A Study on Dynamic Balance of Straight Arm Press to Handstand with Legs Together

Abstract

Dynamic balance from straight arm press to handstand with legs together in gymnastics is investigated by constructing a motor control model and measuring the movement. Simulation results showed that the handstand movement where the center of mass is lifted strictly along the vertical axis can be achieved by slightly shifting the center of pressure back and forth while maintaining the floor reaction force in the vertical direction. Based on the simulation and measurement results, the static and dynamic components of the torque around the wrist joint and the torque around the center of mass were confirmed.
