중학생의 둥근어깨 교정운동프로그램과 가정운동프로그램이 어깨 높이와 등세모근의 근활성도 및 집중력에 미치는 영향

Abstract

Purpose: The purpose of this study was to investigate the effects of home exercise program and exercise program of round shoulder adjustments on the level of trapezius muscle activity and attention capacity for middle school students. Method: The participants in this study were composed of 21 middle school students. We made the students lie on the floor in prone position, then measured the height of their acromion from the floor. We chose participants for our study whose measurement values were over 2.5cm. We divided them into two groups, one is for the experimental group, and the other is for the control group. The experimental group exercised three days a week for 6 weeks, including home training, and the control group didn`t exercise. We used EMG to measure the trapezius muscle`s activity and used a Stroop test for the measurement of the students` attention capacity. Results: The results of our study are as follows. There was no significant difference between the experimental group and the control group. However, there was a significant difference within the experimental group when comparing pre and post training results for Trapezius muscle activity and attention capacity. Conclusion: We found that correcting round shoulder symptom increases the Trapezius muscle activity and students` attention capacity. Future experiments should investigate with systemical management. Also, we need to increase the frequency of the exercise and participants.
