Objectives

Narrative objectives1

In this research, focusing on the step width at pitching, we clarify the difference in step width between male players and female players. By further verifying the difference between the ball speed and the pitching motion when changing the step width, we will improve the competitiveness of the female baseball player and help prevent the disability.
