In order to understand human motor function, it is necessary to clarify how humans achieve adaptive motions regarding to external environment or their own purpose. This study analyzes human standing-up motion in different chair seat heights and motion speeds using muscle synergy analysis to find important modules to achieve the movement. Muscle synergy is determined from measured eight muscle activations (<i>n</i>=10), and relationship between muscle synergy and body kinematics is clarified. As a result, invariant three muscle synergies were found in human standing-up motion regardless of different seat heights and motion speeds. On the other hand, amplitude and duration of time-varying activation of muscle synergies were properly adujusted to enviromental change. Moreover, it was observed that time-varying activations were strongly corresponded to characteristic kinematic event of standing-up motion. This result implies that humans can achieve the adaptive standing-up motion mainly by controlling time-varying activation of three muscle synergies.
