Professional atheletes, what are the rules?

[weltweit]

I thought atheletes at the Olympics usually had to be amateurs but this is patently not true as there are professional tennis players and professional footballers in the olympics.

I was pretty sure in boxing they have to be amateur.

Are there any blanket rules or is it just a muddle?

I don't know, but I'm going for the muddle option.
