What is the typical percentage range/limits of extension/contraction during normal ranges of motions for muscles? Assuming a rest length in a typical relaxed state.

I'm mostly interested in humans but I am also curious if it is typically the same range across other animals too?

  • $\begingroup$ can you be a little more clear - do you mean what percentage of muscle shortening occurs (i.e. with 100% defined as resting/non-stretched muscle)? $\endgroup$ – Vance L Albaugh Oct 21 '16 at 19:17
  • $\begingroup$ Yes so for example given a rest length at 100%, saying typically muscles extend to 110% and contract to 80%. Specifically it's to determine a sensible default starting range for a motion simulation I am working on. $\endgroup$ – iam Oct 22 '16 at 4:19
