Abstract :
Beginning in the summer of 1999, NEDU began a three-year study to determine the basic physiologic response of divers at exercise in water temperatures from 34.4-38.6°C. The goal was to determine physiological limits as a function of core temperature (as measured by rectal temperature), physical and cognitive performance, and various biochemical markers of muscle stress vs. time. Phase I (1999) used heat acclimated divers wearing only swimsuit and T-shirt. Phase II (2000) used heat acclimated divers and compared different types of diver dress: swimsuit, "dive skin," and dry suit. Phase III (2001) compared cycle ergometer exercise to finning exercise under various diver dress and temperatures. Based on the results from Phase I and II of this study, interim guidelines were promulgated to all U.S. Navy diving commands
