Research in the first area has been concerned with physical performance, primarily of athletes. Research results have demonstrated that even small fluid deficits have adverse effects on performance through elevated heart rates, reduced sweat rates, and elevated body temperature.

The maintenance of adequate fluid intake is of primary importance in the prevention of hypohydration that may otherwise occur under such conditions as prolonged air travel, extended working hours, wearing of chemical protective clothing, missed meals, or working in mountainous areas or in hot or extremely cold environments. Increased psychological stress associated with basic or field training exercises or anticipation of combat or actual combat may lead to extreme hypohydration due to decreased voluntary fluid intake.

The resultant reduced muscle and liver glycogen content will result in earlier fatigue and slower recovery. It is evident from the research reported at this workshop that a fluid replacement solution may play an important role in preventing fluid, electrolyte, and glycogen depletion, thereby maintaining or improving a soldier's performance.

the factors that are important in preventing muscle injury during heat stress and in enhancing muscle recovery. The following issues raised at the workshop could lead to a better understanding of the appropriate composition and usage of a fluid replacement beverage: · What are the effects of food in the small intestine on fluid and electrolyte absorption?

Replacing gastrointestinal losses due to vomiting or diarrhea! The committee recommends that the Surgeon General of the Army evaluate the use of electrolyte-carbohydrate fluid replacement products as an aid to maintaining proper hydration of soldiers during periods involving psychological and environmental stress and also assess the effectiveness of these products in maintaining or enhancing both physical and cognitive performance during training activities and field operations.

From page 144... ...
The value of additional magnesium, bicarbonate, and phosphate to compensate for gastrointestinal losses due to diarrhea or other gastrointestinal disturbances should be determined. · The promotion of fluid intake with such palatability and psychogenic aids as flavorings and colorings should be evaluated with respect to the promotion of fluid intake.
