American Academy Of Pediatrics 2016 Study reports a “..Karate has a lower and and usually less severe injury rate than in any other martial art forms..”

According to …Youth Participation and Injury Risk in Martial Arts, RA Demorset…

Martial arts that involve sparring  can be safer with rigrorous enforcement of rules prohibiting excessive force, dangerous movements, or blows to forbidden areas are prohibited and discouraged.  When  safety education is promoted and taught to  all athletes and instructors injuries are decreased.   All Pacific Renbukai Instructors are educated through USA Karate and Safesport with current rules guidelines strickly enforced with certification and accreditation.

In a study of karate participants younder than 18 years, a reported injury risk over a 12 month time period of 5.6 per 100 athletes was identified.   Karate focuses on techniques that just fall short on contact has been shown to have a lower injury rate compared to other martial arts…

There is a great danger in MMA injury as the  adult risk of injury is well documented in Adult matches. Overall risk of injury has been reported as 85.1 to 228.7 per 1000 athletic exposures- which is higher than other contact sports IE, college football with is 8.1 per 1000 athletic exposures.   Head and neck injuries accounted for 67%-78% of total injuries in MMA.
