I agree with the guy above you; the results of their hypothesis were already very well known. Everyone realizes that getting less exercise decreases calories burned in a day. These studies need to start going further in depth than just reading that your health gets worse if you stop exercising.
I think you and the guy above are missing a key point in this paper, the emphasis on "Short Term" in the title.
While most people realize that a sedentary lifestyle has issues, it will surprise a lot of people that a typically active person who is sedentary for 2w (e.g. an injury, a deadline at work, whatever) might have measurable metabolic changes...
It's kind of obvious, I got a weird pneumonia, and even when interspersing walking for and hour or more I'm starting to feel my back muscles getting sore just from lying in a bed and sitting for most of the day.
This has been just over two weeks. And the weather is now cold so I cannot take longer walks.
(On the other hand, diet is even more adjusted so I lost weight rapidly.)
I think every one knows what needs to change as well. To effectively use our bodies in the way they've evolved, we need to be using them from sun-up to sun-down every day.
We evolved on savanas, upland steppes, mountains, and jungles; hunting, gathering, foraging, defending, building, with raw human power, for the vast majority of our time on this planet.
If we had to push plows with human labor; gather and reap the harvest by had, I guarantee you we'd be fit af.

We'd also be worn out by middle age. Look at various manual labor trades for example. You wind up with a couple muscle groups in great shape and a couple others that are just destroyed.
I’d guess “Labor” is the key operative word here, i.e. working not directly for what is produced but selling labor for a low, unskilled wage. I wonder whether subsistence farming one’s own land is necessarily as bad, I’d think you can just stop working when you have enough to eat, but people paid by the hour or whatever always seem to push too far.
> we need to be using them from sun-up to sun-down every day.
That is not clear at all. Using them more, yes. Avoiding repetitive actions (or mitigating them) yes. I'd like to see any evidence that has been gathered for sun-up to sun-down being necessary; I'd assume overuse is also a problem.
