Regarding your explanation of the concept behind rigor mortis. What about if we hold a limb in an awkward position for too long and it gets stiff--is the concept behind that the same idea?

Please understand that what we call rigor mortis only occurs at death, but at the molecular level, it can be traced to a lack of oxygen leading to a shutdown of the ETC, resulting in no ATP being available to muscle fibers. Sometimes, when a muscle stiffens because you've been holding it awkwardly, it's because blood flow has been reduced to that region, which of course means not enough oxygen and so on.
