Abstract

Intra- and inter-individual , as well as group, variability of a Modified Craig index of physiological strain and body heat storage was determined and their relationship defined for 5 sitting, nonacclimated subjects wearing 1 clo body insulation and exposed 5 times to each of the heat stress levels: 38° C, 54° C, and 71° C at 10 mm Hg vapor pressure. A linear relationship between physiological strain and thermal stress range studied is shown, although individual variation is marked, especially at higher stress levels. A statistically significant correlation between strain index and body heat storage is show. Individual and mean variations in heart and sweat rates, and skin, rectal, and body temperatures as related to body heat storage, are illustrated. Data show usefulness of the correlation between strain and heat storage in comparing overall strain resulting from exposure to dissimilar thermal environments for different periods of time.
