I watched a vid attempting to explain this once, dont have it on hand and don't know how accurate it is.
From what i understand, part of it is cultural. Meaning typically they are the ones into tgat sport. But it said patt of it is ankle and wrist size as well as types of muscle fibers in joints which is typically different.
