So, what, am I supposed to get my butler to lift the weights up for me so that I can just lower them back down?

As the article says, feel free to use two hands to raise the weight, but only one to lower it.
Things are certainly changing thanks to cross fit becoming cool
Given all that, I find it interesting this study is partyl published from researchers based in Japan :) It's almost like it's their "opinion".
Earlier quoted context omitted.
Isn't the burden on that working body half 2x then?
It would be the same burden. You're still using the same dumbbell, you're just working one arm at a time instead of two.

The study authors aren't arguing that dumbbell curls should be the center of your workout. And they are are presumably using an isolation exercise because it is more straightforward to test improvements to strength when you are just examining the effect on a single muscle group.
> >It found those who only lowered a weight saw the same improvements as those who raised and lowered weights — despite only performing half the number of repetitions.
> No shit. That's because eccentric exercises are far more fatiguing for the muscles.
It is a giant pet peeve of mine when scientists run a diligent study and then the response is "No shit, that's common sense" with the audacity to call it "junk science." Putting actual data and numbers behind a "common sense" belief is what science is all about - it is not "junk science".
I think there are other fair critiques about the applicability of this study (for example, another commenter mentioned that they were dealing solely with untrained individuals), but the fact that they used dumbbell curls isn't one of them.

This article is a perfect example of 1. An academic publishes an extremely limited study, group size is 14 people that haven't exercised much, they do a single exercise, and they mention eccentric-only is particularly useful for rehabilitation. They make no outrageous claims whatsoever, they just put more numbers to something that is widely known and has been measured before. 2. Some popular news outlet wants to get…

It's one data point, one among many. It won't significantly change my beliefs about anything, unless other studies start confirming its findings.

> you probably shouldn't be doing isolation exercises unless you don't mind risking injury and joint inflammation in the long-term
I have never heard of anyone getting injured from dumbbell curls or lateral raises, but everyone I know has tweaked something from a momentary lapse of form in compound movements. Turns out moving 400lb+ pounds close to your limit regularly isn't that safe.
> No one serious uses a "leg press" - another injury-prone nightmare
I know both serious powerlifters and "serious" (non competitive) bodybuilders that use leg press as an accessory on leg days. Stability provided by machines just let you lift more weight.
