“…In the present study, there was a high prevalence of MSK-I (76%) among Brazilian rugby, soccer, combat, handball and water polo athletes, and 19% reported a history of tendinopathy and joint and muscle injuries in combination. Our result is in agreement with that of Graças and colleagues, who observed a prevalence of 82.6% of MSK-I in Brazilian jiu-jitsu athletes [16]. In addition, 65% of first division soccer athletes showed some MSK-I type during the season [17], and 58% of university athletes from fifteen different sports had at least one injury at the end of the sports season [18].…”

“…Age-adjusted logistic regression analyses have shown that athletes who train more than 2 h per day are 2 to 3.5 times more likely to develop an MSK-I, mainly in sports involving overuse or repetitive movements [32]. In addition, this result is in consonance with a Brazilian study, which observed a higher occurrence of MSK-I in jiu-jitsu athletes aged 30 years or more [16], and with the study of Snodgrass and colleagues, in which age was associated with muscle-tendon injury history in the neck in Australian rugby union players [33]. This can support further analytical studies by creating surveillance programmes to increase the career duration of athletes.…”

Background: Musculoskeletal injuries (MSK-I) are a serious problem in sports medicine. Modifiable and nonmodifiable factors are associated with susceptibility to these injuries. Thus, the aim of this study was to describe the prevalence of and identify the factors associated with MSK-I, including tendinopathy and joint and muscle injuries, in athletes. Methods: In this cross-sectional observational study, 627 athletes from rugby (n = 225), soccer (n = 172), combat sports (n = 86), handball (n = 82) and water polo (n = 62) were recruited at different sports training centres and competitions. Athlete profiles and the prevalence of MSK-I were assessed using a self-reported questionnaire. Only previous MSK-I with imaging confirmation and/or a positive physical exam by a specialized orthopaedist were considered. The association of the epidemiological, clinical and sports profiles of athletes with MSK-I was evaluated by a logistic regression model. Results: The mean age was 25 ± 6 years, and 60% of the athletes were male. The epidemiological, clinical and sports profiles of the athletes were different for the five sport groups. The MSK-I prevalence among all athletes was 76%, with 55% of MSK-I occurring in a joint, 48% occurring in a muscle and 30% being tendinopathy, and 19% of athletes had three investigated injuries. The MSK-I prevalence and injury locations were significantly different among sport groups. There was a predominance of joint injury in combat sports athletes (77%), muscle injury in handball athletes (67%) and tendinopathy in water polo athletes (52%). Age (≥30 years) was positively associated with joint (OR = 5.2 and 95% CI = 2.6-10.7) and muscle (OR = 4.9 and 95% CI = 2.4-10.1) injuries and tendinopathy (OR = 4.1 and 95% CI = 1.9-9.3). Conclusion: There is a high prevalence of tendinopathy and joint and muscle injuries among rugby, soccer, combat sports, handball and water polo athletes. The analysis of associated factors (epidemiological, clinical and sports profiles) and the presence of MSK-I in athletes suggests an approximately 4-5-fold increased risk for athletes ≥30 years of age. The identification of modifiable and non-modifiable factors can contribute to implementing surveillance programmes for MSK-I prevention.

“…The development of the sports discipline of Brazilian jiu-jitsu (BJJ) and its increasing popularity was followed by an increasing number of publications on the physical and physiological pro le of BJJ athletes [1], on the biomechanics aspects of the athletes [2], on the technical and tactical analyses [3,4], and on the incidence of injuries [5][6][7][8]. Brazilian jiu-jitsu (BJJ) is a type of martial art and as such it requires certain physical and physiological qualities, such as mesomorphic somatotype, aerobic and anaerobic power, muscle power and endurance and exibility [1,2].…”

Background The aim of the study was to assess the prevalence of back pain in non-professional Brazilian jiu-jitsu (BJJ) athletes, and to assess the relationship between their back pain and postural disorders. Methods The study involved 61 subjects: 31 subjects who trained Brazilian jiu-jitsu and 30 subjects who had never trained any martial arts. The mean BJJ training time in the study population was 3.89 ± 4.13 years. The athletes’ trained 4.06 ± 2.8 times a week and took 1.5 hours. Postural assessments were conducted with the use of the photogrammetric method. The assessment of back pain and injuries was conducted with the Oswestry Disability Index (ODI) and with our proprietary questionnaire. Results Among both populations, 37 subjects reported back pain − 22 athletes (71.0%) and 15 controls (50%) (p = 0,094). There were no differences in back pain location between the two groups (p > 0.05) or in functional state on the Oswestry Index (21.5% in the study population and 20% in the control group, p = 0.121). We observed significant differences between the groups in the values of four of the postural parameters. For each of these four parameters, parameter values were higher in the study population: DCK-spinal height from C1 to S1 (474.8 ± 25.4 vs 447.1 ± 25.9, p = 0.001); RKP-length of kyphosis between C7 and thoracolumbar junction (321.9 ± 15.2 vs 307.3 ± 22.2, p = 0.010); RLL-length of lordosis between S1 and thoracolumbar junction (152.9 ± 18.2 vs. 139.8 ± 17.6, p = 0.009) and KNM-pelvis inclination angle (2.24 ± 1.18 vs. 1.64 ± 1.34, p = 0.041). We found statistically significant differences in the study population between the athletes with and without back pain. These differences were found in the following parameters: RKP-length from C7 to peak of kyphosis (p = 0.01) and TT-difference between height of the waist triangles (p = 0.018). Conclusions There are no differences in back pain in regard to its frequency, intensity and location between non-professional BJJ athletes and subjects who do not train BJJ. Both in the study population and in the control group the spinal pain was minimal or moderate on the Oswestry Disability Index. BJJ athletes who reported back pain had characteristic postural changes in some of the analysed postural parameters in comparison to BJJ athletes who did not report back pain.

“…With a significant population of BJJ participants older than 30, there is an opportunity to analyze concussions in a population that are studied less frequently [ 4 ]. It has been shown that musculoskeletal injuries in BJJ occur more frequently in practitioners over age 30, although there has been no research published on brain injuries in this age group [ 13 ]. Outside of BJJ, there is evidence that females are more likely to suffer concussions in a given sport than their male counterparts [ 12 ].…”

Brazilian Jiu-Jitsu (BJJ) is a rapidly growing grappling sport with a wide spectrum of participants. This cross-sectional study examined the lifetime prevalence of concussion in adult BJJ practitioners in the United States using a 17-item survey. A total of 778 (11.4% female) BJJ practitioners with a median age of 31 years completed the survey. Overall, the lifetime prevalence of the self-reported BJJ-related concussion was 25.2%. However, the prevalence was higher among females than males (43.0% versus 22.9%; X2(1,740) = 15.129; p < 0.001). Factors independently associated with significantly increased odds of having sustained a BJJ-related concussion included a prior history of concussion (OR 1.76, 95% CI 1.14–2.74; p = 0.011) and female gender (OR 1.95, 95% CI 1.04–3.65; p = 0.037). The median return to sports time was three days, with 30.3% of participants returning on the same day as being concussed. The present study represents the first epidemiological research examining the concussions in BJJ. The results underscore the need for increased education on concussions and return to sports guidelines among BJJ coaches and practitioners.
