Outline of Final Research Achievements	It is very important to grasp the self-posture for improvement of skills in sports. In this study, we develop a method to estimate bike riding posture only from sensors that can be mounted on a bicycle. At first, we developed force measurement systems by using two 6-axis force/torque sensors and strain gauges. Based on the measurement system, we developed a method to estimate handgrip position and a method to estimate upper body posture. Experimental results proved the usefulness of the proposed method.
