I wonder how many of the runners in these studies also did these activities as well? I guess what I am saying is is this a comparison between active and inactive elderly or active runners and active non runner elderly. It would make a big difference in evealuating whether the act of running itself not just a higher activity level had anything to do with the resistance to age related deterioration.
This may not be quite what you are looking for, but here is a study of Finnish elite athletes, with a ranking of longevity vs sport group (endurance, team, or power athletes). I didn't notice any data pertaining to how long these athletes continued their activity or what other activity they participated in, although as elite athletes its doubtful they did little if any athletic activity outside their specialties:
The conclusion: endurance athletes had the highest life expectancy.
