The Effects of Intensive Serratus Anterior and Lower Trapezius Muscle Training with Thera-band on Muscle Activation, Height of Shoulder in People with Rounded Shoulder

Abstract

Purpose This study was to investigated the effect of intensive serratus anterior muscle and lower trapezius muscle training with Theraband on muscle activation and height of shoulder in people with round shoulder. Method Sixteen students with rounded shoulder were recruited in D college and randomly allocated both groups. Both serratus anterior training group(n=8) and lower trapezius group(n=8) were performed intensive muscle training with Theraband for 6 weeks(10 sessions/time, 3times/week, total 18 times). We measured height of shoulder and muscle activation with EMG MR 3.8 software(NORAXON Desktop DTS, USA) for comparing the results of prepost training. Result There were significant difference on scapular height and muscle activation in both serratus anterior group and lower trapezius group(p<0.05). However, in correlation between height of shoulder and muscle activation, we could not find significant difference in both group(p>0.05). Conclusion This study indicated that both of serratus anterior muscle and lower trapezius muscle intensive training using Theraband effect the improvement rounded shoulder in college students.
