Along with the increasing popularity of taekwondo, there is a need of evidence-based talent identification (TID) and development programs based upon profiles of future elite athletes. This study first aims to investigate the differences between elite and non-elite taekwondo athletes in anthropometry, physical performance and motor coordination. The second aim is to demonstrate the applicability of z-scores in TID research. A total of 98 Taekwondo athletes between 12 and 17 years old were tested using a generic test battery consisting of four anthropometrical (Height, Weight, Fat Percentage, BMI), six physical performance (Sit & Reach, Sprint 5m, Sprint 30m, Counter Movement Jump, Squat Jump, Endurance Shuttle Run) and three motor coordination tests (Moving Sideways, Jumping Sideways, Walking Backwards). Based on the individual success at international competition level, 18 were categorised as elite athletes and 80 were considered as non-elite. T-tests (step 1) on raw test scores and MANOVAs on z-scores (step 2) were conducted to examine differences between the elite and non-elite taekwondo athletes for anthropometry, physical performance and motor coordination tests. Finally, z-scores were reconverted to raw scores to demonstrate practical significance for coaches. Overall, elite taekwondo athletes score better compared to the non-elite group. The MANOVA analysis better scores for elites on fat percentage (-0.55 versus 0.12;p = 0.006), BMI (-0.37 versus 0,08;p = 0.067) sprint speed 30m (-0.48 versus 0.11;p = 0.029), counter movement jump (0.79 versus -0.18;p = 0.000), squat jump (0.42 versus -0.11;p = 0.041), moving sideways (0.79 versus -0.18;p = 0.000) and walking backwards (0.54 versus -0.12;p = 0.006). This study confirms our knowledge on physical profiles of elite taekwondo athletes and expands our knowledge to the domain of motor coordination. This study showed how the z-score method can be used to distinguish between elite and non-elite athletes, the former being low in number by definition.

OBJECTIVE: To review the current evidence for the epidemiology of pediatric injuries in martial arts.
DATA SOURCES: The relevant literature was searched using SPORT DISCUS (keywords: martial arts injuries, judo injuries, karate injuries, and taekwondo injuries and ProQuest (keywords: martial arts, taekwondo, karate, and judo), as well as hand searches of the reference lists.
MAIN RESULTS: In general, the absolute number of injuries in girls is lower than in boys. However, when expressed relative to exposure, the injury rates of girls are higher. Injuries by body region reflect the specific techniques and rules of the martial art. The upper extremities tend to get injured more often in judo, the head and face in karate and the lower extremities in taekwondo. Activities engaged in at the time of injury included performing a kick or being thrown in judo, while punching in karate, and performing a roundhouse kick in taekwondo. Injury type tends to be martial art specific with sprains reported in judo and taekwondo and epistaxis in karate. Injury risk factors in martial arts include age, body weight and exposure.
CONCLUSIONS: Preventive measures should focus on education of coaches, referees, athletes, and tournament directors. Although descriptive research should continue, analytical studies are urgently needed.

Although considerable research indicates that mental energy is an important factor in many domains, including athletic performance (Cook and Davis, 2006), athletic mental energy (AME) has never been conceptualized and measured. Therefore, the aim of this study was to conceptualize and develop a reliable and valid instrument to assess AME. In Study 1, a focus group interview established the initial framework of AME. Study 2 used a survey to collect athletes' experiences of AME and develop a scale draft titled "Athletic Mental Energy Scale (AMES)." In Study 3, we examined the psychometric properties and the underlying structure of AMES via item analysis, internal consistency, and exploratory factor analysis (EFA). In Study 4, we used confirmatory factor analysis (CFA) to examine AMES's factorial validity; and examined concurrent and discriminant validity by examining correlations with athletes' life stress, positive state of mind, and burnout. In study 5, we examined the measurement invariance of the 6-factor, 18-item AMES with Taiwanese and Malaysian samples. Study 6 examined the predictive validity by comparing AMES scores of successful and unsuccessful martial artists. Across these phases, results showed a 6-factor, 18-item AMES had adequate content validity, factorial structure, nomological validity, discriminant validity, predictive validity, measurement invariance, and reliability. We suggest future studies may use AMES to examine its relationships with athletes' cognition, affect, and performance. The application of AMES in sport psychology was also discussed.

