Under which conditions are sportspeople eligible to compete at Universiade?
Additionally, I also wonder to which extent it is common that same person represents a country at both world championships and universiade.
I have tried to Google for universiade olympic medal site:wikipedia.org to see whether I find some people who won medals at both Universiade and Olympic games. Going through the first few pages of results of that search I have noticed Javier Sotomayor and Amanda Beard.
My guess is that this is less common in the most popular (and best paid) sports such as football, ice-hockey, basketball. (I suppose that not many players would risk injury at a less prestigious event. I am also not sure about the collision of the dates with other competitions; professional teams probably would not be willing to let an important team member to leave their professional team for Universiade.) However, I do not have any data to support this guess.
