Physiologic tolerance to uncompensable heat: intermittent exercise, field versus laboratory

Article Abstract:

This article examines the effects of exercise and rest cycles on physiological response to heat-induced stress. Findings indicate that ten minute rest periods between exercise sessions did not affect heat-stress tolerance or core temperature at exhaustion, but participants in field trials demonstrated higher tolerance levels than participants in laboratory studies.

The effects of continuous hot weather training on risk of exertional heat illness

Article Abstract:

The cumulative daily average wet-bulb globe temperature (WBGT) index, over one or two preceding days, is a better measure for predicting cases of exertional heat illness (EHI) than current daily average WBGT, which is the standard heat index used by the Marine Corps. The results provide a simple index for use in predicting EHI risk that includes the dry-bulb temperature and the relative humidity.

Epidemiology of hospitalizations and deaths from heat illness in soldiers

Article Abstract:

The hospitalizations and deaths from heat illness for the entire active duty US Army during the calendar years of 1980-2002 were examined and were considered as one of the largest and most comprehensive epidemiological study of exertional heat injury. It is concluded that exertional heat illness continues to be a military problem during training and operations and found that heat stroke has markedly increased whereas the hospitalization rate of heat illness is declining.
