A chokehold is a technique used in martial arts and self-defense that restricts airflow by applying pressure to the neck. This can be done by using the arms or legs to compress the throat or windpipe, making it difficult for the person to breathe. Chokeholds are often used in mixed martial arts and law enforcement situations, but they can be dangerous if applied improperly. There are different types of chokeholds, including the rear-naked choke and the guillotine choke. While some chokeholds can lead to unconsciousness if held for too long, they are generally intended to subdue an opponent without causing permanent harm. Proper training and understanding of these techniques are essential for safety.
