The purpose of this study was to examine the eye movement depending on putting distance and accuracy in golf putting. The subjects were semi-professional 5 golfers. Golfers had performed golf putting on 2 m and 15 m distances. Visual search had used in order to examine the eye movement in success and failure of putting by eye tracker (Dikablis 2.0). During golf putting, eye movement analysis had analyzed on the ball and the hole of putting distance and accuracy. Data were analyzed with analysis of variance for repeated measures using SPSS ver. 15.0 program. Visual search to distance and accuracy on ball were as followed. Duration was significant differences in putting distance. Number of glances was significant differences in accuracy. Percentaged glance proportion was significant differences in putting distance. Glance frequency was significant differences in putting distance. Visual search to distance and accuracy on hole were followed. Total glance time and number of glances were significant differences in putting distance. Mean glance duration was significant differences in putting distance, accuracy, and between interaction. Percentaged glance proportion was significant differences in putting distance and between interaction. Maximal glance duration was significant differences in putting distance, accuracy, and between interaction. Minimal glance duration was significant differences in accuracy, and between interaction. Glance frequency was significant differences in between interaction. This study will be expected to be utilized for putting performance improvement as a basis for developing an exercise program.

Symptoms of basal rot occurred sporadically on creeping bent grasses growing at a golf course in Hampyeong, Korea in April 2007. Ten isolates of Microdochium sp. were obtained from leaves and crowns of the diseased bent grasses. All isolates were identified as Microdochium bolleyi based on morphological, cultural, and molecular characteristics. This is the first report on M. bolleyi associated with basal rot on creeping bent grass in Korea.

OBJECTIVE: To evaluate if shoulder and pelvic angular velocities differ at impact or peak magnitude between professional and amateur golfers. Golf swing rotational biomechanics are a key determinant of power generation, driving distance, and injury prevention. We hypothesize that shoulder and pelvic angular velocities would be highly consistent in professionals. METHODS: Rotational velocities of the upper-torso and pelvis throughout the golf swing and in relation to phases of the golf swing were examined in 11 professionals and compared to 5 amateurs using three-dimensional motion analysis. RESULTS: Peak rotational velocities of professionals were highly consistent, demonstrating low variability (coefficient of variation [COV]), particularly upper-torso rotational velocity (COV=0.086) and pelvic rotational velocity (COV=0.079) during down swing. Peak upper-torso rotational velocity and peak X-prime, the relative rotational velocity of uppertorso versus pelvis, occurred after impact in follow-through, were reduced in amateurs compared to professionals (p=0.005 and p=0.005, respectively) and differentiated professionals from most (4/5) amateurs. In contrast, peak pelvic rotational velocity occurred in down swing. Pelvic velocity at impact was reduced in amateurs compared to professionals (p=0.019) and differentiated professionals from most (4/5) amateurs. CONCLUSION: Golf swing rotational velocity of professionals was consistent in pattern and magnitude, offering benchmarks for amateurs. Understanding golf swing rotational biomechanics can guide swing modifications to help optimize performance and prevent injury.

OBJECTIVE: To evaluate the effects of stretching exercise on the head speed of golf club and driving distance. METHOD: 58 male golfers (20 professionals, 22 amateurs, 16 beginners) were included in the study. They carried out stretching exercise programs related to muscles of trunk, upper and lower extremities for 5 and 30 minutes. The head speed of golf club and driving distance were measured before and after the stretching exercise. The effects of stretching exercise programs on the head speed and driving distance were assessed. RESULTS: The head speed increased significantly in amateur and beginner groups after 30 minutes' stretching. In professional group, the head speed increased significantly after 5 minutes' stretching, but no more increment was found after 30 minutes' stretching. Driving distance increased significantly in all groups after 5 minutes' stretching. After 30 minutes' stretching, much more increment was found compared to 5 minutes' stretching. CONCLUSION: Sufficient stretching exercise program before golf swing can increase the head speed of club and driving distance. We recommend stretching exercise to improve golf performance.

