Abstract
Post exercise nutrition is paramount in order to replenish depleted exercise stores, mitigate muscle protein degradation, rebuild damaged muscle tissue, and have improved subsequent performance. The purpose of this study was to collect literature that investigated how post exercise ingestion of carbohydrates and proteins affected glycogen resynthesis post exercise. Collection involved only peer-reviewed literature that examined glycogen resynthesis from protein and carbohydrate ingestion post exercise, depleted glycogen stores via exercise, involved subjects who were adults and deemed healthy by preliminary health screenings. This entire review covers a total of 82 subjects with age range of 19-28, most who were trained cyclists (n = 44). Not all literature mentioned the gender number, but there were at least 64 males and 8 females. Those who were not trained cyclists were described as “endurance trained” (n=6). Literature came from by searching databases such as Researchgate, EBSCOhost, sport Discus, Google Scholar, Medscape, and Pubmed. Searches were conducted with key words such as protein synthesis, nutrient timing, anabolic window, insulin effect on protein synthesis, and nutrition effect on insulin. The results of the literature suggests that the addition of protein to a carbohydrate supplement post exercise creates greater increases in glycogen resynthesis compared to carbohydrate of equal caloric value alone when 2 hour feeding intervals. All studies that used frequent intervals (15-30 min) always resulted in greater or equal glycogen resynthesis in the carbohydrate (CHO) only group compared to carbohydrate plus protein (CHO + Pro) group.
