The term ‘martial arts” refers to a variety of sports that practice fighting techniques. There are millions of participants worldwide. Martial arts include styles from around the world, and some of these techniques have been practiced for centuries.
The most popular martial arts in the USA are karate (originating in Japan); taekwondo (from Korea); judo or jiujitsu (from Japan); kung fu (from China); Muay Thai (from Thailand); boxing (from ancient Greece?); and mixed martial arts (MMA), an American amalgam of many styles.
Injury types vary in martial arts depending on the style. In styles that involve kicking or striking with a fist or elbow (especially karate, taekwondo, kung fu, and Muay Thai), fractures, bruises, and abrasions are common. Some of these styles also teach breaking boards with the hand or foot as a training technique, and doing this improperly can result in fractures, bruises, and sprains.
