A substantial amount of research on pre-exercise nutrition suggests that carbohydrate ingestion prior to exercise and sport activity increases performance due to various factors like blood glucose maintenance, better-facilitated carbohydrate breakdown, and higher glycogen turnover. PURPOSE: The purpose of this study was to determine if a high-carbohydrate pre-exercise meal allowed sedentary and recreationally active people to produce higher peak anaerobic power outputs in watts than if they consumed a high-fat or high-protein meal. METHODS: Five male and four female college students at the University of Central Missouri, who identified as sedentary or recreationally active, were recruited to consume a high-fat, high-carbohydrate, or high-protein meal at three different sessions. Participants were instructed after feedings to return to the lab approximately 180 minutes later to perform a 30-second maximal power output test known as the Wingate Anaerobic Test. RESULTS: The results showed peak anaerobic power outputs were highest for the fat trials at a mean of 847.78 ± 278.52 W, followed by a mean 832.22 ± 224.39 W for the carbohydrate trials, and a mean of 801.67 ± 245.41 W for the protein trials. CONCLUSION: The hypothesis that peak anaerobic power output in watts would be higher following the consumption of a high-carbohydrate meal compared to a high-fat or high-protein meal was not supported by the data. Although the mean peak anaerobic power output in watts was highest for the high-fat meal trials, only four subjects performed their best trials after the high-fat meal.
