Abstract

The purpose of this study unit a Quadrupedal position of limbs due to changes in the thickness of the trunk muscles to find out, by comparing the difference in muscle activity fours spinal stabilization devices do you need to choose an effective stance is to provide the data. The subjects C # 29 University students healthy adults were recruited. The Rectus abdominis muscle and the transversus abdominis and internal oblique abdominal muscle, external oblique abdominal muscle should be measured. The results of this study Lt. IO, EO, TrA, Rt. TrA, Muscle showed significant differences among the positions. The study reveals that the exercises in Quadrupedal position can activate trunk muscles and the degrees of muscle activities can vary according to the angle.

본 논문은 네발기기 자세에서 사지의 각도 변화에 따른 몸통 근육들의 두께를 알아보고 근육활성의 차이를 비교하여 네발기기에서 행하는 척추 안정화를 위한 효과적인 자세를 선택하는데 필요한 자료를 제공하고자 한다. 연구대상은 건강한 대학생 29명으로 하였다. 실험을 위해서 배가로근과 배속빗근, 배곧은근과 배바깥빗근을 측정하였다. 근육의 두께측정 및 디지털 영상분석을 위한 초음파 영상 수집은 초음파 영상장치(Mylav25gold, Esaote, Italy)를 사용하였다. 연구결과 왼쪽 배바깥빗근과 배속빗근, 배가로근 간 두께 변화와 오른쪽 배가로근의 두께 변화에 각도 간의 유의한 차이가 있는 것으로 나타났다. 이 연구는 근육활성의 정도와 몸통 근육들을 활성화하기 위해 네발기기자세에서의 운동이 각도에 따라 다양한 결과를 보인다는 것을 나타낸다.
