The utility of high kicks (above chest level) has been debated. Proponents have viewed that some high front snap kicks are effective for striking the face or throat, particularly against charging opponents and flying kicks can be effective to scare off attackers. Martial arts systems that utilize high kicks also emphasize training of very efficient and technically perfected forms of kicks, include recovery techniques in the event of a miss or block and will employ a wide repertoire of kicks adapted to specific situations.
