What does that mean, preventing stress adaptations? Does it mean that the body wouldn’t get stronger in training ?

Right. Some of these potential longevity interventions seem to have a catabolic effect. Not a problem if you're a mouse living in a safe, flat lab cage. But problematic for an elderly human at risk of falling down the stairs and breaking a hip due to sarcopenia.

Is it strong enough to actually cause that, or is it the kind of thing nonathletes won't notice?

Or is the life extension effect too subtle to be relevant at all outside a flat mousecage?

That is really interesting. I hadn't heard that, but it makes a lot of sense.
