To date, there have been no published studies that have examined if feeding protein alone has any differential effects than carbohydrate feeding on exercise performance, perceived exertion or biochemical markers and hormonal response to both the exercise and feeding itself. Thus in a randomized double blind crossover controlled clinical trial, eight subjects were evaluated to determine if feeding &sim;40 grams of protein as compared to carbohydrate or a 2:1 protein to carbohydrate formula (mix) to a glycogen depleted athlete had any differential effects on exercise performance, perceived exertion, anabolism and catabolism. After following a glycogen depleting diet (low carbohydrate), subjects performed graduated resistance leg extensions for 150 total repetitions (depletion of glycogen in the vastus lateralis). Subsequent to the exercise, subjects rested for 20 minutes while ingesting the assigned drink. All subjects than proceeded to undergo three sets of repetitions to failure of leg extensions at 70% their 1-RM. A two-way repeated measures analysis of variance (RM-ANOVA) to analyze product, time and product x time coupled with paired Students T test where appropriate and the linear mixed model was employed to determine if a treatment was significant at any time point or over-time. There were no significant differences amongst the three test groups for exercise performance, perceived exertion, or markers of protein synthesis. Thus it appears that within the confines of this study, feeding a glycogen depleted athlete a pure protein, carbohydrate or mixed macronutrient beverage will not have any differential effect on subsequent athletic performance, perceived exertion or acute muscle protein synthesis or injury. Continued studies are warranted.
