Abstract:

The objective of this study was to establish a test methodology utilizing an operational scenario for assessing the effects of clothing and individual equipment CIE on Soldier physical and cognitive performance. This objective was accomplished by translating established scientifically based cognitive and physical metrics into an integrated field test batteryscenario. The 4-hour scenario was undertaken on each of 3 days wearing CIE configurations entailing load carriage ranging from approximately 10 to over 50 kg. The complete methodology was previously reported in Hasselquist et al. 2018 Part 1 Test Methodology. The results are reported herein, Part II Data Analysis Cognitive results showed that performing a road march wearing CIE degrades cognitive control processes, primarily response inhibition. Human factors results showed that the Load Effects Assessment Program LEAP obstacle course and both static and dynamic marksmanship scenarios are sensitive to difference in equipment configuration, whereas the Military Operations in Urban Terrain MOUT exercise was sensitive to differences in configuration for measures of mobility, but not lethality or decision making. Biomechanics results showed that measurement techniques could be successfully implemented in field settings, and that measures such as inertial measurement unit IMU derived performance degraded with heavier body-borne loads. Together, the results suggest that physical and cognitive measures of Soldier performance change as a function of CIE, and that the present operationally-relevant scenario is sensitive to detect such changes.
