|Ukemi means "body control" while falling. Due to the repeated exercise of falling techniques, you learn to control your entire body. Ukemi "passive activity" is. The result is the goal of judo, namely the willingness to throw and to be thrown. A good level of ukemi is not only for the safety of the judoka very important, it also promotes the development on the way (Do).|
The basic idea of ukemi is: The force of the impact of UKE must be spreaded on the largest possible area of the tatami, and so relieve the impact. While falling is soughted to "land" on a large area and to protect the pain sensitive "rough edges" (knees, elbows, shoulders, wrists, etc.) of the body. By appropriately chopping, the impact energy is scattered much wider and partially transferred to the ground. A perfectly controlled ukemi allows UKE to drop from a certain height, high falling speed and massive impact energy without injury.
Physical studies have shown that at well executed throwing techniques (Nage waza) from the stand, the forces can be up to 12 times body weight of UKE. These force peaks can be achieved in just 0.2 seconds. Is the partner/opponent accelerated by judo techniques and be thrown, the kinetic energy can be either soft on a long way or hard on a short way stopped, whereas it has two basic forms of ukemi developed:
There are a variety of falling techniques, but all ultimately based on the base falling exercises:
