The standing-up motion of young male was evaluated using kinematics, force plate, and electromyograph data. The standing-up motion without over bending body is rapidly and dynamically, dynamic strategy, while the motion with over-bending body is slowly and statically, static strategy. Moreover, Electromyogram (EMG) on rectus femoris and tibialis anterior muscles during dynamic strategy was very higher than that during static strategy. Role of rectus femoris and tibialis anterior during the motion are different. The former contribute to increase acceleration due to dynamic contraction. The latter maintain body balance due to defy gravity. To attain dynamic strategy is to keep rectus femoris and tibialis anterior muscles strong.
