Sorry I didn't see this.
Pretty sure we are on the same page, like you said little differences in the terminology, but I wasn't really consistent. When I said overstretched above I meant chronically lengthened, and thus the muscle, over time, becomes strained. This oopposed to a traumatic overstretching resulting in a strain.
I agree that typically METS is better than rolling, as anything with the hands is going to be much more focal and efficient.
I will say though that I see people desiring to have massage type work done on lengthened muscles due to the muscles giving the client a perceived tightness. This is when actually the muscle is chronically lengthened. That is, you typically don't notice a muscle is tight until it is stretched.
I've seen other people talk about a muscle being weak due to scarring and adhesions but can't say I've really seen this myself. Of course that doesn't mean it's not happening though. Any examples of this you could share?
