Oh cool! The estimate of an actual MET level for best longevity is great! It seems reasonable too, 10 is pretty hard to sustain. I would have been suspicious of a lower number. They also note some limited evidence that intermittent vigorous exercise with full days off seems to be better than daily exercise. This matches the current model of vigorous exercise as a eustress, where the recovery is what is important.
WRT the elite athletes, the discussions I’ve seen of reverse causality seem fairly convincing. Those people were going to live longer regardless of their chosen profession, so it’s hard to tease out what specifically the additional benefit of exercise was. (IIRC there was a twin study that looked at pairs with one becoming a pro athlete and the other not.)
Sorry about the broken links. Anyways, IIRC, The Mayo Clinic proceedings only recommend limiting vigorous exercise. Do you think one could still get more health benefits by exercising non-vigorously? i.e. They recommend limiting vigorous exercise to ⇐ ~50 MET/wk (assuming the exercise burns 10 MET/hr). Do you think one would get additional health benefits for exercising moderately for, say, 100 MET/wk?
At some point the stress effects cross the exercise effects in size. That crossing might be slightly different for different people, but for most even 5 hours/wk is a big ask. An additional 100 MET per week seems like it would be pretty disruptive to trying to lead a normal life, hold down a job, and socialize. I think some people become addicted to exercise and do it to a fault.

I’m surprised there are that many matching twins floating around.
4/1000 means they’re not that rare.
No, but we aren’t exactly brimming with pro athletes either.
