Abstract

This study aims to compare muscle activities of trunk and lower extremities according to wearing/not-wearing and forms of backpack. Twenti-six healthy adults were participated in the study. In the backpack with 10% body weight, trunk and lower extremities were measured during carrying the no backpack state(NBs), general backpack state(GBs), a decrease moment arm backpack state(DMBs). The muscle activity in a fore muscles(Obilique, Quadriceps, Tibialis anterior, Gastrocnemius) were analyzed with using wireless electromyogram measuring system. DMBs showed significant improvemet in obilique, quadriceps and gastrocnemius muscle RVC.

본 연구의 목적은 건강한 대학생을 대상으로 백팩 착용 유무 및 형태에 따른 몸통 하지 근 활성도 변인들의 차이점을 규명하는데 그 목적을 두고 있다. 26명의 건강한 성인이 연구에 참여하였다. 백팩의 무게 10%로 부하된 상태에서, 백팩을 착용하지 않은 상태, 일반적인 백팩을 착용한 상태, 모멘트 팔을 감소시키도록 고안된 백팩을 착용한 상태에서 몸통과 하지의 근활성도를 측정하였다. 배빗근육, 넙다리네갈래근, 앞정강근, 장딴지근의 근 활성도 분석을 위해 무선근전도 시스템을 사용하였다. 모멘트 팔을 감소시키도록 고안된 백팩을 착용한 상태에서 배빗근육, 넙다리네갈래근 그리고 장딴지근의 보행 구간에서 RVC에 변화가 통계학적으로 유의한 차이를 보였다. 그러므로, 백팩을 주로 사용하는 성인들에게 가방끈 조절을 적용하는 방법은 몸통과 다리근육의 활성에 긍정적인 측면을 제공한다는 것을 나타내며, 추후 가방의 디자인과 착용방법에 대한 지속적인 가방융합개발이 필요할 것이다.
