Many people in these days participate in running as leisure due to urbanization and socio-economic development. Running is a simple exercise but it can induce its own specific injury pattern because of its repetitive motion. Most runners' injury is caused by chronic overuse syndrome rather than acute trauma. And common accompanying injury in running are anterior knee pain syndrome, Iliotibial band syndrome, stress fracture, plantar fasciitis, Achilles tendinitis, posterior tibial tendon syndrome. Most common area of runners' injury is knee joint. Therefore the authors reviewed the recent literatures and described the classification, etiology, prevention, rehabilitation in this article.

Objective: The purpose of this study was to examine the effect of increase in barbell weight on closely related variable to the anterior cruciate ligament (ACL) injury which are knee joint kinematics, joint load, joint moment, and maximum load attainment point during snatch of the weight lifting. Method: The subjects of the study were 10 male Korean national weight lifting athletes (69 kg 5, 77 kg 5; age: $21.80{\pm}3.91yrs.$, height: $168.00{\pm}4.06cm$, weight: $75.00{\pm}4.02kg$, career: $7.8{\pm}3.99yrs.$, snatch records: $168{\pm}4.06kg$). The weight of the barbell during the snatch operation was set at 70%, 75% and 80% of the highest records for each subject studied. Results: The result obtained from the one-way repeated measure ANOVA are as follows: With increased barbell weight, the extension moment of the left knee joint was higher in the 80% condition than the 70% (p<.001). However, other variables were not statistically significant difference. According to the factor analysis of the variables related to maximum load attainment point of the ACL major injury variables, the first sub-factor was the internal shear force, the posterior shear force, the abduction moment, and the muscle activity of the VL. The second sub-factor was the extension moment of the knee joint, compressive force, adduction moment, and the third sub-factor was the muscle activity of BF. Conclusion: These results indicate that the possibility of ACL injury can be lowered when performing a stable snatch movement.

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.

Objectives: The occupational accident rate was officially reported to be 0.77 per 100 workers in 2001 and 0.70 in 2009. The stagnant decrease in accident rate raises a question about the effectiveness of prevention activity because there have been active prevention efforts in the past 10 years. It is also necessary to know the exact status of occupational injuries to direct a prevention strategy. Methods: The author re-analyzed occupational injury statistics to find the reason for stagnant decreases in occupational injuries. Compensated occupational injuries cases were used to calculate fatal and non-fatal injury rates. Injuries from commuting accidents and sports activities were excluded as well as occupational diseases. The number of workers was adjusted to that of full time equivalent employees. Results: The fatal injury rate excluding injuries associated with commuting accidents, sports activities, and occupational diseases decreased from 12.59 in 2001 to 8.20 in 2009. In 2007, 67.5% of accidents that involved being caught in objects, which are mostly caused by machines and equipment, occurred in the manufacturing industry; this type of incident has decreased since 2001. The fatal and non-fatal injury rates in the manufacturing industry have continuously decreased while the rates in the service industry have not changed from 2001 to 2009. Non-fatal injuries might not be reported in many cases. The number of insured workers was underestimated as long working hours were not adjusted for in the reporting system. Conclusion: The occupational fatal injury rate has decreased and the non-fatal injury rate might have decreased during the last 10 years, although the statistics show stagnancy. The decrease of the injury rate was countervailed by various factors. Hence, the current accident rate does not reflect the actual situation of accidents in Korea. Korea needs to develop an improved system to more accurately calculate occupational fatal and non-fatal injury rates.

