TL;DR: I need more information on the mechanical properties of human skeletal muscle; if you have such information, please give it to me.

I'm writing something on how much more effective (or otherwise) spider silk would be as a muscle and/or connective tissue in prosthetics in in comparison to human skeletal muscle and connective tissues. As such, I need information on several of the mechanical properties of human skeletal muscle, such as its:

I was also able to find another source on its Young's modulus, but it doesn't specify the direction the Young's modulus was measured in.

One of the few sources I currently cannot find problems with are this one, on how much a strand of muscle can elongate before it fails - and that's because I can't find any other sources which could contradict it - and this one, on how much force a longitudinal muscle of a certain cross-sectional area can contract with: ~30 newtons per square centimetre, or 300 kPa.

There's also the content of and source of this Biology Stack Exchange answer by WYSIWYG, especially the image displayed:

...although I'm still trying to figure out which parts of it correspond to which points on a stress-strain curve.

The unifying factor here, however, is that I don't have enough sources - so few, in fact, that I have no reliable information on the fatigue limit. Please give me more.

Muscle by itself is very weak, all the strength is in the fascia (the tissue around the muscle).

You can see a review here, the muscle itself is negligible strength while the fascia is in the megapascal range.
