AB - PURPOSE: This study was to determine the effect of the plane of movement (sagittal plane vs. scapular plane) and shoulder flexion angle (90° vs. 130°) during scapular protraction exercises in healthy subjects by investigating the elecromyographic (EMG) activities of the serratus anterior (SA), upper trapezius (UT), and pectoralis major (PM).
METHODS: Twenty-one healthy subjects participated in this study. Subjects performed maximal scapular protraction at the 90° or 130° shoulder flexion angles in the sagittal or scapular planes. Surface EMG was recorded from the SA and UT, and PM muscles. Dependent variables were examined by 2 (plane) × 2 (angle) repeated measures of analysis of variance (ANOVA).
RESULTS: Significantly increased EMG activities in theSA and UT were found during scapular protraction exercise at the 130° shoulder flexion angle in the sagittal and scapular plane. Also, EMG activity of the PM significantly decreased at the 130° shoulder flexion angle in the sagittal plane and the 90° and 130° shoulder flexion in the scapular plane.
CONCLUSION: we recommend scapular protraction exercise at the 90° shoulder flexion in the sagittal plane to selectively strengthen the SA muscle with limitation of upper trapezius activity and at the 130° shoulder flexion in the scapular plane to selectively strengthen the SA muscle with limitation of pectoralis major activity.
