본 연구의 목적은 지지 면이 다른 조건(안정, 상지 불안정, 하지 불안정, 상하지 불안정)에서의 푸시업 플러스운동이 어깨 안정근의 근 활성도에 미치는 영향을 비교 하는 것이다. 본 연구에서는 18명의 정상인이 자발적인 참여를 했다. 측정 방법은 지지 면이 다른 조건에서 푸시압 플러스를 수행 하는 동안 위세모근, 큰가슴근, 앞톱니근을 표면 근전도로 기록 하였다. 연구 대상자에게는 총 7일 동안 측정을 실시하였다. 결과 값은 푸쉬업 플러스를 실시한 실효치 값의 평균으로 제시하였다. 분석 방법은 반복 측정된 일원배치 분산분석을 이용하였다. 그 결과 위세모근과, 큰가슴근은 다른 조건의 지지 면과의 비교에서는 유의한 차이가 나타나지 않았다(p>.05). 하지만 앞톱니근에서는 상하지가 불안정한 조건일 때 푸쉬업 플러스 운동을 하는 동안 근 활성도가 가장 많이 향상되었다(p<.05). 따라서 본 연구에서는 어깨의 안정성을 향상시키기 위한 푸쉬업 플러스 운동 방법으로는 상 하지가 모두 불안정한 지지 면을 제공 할 때 가장 효과적 이였다.

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.

Purpose : The purpose of this study is to examine the muscle activity of shoulder stabilization according to change of supporting base interval between push-up bend and push-up plus position and is to prevent or treat a shoulder injury by the most effective exercise for rehabilitation. Methods : This study analyzed the muscle activity according to change of supporting base interval between push-up bend and push-up plus movement. The participants without neuromuscular disease were 25 students - 12 males and 13 females - all twenty or over and the surface electrode of EMG attached on pectoralis major, triceps long head, middle trapezius, lower trapezius, serratus anterior and latissimus dorsi. The process has practiced 3 sessions of supporting base interval - narrowing interval, two shoulder interval, broad interval - by push-up bend and push-up plus movement. Result : 1. The muscle activity of pectoralis major was significantly increased according to narrow interval of supporting base on push-up plus movement and was significant difference(p<.05). 2. The muscle activity of biceps was significantly increased according to narrow interval of supporting base on push-up bend movement(p<.05). 3. The muscle activity of middle or lower trapezius was a difference according to change of supporting base on push-up bend and push-up plus movement but was not significant difference. 4. The muscle activity of serratus anterior was significantly increased according to broad interval of supporting base on push-up bend movement(p<.05). 5. The muscle activity of latissimus dorsi was significantly increased according to broad interval of supporting base on push-up bend movement(p<.05). Conclusion : These results lead us to the conclusion that push-up bend exercise have the effect of muscle strength of biceps on narrowing interval, of serratus anterior or latissimus dorsi on broad interval and push-up plus exercise have the effect of muscle strength of pectoralis major on narrowing interval of support base.

Push-up plus has been advocated for increasing the activity of the serratus anterior muscle, the most critical scapular stabilizer. However, no previous study has reported the possibility of compensatory motion on the part of the pectoralis major, which could substitute for the action of the serratus anterior during push-up plus. The aim of the current study was to investigate the immediate effect of electromyography (EMG) biofeedback of the pectoralis major muscle on the pectoralis major, upper trapezius, and serratus anterior muscles during push-up plus. Fourteen healthy young subjects voluntarily participated in this study; each subject performed push-up plus from the quadruped position, in two conditions (i.e., with or without visual and auditory biofeedback). Surface EMG was used to measure pectoralis major, serratus anterior, and upper trapezius activity. A paired t-test was used to determine any statistically significant difference between the two conditions. Additionally, effect size was calculated to quantify the magnitude of EMG biofeedback in each muscle. Visual and auditory feedback reduced pectoralis major muscle activity significantly (p=.000) and increased the serratus anterior muscle activity significantly (p=.002), but did not induce a significant difference in upper trapezius muscle activity (p=.881). Thus, it is concluded that the visual and auditory feedback of pectoralis major muscle activity can be used to facilitate serratus anterior muscle activity during push-up plus.

This study was carried out to compare the muscle activities of the shoulder stabilizers between persons with and without winging scapular during push-up plus exercise (adds the scapular protraction to the general push-up exercise). For this study, eleven males with winging scapular and eleven healthy males were recruited. Surface electromyographic (EMG) activity was recorded from the serratus anterior, upper trapezius, lower trapezius, infraspinatus, and pectoralis major while the subjects performed the push-up plus. Each push-up plus was subdivided into three phases according to the elbow position which was measured using the 3-D motion analysis system: elbow flexion (EF), elbow extension (EE), and shoulder protraction phases (SP). Two-way repeated measure ANOVA (phase ${\times}$ group) were used for statistical analysis. There was significant phase by group interaction only on the EMG composition ratio of the serratus anterior (p>.05). The EMG composition ratio of the serratus anterior was significantly higher in SP than in either EF or EE however, it was not different between winging scapular and normal groups. For both groups, the EMG composition ratio of upper trapezius, lower trapezius, and pectoralis major was significantly different across the phases of push-up plus, but the infraspinatus EMG composition ratio was not. For both groups, in EF and EE phases, the EMG composition ratio of both pectoralis major and serratus anterior were relatively higher than that of other muscles. However, in both groups, the EMG composition ratio of the serratus anterior became much more predominant than that of the pectoralis major. In addition, infraspinatus activated greater than pectoralis major. These results showed that the push-up plus exercise is effective to selectively strengthen the serratus anterior for both individuals with and without winging scapular, but not equally effective for other shoulder stabilizers.
