Abstract

Abstract : This study examined the cognitive and physiological performance of soldiers as they carried loads over various terrains. Twelve soldiers each carried a light load (total weight, including clothing, 22.77 kg 50.19 LB) and a heavy load (total weight, including clothing, 36.94 kg 81.43 LB) over three terrains: blacktop road, sand, and mud. The cognitive tasks performed by the soldiers included arithmetical, memory, and monitoring tasks. The physiological variables were oxygen uptake, ventilation rate, heart rate, and rating of perceived exertion. Test participants also rated their overall workload after each trial. The results showed a significant (p = .018) Load x Block interaction for the monitoring task. In Block 2, the error rate for the light load condition was significantly lower than the error rate for the heavy load condition. There were significant main effects of load, terrain, and time for all the physiological variables. in this study, the energy expenditure (oxygen uptake) for walking on mud or loose sand was the same, and it was approximately 40% higher than the energy expenditure for walking on the blacktop road. Subjective ratings of workload showed significant differences as a function of load (p = .006) but not terrain.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
