If you are talking about weekly practices, yes they change your ratings temporarily. Practice on what you think is lacking on your team using "normal" intensity every day. I do all of them as much as I can, focusing more on the ones that increase the most ratings, like defense, close range, fast break, and shootaround when I don't have enough days off between games. I like to give them a day off every few days, but I am not sure if that matters since their fatigue seems fine after one day of "normal" practice intensity. I don't like "intense" practices since they cause alot more fatigue which the players need several days to recover from and it only increase the ratings by one over a "normal" intensity practice.
Beware of practicing too much because it really inflates your players ratings and cause them to think they should have a better role and more minutes, lowering their morale and ratings.
There was a bug in the development drills that caused some ratings to decrease, but I don't remember it being in 2K9, only in 2K10.
