Research Objective: The specific objective of this study is to contrast three different oral rehydration solutions (sports drinks) during a prolonged exercise trial on muscular strength, speed, and endurance in healthy young adult males.

Methodology: Thirteen (13) healthy male subjects will participate in a 5-mile walk on an outdoor track carrying a 40-pound rucksack on three separate occasions while drinking one of three (3) oral rehydration solutions (sports drinks) at a rate of 250 mL every 15 minutes as recommended by the American College of Sports Medicine. All three trails will be performed outdoors and differences in environmental conditions accounted for by balancing all three treatment groups on each of three days of testing. The three sports drinks that will be used are CeraSport® (a rice-based carbohydrate/electrolyte drink), Gatorade® (a commercial carbohydrate/electrolyte drink), and Ultima® (a commercial electrolyte drink without carbohydrates). The subject’s hydration status will be assessed pre- and post-exercise using changes in body weight, urine output, and temperature change. Muscular strength will be assessed following the 90 minutes of exercise with three sets of pushups to exhaustion. Sprint performance will be measured as the mean of three 40-yard dash trials, and finally, subjects will run a timed mile to assess endurance capacity.
