힙 힌지 동작에 따른 둥근 어깨와 정상인의 근활성도 비교

Abstract

This study applied Hip hinge movement, a pelvic activation exercise, to round shoulder subjects and normal people based on the theory of the Anatomy train that our bodies are connected by kinesthetic chains and was executed to explore and compare muscle activity changes of the selected two groups during hip hinge movements. It was classified as round shoulder(n=9) and normal(n=9) for healthy young men in their 20s. The standard for selecting round shoulders at this point was to measure the height of the back of the shoulder bone peak from the side of the table and if the height is a ＜2.5㎝ or more, it is selected as round shoulders. The movement is to hold a rod fastening it at the back of the head, thoracic vertebrae and coccyx, then push the hips back by retracting the hip joint and get up. It is performed 15 times in a set alternating between the two sides.<BR> The results of this work show that when performing hip hinge movement, the Pectoralis major from the round shoulder group differ significantly in the left Pectoralis major(p＜.05) when the left arm is raised and showed no significant difference in muscle activity of the Deltoid posterior, Gluteus medius and Semitendinous also showed significant difference in muscle activity(p＜.05) and overall it was seen high in the round shoulder group. This produced a meaningful result in hip hinge exercises in some parts of round shoulder posture and this study is significant in suggesting different directions for future methods of exercise involving round shoulders.
