In your 200+ sample, eight died. Certainly that's more than the seven deaths in 570 light joggers, but we really are stretching the meaning of statistically significant when we work with such small numbers. The tiniest factor that wasn't accounted for could easily make the difference.
Also, given the time period of the study, it's likely there's a great reliance on self-reporting of activity level. Doing the same study today, over ten years should be possible with a much better data set thanks to apps like Strava, MapMyRun, etc.
