Carbohydrates are used by the body as fuel during exercise; eating or drinking a small amount of carbohydrate before or during exercise is beneficial in some circumstances. The amount, type, and timing of carbohydrate have been researched in the past, but more data is needed to formulate an ideal plan for consumption around exercise. A product called ModCarb has been developed from grains thought to inhibit the blood glucose lowering reaction. The present study tested pre-exercise consumption of ModCarb with and without added protein, for effects on aerobic exercise performance in moderately trained male subjects age 18-30. Seventy-five subjects were randomly divided into five groups, including placebo, ModCarb (3grams), ModCarb&amp plus whey protein (3 grams, 14 grams), whey protein (14 grams), and whey protein plus sucrose (14 grams, 20 grams) to provide additional Calories more similar to that found in commercial sports beverages. Subjects completed two exercise testing sessions separated by 10-21 days which assessed time to complete a three-mile run, distance covered in a 25 minute stationary bicycle activity and number of steps completed in a 90 second step test. A one time consumption of the product(s) resulted in improved run time within all groups including placebo except the protein plus added sugar group. An improvement in the step test was seen for all groups (one-tailed paired t-test, p-value = 0.05). There was also an improvement in bike distance seen for all groups except the Modcarb group (one-tailed paired t-test, p= .05). None of the supplement combinations resulted in improved aerobic exercise performance in any of the groups compared to placebo (unpaired t-test, p-value = 0.05). No significant changes in plasma glucose levels were seen between baseline and treatment sessions within the groups (paired t-test, p-value = 0.05), and there was no overall change in plasma glucose comparing each group to placebo (unpaired t-test, p-value = .05). Possible confounding factors such as hydration status, intrinsic motivation and familiarity with the testing protocol may have contributed to the improvement in aerobic exercise seen within the groups. The amount of ModCarb supplement provided to each group may also need to be increased to see more significant effects. In conclusion, a one-time consumption of ModCarb in the amount provided did not improve aerobic exercise performance or change plasma glucose responses following exercise.
