Abstract : This study found that the decrements in physical work performance caused by wearing an NBC protective uniform (U.S. Army Mission Oriented Protective Posture IV) are greater at intermediate (2,743 m) and high (4,300 m) terrestrial altitudes than at sea level. Concurrently, the study demonstrated that staging at moderate (1,830 m) altitude improved work performance in an NBC protective uniform at intermediate and high terrestrial altitudes. In addition to decrements in physical work performance, rapid ascent to intermediate altitude degraded marksmanship performance. However, following staged ascent, marksmanship performance was improved at intermediate altitude. The results of this study validate previous recommendations regarding the employment of a staged or slow ascent to minimize decrements in work performance and extend those recommendations to operations in NBC protective uniforms at intermediate and high mountain altitudes.
