Abstract

The abnormal movements often occur in shoulder region and they cause pains commonly. This study aimed to determine the most effective exercise to strengthen the subscapularis selectively among Lift off, Belly press and Prone wiper by investigating each exercise’s influence on muscle thickness. Forty subjects performed all exercises randomly. Before and after exercises, the muscle thickness was measured with an ultrasound. Paired t-test was used to compare the changes between before and after each exercise. One-way ANOVA was used to compare the effects among three exercises. The thickness of the subscapularis was significantly increased by all exercises. The thickness of the infraspinatus was significantly decreased by the Belly press, but significantly increased by the Lift off and the Prone wiper. More effective internal rotation performance was achieved by the Belly press than the other exercises. In conclusion, the Belly press is considered more effective to strengthen the subscapularis selectively.
