Boxing is the best-known organized sport in which the infliction of injury is the main goal, with the inducement of LOC via blows to the head a prime objective. An epidemiological study of sports injury (Toth 2008) found that boxing enormously exceeded all other sports, including U.S. football, in terms of mTBI incidence. The continued practice of activities encouraging such goals is of concern to the medical community, and organizations such as the American Medical Association (1999), Australian Medical Association (2007), and World Medical Association (2005) have issued positions advocating the elimination of boxing. Although there has not been a major controlled scientific study of boxing and long-term neurological sequelae, and the existing literature is mixed in terms of findings, there is sufficient evidence in this ongoing area of research to inform participants of the potential risks, at least from a conservative standpoint.
