Summary

A randomised counter-balanced intervention study in endurance athletes

Detailed description

To characterise glycaemic, dietary, physiological, and metabolic responses around intense endurance exercise and training in ultra-endurance athletes. Primary objective • Detail the proportion of time spent in glycaemic ranges over a prolonged period of training under the influence of different GI diets in Ultra-endurance athletes. Secondary Objectives * Characterise physiological responses to differing GI diets during a period of extensive endurance exercise through hormonal markers. * Observe the influence of differing GI diets on the impact of endurance performance and short term recovery from endurance exercise, detailing the influence of different GI carbohydrate on the restoration of performance output. * Observe the perception of wellness and gut discomfort using either high or low GI diets supplemented with high or low GI carbohydrates.
