A new study on 75 Dominican MLB prospects revealed that nearly every athlete—average age just 17.9—already showed shoulder and elbow changes typically seen in seasoned professionals. Despite being pain-free, most had partial UCL tears, labral fraying, or rotator cuff tendinosis, underscoring how early specialization and nonstop training accelerate physical adaptation. At VeloU, we use findings like this to reinforce our belief that the goal isn’t to avoid adaptation, but to manage its pace—because long-term velocity and health depend on structured progression, not constant exposure.
