Abstract

An endurance event requires the athlete to maintain high levels of substrate oxidisation for a prolonged period of time. The intensity of the event impacts on the substrate which will be consumed to maintain such pace. Carbohydrate utilisation is the preferred source of substrate for high intensity performance however its presence is limited in the human body. Therefore methods to optimise the use, or ‘sparing’, of such a precious substrate is of great importance when the event demands a large consumption of energy. Consumption of exogenous carbohydrate to supplement endogenous stores is universally accepted as a method to maintain high intensity performance. What is less commonly recognized is the method by which the exogenous carbohydrate is consumed and if mode of supplement, i.e. gel or solid, affects substrate oxidation. Or during ‘real life’ events what effect other important factors, such as fluid consumption, have on overall performance. The other method to optimise endogenous carbohydrate stores is to up-regulate more abundant energy stores such as fat oxidation. Further work is required to evaluate this theory in relation to endurance performance.
