Abstract ▼ AI-Helper

Background: The serratus anterior (SA) muscle is one of the important muscles in the upward rotation of the scapula when the arm is raised. Insufficient muscle activity of the SA can cause deformation of the shoulder rhythm resulting in shoulder pathology. Objects: This study intends to compare SA and upper trapezius (UT) activity during the conventional wall-slide and push-up plus exercises for SA muscle strengthening and the scapular upward rotation (SUR) exercise. Methods: A total of 30 subjects participated in this study, and we measured the muscle activity of the SA and UT muscles during the wall-slide, push-up plus and SUR exercises. The one-way repeated ANOVA was used to compare SA and UT muscle activities during the 3 exercises. Results: During the SUR exercise, SA muscle activity was 79.88% maximum voluntary isometric contraction (MVIC), which was significantly higher than its activity during the other 2 exercises. The UT muscle activity was 47.53 %MVIC during the SUR exercise, indicating a significantly higher UT muscle activity than during the other 2 exercises. Conclusion: These findings suggest that the SUR exercise can maximize SA muscle activity to strengthen the SA while keeping UT muscle activity at an appropriate level.

문제 정의

For this reason, we have devised a method of SUR exercise that maximizes SA muscle activity while maintaining appropriate UT muscle activity. Therefore, the purpose of this study was to compare 2 previously studied conventional exercise methods for selectively increasing SA muscle activity, the WS and PUP, with the SUR exercise method.

, Chicago, IL, USA). After half the data (n=15) was collected, a power analysis was done to calculate the number of subjects needed to determine a clinically meaningful difference between exercises. The number of subjects chosen was calculated using G*Power Software (University of Kiel, Berlin, Germany) and was based on an effect size of .
All subjects performed the 3 different exercises, and EMG activity in the SA and UT muscles was recorded during the exercises. The durations of the 3 exercises were controlled by a sound signal generated by a metronome.
In order to examine the SA, the subjects sat on a chair with a backrest to fix the trunk and performed arm elevation in a position between 120° and 130° of flexion.
When the shoulder flexion angle reached 145°, the sliding movement was ended. The subject was instructed to lift both arms until the elbow did not push the target bar but touched it slightly and to maintain the position of the arm for 5 seconds at the end position (Hardwick et al, 2006) (Figure 3).
Manual resistance was applied to the dorsal surface of the subject’s arm, between the shoulder and elbow, downward in the direction of extension. To assess the UT, subjects sat on a chair and performed elevation of the acromial end of the clavicle and scapula. Manual resistance was applied to the subject’s shoulder, in the direction of depression.

이론/모형

Variables were normally distributed, as determined by Kolmogorov-Smirnov tests; thus, parametric statistics were used. Data of this study were expressed as mean±standard deviations.

성능/효과

The results of our study show that the muscle activity of the SA was close to 80 %MVIC and the muscle activity of the UT was only about 50 %MVIC during the SUR exercise. Although the muscle activity of the UT during the SUR exercise was significantly higher than that of the other 2 exercises, previous studies have shown that the UT muscle activity must also be close to its maximum value in order to reach the maximum value of the SA muscle activity; therefore, it may be effective to increase muscle activity of the SA for strengthening of the SA (Decker et al, 1999; Ekstrom et al, 2005).
