Abstract

Purpose: This study aimed to provide a scientific basis for effects of the push-up plus exercise program on scapular position and on muscle activity in individuals with rounded shoulder posture (RSP). Methods: The supine method was applied to 46 potential subjects, of which 30 with RSP were selected. Subjects with RSP were divided into two groups: a gender push-up plus group as the experimental group a pectoralis minor self.stretch group as the control group. RSP data after 4 weeks of each intervention were obtained and analyzed to measure the activities of the 3 muscles. Results: The two groups differed significantly with regard to EMG changes in the serratus anterior (p<0.05). The EMG results indicated a significant reduction in the activity of the upper trapezius in the experimental group (p<0.05). EMG results indicated a significant increase in the activity of the serratus anterior after the intervention (p<0.05). EMG results of the subjects in the control group indicated that the activity of the upper trapezius significantly decreased (p<0.05). The RSP values of the subjects in both groups were significantly decreased (p<0.00). Conclusion: An improvement in the strength of the serratus anterior, and in the stretch effectiveness of the pectoralis minor, as well as changes in the scapular position were observed after 4 weeks of push-up plus exercise by the subjects.
