野球の打撃動作の改善 : ―ボールへの視点から―

Abstract

In this experiment baseball balls were marked with a black 5 mm dot. The purpose of the study was to determine whether or not a hitting method in which batters focus on the ball’s black dot while swinging the bat contributes to producing inside-out swings. Eight high school baseball team players were the subjects of this study. The main results were as follows: 1. The path drawn by a bat grip on a swing was shortened when this hitting method was employed, indicating shifts from ordinary to inside-out swings. 2. The distance between bat grip and ball at bat-ball impact was shortened by 3 cm. 3. The explanation of these results could be that focusing the sight on the dot makes the batter aim at the dot when striking the ball. This hitting method may be utilized in actual training of baseball players.
