I was a martial artist when I started skydiving and I think it helped me. Ironically, my instructor had studied one of the same arts as I and he used several martial arts metaphors to help me in my A training.
I did pretty well in freefall, but landing was always a challenge for me. I think martial arts training has helped me survive some pretty bad landings though.
Its also a good sport for bad weather days. I do both sports now and I think they make a great combo.
