Glucose is the body’s preferred fuel. It comes from the breakdown of the carbohydrate we consume and is the predominant energy source for high intensity activities lasting from 30-seconds to approximately 90-120 seconds, such as performing a set of 8-20 repetitions of a resistance exercise at a high intensity, or 30 second maximal sprints.
Glucose disposal agents (GDAs) are substances that aid the uptake of glucose from the blood stream into the muscle tissue where it can be used immediately to fuel activity, or can be stored in the muscles and liver as Glycogen to provide energy when needed later. GDAs increase muscle cells sensitivity to Insulin therefore reducing the need for high levels in the blood and helping to ensure that the carbohydrate we consume is used as fuel for activity, rather than stored as body fat, and so potentially enhancing performance, recovery, and Body Composition.
