| Outline of Final Research Achievements |
The purpose of this study was to develop a computer simulation model of the upper body (angle-driven) with the standard motion model to explore the effect on the swing motion by changing its initial configuration in baseball batting. A standard motion model included 10 participants in baseball tee batting was created,and then an upper body computer simulation model (angle-driven) with the created one was developed. The optimization procedures were carried out as follows: 1) minimum distance of the bat-head, 2) maximum angle of the bat longitudinal axis, and 3) minimum angle of the bat longitudinal axis.
For the upper limbs, the angles of the shoulder flexion/extension and wrist radius/ulnar flexion of the barrel-side, and that of the shoulder flexion/extension of the knob-side showed large differences with the measured motion.
