The trunk muscles include the abdominal and scapular muscles, and strengthening them improves trunk stability. We investigated the effect of scapular strengthening exercise with and without band on trunk muscles and abdominal muscles activities. In 34 healthy men, scapular strengthening exercises A (scapular adduction) and B (scapular adduction with shoulder external rotation) with and without bands were applied. Electromyography was used to measure the muscle activity of latissimus dorsi (LD), lower trapezius, and erector spinae, and ultrasonography were used to measure the thickness of the abdominal muscles. Muscle activity was measured during the motion and during maintaining it, and muscle thickness was measured during maintaining the motion. As a result, LD activity was the highest in scapular strengthening exercise A with band, and there was no significant difference in abdominal muscle thickness with or without band. Therefore, scapular strengthening exercise A with band is considered to be the most effective method to improve LD activity.
