This epidemiological study aims to determine the incidence, areas, severity, and time of occurrence of sports injuries in elite female rowing athletes who were training at the Jincheon National Training Center for a 1-year period from January 1st to December 31st, 2017. According to the daily injury reports form of the IOC, sport events, weight division, injured area, and cause of injury were recorded, and the following results were found. Upon comparing the incidence of sports injuries, there was a significant difference in weight of double scull athletes. In terms of sports, there was a significant difference between pair and athletes who played double skull. Injuries occurred most commonly in the lower extremity (40.5%), followed by the trunk (35.1%), upper extremity (24.3%). for all athletes in rowing. The knee and lumbar spine/lower back were the most common injury sites. More than 60% of all injuries were Level III, and injuries occurred most frequently during training, followed by weight training and then competition.

Objective: The purpose of this study was to investigate the injury factors of Taekwondo jumping kick during landing phase according to the experience of injury and to suggest a stable landing movement applicable to free style Poomsae. Method: The participants were non-injury group (NG), n = 5, age: 20.5±0.9 years; height: 171.6±3.6 cm; body weight: 65.7±4.4 kg; career: 5.0±2.7 years. Injury group (IG), n = 9, age: 21.0±0.8 years; height: 170.9±4.6 cm; body weight: 67.1±7.0 kg; career: 8.6±5.0 years. The variables are impact force, loading rate, vertical stiffness, lower limb joint angle, stability, balance, and muscle activity in the landing phase. Results: NG was statistically larger than IG in the gluteus medius (p<.05). The impact force, loading rate and vertical stiffness decreased as the landing foot angle, the ROM of lower limb joint angle and COM displacement increased (p<.05). Conclusion: Based on the results, it means that the landing foot angle plays an important role in the impact reduction during landing phase. It is required the training to adjust the landing foot angle.

Purpose: This study examined the injury and rehabilitation of athletes with disabilities in racket sports projects (i.e., badminton, table tennis, and wheelchair tennis). In addition, the characteristics of each project and the differences among those projects are discussed. Methods: Business team athletes with disabilities in racket sport were enrolled as subjects (i.e., 19 badminton athletes, 19 table tennis athletes, and 19 wheelchair tennis athletes). The real conditions of the injury, injury severity, injury site, symptoms, and rehabilitation methods after injury were analyzed. Results: No significant differences were observed among the actual condition, injury severity, symptoms and the methods of rehabilitation on racket sport for athletes (i.e., badminton, table tennis, and wheelchair tennis athletes) with disability. The differences were focused mainly on the injury sites due to the characteristics of the different projects, and specific technical actions. Conclusion: This study examined the real condition of the injury, injury severity, injury site, symptoms and rehabilitation methods after the injury on the rackets (i.e., badminton, table tennis, and wheelchair tennis) athletes with disabilities. The data can be used to eliminate the incidence of injury and minimize the injury severity for racket athletes with disabilities. In addition, it can also be used for the disabled, who like racket projects, as the fundamental material to prevent injury and assist in recovery.

The objective of this study was to identify EXE (1 hr a day at 21 m/min for 5 day/wk, at 0 % grade for 6 wk) on myocardium glucose metabolic phenotypic proteins (AMPK-PGC-1${\alpha}$-GLUT-4) and HSP-60 protein expression after ischemia/reperfusion injury (IRI) in STZ-induced rats. EXE was performed using STZ-induced diabetic rats on a rodent treadmill (28 m/min, 1 hr/day, 5 day/wk for 6 wk). The results of this study suggest that i) serum insulin level was not changed among groups (p>l0.05). ii) the LVDP level increased significantly in the STZ-EXE-IRI group compared to the STZ-IRI group at 60 min (p<0.01), 70 min (p<0.05) and 80 min (p<0.05) after reperfusion, respectively, and iii) AMPK phosphorylation (p<0.01), PGC-1${\alpha}$ protein (p<0.001), GLUT-4 protein (p<0.001) and HSP-60 protein expressions (p<0.05) increased significantly in the STZ-EXE-IRI group compared to the STZ-IRI group. In conclusion, the findings of the present study reveal that EXE may provide therapeutic value to insulin dependent diabetic patients with peripheral insulin resistance and myocardium injury by improving glucose metabolic proteins (AMPK-PGC-1${\alpha}$-GLUT-4) and heat shock protein-60 (HSP-60), along with increasing LVDP levels and decreasing glucose levels. Therefore, EXE protects the STZ-induced diabetic myocardium injury against ischemia/ reperfusion injury.

