Nutrition for a sprinter

Is fat the optimal fuel for sprinting, or should I be adding in some starchy carb (like a sweet potato) before I train/compete?

Cheers,
Adam

Re: Nutrition for a sprinter

Fat adaptation as a primary fuel source takes 1-3 weeks it seems so I wouldn't just switch all of a sudden.

No, carbs are the optimal fuel for sprinting and all other forms of high intensity athletic activity.

Re: Nutrition for a sprinter

Carbs, but it doesn't need to be 65%. I do just fine on 25% carbs, mostly sweet potatoes, fruit, and squashes. ~15% protein and 60% fat. Largely going to depend on your training and competition schedule, but this keeps me well fueled up for training, but I'm fat adapted for all lower intensity stuff.

During competition, coconut water (you can find it at Whole Foods) with a small amount of protein seems to help between events if there's time. Last track meet this year, I long jumped, then ran the 200m and had about 90 minutes before the 100m, so I had some coconut water and a couple slices of prosciutto. Saved the real grubbing for right after the 100m.

So does this mean that one would have to completely cut out fruits as well?

Re: Nutrition for a sprinter

I'm stating that from the studies of changing from a typical diet to Inuit diet. It took them about 1-3 weeks to get used to it. They probably didn't have any fruit. Dunno. One of these was on some trek across Canada and another I think was when a researcher decided to try to see if their diet was viable.

I suspect that you're referring to Phinney's study Ketogenic Diets and Physical Performance (wfs) which concluded that "submaximal endurance performance can be sustained despite the virtual exclusion of carbohydrate from the human diet" but that "anaerobic (ie, weight lifting or sprint) performance is limited by the low muscle glycogen levels induced by a ketogenic diet, and this would strongly discourage its use under most conditions of competitive athletics."

It was an native village decided to look at their high rates of diabetes and CVD problems and the sideline problems of Renal disease. So it pushed for a more traditional native with some western foods allowances.

Re: Nutrition for a sprinter

Daryl and Frank, it was from a few urls off of PM but not those exact articles to mind. Close, I think. I have them on my desktop as mht files to be printed out in the gym but I would have to refind the urls.

I think if an athlete was already fat adapted, it wouldn't pose a problem but if they weren't, it may or may not work.
