| Outline of Final Research Achievements |
The role of torsional rotation and axis of trunk have not been investigated from a viewpoint of biomechanics during dynamic sport motions, like sprint running, throwing, etc. Then, this study focused the mechanism of trunk motion in human. The 2-segment model which consists of upper and lower trunks was adopted to examine during trunk rotation in standing. In this study, the energy transfer and production/absorption of mechanical work at pin-joint of trunk were analyzed. The 3-segment model which consists of upper, middle and lower trunks was adopted to examine during walking and jogging. The mechanism of trunk was understood during human locomotion. Furthermore, the detail simulation method was developed to estimate the torque/power in each joint of the body, in order to improve the personal performance.
