The Effect of Modified Push-up Exercise Using Electromyography Biofeedback on Selection of Scapular Stabilizing Muscles

Background: The serratus anterior (SA) muscle is an important scapular stabilizer and has a profound role in retaining the scapulohumeral rhythm. Therefore, modified push-up plus (MPUP) been advised to strengthen this as closed chain workout. However, few previous studies have reported possibility of reparative motion from pectoralis major (PM) that could replace amend SA's function during plus. Objectives: current study examined MPUP's effect using biofeedback EMG on some selected stabilizers. Methods: Sixteen healthy young subjects voluntarily participated study. Each subject performed push-ups, quadruped position, under two conditions (i.e., with or without visual auditory biofeedback). Surface measured major, anterior, upper trapezius activity. A paired t-test was used determine any statistically significant difference between conditions. Additionally, size calculated quantify magnitude each muscle. Results: MPUP training significantly increased SA activity decreased PM activity, but there no change UT Conclusions: Excessive repressed because biofeedback, workout done enhancement muscular Thus, including while doing MPUPs helps limit PM's supplementary action enhance
