate. The regression equation of oxygen uptake on heart rate was Y=36.6X+67 1. 3) The linear correlation coefficient between work load and oxygen uptake was 0.979 (P<0.001). The regression relationship was given by Y=0.0018X+0.818. 4) The work load during treadmill walking at 0% was 326.7 kgm/min, calculated from the regression equation of work load on oxygen uptake. (Y=0.0018X±0.818).
