I was looking over some old DBZ episodes and i noticed that when Gohan is fighting the little cell people as SSJ2, he released a big burst of energy that causes the little cell people to fly back. I reckon this should be in ESF you charge up a lot of energy (same as you would a beam) and when you release it, it lets out a huge burst which causes people of a smalller PL to fly back and maybe cause people of a bigger pl just to move back a bit.
