This study aimed to identify the effect of the push-up plus exercise with sling on the muscle activity and lung function in adults with forward head posture over a period of 8 weeks. A total of 16 adults with forward head posture were recruited. The participants were divided into two groups : control (n-=8) and experimental (n=8). From July 6 until Aug 28, 2015, the participants were instructed to perform the knee push-up plus exercise and knee push-up plus using sling exercise three times a week to begin with and progressing to three sets of push-ups on each occasion after 8 weeks. The participants in both groups showed an increase in their craniovertebral angle (both groups p<0.001) and a decrease in their crania rotation angle (control p<0.05, experimental p<0.001). The participants in both groups showed a decrease in their trapezius activity (both groups p<0.001), an increase in their serratus anterior and lower trapezius muscle activity (both groups p<0.001), (and an increase in their) lung function (control group p<0.01, experimental group p<0.001). These findings show that push-up plus exercise improves posture and increases activation of lung function, while the push-up plus exercise in the sling is more effective in improving the forward head posture. The push-up plus exercise in the sling was more effective in improving the forward head posture, but there was no significant difference in the lung function between the two groups. Therefore, the push-up plus exercise in the sling is recommended as an exercise that is effective for the improvement of the posture and lung function of persons with forward head posture.

The purpose of this study was to compare the shoulder stabilizer muscle activity during a push up plus on a different conditioning surface. Eighteen healthy volunteers were tested. Surface EMG was recorded from the upper trapezius(UT), pectoralis major(PM), and serratus anterior(SA) using surface differential conditions. Measurements were performed for 7 days. The mean root mean square (RMS) of EMG activity was calculated. A one-way repeated measures analysis of variance was performed to compare RMS normalized values. The UT and PM did not show significant differences of electric activation amplitude in relation to different surface conditions(p>.05). However, the SA showed greater mean electric activation amplitude values on the push up plus exercise on a upper and lower unstable surface(p<.05). These results suggest that to improve SA EMG activity is more useful when performed on a upper and lower unstable surface conditions than on a stable surface conditions.

The purpose of this study is to conduct a comparative analysis of the right shoulder's muscle activity when lifting ipsilateral and contralateral legs during the Push Up Plus (PUP) exercise, which is a typical shoulder stabilizing exercise, and to provide effective data for a shoulder stabilization exercise. Upper trapezius, lower trapezius, levator scapula, supraspinatus, infraspinatus, deltoid posterior, serratus anterior and pectoralis major, which are eight main muscles of a shoulder, were analyzed for the left and right leg lifting by using an electromyogram (EMG). The study revealed that the muscle activities of the right shoulder's upper trapezius, levator scapula, supraspinatus, serratus anterior and pectoralis major were higher when lifting an ipsilateral (right side) leg, compared to lifting a contralateral (left side) leg. Therefore, lifting an ipsilateral leg can be an effective method for enhancing the maneuverability (mobility) of the right shoulder when lifting a single leg.

Background: Lumbopelvic stability is highly important for exercise therapy for patients with low back pain and shoulder dysfunction. It can be attained using a pelvic compression belt. Previous studies showed that external pelvic compression (EPC) enhances form closure by reducing sacroiliac joint laxity and selectively strengthens force closure and motor control by reducing the compensatory activity of the stabilizer. In addition, when the pelvic compression belt was placed directly on the anterior superior iliac spine, the laxity of the sacroiliac cephalic joint could be significantly reduced. Objects: This study aimed to compare the effects of EPC on lumbopelvic and shoulder muscle surface electromyography (EMG) activities during push-up plus (PUP) and deadlift (DL) exercise, trunk extensor strength during DL exercise. Methods: Thirty-eight subjects (21 men and 17 women) volunteered to participate in this study. The subjects were instructed to perform PUP and DL with and without the EPC. EMG data were collect from serratus anterior (SA), pectoralis major (PM), erector spinae (ES), and multifidus (MF). Trunk extensor strength were tested in DL exercise. The data were collected during 3 repetitions of all exercise and the mean of root mean square was used for analysis. Results: The EMG activities of the SA and PM were significantly increased in PUP with pelvic compression as compared with PUP without pelvic compression (p<.05). In DL exercise, a significant improvement in trunk extensor strength was observed during DL exercise with pelvic compression (p<.05). Conclusion: The results of this study indicate that lumbopelvic stabilization reinforced with external pelvic compression may be propitious to strengthen PUP in more-active SA and PM muscles. Applying EPC can improve the trunk extensor strength during DL exercise. Our study shows that EPC was beneficial to improve the PUP and DL exercise efficiency.

