I imagine that you mean competitively, like in the olympics or other events/competitions like that.
Unfortunately I don’t have an answer about that.
When I was in rehab. there was a woman that played on a competitive wheelchair basketball team. It surprised me that she would play wheelchair basketball since she was walking around and looked perfectly fine to me. It turned out that she was missing her foot and the lower part of the leg, so she used a prosthesis. She moved fine, and her movement looked natural. If she hadn’t told me, I wouldn’t have known the difference.
So thinking about that, it’s just a guess, but I don’t think someone that is fully functional would be allowed to compete with people in wheelchairs in the paralympics or the NY Marathon. I know that for some competitions they break up the athletes into different divisions by the level of function. T5’s won’t compete against the T12’s.
Of course anybody could play a sport in a wheelchair, but I would question the mental state of anyone without some kind of disability that just wanted to compete in a wheelchair to beat on all of us that really have to be in one. (Hypothetical, I know. I’m just saying.)
