Abstract
AIM: This study was designed to assess the prevalence, distribution, and patterns of injury among athletes engaged in combat sports and compare the prevalence, pattern, and types of oral and maxillofacial trauma in these athletes.
MATERIALS AND METHODS: A total of 120 male athletes engaged in four combat sports (boxing, taekwondo, kickboxing, and Muay Thai) who had sustained bodily trauma were studied; 95 subjects with at least one traumatic injury to the face requiring treatment were referred to us by the physician team. The type of injury (facial laceration, facial fractures, jaw dislocation, etc.), site of facial injury (jaw, nose, malar bone, teeth, etc.), dental injuries (tooth fracture, displacement, luxation, and avulsion), causative sport (boxing, taekwondo, kickboxing, and Muay Thai) as well as demographic data were recorded. Injuries were examined clinically and radiographically, and treated accordingly by a specialist. Treatment data and demographics were recorded for each subject. Recorded data were assessed, and χ(2), ANOVA, and Kruskal-Wallis tests were used to statistically analyze and compare the data.
RESULTS: Of 120 subjects, 95 male subjects (79.2%), aged 18-25 years (avg. 20 years), had at least one traumatic injury to the face requiring medical treatment. These injuries included facial laceration, bone fractures (nose, mandible, and zygoma), dental injuries (displacement, luxation, fracture, and avulsion), and mandibular dislocation which were recorded in 83 (69.2%), 55 (45.1%), 53 (44.2%), and 8 (6.7%) cases respectively. Statistically significant differences were encountered among various injuries and the sports; kickboxing caused the most maxillofacial injuries and was identified as more injurious. Tooth fractures (59.7%) were the most common dental injuries, and the nose (84.7%) was the most frequently fractured facial bone. Lacerations were more common in Thai-boxers (93.3%). Injuries were significantly greater in professional rather than amateur athletes.
CONCLUSION: In this study, prevalence of facial injuries from combat sports professionals was significantly high (roughly 80%), especially in kickboxing (in part due to use of less protective gear). Because the nose and teeth sustained the most injuries, they require more attention with regard to prevention. Kickboxing was the most injurious of these combat sports and caused the most significant number of maxillofacial trauma. More safety apparel and protective guards seem warranted in athletes of combat sports if facial injury is to be prevented.

Relationship between Asian martial arts and health-related quality of life in Germany

Journal of Public Health

Aim
Due to the steady increase in health care costs, a greater focus on maintaining wellness and preventing health issues has been established. Historically, Asian martial arts were closely associated with maintaining healthfulness. Thus, the aim of this investigation was to determine if people who practice Asian martial arts gain any health-related quality of life benefits compared to the general population.
Subject and methods
Therefore, 343 martial artists practicing 8 varieties of martial arts answered the German standardized questionnaire 36 in a controlled setting at 24 martial arts schools (3 schools per martial art) between February 2008 and July 2008. These participants were not given information regarding the purpose of the study. Additionally, between July 2008 and December 2008, 2,512 martial artists completed an online version of the German standardized questionnaire 36.
Results
The results of those completing the questionnaire in person differed from those responding to the online questionnaire. Compared to the general public, both martial arts groups rated their health-related quality of life to be better. Of the parameters evaluated, the greater differences were observed for physical aspects of health than for psychological aspects.
Conclusion
Thus, these results indicate that participation in martial arts provides health-related quality of life benefits associated with the prevention of health problems. However, further studies are needed to understand the complex relationship between the practice of martial arts and improved health.

Changes in peak leg power induced by successive judo bouts and their relationship to lactate production.

Abstract
Eleven male judoka, who compete at national level, were recruited with the aim of investigating changes in peak leg power as a result of successive judo bouts and their relationship with lactate production. The participants executed a force-velocity curve to determine peak power in a 90° squat exercise in concentric work. The group then participated in four 5-min judo bouts each separated by 15 min of passive rest. The power developed as a result of the load associated with the maximum peak power reached in the preliminary test was determined, for the same movement, before and after each bout. Finger capillary blood samples were taken after each bout to determine the maximum lactate concentration achieved and lactate clearance. The results showed no effect of successive bouts on peak leg power (P > 0.05) and no difference when comparing the power measured before and after each bout (P > 0.05). Maximum lactate concentration of the fourth bout was lower than that of the first (12.6 ± 3.5 and 14.6 ± 4 mmol · l(-1) respectively; P < 0.05), although there was no difference in their clearance dynamics (P > 0.05). On the basis of the results obtained, we conclude that successive judo bouts, with the structure proposed in this study, produce high acidosis levels, which have no effect on the peak power developed in the legs.

Mudanças nas regras da WKF aumentam número de projeções nas competições de karatê
