Differences in EMG activity during exercises targeting the scapulothoracic region: a preliminary study.

Surface electromyographic response of the middle, lower serratus anterior, and the upper trapezius muscles was investigated within a number of exercises. In total, 16 healthy, physically active volunteers completed three individual trials consisting of arm elevation above 120°, diagonal elevation, dynamic hug, dynamic hug plus, and push-up plus while surface electromyography was used to record muscle activity in the lower and middle serratus anterior (LSA, MSA) and upper trapezius (UT) muscles. The dynamic hug plus exercise caused significant increases in the activity of the MSA compared with the other exercises (P < 0.
