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.
Key words: Push-up plus exercise, Sling, Muscle activity
