「捻りモデル」から考察するテッド・ウイリアムズの「バッティングの科学」--力を生み出すメカニズムと理論の応用について

抄録

The Science of Hitting by Ted Williams is an excellent book. Ted Williams wrote everything about hitting he obtained through his career in this book. However his explanation on hitting mechanics is vague for it is based on his personal perception. Recently I surprisingly found that by applying the Twisting Model theory, his explanation on the hitting mechanics becomes a lot clear and helped for better understanding regarding movement and property of power produced. In this article I would like to introduce the "Twisting Model" and by using physical approach I would like to show how the Twisting Model supports Williams.
