Injuries Common to the Brazilian Jiu-Jitsu Practitioner.

Abstract

Brazilian jiu-jitsu (BJJ) is a martial art that focuses on ground combat, emphasizing skill over strength and submission over striking. The purpose of this study is to evaluate the nature of injuries affecting practitioners of BJJ in the settings of competition, training, and conditioning. An online survey was created to collect demographic and injury-specific information. This survey was distributed to the 234 schools in the United States registered with the International Brazilian Jiu-Jitsu Federation (IBJJF). The survey was also distributed to local BJJ schools and at local tournaments in the Greater New York City area. Data from atotal of N=56 participants were recorded for this survey. The majority of participants were male (n=44, 78.6%) and amateur competitors (n=29, 51.8%) with an average duration of BJJ training of 6.9 ± 5.9 years. The majority of participants (82.1%) train at least six hours per week and compete in an average of 4.6 ± 2.5 competitions per year. The most common injuries were to the finger/hand (78.6%) and knee (61.5%). The most commonly reported fracture was of the hand/fingers (n=6). Of the 156 total injuries reported, 133 (85.3%) occurred during practice or training rather than in competition and 76 (48.7%) required medical attention. Few injuries required surgical intervention. This study provides novel information regarding injury characteristics of BJJ practitioners with respect to the level of training and use of protective equipment that can guide expectations and management for this unique group of athletes. Amateur BJJ practitioners are the most commonly injured, and largely experience injuries of the upper extremities during training or conditioning rather than during competition.
