Mouth Rinsing With Branched-Chain Amino Acids And Carbohydrates On Steady-State Metabolism, Exercise Performance, And The Endocrine Responses To Exercise, Zebblin Matthew Sullivan

Graduate Theses and Dissertations

Previous research suggests that mouth rinsing carbohydrates (CHO) improves exercise performance. The mechanisms for the improvement are not yet known, but may involve maintenance of insulin concentrations during exercise or attenuation of centrally-mediated fatigue from putative, caloric-responsive receptors in the oral cavity. The purpose of this study was to determine the effects of mouth rinsing branched-chain amino acids (BCAA) or CHO on cycle time trial performance, blood markers of central fatigue (prolactin), plasma insulin, glucose, and lactate concentrations, substrate oxidation during steady-state exercise, and the subjective exercise experience. Ten healthy, endurance-trained adult males (23.5 y 3.8 y, 74 ...
