“…In our study, four wrestlers sustained head trauma that required treatment at the emergency outpatient clinic in 817 matches, giving an injury rate per match of 0.5%. The frequency of head trauma per match is 5.1% (91 cases/1,770 matches) in Shotokan karate (U.K.), 6) 22.5% (96/427) in professional boxing (Australia), 24) and 5.7% (197/3,481) in professional kick boxing (Australia). 25) Compared with these values, the frequency of head trauma per match in our female wrestlers was low, but only 13 regular wrestlers had 817 matches in 14 months, so the number of matches fought per wrestler was clearly higher than in other martial arts.…”

“…Head trauma suffered during sports activities is well known, 1,2,6,7,13,14,16,21,[23][24][25] and incidents associated with snowboarding have increased recently with the rise in the popularity of the sport. 19) Professional wrestling in Japan has lead to the deaths of two female and one male wrestlers due to head trauma since 1997, 20) but these incidents have not been adequately evaluated.…”

The clinical characteristics of head trauma were evaluated in 18 wrestlers belonging to a female professional wrestling organization, 13 regular members and five trainees aged 15-34 years. Medical examinations for head trauma were performed in all wrestlers, and wrestlers treated at our emergency outpatient department were clinically evaluated. In addition, the relationships of head trauma with duration of the wrestling career of 1-16 years (mean 8 years) in the regular members, and less than 1 year in the five trainees, and body mass index (BMI) of 21.0-32.0 in the 16 subjects, excluding two trainees, was evaluated. Chronic symptoms were noted in four of the 18 wrestlers with long wrestling careers (16 years in 1, 13 years in 1, and 5 years in 2). Three wrestlers with symptoms immediately after head trauma showed recurrent retrograde amnesia and had low BMI (21.6, 21.6, and 23.1). Five wrestlers were treated at our emergency outpatient clinic, three required hospitalization and two showed intracranial traumatic changes on computed tomography (acute subdural hematoma in 1 and diffuse brain swelling in 1). Head trauma in female professional wrestlers is associated with longer wrestling career and low BMI. Periodic medical examinations are recommended to monitor for signs of head trauma.

“…18 Another study showed a threefold increased risk of injury and a higher risk of multiple injuries in taekwondo compared with karate. 13 Of 5 martial arts disciplines (Shotokan karate, Aikido, taekwondo, kung fu, and tai chi), taekwondo had the highest number of injuries requiring time off from training (59%). 14 Taekwondo has a high relative incidence of lower extremity injury compared with upper extremity injury because 80% of its competitive moves involve powerful, fast kicks.…”

The martial arts can provide children and adolescents with vigorous levels of physical exercise that can improve overall physical fitness. The various types of martial arts encompass noncontact basic forms and techniques that may have a lower relative risk of injury. Contact-based sparring with competitive training and bouts have a higher risk of injury. This clinical report describes important techniques and movement patterns in several types of martial arts and reviews frequently reported injuries encountered in each discipline, with focused discussions of higher risk activities. Some of these higher risk activities include blows to the head and choking or submission movements that may cause concussions or significant head injuries. The roles of rule changes, documented benefits of protective equipment, and changes in training recommendations in attempts to reduce injury are critically assessed. This information is intended to help pediatric health care providers counsel patients and families in encouraging safe participation in martial arts.

“…In other words, in Karate, one uses different technics of kicks (leg) and punches (hand) and defends without the using of any firearms. It is practiced in two fields of KATA (practice of a collection of techniques against no direct fighters), and KUMITE (fighting against real opponents) (Critchley & Meredith, 1999;Emmermacher et al, 2007;. Techniques like URA MAWASHI GERI, UKO GERI KEAGE, GER KEAGE, YOKO GERI KEKOMI, MAE GERI and MAWASHI GERI and etc., are performed by leg.…”

Sport Exerc., 9(Proc2), pp.S677-S686. Introduction: Karate is a martial art in which the technics are performed by kicks, punches (hand) and rotational movements. Ura MAWASHI GERI is a kind of kick which involves the core stability muscles of Lumbar -Pelvic areas, Quadriceps muscle (Lower extremity) and knee and lumbar -pelvic joints while being performed. The purpose of this research is to determine the muscle stimulation time pattern of Gluteus Medius (GM), External Oblique (EO) and Quadriceps muscles such as Vastus Medialis (VM), Vastus Lateralis (VL) at any phases of the implementation of the technique by the dominant leg. The muscular activities of VM, VL, EO and GM in 5 Iranian healthy elite Karatekas (in average age of (21/4) were recorded by the Electromyography device. The onset latency of the muscle activity and the Goniometric data (Knee Joint) were defined after processing the RMS of data and according to the Mean+4sd. After that, the average of the obtained records was used to determine the onset of each muscle separately at all phases of the implementation of the techniques. The results showed Glutesus Medius, at the phases of one, four, and five, and Vatus Medialis, at the phases of two and six, and the External Oblique at the third phase act earlier in comparison with other muscles.
