No. I'd have thought most (all) AFL clubs offered guidelines only.
I can remember an article on the life of an AFL player from years ago, based on Freo. It discussed all the things we all alresdy hear about - healthy diet, strategic carb loading, skin-folds and the like. But it was hardly revolutionary even back then.
How would he know though? Do we assume there are as many as 18 different ways to do this, and that one is measurably better?
But why?
