Doubtful, but I'm not certain. The reasoning for my answer is this: athletes need stores of glycogen in their muscles for bursts of energy and lo-carb plans are specifically designed to get rid of the glycogen stores, it's highly unlikely that you'll find any "real" athletes that really bust their butts doing a lo-carb WOL. There are books available on this topic; I paged through one at my local library just last week and this is the basic summary of the "why athletes should not do lo-carb diets" section. Maybe you will find better answers there.

Hope that helps.
