GOLF SWING 동작의 운동역학적 분석을 통한 종단적 연구

Abstract

This study aimed to analyze basic physical fitness after physical fitness training program in stages for two years, calculate major biomechanical kinetic kinematic and variables of the whole aspects including power in swing, physical articulation, club movement and driver swing using 3D image analysis and force platform longitudinally, examine characteristics of important variables by conducting pre- and post-analysis in each training and provide quantitative data necessary for effective training of coaches and athletes. Subjects of research were 3 male amateur golfers and when extensive physical fitness training and technical training were tried, biomechanical kinetic and kinematic analysis for improving accuracy of ball and distance was made. As the results of analyzing the data, the following conclusions were obtained; 1) Sway that hip joint was pushed out to right in the first phase was shown and rotation of hip joint and left and right movement through physical and technical training contributed to increase of momentum in the 3rd and the 5th phases. 2) In impact of left and right axis (Y axis) from the center of body kept low change of speed and shift effects for increasing speed of club head in impact were great. 3) Cocking angle was very effective through extensive physical and technical training and strong and accurate impact was performed by rotation of rotational angle of hip joint in impact. 4) When downswing was done in the 5th phase, natural cocking was kept by rotation of body. 5) Much momentum was delivered to club in impact by transferring center of body and weight support to left. 6) Basic physical fitness and distance were improved through extensive physical training. 7) Momentum and accuracy were improved through extensive technical training. With the above conclusions, this study suggested that the following research should be performed in the future. 1) Since this study was conducted at laboratory, it didn't explain characteristics of field clearly. Thus future researches must examine differences between laboratory and field. 2) To verify effects of physical training, understanding of exertion and aspects of muscular fitness is needed and research on utilizing EMG and isokinetic equipments must be conducted. 3) Use of high speed camera to get detailed kinetic data in impact is needed. 4) Extensive researches related to characteristics of golf club are necessary.
