A MECHANISTIC COMPUTER-SIMULATION OF HUMAN WORK IN HEAT THAT ACCOUNTSFOR PHYSICAL AND PHYSIOLOGICAL-EFFECTS OF CLOTHING, AEROBIC FITNESS, AND PROGRESSIVE DEHYDRATION

1. This paper describes a computer model (SCENARIO) specifically desig ned to simulate the time course of heat strain observed during athleti c, industrial, and military settings. 2. The simulations generated by the model dependably reproduce the time course of body temperature shi fts, thermoeffector responses, central and peripheral circulatory chan ges in persons exercising in warm and hot environments. 3. The model t akes into consideration different clothing ensembles, varied levels of aerobic fitness in a population, and effects of progressive dehydrati on and deconditioning (extended bed rest).
