A new study found that high school pitchers with a more forward shoulder posture at rest showed less efficient scapular movement and relied on greater muscle activation during the throwing motion. While the research doesn't prove that poor posture causes injury, it suggests that simple posture assessments may help identify athletes who are compensating before pain or symptoms appear. The takeaway is that shoulder posture isn't just about how an athlete stands—it may influence how efficiently and safely they throw.