OBJECTIVE: To determine whether there is side to side difference of the trunk rotation muscle in Korean male professional golf players. Healthy controls who did not play golf were also evaluated and compared with professional golf players. METHOD: Fifty-one professional golf players and 50 healthy controls participated in this study. Bilateral isokinetic trunk rotation strength that represented the aiming side and non-aiming side trunk rotator function in a golf swing and other parameters were evaluated using the Biodex System III Isokinetic Dynamometer at angular velocities of 30, 60, and 120 degree per second. RESULTS: The professional golf players' peak torque and total work on their aiming sides were significantly higher than on their non-aiming side at all angular velocities. Additionally, the golf players' peak torque on their aiming side was significantly higher than those of the healthy controls only at the 60 degree per second angular velocity, but there was a slight and consistent trend in the others. Finally, the difference between the aiming side and the non-aiming side of the professional golf players and the healthy controls was also significant. CONCLUSION: The aiming side rotation strength of the male professional golf players was higher than that of non-aiming side. The controls showed no side-to-side differences. This finding is attributed to the repetitive training and practice of professional golf players. A further study is needed to investigate if the strengthening of the trunk rotation muscle, especially on the aiming side, could improve golf performance.

Golf has become an increasingly popular sport worldwide. Although often perceived as a leisurely activity, golf can be a demanding sport, which can result in injury, usually from variety of reasons. While the majority of injuries in golf are attributable to overuse, acute traumatic injuries can also occur. As the body is directly linked to the golf club, the upper extremities are especially prone to injury. This article focuses on the upper extremity injuries in golf, including a discussion of the epidemiology, cause, diagnosis, treatment, and prevention of injuries occurring in shoulder, elbow, wrist, and hand.

Golf has become an increasingly popular sport worldwide. In a survey done by the National Statistical Office of Korea in 2004, it is shown that 3.3% of Koreans who are 15 or older, which is about 1.27 million people, have played golf. Unfortunately, despite the rising popularity of golf, the research on the prevention and treatment of golf-related injuries has been quite lacking in Korea. In terms of sports injuries, golf is considered to have a medium-class injury potential, with most injuries resulting from overuse but other causes such as lack of flexibility, unbalanced muscles, failure in condition management, and inadequate stretching and warm-up/cooldown exercises are also possible. Furthermore, many golfers tend to force themselves into more exercises and rounds even when not having been fully recovered from the initial injury, giving rise to secondary injuries. The prevalence of golf-related injuries varies greatly among researchers, but even with the average of 50%, it can be assumed that about 600,000 Korean golfers are suffering from various kinds of pain and discomfort. The aim of this review is to understand the causes of gold-related injuries and the strategies for the treatment and prevention thereof.

Golf is low demanded activity and becoming more popular. But it often occur problems in back, shoulder, elbow and wrist. Golf injuries in professional golfer are related overuse and frequency, while in amateur are related wrong swing technique. Also muscle activities in swing are different between professional and amateur. We report partial tear of pronator teres in middle aged amateur golfer with literatures.

OBJECTIVE: To investigate the causes and characteristics of golf-related shoulder injuries in Korean amateur golfers. METHODS: Golf-related surveys were administered to, and ultrasonography were conducted on, 77 Korean amateur golfers with golf-related shoulder pain. The correlation between the golf-related surveys and ultrasonographic findings were investigated. RESULTS: The non-dominant shoulder is more likely to have golf-related pain and abnormal findings on ultrasonography than is the dominant shoulder. Supraspinatus muscle tear was the most frequent type of injury on ultrasonography, followed by subscapularis muscle tear. Investigation of the participants' golf-related habits revealed that only the amount of time spent practicing golf was correlated with supraspinatus muscle tear. No correlation was observed between the most painful swing phases and abnormal ultrasonographic findings. Participants who had not previously visited clinics were more likely to present with abnormal ultrasonographic findings, and many of the participants complained of additional upper limb pain. CONCLUSION: Golf-related shoulder injuries and pain are most likely to be observed in the non-dominant shoulder. The supraspinatus muscle was the most susceptible muscle to damage. A correlation was observed between time spent practicing golf and supraspinatus muscle tear.