PURPOSE: This study was conducted to investigate the effects of vibration frequency and amplitude on scapular winging during the knee push-up plus exercise. METHODS: A total of 26 female subjects with scapular winging were evaluated while performing the knee push-up plus exercise with no vibration, low-frequency/low-amplitude (5 Hz/3 mm) vibration, low-frequency/high-amplitude (5 Hz/9 mm) vibration, high-frequency/low-amplitude (15 Hz/3 mm) vibration, and high-frequency/high-amplitude (15 Hz/9 mm) vibration. The surface EMG of the serratus anterior (SA) muscle was compared between the vibration frequency and amplitude. The EMG amplitude was normalized using the maximal voluntary isometric contraction (MVIC). The statistical significance of the results was evaluated using one-way ANOVA. RESULTS: The SA muscle EMG values increased at low-frequency/low-amplitude vibration and at low-frequency/high-amplitude vibration compared to no vibration. Furthermore, the same values increased at high-frequency/low-amplitude vibration and high-frequency/high-amplitude vibration compared to no vibration. In general, a higher vibration frequency and amplitude was associated with higher EMG values of the SA muscle, with particularly greater increases observed during high-frequency/high-amplitude vibration. There was also a significant difference between each condition with a high-frequency/high-amplitude vibration (p<.05). CONCLUSION: This study suggests that there were remarkable clinical effect of the knee push-up plus exercise with vibration, which enhanced the SA muscle activation in persons with scapular winging. Furthermore, applying a higher vibration frequency and amplitude more effectively increased for increasing SA muscle activation.

Purpose : This study was investigated effects of vibration on scapular winging of knee push-up plus exercise. Methods : Twenty-eight female subjects with scapular winging were evaluated after performing knee push-up plus exercise, with or without vibration, three times a week for four weeks. Muscle activation of the serratus anterior and upper trapezius, and the ratio of activation of the upper trapezius to serratus anterior were measured using surface EMG; and scapular winging length was measured by using the caliper. Results : The findings showed that knee push-up plus exercise -with and without- vibration induced a significant increase in muscle activation of serratus anterior (p<.05) and a significant decrease in muscle activation of the upper trapezius (p<.05), the ratio of muscle activation of the upper trapezius to the serratus anterior (p<.05) and scapular winging length (p<.05). There was also a significant difference in muscle activation of the serratus anterior (p<.05) and upper trapezius (p<.05) between control and experimental group at post-test. Conclusion : This study suggests positive clinical effects of knee push-up plus exercise with vibration which enhanced muscle activation of serratus anterior and reduced muscle activation of upper trapezius in person with scapular winging. However, vibration had no effectiveness to improve muscle imbalance between serratus anterior and upper trapezius, and reduce the scapular winging length.

Purpose : The purpose of this study was to find out the effects on muscle activations of serratus anterior and upper trapezius muscles when push-up plus exercise togu applied differently depending on the body part. Method : Thirty six volunteers took part in this study and we divided into three groups(upper arm togu group 12, leg togu group 12, upper arm-leg togu group 12). Each experimental group performed push-up plus exercise. All volunteers received a total of 18 exercise session over a 6 week period (three times per week). Exercise program was composed of serratus anterior and upper trapezius push-up plus exercise. Then we measured muscle activation of scapular stabilizer by electromyography. Repeated ANOVA was used to examine the effects of the intervention on each outcome measure. Result : After the six week intervention, there was a significant difference between the pre and 6 week in serratus anterior and upper trapezius muscle activity(p<0.05). After the six week intervention, there was a significant difference among the three group in serratus anterior muscle activity but no significant difference in upper trapezius muscle activity(p>.05). Conclusion : Serratus anterior and upper trapezius showed high muscle activity during push-up plus exercise. Therefore have a positive impact of scapular stabilizer. The larger the area of the unstable support surface, the larger muscle activity was larger of variation quantity.

Background: The purpose of this study is to examine the effect of push-up plus exercise on the changes in the thickness of the trapezius trapezius, serratus anterior and pectoralis major muscles involved in shoulder stability in various support surfaces. Design: Randomized controlled trial. Methods: The thickness change of the shoulder stabilizing muscle was measured using an ultrasound device. Corresponding t-test was performed to confirm the change within the group before the experiment and after 5 weeks. And one-way ANOVA was used to confirm the change between groups after 5 weeks. As a post hoc test, the least significant difference test was performed, and the significance level was set to a=0.05. Results: Changes in the thickness of the trapezius muscle within the group were significantly different between UPEG and SPEG after 5 weeks (p<0.05), and there was a significant difference between groups after 5 weeks (p<0.05). Changes in the thickness of the serratus anterior and pectoralis major muscle within the group were significantly different after 5 weeks in PEG, UPEG and SPEG (p<0.05), and the changes between the groups were significantly different in the serratus anterior muscle after 5 weeks (p<0.05). Conclusion: From the results of this study, it was found that the push-up exercise on an unstable support surface was effective for strengthening the trapezius upper and serratus anterior. This study intends to suggest the possibility of application as basic data for a push-up plus exercise program in clinical practice.
