This study was designed to investigate carbohydrate supplementation during high intensity exercise and its effect on performance. Eight subjects participated in four trials; two familiarization trials, a carbohydrate trial, and a placebo trial. Fight Gone Bad Five is a CrossFit “Workout of the Day” (WOD) involving 5 rounds of 5 exercises each completed for one minute followed by a one minute rest. The exercises of the Fight Gone Bad WOD include medicine ball wall throws, sumo deadlift high pull, box jumps, push press, and rowing. Performance was measured by the summation of repetitions for the first four exercises and the caloric expenditure from the rowing session. Performance scores for carbohydrate and placebo trials were analyzed using a paired sample t-test, which found no significant difference between the carbohydrate and placebo trials.