Purpose: To perform the retrospective analysis of the sports injuries sustained by the college Taekwondo athletes in the respect of the injury patterns, mechanism of injury and clinical outcome Materials and Methods: This study is based on 47 out of 49 college Takwondo athletes, who had experienced the Takwondo related musculoskeletal injuries severe enough to visit the clinic for medical treatment. The mean age at the time of injury was 18.8 years and 39 were males and 8 females. The Taekwondo career was average 9.6 years and the injuries were sustained at average 6.7 years of their career. The injuries were analyzed by the detailed interview with thorough physical examination. Results: Forty-seven Taekwondo athletes in the study experienced average 1.8 injury/person (total 85 cases) with 26 persons of one time experience(55.3%), 11 persons of 2 times(23.4%),4 persons of 3 times (8.5%),5 persons of 4 times (10.6%) and 1 person of 5 times (2.2%). Injuries occurred during training in 50 cases (58.8%), while during match in 35 cases (41.2%). Injuries occurred during the attack phase of the match are 26 cases (31.7%) while 49 cases (57.6%) during the defense phase. As for the pattern of injury, fracture was the most common with 49 cases (57.6%), followed by ligament injury with 21 cases (24.7%). The upper extremity injuries were 32 cases (37.7%) while the lower extremity injuries were 44 cases (51.8%) Mode of medical treatment were operation in 15cases(17.7%), cast in 21 cases(24.7%), splint in 33 cases (38.8%), physical therapy in 15cases(17.7%) and acupuncture in 1 case(1.1%) Conclusion: Almost all the college Taekwondo athletes (96%) experienced sports injuries severe enough to receive medical treatments with the fracture being the most common injury pattern. The injuries occurred more commonly during the defense phase of the competition.

The purpose of this study was to investigate leisure constraints based on the types of leisure sports activity(individual, partner, and group activities) in order to lead people to participate in and to continue their leisure sports activities. Data were collected from leisure sports participants in Seoul and Kyungki province. A total of 286 respondents were selected using the convenience sampling method. Leisure constraint's sub-dimensions for the respondents were named as facility and environment, negative perception, lack of condition, risk of injury, and lack of time. As the results of this study, first, respondents felt facility and environmental constraint the most and negative perception constraint the lowest. Second, there were differences in negative perception and lack of condition constraints based on the magnitude of participation. Finally, there were differences in facility and environment, negative perception, lack of condition, and risk of injury constraints based on the types of leisure sports activity.

Purpose: Bicycle riding is an increasingly popular sports and leisure activity in Korea. The aim of this study was to identify injury patterns of admitted patients who were injured from bicycle riding. Materials and Methods: This study examined 71 patients from Jan. 2008 to May 2009. There were 54 male and 17 female patients. We investigated the injured body parts, mechanisms of injury, location of injury, types of bicycles, purpose of bicycle riding, any concomitant luggage or passenger on rear seat, injury seasons and the helmet use. We analyzed the data using Injury Severity Score(ISS). Results: There were 11 cases of ISS 1, 41 cases of ISS 4, 2 cases of ISS 5, 13 cases of ISS 9, one case of ISS 13, two cases of ISS 16 and one case of ISS 29 among the 71 patients. 36 patients(50.7%) underwent surgery for upper and lower extremity injuries, two patients for vertebral body fractures, 8 patients for facial bone injuries and one patient for abdominal organ injury. There were 10 head injuries among whom three patients received treatment in ICU(4.2%). Conclusion: Bicycle riding can cause severe injuries with subsequent admission and major surgeries. Several measures including constructing more bicycle road, public campaign and wearing protective gears should be instituted.

There is always a risk of injury in sports. With the recent development of the economy, there have been more opportunities to be exposed to risks, and safety issues to prevent accidents have emerged as a central task. However, intensive research on trauma is lacking in the oral & maxillofacial area associated with sports. It has only been partially introduced, with a comprehensive survey of whole-body trauma or mixed with various trauma in the oral & maxillofacial area. In this paper, the overall content of trauma in the oral & maxillofacial area caused by sports activities will be reviewed for clinicians.

Running people is exceedingly increasing with the concern about the health. The health is defined as 'a state of complete physical, mental and social well being and not merely the absence of disease or infirmity' by WHO. It is very important to know that which level is one's physical strength and what is adequate quality and quantity of one's exercise. In this paper I would describe about exercise pre-scription, sports walking, and jogging. And sports injuries related running will be described briefly.
