well, you might be able to find some astrologers who studied a martial art of some sort, but beyond that they aren't.
martial arts and dance aren't really related either, but i read an article, about a few martial artist who sought out a karate 'master' and they asked him to show him some of his techniques, so stood up, and began to dance, when the students said he had gone crazy, he demonstrated a different technique from the dance on each of them. kata, was created to hid techniques and be able to pass training off as dance, but thats about the only way i can think of how martial arts and dance are related.
