Simulated Approach Marches During Thermal Stress: A P2NBC2 Study
Abstract
A P2NBC2 sponsored study of eight subjects on simulated 12 mile approach marches in MOPP-0, MOPP-1 and MOPP-4 was conducted at Fort Bliss, Texas in August, 1991. The P2NBC2 objective is to study, physiology and psychology within the context of militarily relevant tasks in the NBC environment. The, focus of the present study was model evaluation, but the study included simulated marksmanship, performance In MOPP-0 and MOPP-1, and data collection for thermal features modeling. Data include rectal temperature, surface skin temperatures, heart rate, and body water loss. Subjects wore MOPP-0 and MOPP-1 CP ensembles during day and night test sessions, and MOPP-4 on one daytime session. Weather data were collected on-site and simultaneously at a remote site for development of a thermal features remote sensing program. For the daytime MOPP-1, only one subject completed a 12 mile march. In MOPP-4, the longest endurance time was 3 hours and 24 minutes. For the test scenario, heat strain at night was minimal. The marksmanship performance tests indicate a cumulative effect of time. There was general agreement, varying within an overall mean prediction error of -0.2 to 0.43 deg C, between observed subject rectal temperatures (T sub ro) and results predicted from the P2NBC2 Heat Strain Decision Aid (HSDA)....
