| Abstract: | (U) We evaluated the effect of carbohydrate loading (TEST) vs control diet (CON) on the thermal status and the ability of 8 U.S. Navy divers to perform intermittent leg exercise at 80% max Oxygen 2 consumption during head-out immersion in 25 deg C water. Each subject was tested once after 3 days of the TEST diet (600 grams carbohydrate/day and once after 3 days of CON diet (less than 300 g carbohydrate/d). The TEST diet included 200-400 grams of glucose polymer solution (GPS). Both diets were nutritionally complete and provided 3000 Kcal/d. A pattern of 10 min rest/20 min work was repeated until the diver could no longer complete a 20-min work session or until 8 sessions had been completed. Divers completed more work after TEST than CON. Four completed all 8 work sessions after both diets; 3 completed all sessions after TEST, but not CON; one completed 7 sessions after TEST and 6 after CON. Differences between diets for O2 consumption, CO2 production, and minute ventilation were not significant.
