Abstract

Purpose : This study according to the angle at the shoulder joint abduction compare muscle activity by analyzing abduction in normal depending on the angle of the shoulder joint which muscles are activated exactly know what its purpose is. Methods : 15 students with a healthy shoulder abduction angles ($45^{\circ}$, $90^{\circ}$) according to the trapezius (upper, midder, lower), infrasupinatus, deltoid, pectoralis major, serratus anterior, latissimus dorsi muscle activity of the were analyzed. How the% MVIC EMG activity of each muscle EMG signals were standardized. Results : The mean age of the study subjects 23.6 years old, and is a key 175.6Cm, weight 70.66Kg respectively. $45^{\circ}$ non-load Pectoralis major, load Deltoid, $90^{\circ}$ non-load Deltoid, Latissimus dorsi load showed the most activity. Conclusion : The purpose of this study the muscle activity of the muscles in order to mobilize the comparison of the active muscles, but the experimenter with a range of individual differences that every time I was able to find the average. Based on these results will be helpful in future studies.
