Abstract:

This study provides a dataset for model development, refinement, and validation. Control data from test volunteers exercising without body armor will facilitate the development of non-invasive estimates of core body temperature Tcore. Basic test design consisted of test volunteers n9, dressed in combat clothing and equipment, with body armor, conducting two 1 hour treadmill walks at light-to-moderate 347 - 28 W and moderate-heavy 537 - 28 W work rates separated by 30 min breaks. Activity was bracketed by pre- and post-walk rest periods. Three chamber conditions were warm-neutral 25C, 50 RH, hot-humid 35C, 70 RH, and hot-dry 40C, 20 RH. Tcore was measured using two telemetry pills one was ingested and one as a suppository. Other data included height, weight, HF and skin temperature from 6 locations forehead, sternum, pectoral muscle, scapula, rib, thigh, heart rate, and metabolic rates.