Vitamin D plays an important role in maintaining the physical health as well as the performance of athletes. This cross-sectional analytical study was conducted to determine vitamin D intake, sun exposure and skin types of both indoor and outdoor Malaysian athletes in the National Sports Institute, Bukit Jalil. Method: A total of 28 indoor (badminton, shooting, wushu and fencing) and 36 outdoor (athletics, football and hockey) athletes were recruited for this study. The dietary vitamin D intake was estimated using Vitamin D-specific Food Frequency Questionnaire (FFQ). The Sun Exposure Index (SEI) was calculated from Seven-day Sun Exposure Record while the skin types of athletes were determined using Fitzpatrick Skin Typing Questionnaire. Results: The mean age of the athletes was 21.02±4.11 years and their mean Body Mass Index (BMI) was 22.20±2.22 kg/m2. The mean body fat percentage of outdoor athletes was significantly lower than indoor athletes (p

To assess their awareness and usage of mouthguard and occurrence of sports-related oral injuries in athletes who involve in various sports activities in Kota Bharu. A cross-sectional study was carried out among 180 athletes aged 12 to 27 years. A structured interviewer-guided questionnaire was used to determine the prevalence of oral injuries sustained during sport activities, the use of mouthguard as well as the athletes' awareness of mouthguard use. The respondents consisted of 107 males (59.5%) and 73 females (40.5%) with a mean age of 16.7 years (SD 5.53). There were 60 (22.2%) athletes who had one or more types of sports-related oral injuries sustained. Laceration of lips, tongue and gums were the most frequent injuries (57.5%) while loosening of teeth and fracture of teeth sustained in 12.5% and 10.0% of athletes respectively. Malay traditional martial arts silat athletes, 17(68.0%) experienced the highest oral injuries among athletes. The prevalence of oral injuries was significantly different between ball sports, martial arts and other non-contact sports (p=0.002). Sixty-one athletes (33.9%) reported that they were aware of mouthguard; however none of the athletes used the mouthguards during their sports activities. Malay traditional martial arts silat was the most common susceptible to sustain oral injuries. None of the athletes were wearing mouthguard. Education on prevention of orofacial trauma should be given to the coaches and athletes. Wearing of mouthguard during sport activities should be compulsory during practice and competition events.

Participation in contact sports has been shown to carry a considerable risk of sustaining dental injuries. It is important for athletes to use available preventive gear to protect themselves from these injuries. Aim of the study: To assess the knowledge, habit and preferences of using mouthguards among university athletes. Materials and Method: Self-administered questionnaires, consisting of Part A - Age, gender, type of sporting activities, total hours dedicated to sports training, level of sports representation; Part B - Awareness of risk of dental injuries, knowledge on mouthguards such as definition of a mouthguard, role of mouthguard, use of mouthguards and reasons for not wearing mouthguards; and Part C — Experience of sustaining dental injuries during sports activities, were distributed. Athletes who were university students over 18 years and under 30 years of age and athletes who claimed to know about mouthguards were included in the study. Results: Data of a total of 225 respondents were analysed, consisting of 68% (n=154) male and 32% female (n=71) with the mean age of 21 years old. Only 46% (n=104) knew exactly about mouthguards and its role in the prevention of dental injuries during sports. Thirty seven percent of them (n=84) have used mouthguards and they were mostly in the martial arts group. The mouthguards were usually provided by the management team (62%). Forty percent of the respondents (n=91) claimed to have sustained dental injuries while playing sports and the injuries occurred more frequently in hockey (65.3%), basketball (60%) and soccer (45.2%). Conclusions: The incidence of dental trauma in contact sports shows that the awareness and use of mouthguards must be intensified. Awareness campaigns focusing on dental trauma should be organized to improve the knowledge of athletes.

Sports courage is one of the most important attributes to help competitive athletes overcome anxiety, nervousness, and other psychological obstacles, but this field of study is still being overlooked by most athletes and coaches. The purpose of this study is to validate the Malay language version of the Sports Courage Scale (SCS-M) for Silat athletes using confirmatory factor analysis (CFA). Data were collected during 9th UPSI International Pencak Silat Championship in Malaysia. A total of 258 competitors (male = 66.7%, female = 33.3%), with a mean age of 18 years (SD = 2.6), volunteered to participate in this study. The original SCS with 50 items underwent forward and backward translations into the Malay language and was pre-tested with ten martial arts athletes. Then, Silat athletes were asked to complete the translated SCS-M questionnaire. There were five factors in the SCS-M (i.e., mastery, determination, assertiveness, venturesome, and self-sacrificial behaviour). The first hypothesised model with 50 items did not result in a good fit to the data (RMSEA = 0.06, CFI = 0.93, NFI = 0.87, NNFI = 0.93, RMR = 0.14, SRMR = 0.09). A total of 17 problematic items were identified and were removed iteratively. The final measurement model with 33 items fit the data well (RMSEA = 0.06, CFI = 0.94, NFI = 0.89, NNFI = 0.94, RMR = 0.05, SRMR = 0.07). The reliability of each subscale based on Cronbach's alpha ranged from 0.64 to 0.76. The convergent and discriminant validities were achieved for the final measurement model. The revised version of SCS-M with 33 items was considered valid and reliable for measuring the sports courage in Silat athletes in Malaysia.
