엎드린 자세에서 엉덩관절 폄 동작 시 외적 부하가 복부 근육의 두께 변화에 미치는 영향

Abstract

The purpose of this study was to study the effect of external loads on the thickness change of the transverse abdominis, intra oblique muscle, and extra oblique muscle when prone hip extension with knee flexion. This study was conducted on 25 healthy adults, and prone hip extension with knee flexion was performed with 0kg, 1kg, and 2kg of sandbags worn on the ankles in a prone position. The change in muscle thickness was measured using ultrasound equipment. The thickness of the transverse abdominis and internal oblique muscles increased significantly when prone hip extension was performed with an external load applied rather than prone hip extension without an external load. There was no significant change in muscle thickness of external oblique muscle. We propose that providing an external load when performing prone hip extension is more effective for activation of deep abdominal muscles.
