Abstract
Purpose : The purpose of this study was to examine activities of the scapular stabilizers during push-up plus and PNF backward rocking exercises. Methods : 9 subjects performed randomly push-up plus and PNF backward rocking exercises in four point kneeling. The activities of 4 scapular stabilizing muscles were compared between push-up plus and PNF backward rocking exercises. Results : PNF backward rocking exercise showed significantly higher lower trapezius and lower serratus anterior activations compared to push-up plus exercise. Push-up plus exercise showed significantly higher middle serratus anterior activation than PNF backward rocking exercise. Conclusion : PNF backward rocking exercise facilitates the lower trapezius and serratus anterior activations compared to push-up plus exercise.
