The anabolic window last between 45 minutes and 3 hours. Where did you get the information that last 24 hours?

No problem...see the link above for the anabolic window information.
I think what you're referring to is the optimum window for replenishing glycogen using simple sugars, which is described in detail here:
Nutrient TimingKey text:
Post-exercise (within 30 minutes) consumption of CHO at high dosages (8 – 10 g CHO/kg/day) have been shown to stimulate muscle glycogen re-synthesis, while adding PRO (0.2 g – 0.5 g PRO/kg/day) to CHO at a ratio of 3 – 4:1 (CHO: PRO) may further enhance glycogen re-synthesis.In reality, this is simply a window of
opportunity, not a window of
necessity. If you don't consume carbs in the first 3 hours, you can still get the same affect by consuming them later; you're just better off eating whole food as opposed to drinking a simple sugar drink.
The anabolic window is much greater than the 3 hours indicated. Muscles require 24-48 hours to repair themselves, and they're using nutrients to do so the entire time. There is no critical timing outside of ensuring you're consuming enough protein over a 24-hour period to support muscle repair and synthesis.
That said, if you plan to do another training session or serious manual labor within 8-10 hours of your workout, a recovery drink is probably a good idea. Otherwise, you get the same benefit from eating whole foods, which are undoubtedly more nutritious.
Hope that helps!
