title: Comparison of Upper Trapezius, Anterior Deltoid, and Serratus Anterior Muscle Activity during Push-up plus Exercise on Slings and a Stable Surface.
abstract: [Purpose] The purpose of this study was to identify effects of push-up plus exercise on different support surfaces on upper extremity muscular activity. [Subjects] The subjects were 28 students (10 males, 18 females) at B University. [Methods] The subjects performed push-up plus exercises either on slings or on a fixed support. [Results] Push-up plus exercises on slings showed significant increases in the muscle activity of the trapezius (upper fiber), deltoid (anterior fiber), and serratus anterior muscles compared with stabilization exercises on a fixed support. [Conclusion] Based on these results, it is considered that performance of the push-up plus exercise on slings will increase scapular muscle activity.
