Death when committed comes from what? More often from a fracture of the spine in the cervical spine and / or compression of the airway with a loop. In theory, trained neck muscles can do the trick if someone tries to strangle you with a stranglehold, for example. This will buy you time. But when hanging, it seems unlikely to me personally, because they try to do it with a big jerk, plus the weight of the body plays a decisive role. If you are lucky, and the hanging was carried out without a pronounced jerk, then muscle tension can also give a few minutes, but no more, there is already compression of the vessels of the head and asphyxiation due to compression of the larynx (when the muscles are tired) will lead to loss of consciousness and cessation of breathing and death , if someone doesn't run to help)
Well, I think about the fracture / dislocation of the cervical vertebrae and so it is clear)
Of course, anything is possible. But most likely not. Depends on exposure time. I do not think that a person will be able to keep the neck muscles in tension for as long as possible.
At the moment of hanging, the vessels of the neck are clamped first of all, the blood supply to the brain is sharply disrupted, which leads to its edema, and as a result of loss of consciousness ... A person loses consciousness in 3-4 seconds from the beginning of exposure. And unconsciousness is unlikely to be able to change anything in the situation.
