I hate to get into foolish arguments... we all know there is a world of difference between an athlete an Rosie O'Donnel. but, here you go:

Athlete: a person trained or gifted in exercises or contests involving physical agility, stamina, or strength

Now, if all it takes to be an athlete is to contend for a prize, why are we getting our panties in a twist over the Olympics when all we have to do is tune in 'The Price is Right"?
