Why is Korea so strong in short track speed skating?

Crossing a curve is a very important technique in short track speed skating. The traditional thought is that the more the lane is, the more favorable it is because the skating distance is short, but the speed should be slowed down when crossing the curve. The Korean team's advanced technique is that when they are going through a corner, they achieve an effect of not slowing down, and even accelerating, by shifting the body's center of gravity, and shifting their step point - so they actually accelerated from the outside lane to overtake the leader on the last lap, or even the last corner, in several races. It's a whole range of techniques, including the ability to use little force on the straights to great effect. This makes the Korean team more powerful than the rest of the field the further back they go in the longer races.
