Effect of a novel carbohydrate blend on exogenous- and endogenous-carbohydrate utilisation and high-intensity endurance performance : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Nutrition and Dietetics at Massey University, Auckland, New Zealand. EMBARGOED until 14th March 2026

Abstract

Background: Ingestion of fructose and glucose/maltodextrin at ratios close to unity during high-intensity endurance exercise enhances exogenous-carbohydrate oxidation and endurance metrices, relative to single carbohydrates or fructose-glucose/maltodextrin blends at different ratios. This thesis explored the effects of other carbohydrate blends on metabolism and performance.--Shortened abstract
