There are two main energy systems utilized in the human body during endurance exercise. Glycogen and fat. The two fuel tanks are accessed under a variety of conditions.
Glycogen is the anaerobic rocket fuel tank while fat is your more stable aerobic fuel tank.
When performing exercise at high levels of intensity the oxygen supply to the human body becomes way more demanding and the ability to utilize fat as a source of fuel is negated.
Glycogen becomes the primary fuel source to support these harder efforts. The glycogen fuel tank is limited to approximately 2000 Kcals meaning that energy expenditure over time at a hard effort can deplete the energy supply.
In order to avoid this a rapidly releasing and absorbing carbohydrate supply would be required to slow down the rate of depletion allowing longer exercise duration at harder efforts.
32Gi Race does exactly this. It is a high calorie quick releasing provisioning carbohydrate feed whose sole purpose is to spare glycogen and allow for much bigger exercise performance over a longer period-of-time.
