A 2025 study published in the Journal of Biomechanics compared shoulder kinematics measured with Theia3D markerless motion capture against gold-standard marker-based motion capture across full arm ranges of motion. The results show strong agreement for many movements, particularly in the coronal plane, while also highlighting where caution is still required, especially at the extremes of ranges of motion and in transverse-plane rotations.

Baseball tracking systems can measure everything from ball flight and bat path to workload and full-body biomechanics, but each category answers a different question. This guide compares leading options and explains how to choose the right system based on what your program needs to measure, where it will operate, and whether it can connect athlete mechanics to baseball outcomes.

Choosing motion analysis software depends on more than whether it can track movement. This guide compares leading tools by output type, setup complexity, validation, data ownership, and workflow fit so research and performance teams can choose the right system for their needs.
