The purpose of this study was to investigate the effect of the latissmus dorsi exercise method on the muscle activity of the latissimus dorsi and posterior deltoid. During lateral pull-down exercise, the muscle activity of the latissmus dorsi and posterior deltoid in 30 healthy men were measured in accordance with the shoulder extension angle. The results showed that the muscle activity of the left posterior deltoid was not significantly different according to the shoulder extension angle. The muscle activities of the right posterior deltoid and latissmus dorsi were significantly different according to the shoulder extension angle. In our results, we identified that lateral pull-down exercise reduced shoulder joint instability and lesion occurrence in shoulder joint 0° extension.
