골프에서 피치 샷 거리에 영향을 미치는 피칭 동작의 역학적 특성

Abstract

The purpose of this study was to examine the biomechanical factors about controlling distance by analyzing the biomechanical variable of pitch shots within 100 yards. For the study, each of the subjects who are the 9 professionals were picked out to measure distances of 100%, 75%, 50%, and 25% of sand wedge full-swing. To analyze the biomechanical variables of the subjects, We took the scene analysis, foot-pressure analysis. The data were analyzed utilizing one-way ANOVA with repeated measures. The Turkey's method was used to prove the results and the study was experimented within the statistical level of p<.05. Followings are the conclusions obtained by the experiments: In case of the address poses, the stance width and left foot open angle got smaller in order of the distances of 100%, 75%, 50%,25%. In case of the swing, the whole movement time and turning angle of left arm ․ club ․ shoulder got smaller in order of the distances of 100%, 75%, 50%, 25%, however, the angle of cocking got bigger. In the case of back swing top,the maximum force rate of left foot got heavier in order of distances of 100%, 75%, 50%, 25%. In impact, maximum club head velocity got slower in order of the distances of 100%, 75%, 50%, 25%.
