Shoulder pain is one of the most common musculoskeletal conditions among athletes and sports enthusiasts who engage in overhead sports, and it can be highly disabling. Since the shoulder is one of the joints with the greatest range of motion in the human body, it is important to seek strategies that address trunk stability comprehensively to achieve full and effective joint mobility. The central role of the diaphragm in trunk stabilization has been the subject of research for over 50 years, although the exact mechanisms are still not fully understood. The objective of this study is to assess the effects of inspiratory muscle training on diaphragm thickness, inspiratory muscle strength, and shoulder pain in adult tennis players with non-specific shoulder pain. This is a single-blind, randomized controlled clinical trial. The intervention will last for 8 weeks. Patients with non-specific shoulder pain will be randomly assigned to one of two groups. The experimental group will undergo specific inspiratory muscle training, while the control group will receive no specific training intervention. Measurements of diaphragm thickness, inspiratory muscle strength, and shoulder pain will be taken before and after the intervention.
