Fully depends on what medium they're in and if a part of you is stuck. Generally it wouldn't be ripped apart though, you would be squished when the plunger pushed down.

Let's say the scenario is this:

  1. When fully pushed down, there is still room for a human to stand/sit so no way the person would get squashed.

  2. No part is stuck and this is a normal environment/medium (a lab in a building so to speak)

  3. What happens to the human body when it's pressed down and when it is pulled up? I know it has to do with negative/positive pressure but unsure what would realistically happen

Your description sounds like the only effect would be first higher then lower than normal pressure. Read on what happens to divers who go down or up too much too fast. It would be the same I guess.

The dive issue wouldn't really play in here though because nitrogen dissolves in the blood over time due to breathing pressurized air. If the pressure was enough of a difference you could be crushed, but just as importantly when the pressure disappears your lungs could explode I suppose if you didn't breathe out.