Objective: The purpose of this study was to understand the injury mechanism and to provide quantitative data to use in prevention or posture correction training by conducting kinematic and kinetic analyses of risk factors of lower extremity joint injury depending on the change of direction at different angles after a landing motion. Method: This study included 11 men in their twenties (age: $24.6{\pm}1.7years$, height: $176.6{\pm}4.4cm$, weight: $71.3{\pm}8.0kg$) who were right-leg dominant. By using seven infrared cameras (Oqus 300, Qualisys, Sweden), one force platform (AMTI, USA), and an accelerometer (Noraxon, USA), single-leg drop landing was performed at a height of 30 cm. The joint range of motion (ROM) of the lower extremity, peak joint moment, peak joint power, peak vertical ground reaction force (GRF), and peak vertical acceleration were measured. For statistical analysis, one-way repeated-measures analysis of variance was conducted at a significance level of ${\alpha}$ <.05. Results: Ankle and knee joint ROM in the sagittal plane significantly differed, respectively (F = 3.145, p = .024; F = 14.183, p = .000), depending on the change of direction. However, no significant differences were observed in the ROM of ankle and knee joint in the transverse plane. Significant differences in peak joint moment were also observed but no statistically significant differences were found in negative joint power between the conditions. Peak vertical GRF was high in landing (LAD) and after landing, left $45^{\circ}$ cutting (LLC), with a significant difference (F = 9.363, p = .000). The peak vertical acceleration was relatively high in LAD and LLC compared with other conditions, but the difference was not significant. Conclusion: We conclude that moving in the left direction may expose athletes to greater injury risk in terms of joint kinetics than moving in the right direction. However, further investigation of joint injury mechanisms in sports would be required to confirm these findings.

The purpose of this study was to investigate the frequency of sports injury among Korean junior elite golf players. The survey was made through the questionnaire which consist of eight categories and 280 valid answers were used to perform frequency analysis. The results indicated that 197 out of 280 participants experienced golf injuries (30%: during a game, 70%: during a practice) and 70% of them also experienced injuries within a year. The frequency analysis for the site of injury has shown that back was the most vulnerable area for all players(33%), followed by the right wrist, left shoulder and elbow for male players. Among female players, left wrist was the second weak site of injury, followed by the right wrist, right thoracic spine, and left shoulder. A few of them also have shown abnormal symptoms of ruptured lumbar disk, scoliosis, and lordosis and these injuries might be caused by the lack of flexibility and the fatigue due to over-practice. High frequency of wrist injury also demonstrated that excessive chopping or punching shot and poor environmental course conditions may cause this injury to be common. Overall, lack of warm up time, lack of strength and flexibility, and excessive amount of practice were the major reasons of injury for the junior elite golfers in Korea. The study also proved that these young Korean golfers actually had more chances to be faced with the injury than average. Thus, it is necessary to develop systematic and scientific methods of training, and prevention, treatment of these injuries with medical professionals.

스포츠 선수는 경기 중 발생할 수 있는 몸싸움과 격렬한 동작으로 인해 항상 구강악안면 외상에 노출되어 있음에도 불구하고 구강보호장치는 불편하고 불필요하다는 인식이 강한편이다. 그러나 구강보호장치는 외부 충격 시 치아를 보호하고, 응력을 분산시키는 역할 등 스포츠 선수에게 없어서는 안 될 중요 예방대책이다. 그렇기 때문에 스포츠 선수들의 불편하고 불필요하다는 인식을 개선시켜줄 필요가 있고, 스포츠 선수의 구강 보호차원에서 구강보호장치의 사용을 일반화 하는 것이 중요하다 할 수 있다. 본 연구는 스포츠 선수 290명을 대상으로 구강보호장치 사용 실태를 조사하여 착용 경험율 6.6%, 현재 착용률 3.8%, 사용할 필요성 25.9%, 사용할 의사 28.3%인 결과를 얻어 스포츠 선수들의 구강보호장치 사용률과 인식모두 매우 낮은 실정을 알 수 있었고, 성별, 연령, 신체 접촉 정도, 구강악안면 외상경험, 외상 대처법 교육경험에 따라 구강보호장치 사용률에 변화가 있는지 분석한 결과, 사용률이나 인식이 남성과 고연령층이 높다는 것을 알 수 있었고, 신체 접촉이 많은 종목과 구강악안면 외상경험, 구강악안면 외상대처법 교육경험이 있는 스포츠 선수가 구강보호장치 사용률과 인식이 조금 더 높은 것으로 나타났다. 따라서 아직까지 스포츠 선수에게 구강보호장치에 대한 인식과 사용은 매우 낮은 실정이지만 경험과 교육을 통해 충분히 개선될 수 있고 향후 스포츠 선수들의 구강보호를 위해 많은 교육이 필요할 것으로 사료된다.

Snowboarding has become one of the premier alpine sports. The past decade has seen the popularity of snowboarding increase dramatically and the recent Winter Olympic Game showcased the strong visual appeal of the sport and the youth-oriented lifestyle and culture that accompanies it. The injury profile of the sport has also undergone change along with technological advances in boot and binding systems and the changing demographics of the sports participants. Central to the development of injury-prevention strategies is knowledge of the profile of injuries that occur, understanding those who are at particular risk and, if possible, the biomechanical factors involved in each injury type. Snowboarding was initially considered a dangerous, uncontrolled, alpine sport - an opinion based on little or no scientific evidence. That evidence has rapidly grown over the past decade and we now know that snowboard injury rates are no different to those in skiing; however, the injury profile is different. The purpose of this review is to give some perspective to the current snowboard injury literature. It discusses not only the demographic profile of those injured and the type of injuries that occur, but also gives some insight into the progress that has occurred in determining the impact of specific prevention strategies, such as splints to prevent injuries to the wrist/forearm. As the literature indicates, however, some things will not change, e.g. injuries are more likely to occur in beginners and lessons need to be reinforced as a fundamental aspect of any injury-prevention strategy.
