The Effect of Wall Slide Exercise using AB-SLIDE on The EMG Activity of Serratus Anterior and Upper Trapezius

Background It is known that a wall slide exercise is required to strengthen the serratus anterior. However, overactivation of the upper trapezius during wall slide exercise reduces serratus anterior mus-cle activation. Currently, methods to strengthen the serratus anterior muscle during wall slide exercise are being studied. However, there is no study that wall slide exercise using AB-SLIDE the affects upper trapezius and serratus anterior muscle. Objectives The purpose of this study is to compare the upper trapezius and serratus anterior muscle activity between general wall slide exercise and wall slide exercise using AB-SLIDE. Methods A total of 15 healthy male volunteers were recruited for this study. With and without AB-SLIDE, muscle activity of the upper trapezius and serratus anterior was compared during the wall slide exercise. The electromyographic data of the upper trapezius and serratus anterior was measured using 4D-MT, 2EM. The difference between general wall slide and wall slide using AB-SLIDE was ana-lyzed using the paired t-test with p < 0.05 as a significant level. Results Compared to the general wall slide exercise the upper trapezius muscle activation was sig-nificantly decreased when wall slide exercise using AB-SLIDE(p < 0.05). Also, serratus anterior muscle activation was significantly increased when wall slide exercise using AB-SLIDE (p < 0.05). Conclusions In this study, compared to general wall slide exercise, the upper trapezius muscle activity was significantly decreased and serratus anterior muscle activity significantly increased when using AB-SLIDE. The result of this study can confirm the wall slide exercise using AB-SLIDE will be a useful way to increase the muscle activity of the serratus anterior.
