I'm going by recollection, but google "running CVD" and it should pop up several. What that won't show up are the commonalities with cycling, which is what lead me to abstract out the "cardio-vascular fitness" that keeps popping up as the major correlating factor. That's not the same as "more healthy" by the way, but it does correlate with better health.
