Blood is pushed through your arteries by your heart. But because blood vessels are flexible that pressure dissipates over long distances. So your heart isn’t pushing the blood as much in your veins. To help the venous blood get back to the heart they have one way valves that force the blood in the right direction when your muscles squeeze the veins during physical activity.
Compression limits the flexibility (expansion) of veins and increases how much they are squeezed to take advantage of the valves that force blood to move in the right direction.
