Carbohydrate-Electrolyte Solution during Military Training. Effects on Physical Performance, Mood State and Immune Function
Abstract
The purpose of this study was to determine whether CRO-E beverages improve mood state and performance of military tasks. A second purpose was to examine if CHO-E solutions alter immune cell responses. Twenty seven volunteers were randomly assigned to one of three groups: CHO-E beverage, placebo or water. Fluid intake for all groups was ad libitum; food intake was restricted to 2600 kcal.day. Subjects completed 2 days of field training in warm (300C), humid (60%rh) conditions. Each day included a 14.5-21 km march over hilly terrain, marksmanship training and 2 h of rock climbing. On day 3, a circuit was completed consisting of a 14.5 km march, marksmanship, rock climb and 1.3 km uphill (21% grade) foot race. There were no differences (P<O.05) between the three groups for either absolute values or changes from pre-training values for fluid intake, body weight, climb time, run time, marksmanship or mood. CHO-E resulted in less increase (P<O.05) in white blood cells and granulocytes. There was, however, no difference in lymphocyte proliferation response between CHO-E and water before, during or after field training. It was concluded that drinking CEO-P beverages does not improve physical performance of military tasks.
