An arm bar is a grappling technique typically employed in martial arts, specifically Brazilian Jiu-Jitsu and Mixed Martial Arts, where the attacker secures control of their opponent's arm and applies leverage to force a submission or immobilize their opponent. In order to execute an arm bar, the attacker usually begins by positioning themselves on the ground, with their legs wrapped around their opponent's torso and one of their legs over the neck or head of their opponent.
The attacking fighter then extends their hips upward and clasps their hands together, locking their opponent's arm between their thighs and pressing it against their own upper body. By hyperextending the opponent's elbow joint, the attacker creates excruciating pressure and leverage that applies immense strain on the arm. This typically prompts the opponent to submit or risk significant injury.
The arm bar is a highly versatile technique that can be executed effectively from multiple positions, such as the top mount or guard positions. It is often considered one of the most fundamental submissions in grappling martial arts due to its versatility and effectiveness. Additionally, it can be performed with variations depending on the specific martial art and individual preferences.
Overall, the arm bar is a potent maneuver utilized to control and subdue an opponent by targeting the arm joint to inflict pain and establish dominance in combat sports.
The term "arm bar" is derived from the combination of two words: "arm" and "bar".
The word "arm" dates back to the Old English word "earm", which evolved from the Proto-Germanic word "armaz". This word has cognates in several Germanic languages, such as the Old High German "arm", Old Norse "armr", and Gothic "arms". It refers to the upper limb of the human body, extending from the shoulder to the hand.
The word "bar" originated from the Old English word "bearu", which meant "grove" or "wood". Over time, the meaning of the word expanded to include a variety of long, thin objects used as physical barriers or support.
The term "arm bar" emerged in the context of martial arts, specifically Brazilian Jiu-Jitsu.
