Effects of 12 Hours of MOPP (Mission Oriented Protective Posture) IV Gear on Cognitive Performance under Non-Exercise Conditions

摘要

Twenty-four U. S. Marine Corps personnel performed computer controlled tasks during 12 one hour periods, with and without full chemical warfare protective gear. Decreased speed and accuracy was found in the performance of various tasks. Most of these changes were present within the first four hours of testing. Many more changes were seen than in a previous study where the M17A2 mask was used alone in a four hour protocol. The results suggest that chemical protective clothing may interfere with performance even in sedentary activities and that the predominant problem comes from factors other than the mask.
