| Outline of Final Research Achievements |
In this study, the role of the trunk in locomotion during sports was experimentally analyzed by inverse dynamics using motion capture and force plate system. The target motions were the sprint start, the different five speeds of the sprint running, and the direction change motions, and the three-dimensional torques and mechanical work of the pelvis and hip joint were analyzed. At the start, lumbosacral joint extension work was an important source of mechanical energy. The axial rotation torque of the lumbosacral joint during sprinting contributed significantly at a particularly high speed. In the direction change run, the lumbosacral axis rotation torque mainly rotated the pelvis. From this study, the role of the pelvis in locomotion in sports was clarified.
