Purpose : The purpose of this study was to investigate the effects of quadruped exercise and wall slide exercise on the shoulder height and Specific muscle activity of college students with round shoulders.
Methods : Participants in this study consist of 20 college students. We selected students with a height of 2.5 cm or more from the table to the back of the shoulder acromion in a straight posture(supine) as participants in the study. Participants were trained for three days a week for 4 weeks, The muscle activity of the upper trapezius, lower trapezius, and sternocleidomastoid muscle, serratus anterior were measured using the surface EMG MPl50 WSW (Surface EMG) and difference in shoulder height was measured.
Results : The results of this study are as follows. Comparison of shoulder height before and after exercise showed a significant decrease. Maximal voluntary isometric contraction results showed that muscle activity of the upper trapezius and sternocleidomastoid muscle was significantly decreased and muscle activity of the lower trapezius and serratus anterior was significantly increased.
Conclusion : The exercise of this study is effective in decreasing shoulder height of a person with a round shoulder and increasing or decreasing the activity of the shoulder muscles. It can be said that to effective effect on prevention of secondary damage to the shoulders of students and workers who live in a sitting position, or to improve the incorrect position. In future studies, systematic and specific research methods are needed and the frequency of exercise and participants should be increased.
