Purpose: The purpose of this study is to evaluate diagnosis and treatment of acetabular labral tears in sports injuries. Materials and Methods: From March 1995 to January 2000, We treated 15 patients with acetabular labral tear by sports injuries. There were 6 men and 9 women. Mean age was 41 years old. Running injuries are 5 cases, fighting 3, aerobic exercise 3, swimming 2, climbing 1, bicycle 1. For conservative treatment, we performed medication and observation at least for 1 year. For the patients with arthroscopic surgery, we performed Harris Hip Score (pain and function) preoperatively and postoperatively at 6, 12 months, and evaluated patient’s pain by JOA pain scoring system and postoperative subjective satisfaction. Results: The mean score of HHS improved 15 points with conservative treatments and 32 points with hip arthroscopy. In 4 cases of conservative treatment, there was 1 scale improvement of JOA pain scoring system. In arthroscopic partial labrectomy, all cases were improved to more than 2 scale. Conclusion: We considered that acetabular labral tears occurred associated with sports injuries. So it is important to be interested in enthusiastic diagnosis and appropriate treatment for hip pain caused by sports injuries, especially about acetabular labral tears.

Objective: This study aimed to investigate the characteristics of the declination of the subtalar joint rotation axis and the structural features of the ankle joint complex such as rear-foot angle alignment and ligament laxity test between chronic ankle instability (CAI) patients and healthy control. Method: A total of 76 subjects and CAI group (N=38, age: $23.11{\pm}7.63yrs$, height: $165.67{\pm}9.54cm$, weight: $60.13{\pm}11.71kg$) and healthy control (N=38, age: $23.55{\pm}7.03yrs$, height: $167.92{\pm}9.22cm$, weight: $64.58{\pm}13.40kg$) participated in this study. Results: The declination of the subtalar joint rotation axis of the CAI group was statistically different from healthy control in both sagittal slope and transverse slope. The rear-foot angle of CAI group was different from a healthy control. Compared to healthy control, they had the structure of rear-foot varus that could have a high occurrence rate of ankle varus sprain. CAI group had loose ATFL and CFL compared to the healthy control. Conclusion: The results of this study showed that the deviation of the subtalar joint rotation axis and the structural features of the ankle joint complex were different between the CAI group and the healthy control and this difference is a meaningful factor in the occurrence of lateral ankle sprains.

The main objective of this study was to investigate the effects of exercise on serum insulin and leptin levels and GLUT-4 and VAMP-2 in skeletal muscles from the pregnant rats. F344 rats were randomly divided into four groups (n = 15 in each group): control group (CG), pregnant group (PG), pregnant running group (PR), and pregnant swimming group (PS). From the 15th day of pregnancy, animals in the running group were forced to run on treadmill for 30 min with a light intensity, while those in the swimming group were forced to swim in swimming pool for 10 min once a day for 6 consecutive days. The present result demonstrated that in pregnant rat group, serum insulin levels significantly in-creased and leptin levels significantly decreased. Skeletal GLUT-4 and VAMP-2 protein expression was significantly decreased in pregnant rats compared to non-pregnant rats. However, matenal running during gestational period alleviated pregnancy-induced changes in plasma insulin and leptin levels, and it significantly enhanced skeletal GLUT-4 and VAMP-2 protein expression. From those results, it can be suggested that running exercise during gestational period may improve glycemic control by up-regulating GLUT-4 and VAMP-2 protein expression.

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.

Elbow joint injuries during exercise mostly occur by repeated stress to the joint than direct trauma. A pitcher who uses his arm above his head is most likely to be injured. So learning the right way to exercise and gaining the strength by maturating the body are essential for diminishing the chance of injury. On lateral ulnar tendon injury, which is most commonly injured area on elbow joint, pitchers generally complain of pain in arm movement above head and reduction of velocity, accuracy, and number of pitching. When there is pain on upper arm in harsh using, the stress fracture must be thought and epicondylar physis fracture of medial arm can occur by repeated abduction stress and contraction of flexors on forearm on children with immature skeleton. Osteochondritis dissecans of capitullum occur in young athletes who use there upper limb continuously lifting weights and gym work. And stress of abduction-extension includes damage of soft tissue and bone components, post medial crush syndrome, lateral ulnar ligament injury, extensor-abductor injury, stress of radius- capitullum are in this category.

Clinical conditions causing the lower leg injury and pain in athletes include acute injuries which are acute compartment syndrome, acute strain injury, contusion, muscle cramps, and chronic injuries which are chronic exertional compartment syndrome, achilles tendinitis, shin splints and stress fractures. Most injuries occur during running, jumping and playing soccer. Many of these conditions relate to overuse, increased strength, training errors and environment. It is necessary to know the cause of injuries and treatment methods to prevent the sports related lower leg injuries.
