Abstract: High carbohydrate intake is essential to maintaining prolonged endurance performance (Coyle et al., 1986). The form in which carbohydrate food is ingested alters the glycemic response to that food (Crapo and Henry, 1988. Therefore, the purpose of this investigation was to examine the metabolic and performance effects of ingesting solid compared to slurried carbohydrate food (bananas) between two prolonged exhaustive exercise bouts. Eight highly trained male triathletes participated in this study. Subjects mean (±S.E.M.) age, weight, percent body fat, running V02max, and cycling V02max were 25.7±1.1 years, 68.3±3.0 kilograms, 9.8+1.5 %, 68.1±1.9 and 67.1±2.6 ml/kg/min, respectively. Subjects performed three exhaustive endurance tests (ET), each separated by at least two weeks. Each ET consisted of a 90 minute run followed by 90 minutes of cycling, both at 70% V02max. Workloads were then gradually increased on the cycle, such that by 15 minutes the total increase in work equaled 200 kpm. Subjects continued to cycle until exhausted.
