Abstract:

The energy cost of carrying loads of 15 and 45 pounds in five different distributions, has been studied on a horizontal, motor-driven treadmill maintained at 3.5 mph. The hypothesis that extra energy is required for accelerating and decelerating loads that are attached to body parts which undergo rapid changes in velocity during walking has received support from the findings of this study. The feasibility of loads balanced fore and aft on the upper thorax is suggested. Measurements of pulmonary function are in no way different from those obtained for the other experimental distributions. Two groups of test subjects, a fat and a lean group, have followed an identical schedule. It has been found that the fat group has a slight disadvantage in carrying a given external weight, as compared to lean carriers.QRDC abstract See also AD-0021-004
