Abstract  Peri-workout carbohydrate and protein supplementation has become an increasingly popular strategy amongst athletes looking to increase athletic performance. Mounting evidence over the recent decades has demonstrated the performance-enhancing effects of carbohydrate intervention, especially in cases of prolonged exercise. Recent advancements in food science have led to the creation of designer carbohydrates, including highly branched cyclic dextrin (HBCD). Due to the physical properties of HBCD, these molecules undergo a unique metabolism that may elicit performance advantages over simple carbohydrate sources during exercise. When combined with amino acids, this protein-carbohydrate mixture may be the most current and up-to-date peri-workout supplement protocol...
