I’m not sure the point of your question, and I suspect that you already know the answer.
If the load is constant through the ROM, it’s constant resistance. Add a lobed cable swivle and it becomes variable resistance. If load is placed with no joint movement it’s a “static” resistance, although I would never use that term. It’s, as has been pointed out, called isometric resistance.
I have no idea of what you mean by “accommodating resistance.”
What is it that you really want to know?
You would get more response if you asked what the difference is between the different types of resistance and their application.
anything with only a barbell or dumbbell is constant resistance.
if you add bands or chains to any of the above exercises you get variable resistance…..or if you use resistance bands only or the old universal gym systems, and I think the strive brand of exercise equipment has variable cams in their machines that can move the heavy point to the beginning, middle, or end.
Accommodating resistance is a form of variable resistance.
static resistance is any exercise with force that has no movement.
