Submission holds can be used in two groups: chokes and joint locks. A choke hold can stop the blood flow to the brain. If the opponent does not acknowledge submission in time, they can lose consciousness
Joint locks use the limb of the opponent and make a lever in the position they are in. This will make the joint to go beyond the normal measurement of movement. The increased pressure is controlled and let go if the opponent cannot get out of the hold. They end up submitting the match.
