Effort-dependent effects on uniform and diverse muscle activity features in skilled pitching

Abstract How do skilled players change their motion patterns depending on motion effort? Pitchers commonly accelerate wrist and elbow joint rotations via proximal joint motions. Contrastingly, they show individually different pitching motions, such as in wind-up or follow-through. Despite the genera...
