In baseball pitching, pitcher's trunk has several functions for conveying the movement energy from the lower limb to the upper limb. The stretching of the chest is known to be one of such functions, which is usually used for baseball coaching. Its biomechanical meaning, however, is still unclear, consequently being used in a broad sense. In order to use the term clearly and effectively in the coaching, we have to establish a quantitative evaluation of the stretching of the chest. Then, this paper proposed a novel evaluation parameter using the curvature of the thoracic spine. Anatomical and motion experiments using an open-MR system and an optical motion-capture system respectively suggested that the proposed parameter could be dependent primarily to the stretching of the chest in the baseball pitching, while being independent from other components of the motion. |
