Last I checked (a few years ago), the pretty much universally accepted theory of muscle growth is that muscle fibres suffer micro-tears during exercise, and these heal back slightly stronger than before. Bodybuilders inflict more micro-tears on their muscle fibres than other exercisers and then try to maximise nutrition, rest, and hormones afterwards to maximise the healing.
The observations might be valid in some sense (e.g. not incorrect) but it looks to me like an insignificant finding that's been dressed up to get press attention. I mean, I don't think anyone was under the impression that all-nighters were somehow good for you, or even neutral. A good question would be how much damage they do, and more importantly, what nutrition or what should be done before or after an all-nighter to reduce the negative effects.
This researcher's next shocking discovery will be that crossing the road carries a risk of death.
