From page 347...
... The metabolic measurements reported herein indicate that the energy cost of locomotion in simulated lunar gravity is considerably less than in 1 g, as was found in earlier studies. The simulation technique used was unimportant for level walking, but generally had a large effect on the metabolic data obtained while ascending grades.
From page 348...
... In the rotatingvehicle simulator, a cable suspension system similar to that of the inclined-plane simulator was used. Figure 4 presents the ratio of the floor reaction force to the subject's Earth weight plotted against foot contact time.
From page 349...
... ENERGY EXPENDITURE As has been pointed out, the imminence of the lunar missions has resulted in an emphasis on the evaluation of walking in lunar g, especially the examination of the metabolic costs that will be incurred. The following data are concerned, therefore, with the energy costs of self-locomotion in simulated lunar gravity.
From page 350...
... The gimbal-vertical simulator results generally indicate substantially higher energy expenditures than those obtained with the inclined plane. Steady-state metabolic data were not obtained for the 30° slope in the vertical simulator, except at very low walking rates of 1 km/hr, because the subject's heart rate exceeded 180 beats/min before steady-state conditions could be obtained.
From page 351...
... Six times his body weight on the lunar surface would be equivalent to his body weight on the Earth. Letko: I believe some experiments were made in a l/6-g simulator in which enough weight was added to the subject to bring him back to Earth weight and indicated that he could gravity Traction Simulation on the Energy Cost of Walking.
