Abstract:
The energy cost of wearing an eight-pound, laminated nylon, armored vest with zipper closed was measured while the subjects were walking, with and without a 40-pound pack load, on a treadmill, on a level course, and climbing slopes of from three to 22 degrees. The armored vest imposed a measurable increase in metabolic rate when worn over the fatigue uniform. These increases became greater as the steepness of the slope increased. Wearing of the vest under the pack had a negligible or, perhaps, even favorable effect on carrying loads on the three- and six-degree grades in some individuals, but on the steep slopes it caused an increase in the metabolic rate about equal to that imposed by the vest alone. The extra load and binding effect of the armored vest became of greatest importance at high activity levels, such as rapid climbing over a steep grade.QRDC abstract See also AD-12-244
