Abstract:
Some metabolic effects of a 2h exposure to an environmental temperature of 48 degrees C DB, 35 degrees C WB, have been studied in six male subjects. The results indicate that adrenal cortical activity does not necessarily increase as a result of exposure to moderate heat stress. However, a consistent increase in lipolysis may indicate increased sympatho-adrenal activity. There was a significant correlation between blood glucose and cortisol levels, suggesting that the increased sympathetic activity may be without effect on carbohydrate metabolism.
