The studies I've referred you to are the largest, the most rigorous that have ever been done to date on the topic. They are not "observational garbage".
>You can use google as well as I can.
Well, that's the thing. My knowledge comes from readining actual journals and having doctors in the family who can interpret them. You're the one googling "runners die young". In fact, the actual study behind your NYT link paints a different picture than the NYT article did. See the conclusion:
"We conclude that SIT is a time-efficient strategy to elicit improvements in peripheral vascular structure and function that are comparable to ET. However, alterations in central artery distensibility may require a longer training stimuli and/or greater initial vascular stiffness than observed in this group of healthy subjects."
I repeat, Can you refer me to any peer-reviewed research linking sprint training or weight training with equal or greater benefit in any of the health indicators that Paul Williams's 100,000 person study found distance running improved? I seriously doubt it, because I've scoured every journal I have access to for comparative studies, and every one of those studies found greater longevity and fewer lifestyle diseases in endurance athletes than in speed or power athletes.
