Abstract:Introduction: Carbohydrate (CHO) availability sustains high metabolic demands during prolonged exercise. The adequacy of current CHO intake recommendations, 30-90 g•hr-1 dependent on CHO mixture and tolerability, to support elite marathon performance is unclear. Purpose: We sought to scrutinize the current upper limit recommendation for exogenous CHO intake to support modeled sub-2-hour marathon (S2M) attempts across elite male and female runners. Methods: Male and female runners (n = 120 each) were modeled fr… Show more
