Have there been any conclusive studies regarding athletes and amount of sleep needed?

Question

I'm looking for some statistics or studies regarding the relationship between the hours of sleep one gets and their athletic performance?

Perhaps I wasn't clear enough- I am looking for factual studies, not opinions here. Thank you.
