Type has nothing to do with physical ability or awareness. Strong sensory experiences make a greater impression on the high Se user, while the Si user is impacted by things that are less directly sensory and more difficult to predict, but this doesn't translate into one being better at sports at all. As @spaceynyc said though, it is possible that Si users would be more likely to enjoy repetitive sports than Se users, Si seems more suited to handling repetition, as that is a cognitive thing and not a purely behaviour-based trait.
ESxJs vs ENxJs, which are better at sports?
