Researchers have developed a new method called MS-RFD to automatically detect the precise moment of release in hammer throw events using reconstructed 3D trajectories. This technique integrates four key kinematic signals: speed dynamics, angular velocity transition, radial distance from the rotation center, and post-release trajectory linearity. An ablation study indicated that speed dynamics and radial expansion are the most crucial signals for accurate release frame detection, with angular velocity and linearity offering minor improvements.
