While I can't give you a correct or full answer to your question, I suggest you check out www.dangerouslyharcore.com and either get the book or read what Keifer has written.
Also check out this article that describes it more in laymans terms: http://www.silverhydra.com/2011/02/cheat-mode-in-depth-carb-backloading/
From what I recall from the book, men have something like a 6 hour window post resistance exercise but it is shorter for women.
