CARBOHYDRATE SUPPLEMENTATION AND PERFORMANCE
Anantaraman, R., Carmines, A. A., Gaesser, G. A., & Weltman, A. (1994). The effects of carbohydrate supplementation on maximal effort endurance performance. Medicine and Science in Sports and Exercise, 26(5), Supplement abstract 34.
Pre-exercise ingestion of a glucose polymer solution (30 gm in 10% sweetened) resulted in less drop-off in power output during one hour of maximal effort endurance performance than did a placebo. No further benefit was observed when the same amount of glucose polymer was ingested every 15 min during exercise.
Implication. Glucose polymer ingestion prior to endurance exercise can benefit performance. There is no benefit taking it during performance.
