Purpose: This study aims to verify the effectiveness of acute anodal transcranial direct current stimulation (A-tDCS) using Halo Sport headset device on golf performance in professional golfers. Research design, data, and methodology: Eight professional golfers who voluntary participated in high-level golf tournaments were recruited in this study. They attended one single-session intervention which was stimulated by Halo Sport headset device (n=8). The A-tDCS halo sport session lasted for 20 minutes and stimulated on the motor control area of the cortex (M1). Four golf swing performance tasks (driver, iron, 100-yard shot, 50-yard shot) were performed before and after halo intervention. Key indicators of golf swing performance (Club Speed, Face Angle, Ball Speed, Smash Factor, Spin Rate, Side, Carry, Total) were collected by Trackman launch monitor. Results: In Halo session, there were no found statistical significance in driver, iron and approach (100, 50 yards) after intervention (P<0.05). Even some of variables (face angle, smash factor, carry and total distance) in driver, distance accuracy of 100 yards and direction accuracy of 50 yards were slightly improved tendency, but it was not significant (P<0.05). Meanwhile, there was any enhance all of variables in iron. Conclusions: As a result, the current study concludes that the acute A-tDCS halo sport intervention has no effect on the positive golf performance improvement for professional players. Further implications were discussed.

본 연구에서는 골프 드라이버 스윙 시 운동역학적 변인들이 비거리와 어떠한 관련성이 있는지를 분석하는 것이 목적이었다. 연구대상자는 신체 건강한 15명의 KPGA 골프 선수들이 참여하였다. 8대의 VICON 모션 캡쳐 카메라(250 Hz), 2대의 지면반력기(1000 Hz), 그리고 Trackman을 이용하여 운동학적 및 운동역학적 자료를 수집하였으며, 통계 분석은 Pearson 상관관계를 실시하였다. 드라이버 비거리와 볼 스피드, 클럽 헤드 스피드, 엑스 펙터, 그리고 지면반력 간 유의한 상관관계가 나타났으나, 스매쉬 팩터와 무릎 토크는 비거리와 상관관계가 나타나지 않았다. 볼 스피드, 클럽 헤드 스피드, 엑스 펙터, 지면반력은 비거리에 영향을 미치는 것으로 나타났으나, 스매쉬 팩터와 무릎 토크는 비거리에 영향을 미치지 않는 것으로 나타났다.

Objective: The purpose of this study was to analyze the effects of club head and golf ball kinematics and body alignment according to the swing plane during golf driver swing. Method: Sixteen college golfers participated in this study. Kinematic data of the club head and golf ball were collected using golf swing analysis system (Trackman Ver. 3e). The body alignment variables were collected using 8 motion capture system. An Independent samples t-test was used for comparison between the Out-to-In group and In-to-Out group, and the statistical significance level was set at .05. Results: For the club head related variables, club path and club face angle showed higher values in Out-to-In swing plane than In-to-Out swing plane. For the kinematic variables of the golf ball, the total distance showed a higher value in the In-to-Out swing plane than that of the Out-to-In swing plane. For the body alignment, the In-to-Out swing plane showed higher values than the Out-to-In swing plane for the pelvis rotation angle and trunk rotation angle. Conclusion: This study suggest that it would be more effective to use the In-to-Out swing plane for increasing the total distance during the golf driver swing.

The purpose of this study was to develop the Functional golf inner-wear by preventing the injuries and enhancing the performance of the Golf swing by checking the influence of the wearing of the functional golf inner-wear considering golf characteristics on the Swing trajectory and Shot distance. Functional inner-wear effective for golf swing was manufactured using the sports taping method. Changes in driver and iron swing before and after wearing the functional golf inner-wear manufactured in this way were measured using trackman equipment. Measurement variables were limited to Club Speed, Attack Angle, Club Path, Ball Speed, Smash Factor, and Priority. Before and after wearing functional golf inner-wear, there were statistically significant differences in driver club speed, iron club speed, driver etch angle, iron club pass, driver ball speed, driver smash factor, iron smash factor, driver carry, iron carry, and right shoulder joint proprioceptive sensory ability. As a result, functional golf inner-wear is effective for ball speed, impact, and carry by increasing club speed and efficient swing. Future research will focus on the development of functional golf that can improve the swing ability in a short game that plays an important role in the golf game through various sports taping grafting technique, textile, special material, film, Research on functional golf inner-wear.

