>It’s when you are older and/or accustomed to some kind of physical training, that you really noticeably benefit from resistance training.

Do you have any sources for that? I'm asking because that is a bold statement given the (almost non-) existing literature on pro athlete hypertophy. Especially since athletes in almost every sport don't even care about hypertrophy - unless you talk about pro bodybuilding. And there you have tons of pharmacological interventions, so it's not really easy to paint a picture either. I don't know a single good study performed on a significant set of tested natural bodybuilders regarding hypertrophy.

Studies like this are also aimed at couch potatoes, because that is the normal population, so the results will be applicable to most people, which in turn is important when you want to get funding for your research. In that sense it also doesn't matter that these people will not have reached their full neuromuscular connection compared to actual weightlifters, because most people haven't either. So the results are still relevant. Usually when scientists sell this kind of research to grant departments, they try to provide a benefit to geriatric or otherwise medically impaired people, so that existing treatments may be improved. Studying muscle building itself just for the sake of it in gymbros is not a good strategy unless you want to spend your own money. And this stuff quickly gets very expensive if you want to do it right.
