Abstract

The purpose of this study was to reveal the effect of COP variable of support feet on relative reach distance and composite score of active feet during YBT. 29 adults in their 20s(age: 24.4±3.0 yrs, height: 171.0±10.5 cm, weight: 72.1±12.1 kg, leg length: 88.2±5.8 cm) participated in the study. Using YBT, relative reach distance and composite score of active feet were calculated, and COP variables of support feet were measured on left and right support feet. Multiple regression analysis was used to determine the effect of COP variables of support feet during YBT on relative reach distance and composite score. As a result of the study, during YBT, when supporting right feet, the influence of AP COP velocity, ML COP velocity and COP velocity in posterolateral direction was significant, and when supporting left feet, the influence of AP COP velocity, ML COP velocity in posteromedial direction improved relative reach distance and composite score.

본 연구의 목적은 YBT(Y-balance test) 시 지지발의 COP 변인이 활동발의 상대도달거리와 종합점수에 미치는 영향을 밝히는 것이다. 연구의 대상자로 20대 성인 남성 26명(연령: 24.4±3.0 년, 신장: 171.0±10.5 cm, 체중: 72.1±12.1 kg 다리길이: 88.2±5.8 cm)이 연구에 참여하였다. 연구의 측정도구인 YBT를 통하여 활동발의 상대도달거리, 종합점수, 지지발의 COP 변인들을 좌우발에서 측정하여 결과를 도출하였다. YBT 시 지지발의 COP 변인이 상대도달거리와 종합점수가 미치는 영향을 알아보기 위하여 다중회귀분석을 이용하였다. 이에 따른 연구결과로, YBT 동안 오른발 지지 시 후외측 방향에서 전후, 좌우 COP속도, COP속도의 영향이 크고, 왼발 지지 시 후내측 방향에서 전후, 좌우 COP속도, COP속도의 영향으로 상대도달거리 및 종합점수를 향상시켰다.
