보행 시 하이힐 굽 높이에 따른 구간별 차이를 비교하고, 하지관절의 가동범위가 보행 시간에 미치는 영향을 알아보고자 하였다. 20대 여대생 10명이 연구에 참여하였고, 굽 높이에 따라 3차원 보행분 석을 통하여 변인을 산출하였다. 통계방법으로 세가지 굽높이에 따른 차이는 일원변량분석을 실시하였고, 보행시간이 하지관절에 미치는 영향은 다중회귀분석을 실시하였다. 연구결과로 보행 시 구간 2는 굽이 높을수록 보행시간이 길게 나타났지만, 구간 3은 굽이 높을수록 보행시간이 짧게 나타났다. 보행시간이 하지 관절 가동범위에 미치는 영향을 분석한 결과 구간 2는 1 cm에서 발목관절, 무릎관절, 5 cm는 발목관절의 가동범위가 클수록 보행시간이 길어졌다. 구간 3은 1 cm에서 고관절 가동범위가 클수록 보행시간이 길어 졌고, 10 cm는 발목관절 가동범위가 작을수록 보행시간이 길어졌다. 따라서 굽 높이 신발의 경우 발목관절의 제어가 중요성이 변인으로 판단된다. The purpose of the study was to compare the differences among phases accoring to the gait time on the heel height during gait, investigate the effect on ROM of the lower limb on gait time. Ten female college students in their 20s participated in the study, and variables were calculated through 3D gait analysis on height of heel. As a statistical method, one-way ANOVA was performed for the differences between the three heel heights, and multiple regression analysis was performed to determine the effect of gait time on the ROM. As a result of the study, phase 2, the higher the heel, the longer the gait time, but phase 3, the higher the heel, the shorter the gait time. As a result of analyzing the effect of gait time on the ROM of the lower limb, in phase 2, the greater the ROM for the ankle and knee joint in 1 cm, and for the ankle joint in 5 cm, the longer the gait time. In phase 3, the greater the ROM for the hip joint in 1 cm, the longer the gait time, and the smaller the ROM for the ankle joint in 10 cm, the longer the gait time. Therefore, in the case of high-heeled shoes, it is suggested that the control of the ankle joint is important.

윤세진(Se-Jin Yoon),설정덕(Jeong-Dug Sul),우병훈(Byung-Hoon Woo) 한국응용과학기술학회 (구.한국유화학회) 2021 한국응용과학기술학회지 Vol.38 No.2

본 연구의 목적은 골프 스윙 시 3가지 스탠스에서 클럽헤드 스피드와 볼의 정확성을 유지하기 위한 신체 전략을 하지의 운동학적 변인과 지면반력 변인을 통하여 알아보고자 하였다. 연구의 대상은 공식 핸디캡이 2인 남자골프선수 10명으로 하였다. 모든 대상자들은 스탠스 조건(스퀘어, 오픈, 클로즈드)에 따라 어드레스 자세를 유지한 후 스윙을 수행하였다. 3차원 동작분석 시스템과 지면반력기를 이용하여 각스탠스에 따라 7번 아이언 풀스윙을 수행한 결과를 산출하였다. 연구결과로 신체중심의 변위, 고관절 각변 위, 무릎관절 각변위는 차이가 나타나지 않았다. 발목관절 각변위는 어드레스부터 다운스윙까지 왼쪽에서 오픈 스탠스가 저측굴곡이 크게 수행되었고, 오른쪽에서 클로즈드 스탠스에서 저측굴곡이 크게 수행되었 다. 지면반력에서 전후, 수직은 차이가 없었지만, 어드레스부터 테이크백까지 왼발은 오른쪽 방향, 오른발은 왼쪽 방향의 힘이 오픈이 클로즈드 스탠스보다 크게 나타났다. 결론적으로 다양한 스탠스에도 불구하고, 임팩트 시 동일한 자세를 유지하는 것이 클럽헤드 스피드와 볼의 방향에 긍정적으로 작용되는 것으로 판단 된다. The purpose of this study was to investigate the body s strategy through kinematic variables of the lower extremities and ground reaction forces to maintain the club-head speed and ball accuracy despite the three stances during the golf swing. Ten male golfers who official handicap two were participate in the experiment. All subjects performed swing after maintaining the address posture according to stance conditions(square; SS, open: OS, closed: CS). Using a 3D motion analysis system and force plateform, the results were calculated with the 7-iron full swing each stance. In result, there was no difference in center of displacement, and left and right hip and knee joint angle displacement. Left ankle joint was largely plantar-flexed in OS, and right ankle joint was largely performed in CS from the address to the downswing. From address to take-back, right foot had a large left direction and the left foot had a right direction were greater in OS than in CS. Therefore, despite various stances, maintaining the same posture at impact is thought to have a positive effect on club head speed and ball direction.

The research was conducted in order to provide necessary baseline data for early prevention of yips and to reduce the recovery period by identifying various causes and symptoms of yips through in-depth analysis the causes of yips that were experienced by professional golfers. To achieve these goals, in-depth interviews were organized with selected five members of professional golfers from KPGA and KLPGA whom have experienced yips, and analyzed the collected data accordingly to qualitative research method procedure. The result has shown that the causes for professional golfers to suffer from yips are pressure due to expectations from peers after professional initiation, changed lifestyle upon joining college, personal issues, family environment, swing-correction, and long-term break from field. Yips may be a serious strike for professional golfers’ athlete’s life, so it must be overcome as soon as it is possible. The most important method in resolving yips is having a positive attitude to understand the cause of the yips, and self-will to overcome it. Moreover, it is demanded for further efforts to reveal clearer and practical facts through cognitive approach with collaboration of quantitative and qualitative research on the causes of yips of professional golfers.
