Abstract

본 연구는 골프스윙 시 체형별로 나타나는 운동학적 요인을 분석하여 비교함으로써 체형별 골프지도를 위한 기초자료를 제공하는데 있다. 이를 위해 현재 남자 프로골프선수 9명을 대상으로 각자의 체중과 신장 그리고 상완둘레등을 고려하여 외배엽, 내배엽, 중배엽으로 체형을 나누었다. 각자의 골프스윙동작을 비디오 카메라로 촬영하여 스윙동작을 8개의 구간으로 나누어 분석하였으며 다음과 같이 결론에 도달하였다. 골프스윙 소요시간은 내배엽형이 가장 길었으며 다음으로 중배엽형, 마지막으로 외배엽형이 가장 짧은 스윙시간을 보이고 있었다. 좌우이동변위가 가장 크게 나타나는 체형은 중배엽형이었으며, 다음으로는 내배엽형, 그리고 외배엽형이 가장 작게 움직이는 것으로 나타났다. 내배엽형은 임팩트 시 상하변위가 상승쪽으로 향하고 있었으며 내배엽형과 중배엽형은 임팩트 시 거의 일정한 높이를 유지하여 안정감을 높이는 것으로 나타났다. 상체회전각도와 골반회전각도는 임팩트 시 외배엽형의 상체와 골반이 미리 돌아가는 형태를 취하고 있어 내배엽과 중배엽형에 비해 다소 다른 특징을 보이고 있었다. 이러한 스윙에 대한 체형별 운동학적 특징을 이론을 제시함에 있어 보다 근본적인 힘의 이동을 알아야 할 필요가 있다. 따라서, 차후 연구에서는 지면반력을 이용하여 압력중심점(COP)의 분석이 함께 이루어져야 할 것으로 판단된다. This study was intended to provide basic materials for golf coaching by somatotype by analyzing and comparing the kinematic factors found in each somatotype at the time of golf swing. For this purpose, the somatotype was divided into endomorph, mesomorph and ectomorph in reference to the weight, height and upper arm circumference of each of nine professional golfers. Each of their swing motions was videotaped with the camcorder and their swing motion was analyzed by dividing it into 8 sections. The time required for the swing motion, the displacement of the center of the human body and the rotation angle of the upper body were calculated through the three-dimensional image analysis based on the DLT(Direct Linear Transformation). Based on the findings of this study, the following conclusion was drawn: The endomorphic golfers showed the longest required golf swing time, followed by the mesomorphic golfer and then the endomorphic golfer. The displacement of left-to-right movement was largest in the mesomorphic golfers, followed by the endomorphic golfers the up-to-down displacement was upward at the time of impact and that the endomorphic and mesomorphic golfers raised the sense of stability by maintaining an almost uniform height at the time of impact. As for the rotational angle of the upper body and the rotational angle of the thigh, the upper body and the thigh took a form of rotating earlier in the ectomorphic golfers at the time of impact, who showed a somewhat different characteristics compared to the endomorphic and mesomorphic golfers. It is necessary to investigate the movement of more fundamental forces in presenting the theory related to the kinematic characteristics of this swing by somatotype. Accordingly, it is thought that it is necessary to analyze the center of pressure(COP) using the ground counterforce in the future study.
