You DO NOT want high GI carbs (glycoload) prior to training. It will cause a wild swing in insulin levels and blood glucose levels that will leave you very lethargic once the glucose is cleared from your blood stream. Because it (glycoload) is a high glycemic index carb it will enter the blood stream very quickly and thus facilitate a sure in insulin to clear this glucose from the blood stream. A large amount of insulin, known a a "spike", will be secreted from your pancreas to deposit the glucose where is is needed (or sometimes where it is not needed as in the case of adipose tissue). Once the glucose is cleared from your blood you will become tired, irratable, and fuzzy headed. This is because there is very little circulating glucose imidiately after the glucose is cleared and being that yhe brains fuel is glucose it will be running on "low"...until you provide it with more glucose. This is why you should be consuming low GI carbs prior to training and really at all meals except post training. Low GI carbs are "slow release" and as such provide for steady levels of glucose in the blood that can sustain fuel needs for prolonged periods of time as oppsed to a quick hit of glucose as in the case of high GI carbs. Stick to oats, sweet potatos, brown rice, legumes, barley, whole grain breads, and some fruits(though not really ideal).
