Abstract

<p>The purpose of this study was to analyze the impact of a short pitching interval of 3 days on throwing motion and ball speed.</p><p>The subject was a pitcher who threw a complete game (99 pitches) in the official semifinal baseball game for school-age children, as well as another game (110 pitches) in the final after a pitching interval of 3 days. The method was two-dimensional motion analysis using a high-speed camera.</p><p>The results revealed that the pitcherʼs throwing motion and ball speed were generally stable in the semifinal,but markedly worsened from the 51st pitch in the final, which may have allowed the opponent team to score several runs.</p><p>The pitcherʼs worsened throwing motions and ball speed suggest that a pitching interval of 3 days is not adequate to for recover from fatigue due to excessive pitching in the semifinal.</p>