Functional inner-wear being currently sold is being made without regard to the characteristics of various sports events. The purpose of this study is to identify this problem and to investigate the effect of sports taping on golf swing when wearing functional inner-wear. The subjects of this study were 8 male golfers belonging to Korea Professional Golf Association, and Launch monitor and Trackman were used to find out golf club action, ball pitch, distance, etc. There are three types of clubs: driver, wood, and iron, and the first experiment was carried out using only functional inner-wear. In the second experiment, we experimented with functional inner-wear after sports taping, and we compared and analyzed the distance depending on each experiment, the speed of the ball and the club, and the accuracy of the club face. The results of the study were as follows. As a result of driving distance, according to the presence of sports taping on functional inner-wear, there was a statistically significant difference in the driving swing and wood swing, for club and ball speed, there was a statistically significant difference only in the driving swing. Regarding the accuracy by the presence of sports taping on inner-wear, there was a statistically significant difference in the driving swing, wood swing, and iron swing. In conclusion, the sports taping in the functional inner-wear had a positive effect on golf performance improvement, and we hope that golf inner-wear these two specifications combing will be developed in the future.

본 연구의 목적은 골프 입문자들을 대상으로 12주간 훈련을 통하여 수행한 스윙에서 유효타에 미치는 변인들을 분석하고, 이를 통하여 골프 입문자들의 페어웨이 안착을 위한 유효타 요인의 기초자료를 제공하고자 한다. 본 연구의 대상은 골프 경험이 없는 입문자로 대학생 20명이 연구에 참여하였다(연령: 21.35±1.69yrs, 신장: 176.75±7.99cm, 체중: 70.70±9.76kg). 모든 대상자에게 12주간 골프 지도법에 따른 프로그램을 실시하였고, 12주차에 트랙맨 4를 이용하여 골프 스윙 시 유효타에 미치는 변인들을 산출하였다. 트랙맨 자료는 클럽 변인과 볼 변인으로 구분하여 유효타에 영향을 미치는 변인을 알아보기 위하여 이분형 로지스틱 회귀분석을 실시하였다. 클럽 변인에서 높은 다이나믹로프트(p<.01)와 낮은 페이스앵글(p<.05)은 유효타에서 나타났고, 볼 변인에서 빠른 볼스피드(p<.01), 큰 스매시팩터(p<.001), 높은 런치앵글(p<.001), 많은 스핀레이트(p<.001)도 유효타에서 나타났다. 클럽 변인의 이분형 로지스틱 회귀분석 결과, 클럽스피드(p<.05)와 다이나믹로프트(p<.01)가 증가하면 유효타의 가능성이 증가하였고, 페이스앵글(p<.001)이 증가하면 유효타의 가능성이 감소하였다. 클럽 변인에서 유효타의 영향력은 다이나믹로프트, 페이스앵글, 클럽스피드 순으로 나타났다. 볼 변인에서는 런치앵글(p<.05)이 증가하면 유효타의 가능성이 증가하였고, 런치디렉션(p<.05)이 증가하면 유효타의 가능성이 감소하였다. 볼 변인에서 유효타의 영향력은 런치앵글, 런치디렉션 순으로 나타났다. 결과를 토대로 유효타의 확률을 증가시키기 위한 조건으로, 지속적인 연습을 통하여 스윙 시 높은 다이나믹로프트와 낮은 페이스앵글 구사를 통한 클럽스피드 증가가 필요하고, 이를 통하여 런치앵글 증가와 런치디렉션 감소를 통하여 유효타의 확률이 증가될 것으로 사료된다.
