excess mortality with high aerobic training specifically looking at the so-called J curve.

The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
excess mortality with high aerobic training specifically looking at the so-called J curve.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

there's another body of literature that says no it's more or less a monotonically improving curve and again we all agree that at one end of the spectrum having you know really poor cardiovascular fitness again we could measure this in vo2max or something like that as that improves and you get fitter and fitter and fitter and fitter all-cause mortality goes lower and lower and lower and there is no j to that curve
if you continue to increase exercising beyond a certain volume this is generally discussed in volume of exercise you actually see a little uptick in mortality suggesting that once you go beyond a certain point again i want to stress this is in volume of exercise you don't get any more benefit and you may actually have more harm and a lot of times this is harm that comes in the form of cardiac dysrhythmia it could be even atherosclerosis through endothelial damage fibrosis things like that
