Athletics teach you how to move smoothly and from your center. The modern study of athletic movement (as one would find in football, basket ball, track and field etc) teaches any of the things I can think of that are learned in "internal". The language is different but the lessons are the same. It's hard to go into anymore detail without further understanding your knowledge of sports training.
I don't know of any athletic training that teaches coordination of ki through intent to move the body. Could you tell me where they're doing that?
