ABSTRACT
The physiological and cognitive performance of acclimatized soldiers undertaking routine patrol and reconnaissance activities in the tropics was investigated. Data were obtained during a patrol and a reconnaissance exercise followed by a short assault. Ambient conditions were characterized by temperatures of 30 to 33 degrees C, low humidity (52-59%), and moderate to high solar radiation. Maximum metabolic rates during patrol were high, although the equipment carried was modest and the terrain was not severe. Rectal temperatures peaked at 38.2 and 38.4 degrees C for patrol and assault activities, respectively; peak heart rates were 160 beats min-1 for each activity. Sweat rates of approximately 9 and 14 g kg-1 body weight h-1 were recorded for patrol and assault activities, respectively. The soldiers maintained adequate hydration levels and displayed no evidence of deterioration in cognitive performance. The data show that routine operational activities in tropical conditions induced physiological strain in acclimatized soldiers. However, this strain was not maintained at hazardous levels for lengthy periods.
