Abstract

[Purpose] This study investigated the effect of different leg angles during push-up plus exercise on shoulder stabilization muscle activity. [Participants and Methods] Fifteen healthy adult males participated in this study. The smart phone application Clinometer was used to measure leg angles of 70°, 90°, and 110° during push-up plus exercise. The muscle activities of the serratus anterior, upper trapezius fibers, and pectoralis major muscles involved in shoulder stabilization were analyzed using surface electromyogram. [Results] Leg angle significantly affected serratus anterior muscle activity, but it did not affect activities of the upper trapezius fibers or pectoralis major muscles. Post-hoc analysis revealed that serratus anterior muscle activity at the leg angle of 110° was significantly higher than at leg angles of 70° and 90°. [Conclusion] A higher leg angle during push-up plus exercise is a more effective intervention for the serratus anterior muscle activity.
