| Outline | A wavy limb movement called "whipping motion" is observed in throwing or hitting actions. This project illustrates the mechanical properties of swing motion from the computational analyses such as inverse dynamics and energy flow. The project now expands into outreach activities for supporting athletes and coaches. |
