Currently, manned space exploration is actively being promoted internationally, so it is necessary to clarify kinematic changes of locomotion under microgravity. In this research, walking in a microgravity environment was simulated by using an anti-gravity treadmill and its walking motion was measured with a wearable motion measurement device. As a result, it was found that it becomes floating and slower tiptoe walk as the weight rate is small from ground reaction forces and joint angles, and the walking behavior characteristics of a lower body greatly changes between the weight rate of 40% and 60% from the joint angles.
