A new carbo-loading regimen developed by scientists at the University of Western Australia calls for a normal diet with light training until the day before the race. On the day before the race, the athlete performs a very short, extremely high-intensity workout (such as a few minutes of sprinting), then consumes 12 g of carbohydrate per kilogram of lean mass over the next 24 hours. The regimen reportedly resulted in a 90% increase in glycogen storage.
Carbohydrate loading is generally recommended for endurance events lasting longer than 90 minutes. For many endurance athletes the food of choice for carbo-loading is spaghetti. Because of this, hundreds of marathons and triathlons have huge spaghetti dinners the night before the race
