Abstract

The purpose of this study is to examine the change to the muscle activity from the serratus anterior(SA) of 5th and 7th, upper trapezius(UT), middle trapezius(MT) lower trapezius (LT), and pectoralis major(PM) when push-up plus exercise(PUP) is performed in four postures. 25 healthy, young participants performed various PUP convergence exercise(general posture, $90^{\circ}$, $120^{\circ}$ and BOSU). The muscle activity of the shoulder stability muscles was measured using a surface EMG analysis system during various PUP convergence exercise. One-way repeated-measure of ANOVA was conducted to comparison the activity of each muscle. There was significant difference in SA7, PM, UT, and MT (p <.05) during various PUP. The muscle activity of SA7 had a significance difference between PUP and $90^{\circ}PUP$ or BOSUPUP respectively (p <.05). The muscle activity of PM had a significance difference between $90^{\circ}PUP$ and PUP or BOSUPUP (p <.05). The muscle activity of UT had a significance differnce between $90^{\circ}PUP$ and PUP or BOSUPUP (p <.05). The muscle activity of MT had a significance differnce between $90^{\circ}PUP$ and PUP and also significantly difference PUP and $120^{\circ}PUP$(p <.05). These results suggest that general PUP can be a useful to improve to scapular stabilizer muscle in who has no shoulder dysfunction.

본 연구의 목적은 4가지 자세의 푸시업 플러스(PUP) 운동 시 5번째와 7번째의 앞톱니근(SA), 위등세모근(UT), 중간등세모근(MT), 아래등세모근(LT), 큰가슴근(PM)의 근활성도를 알아보는 것이다. 25명의 대상자가 다양한 자세의 PUP 융합 운동 (일반자세, $90^{\circ}$, $120^{\circ}$, BOSU)을 실시하였다. 각 근육의 근활성도를 비교하기 위하여 반복 측정된 분산분석을 적용하였다. 다양한 PUP 융합 운동동안 SA7, PM, UT, MT에서 유의한 차이가 있었다(p <.05). SA7은 PUP 와 $90^{\circ}PUP$, BOSUPUP에서 각각 유의한 차이가 나타났다(p <.05). PM은 $90^{\circ}PUP$와 PUP, BOSUPUP에서 각각 유의한 차이가 나타났다(p <.05). UT은 $90^{\circ}PUP$와 PUP, BOSUPUP에서 각각 유의한 차이가 나타났다 (p <.05). MT는 $90^{\circ}PUP$와 PUP, $120^{\circ}PUP$, 그리고 PUP와 $120^{\circ}PUP$에서 유의한 차이가 있었다(p <.05). 본 연구 결과, 어깨의 기능부전이 없는 대상자가 어깨 안정근을 훈련할 때 일반적인 PUP가 효과적일 것이다.
