초록

The aim of this study is to systematize of golf swing plane according to trunk type of body in order to provide a guideline for accurate and consistent golf swing to golf trainer so that the trainer can teach his or her trainee the correct and suitable golf swing. In order to achieve the aim, 3 groups of representative body figure of typical Koreans were selected. Among 68 subjects, 5 of each body figure were selected whose handicap ranging between 15 to 20, and 5 trials were conducted for each subject. The test showed that the swing angles are closely related to each body type in terms of address arm angle, up swing halfway back(1) angle, swing top angle, down swing halfway back(2) angle, halfway forward angel with the exception of impact angle. The test also showed that there is correlation between each body type and joint angles in terms of left knee angle at address, left knee, shoulder and hip rotation angle at swing top, right knee angle at impact and upper body figure at address. And no correlation in terms of right knee angle, shoulder and hip rotation angle at address, right knee angle at swing top, left knee angle, shoulder and hip rotation angle at impact. This is a strong proof that the swing angles are differentiated by each body type group and tells us that the body type and figure do have a strong effect on the performance of a sports player. Specifically to a golf player, it was proved that by optimizing each body type swing plane, the swing of the player can be improved to become consistent. The main value of the study is that the golf trainer may now provide a customed golf swing lesson in accordance with the trainee's body type and vertebrae shape.
