Influence of high and low glycaemic index carbohydrate meals on exercise capacity and substrate metabolism in men

Ingestion of carbohydrate (CHO) before exercise and after exercise enhances subsequent endurance exercise capacity when compared to a fasting state. However, the optimal type of CHO meal to be consumed is still unclear. Glycaemic and insulinaemic responses to a meal during the postprandial period may play an important role in subsequent exercise metabolism and performance. This thesis examined the influence of ingesting high and low glycaemic index (GI) CHO meals three hours before exercise and during four-hour recovery on substrate metabolism and exercise capacity in men.
