Core Temperature and Surface Heat Flux During Exercise in Heat While Wearing Body Armor

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 (n=9), dressed i...

Zusammenfassung:	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 (n=9), 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.
