초록

본 연구의 목적은 세 가지 가방 휴대 방법에 따라 세 가지 가방의 무게를 달리하여 보행하는 동안 신체의 압력중심점의 변위와 보행률의 변화를 분석하고자 2013년 6월 3일부터 2014년 1월 20일까지 시행하였다. 38명의 건강한 성인(평균 연령: $26.10{\pm}5.32$세, 연령 범위: 22-30세)이 본 연구에 참여하였다. 첫 번째 조건은 한쪽 어깨에 가방을 메고 보행하였고, 두 번째 조건은 한쪽으로 가로질러 가방을 메고 걸었으며, 세 번째 조건은 양쪽 어깨에 가방을 메고 걸었다. 보행의 운동 형상학적 변수와 보행 시 압력중심점의 변위를 측정하기 위하여 3차원 동작분석기와 지면 반력기를 사용하였다. 각 세 가지 조건에 모든 대상자가 참가하였고, 모든 대상자는 각각 세 가지 조건에서 3kg, 5kg, 7kg의 무게를 지닌 가방을 휴대하여 6m를 걸었다. 본 연구 결과, 양쪽 어깨로 가방을 메고 걸을 때 3kg, 5kg, 7kg의 가방의 무게에 따라 전-후 및 내측-외측 방향의 압력중심점과 보행률 변수에서 통계학적으로 유의한 차이가 있었다. 따라서 양쪽 어깨에 가방을 메고 걷는 것이 다른 조건보다 더 효율적으로 보행할 수 있을 것으로 사료된다.

This study examined the changes in the center of pressure (COP) and cadence according to three types of bags carried and three different bag weights. The experimental period was from June 3, 2013 to January 20, 2014, and thirty eight healthy adults (mean age: $26.10{\pm}5.32$ years, age range: 22-30 years) volunteered under three conditions. In the first condition, the subjects wore a bag over one shoulder and they walked. In the second condition, they carried a bag across the shoulder and walked. With the third condition, they carried a backpack using both shoulders and walked. 3-Dimentional motion analysis system and a force plate were used to measure the kinematic parameters of gait and COP displacement during gait. Each subject walked 6 meters carrying a 3kg, 5kg and 7kg bag under all three conditions. The COP of the antero-posterior and medio-lateral, and cadence variable were significantly different according to the bag weight of 3kg, 5kg and 7kg. These findings suggest that walking while carrying a backpack using both shoulders is more effective on the changes in COP and gait of adults than the other conditions.
