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.

The purpose of this study is to experimentally analyze swing motion with soft golf clubs and compare with that with normal golf clubs. Soft golf is newly devised recreational sport based on golf but focus on the playability for the elderly. The subject fur the experiment performed swing motion using a normal golf club and a soft golf club in turn. The swing motion of the subjects was tracked using an opto-electric three-dimensional motion analysis system. The results were compared against those obtained with a normal golf club. The range of motion was analyzed along with top head speed for two cases. It was found that higher club head speed could be achieved with reduced range of motion at lumbar joint using soft golf club when compared against the swing using regular club. The lower range of motion fur lumbar bending means reduced risk of injury at the joint. So, it is projected that we can reduce the risk of injury with soft golf while maintaining the club head speed.

There is a large number of old athletes participating golf, and the shoulder, especially the nondominant or lead arm, appears to be at greatest risk for golf-related injury during extremes of motion. To reduce and prevent the risk of injury and improve the performance of golf, golfer should understand the biomechanics of the golf swing, increase flexibility, and perform stretching and strengthening exercises regularly .

Golf has become an increasingly a popular sports for young and older ages. It has benefits of walking exercise and enjoyment of sports . However, golf is considered to be a moderate risk activity for sports injury due to traumatic origin and overuse. Golf injuries primarily affect the dorsolumbar sites , upper extremity(elbow, shoulder, wrist) and lower extremity (knee, hip, ankle). Ajustment of golf swing and conditioning programmes for preventing injuries which include muscular strengthening, flexibility and a short pregame warm up help to reduce the incidence of injury.

Objective : The purpose of this study was to describe the correlation between the activity of the muscles of upper and lower limbs of a golf driver swing according to shoulder injury. Method : The subjects were 18 professional golfers (7 male in KPGA and 11 female in KLPGA). Using surface electromyography, we evaluated muscle activities during the golf drive swing. Surface electrodes were used to record the level of muscle activity in the left Deltoid(MD), Triceps Brachii(TB), Pectoralis(PM), Trapezius(UT), Rectus Femoris(RF), Vastus Medialis Obilique(VMO), Biceps Femoris(BF), Gastrocnemius(GCM) muscles during the golfer's swing. The golf swing was divided into five phases: take away, forward swing, acceleration, early follow through, late follow through. Results : The results can be summarized as follows: MD, VMO had statistically significant difference in take away phases, GCM had statistically significant difference in acceleration phases, MD, PM, VMO had statistically significant difference in early follow through phases, PM had statistically significant difference in late follow through phases, Conclusion : Muscle activity of the 8 muscles(Deltoid, Triceps Brachii, Pectoralis, Trapezius, Rectus Femoris, Vastus Medialis Obilique, Biceps Femoris, Gastrocnemius) along the shoulder damage or absence of has shown that they are organically connected to each of the phases.

Purpose : The purpose of this study is to know sports injury aspects and relationship between exercise stress, tension, exercise habits and sports injuries. Methods : We surveyed 42 professional golf players who attended Korea Tour during the second half of the year 2010 and have sports injuries with self - assessment questionnaires. Results : According to the types, they had myalgia, tendonitis, ligament sprain in the order. According to the body parts, they had injuries in right thoracic, left cervical, left shoulder region in the order. As a result of the analysis of the sports injury frequency according to the exercise stress and tension, there were no significant differences between the high and low level group. But result of injury regions showed high tension level group showed more damages in right thoracic region (p<0.05). Exercise habits appear subjects had lots of training time, however, they used to skip the muscular strengthening exercise during the on season, but had no significant difference between sports injury frequencies and exercise habit. Conclusion : For the improvement of the athletic performance and prevention of the sports injury, warming-up, cooling-down and muscular strengthening exercise program developments are needed.

The purpose of this study is to present a caddie education program that can improve the performance of golf caddies in China by comparing and analyzing the golf caddie education programs in South Korea and China. Caddie education programs were collected from 4 golf clubs, 3 professional caddie education institutions and 8 public institutions in South Korea and 6 golf clubs and 2 professional caddie education institutions in China. The following results were obtained. Although the caddie training in China is conducted over more time and term than in South Korea, it is necessary to have an education program considering golf expertise and quality of customer service. Therefore, the caddie education program in China is composed of golf related education(golf etiquette, golf practice skill), caddie duty training(safety management, customer service and image making), and training for caddie(fitness management, injury prevention, skin care, and cost-saving etc.). In the future, the Chinese golf club industry will has a potential to develop. In order to provide a consistent and systematic education, manual training on caddie education and training on caddie master to manage caddies should be conducted.

Soft Golf is a newly developed recreational sport in our research team aimed to become a safe and easy-to-learn sport for all ages. The advantage of Soft Golf stems from lighter weight of the club and much larger area of the sweet spot. The purpose of this study is to analyze ground reaction force(GRF) and joint angle during soft Golf club and regular golf club swing. The GRF of golf swing was recorded by 3-D motion analysis system and forceplate. The joint angle of golf swing was obtained from computer simulation model. The GRF and joint angle of golf swing are used to analysis of golf swing pattern. The pattern of GRF and joint angle during soft golf club swing was similar to that during regular golf club swing. This result means that soft golf club reduces the risk of injury and has an effect on similar entertainment of regular golf.

Avulsion of spinous process, also called Clay-shoveler's fracture, is most prevalent among those engaged in hard physical labor. To the best of the author's knowledge, only one case of multiple spinous process fractures of the upper thoracic spine in a novice golfer has been reported. A 45-year-old female presented with intractable posterior neck pain. The patient experienced a sharp, sudden pain on the neck while swinging a golf club, immediately after the club head struck the ground. Dynamic cervical radiographic findings were C6 and C7 spinous process fractures. Magnetic resonance imaging revealed C6 and C7 spinous process fractures without spinal cord pathology. The patient was treated with pain medications and cervical bracing. The patient's pain gradually improved. The injury mechanism was speculated to be similar to Clay-shoveler's fracture. Lower cervical spinous process fractures can be associated with a golf swing. If the patient complains of long lasting neck pain and has a history of golf activity, further study should be conducted to rule out lower cervical spinous fracture.

Kinematic and kinetic analysis has been performed for Soft Golf swings utilizing realistic three dimensional computer simulations based on three dimensional motion tracking data. Soft Golf is a newly developed recreational sport in South Korea aimed to become a safe and easy-to-learn sport for all ages. The advantage of Soft Golf stems from lighter weight of the club and much larger area of the sweet spot. This paper tries to look into kinematic and kinetic aspects of soft golf swings compared to regular golf swing and find the advantages of lighter Soft Golf clubs. For this purpose, swing motions of older aged participants were captured and kinematic analysis was performed for various kinematic parameters such as club head velocity, joint angular velocity, and joint range of motions as a pilot study. Kinetic analysis was performed by applying kinematic data to computer simulation models constructed from anthropometric database and the measurements from the participants. The simulations were solved using multi-body dynamics solver. Firstly, the kinematic parameters such as joint angles were obtained by solving inverse dynamics problem based on motion tracking data. Secondly, the kinetic parameters such as joint torques were obtained by solving control dynamics problem of making joint torque to follow pre-defined joint angle data. The results showed that mechanical loadings to major joints were reduced with lighter Soft Golf club.
