Human Performance in the Tropics II: A Pilot Study on Load-Carrying Test Methodology
Abstract
A Pilot Study on Load Carrying Test Methodology was conducted in 1973 by the US Army Tropic Test Center in the Panama Canal Zone to determine sample sizes needed in future tests requiring a jungle patrol, and to determine the utility of two human performance decrement measurements. Combat troops carried loads from 25 to 55 pounds over a 4-kilometer jungle portability course simulating combat activity. In general, time to perform activities tended to increase with increased load. Sample sizes of 12 groups of three individuals, or 16 groups of two individuals, were determined as sufficient for future normative data collection studies within the 25- to 55-pound load range. A land navigation test demonstrated potential usefulness as a performance decrement measure, if revised to eliminate measurement problems encountered in the pilot test. An arm-hand steadiness test provided procedural guidelines for establishing psychomotor tests as a part of the portability course.
