Objective:
To assess the epidemiological profile of Jiu-Jitsu black belt athletes, including the prevalence of pain and shoulder function.
Methods:
Cross-sectional study carried out with Jiu-Jitsu athletes from 2014 to 2016. The studied variables were: sex, age, dominant limb, weight, height, profession, time of Jiu-Jitsu practice, weekly training hours, other practiced sports, comorbidities, injuries and previous surgeries, medications and habits. For the functional assessment of the shoulder, the ASES Score was used.
Results:
53 male athletes were evaluated. There was a prevalence of alcohol consumption (60.4%) and supplement use (32.1%). The practice of other sports included weight training (49.1%) and other martial arts (17%). There was a prevalence of knee (66.0%) and shoulder (52.8%) injuries and, in some cases, the need for surgical procedures. There was a prevalence of shoulder pain (73.6%) and more than half of the athletes (52.9%) had minimal or moderate limitation of shoulder function.
Conclusion:
Jiu-jitsu black belt athletes often have a history of injuries, with the shoulder being the second most affected body part. In more than half of the athletes, there was a prevalence of shoulder pain and functional limitation, according to the ASES Score. Level of evidence III, Retrospective comparative study.

01:09Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
